This refers to the following activities: Road transportation Application and set-up work Operation Maintenance Troubleshooting and repair Operators trained by HORSCH Furthermore, for certain activities the corresponding personnel must have been trained by service personnel from HORSCH. This refers to the following activities: Loading and transport Commissioning Troubleshooting and repair Waste disposal Certain work concerning maintenance and repair must only be carried out by an expert workshop. Such work is identified with the additional comment "Workshop work". Children in danger Children are not able to assess dangers and may behave unpredictably. Children are therefore especially endangered: ¾Keep children away from the machine. ¾ Especially when starting to drive and before triggering machine movements you must make sure that the danger zone is free of children. ¾ Shut down the tractor before leaving it. Children can trigger dangerous machine movements. An insufficiently secured machine parked without being attended poses a danger for playing children! 7

12 Personal protective outfit Missing or incomplete protective equipment increases the risk of health damage. Personal protective equipment includes, e.g.: ¾ Tight fitting clothes / protective clothing, possibly a hair net ¾Safety shoes, protective gloves ¾ Safety goggles to protect the eyes against dust or spray, when working with fertiliser or liquid fertiliser (follow the instructions of the fertiliser manufacturer) ¾ Respiratory masks and protective gloves when handling dressing or dressed seed (follow the instructions of the pickling agent manufacturers) ¾ Determine the personal protective equipment for the corresponding work place. ¾ Provide effective protective equipment in proper condition. ¾Never wear rings, bracelets or other jewellery. Safety in traffic DANGER No passengers are allowed to ride on the machine! ¾ Pay attention to the permissible transport widths and heights. Pay attention to the transport height when passing under bridges and low hanging overhead power lines. ¾ Do not exceed the permissible axle loads, tyre load bearing capacities and total weights, in order to ensure sufficient steering and braking capabilities. The front axle must be loaded with at least 20 % of the tractor weight. ¾ Clean soil from the folding areas before folding up. Otherwise there could be damage to the mechanics. ¾ If present: Secure the hydraulic cylinders on undercarriage and drawbar in transport position against uncontrolled movements using aluminium clips, see chapter Connecting and transport position. ¾ Assemble lighting, warning and protective features and check the function. ¾ Before driving on roads clean the entire machine from picked up dirt. Handling is affected by the connected equipment. ¾Consider the wide overhang and the centrifugal mass of the implement as well as the filling capacities, especially when cornering. Raised machine (Three-point hydraulics): ¾ Consider the limited stability and steerability of the tractor. For transport on public roads, only drive with empty seed hopper. For transport on public roads pay attention to the permissible top speed mentioned in the operating licence! The specifications in the type approval document or in the technical data are decisive for the design dependent top speed. Always match the travel mode to the road conditions to avoid accidents and damage to the undercarriage. Consider your personal abilities, carriage way, traffic, sight and weather conditions. For road transport the machine must be set to transport position. The machine must have been folded up and secured, see chapter "Folding" and "Hitching up and transport position". 8

13 Safety in operation Commissioning The operational safety of the machine cannot be guaranteed without an orderly performed commissioning. This can lead to accidents with severe or even fatal physical injuries. ¾ The machine must only be put into operation after receiving instructions by employees of the authorized dealer or a HORSCH employee. ¾The machine registration form must be completed and returned to HORSCH. All protective features and safety equipment, such as detachable protective devices (wheel chocks, etc.), must be correctly in place and reliably functioning before the machine is put into operation. ¾ Check nuts and bolts, especially the ones on wheels and cultivation tools regularly for tight fit and retighten if necessary. ¾ Check the tyre pressure at regular intervals, see maintenance overview. Damage to the machine Damage to the machine can impair the operational safety of the machine and cause accidents. This can lead to severe or even fatal physical injuries. The following machine parts are particularly important for safety: If in doubt about the safety relevant status of the machine, e.g. in case of leaking out operating fluids, visible damage or unexpected changes in travel behaviour: ¾ Immediately shut down and secure the machine. ¾ If possible locate and rectify the faults by following these operating instructions. ¾Rectify possible causes for damage (e.g. remove coarse dirt and tighten loose screws). ¾ Have damage, that could affect safety and that cannot be rectified by yourself, rectified by a qualified expert workshop. Hitching and unhitching Faulty coupling of the machine to the pulling tool of the tractor causes dangers, which could result in severe accidents. ¾Strictly comply with all operating instructions: These operating instructions (chapter "Connecting and transport position" and "Parking") Operating instructions of the tractor ¾ Exercise special caution when reversing the tractor. Never stand between tractor and machine. ¾ Only park the machine on a firm and level surface. Before unhitching the towed machine, lower it to the ground. ¾ Secure the machine against rolling away. ¾Hydraulics ¾Brakes (if available) ¾Connecting features ¾Protective features ¾ Lighting 9

14 Hydraulics The hydraulic system is under high pressure. Escaping fluid can penetrate the skin and cause serious injuries. In the event of injury, consult a doctor immediately. The machine's hydraulic system has several functions, which can cause injury to persons or damage to the machine if operated incorrectly. ¾ Connect hydraulic hoses to the tractor only when hydraulic system on tractor and machine are depressurised. ¾ The hydraulic system is under high pressure. Check all lines, hoses and screwed connections regularly for leaks and any visible external damage! ¾ Use only appropriate means when searching for leaks. Repair any damage immediately! Oil sprays can cause injuries and fire! ¾Power sockets and connectors on the hydraulic connections should be marked in order to exclude operating errors. ¾ In the case of injury, contact a doctor immediately! ¾ Secure and lock the control unit on the tractor if not in use! ¾ Replace hydraulic hoses at the latest after six years, see "Maintenance overview". Pressure accumulator The hydraulic system may be equipped with pressure accumulators. ¾ Do not open or work (welding, drilling) on pressure accumulators. Even when empty, the tanks are still preloaded by gas pressure. The hydraulic system must be depressurized before maintenance! Brake system Depending on the equipment, the machines can be equipped with a pneumatically or hydraulically operated service brake system. For road travel the brake system must always be connected and fully functional. ¾After hitching the machine and before transportation you should always check the function and condition of the brake system. ¾ Check the setting on the brake pressure regulator. ¾Always release the parking brake before starting to drive. ¾ Always secure the machine against rolling away and apply the parking brake before unhitching. Adjustments and repair work on the brake system must only be carried out in a professional workshop or by an operator, who has been specially trained by HORSCH for this purpose. Overhead lines When unfolding or folding the wings, the machine may reach the height of overhead power lines. Possible voltage flashover to the machine causing fatal electric shock or fire. ¾ Keep a safe distance to electric high voltage power lines with the folded up machine or when unfolding or folding the machine. ¾ Do not unfold or fold the wings in the vicinity of pylons and power lines. ¾ Never leave or access the machine under overhead power lines to avoid possible risks of electric shock or voltage flashover. 10

15 What to do in case of voltage flashover Voltage flashover generates high electric voltages on the outside of the machine. This results in extreme voltage differences at the ground around the machine. Wide strides, laying on the ground or supporting yourself with your hands on the ground can cause life-threatening electric currents (pace voltage). ¾ Do not leave the cabin. ¾ Do not touch any metal objects. ¾ Do not create a conductive connection to ground. ¾ Warn persons: DO NOT come near the machine. Electric voltages at the ground can cause severe electric shock. ¾ Wait for professional rescuers. The overhead power line needs to be switched off. If persons need to leave the cabin despite the voltage flashover, e.g. in case of a potential lifethreatening risk of fire: ¾ Jump away from the machine. Ensure a safe stand when jumping. Do not touch the outside of the machine. ¾ Move away from the machine with short stepping strides. Technical limiting values If the technical limiting values of the machine are not complied with, the machine may get damaged. This can lead to accidents with severe or even fatal physical injuries. The following technical limiting values are of particular importance for safety: permissible total weight maximum axle loads maximum drawbar load top speed See chapter "Technical data", type plate and type approval. Use in the field DANGER No passengers are allowed to ride on the machine! ¾ Check the area around the machine (for children!) before driving off and commissioning of the machine. Ensure sufficient visibility. ¾ Ensure sufficient stability of the machine in case of longitudinal or transverse inclination when working in uneven terrain. Pay attention to the limiting values for the tractor. ¾ Do not remove any of the mandatory and supplied protective devices. ¾ Stay clear of the operating range of hydraulically operated parts. ¾ Do not drive backwards with the machine lowered. The components have only been designed for forward travel in the field and may be damaged when reversing. Changing equipment / wear items ¾Secure the machine against unintended rolling away! ¾ Secure raised frame parts you have to work under with suitable supports! ¾ Caution! Danger of injury caused by projecting parts (e.g. coulters)! Do not use packer tyres or other rotating parts to climb on the machine. These could rotate and you could be seriously injured by falling down. ¾ Also pay attention to the max. permitted loads for the tractor. 11

16 Fertiliser and dressed seed Inappropriate handling of fertiliser and dressed seed can cause poisoning and death. ¾ Follow the information given in the safety data sheet of the manufacturer. If necessary ask the dealer for the corresponding safety data sheet. ¾ Determine and provide the personal protective outfit as specified by the manufacturer. Environmental protection Operating materials such as hydraulic oil, lubricants, etc. can damage the environment and the health of persons. ¾ Do not allow operating materials to drain out into the environment. ¾ Take up drained operating materials with absorbent material or sand, fill it into a leak tight tank and dispose of in accordance with statutory regulations. Retrofits Structural changes and extensions can adversely affect the functionality and the operational safety of the machine. This can lead to severe or even fatal physical injuries. ¾ Do not make any structural changes or extensions to the machine that have not been approved by HORSCH. ¾ Structural changes and extensions must only be made in an authorized workshop or by an operator who has been trained by HORSCH. ¾ Comply with country specific instructions for weights, weight distribution and dimensions. For equipment influencing the weight or weight distribution one must check and comply with the regulations concerning towing facilities, support and axle loads. For machines without brakes a brake system may need to be retrofitted if the permissible weight limits are exceeded. In case of changes concerning data mentioned on the type plate, a new type plate with updated data must be attached. In case of changes which concern the data in the type approval, this type approval needs to be renewed. 12

17 Care and maintenance Inappropriate care and maintenance puts the operational safety of the machine at risk. This can lead to accidents with severe or even fatal physical injuries. ¾Conform with prescribed schedules for repetitive tests or inspections. ¾ Service the machine according to the maintenance plan, see chapter "Care and maintenance". ¾ Only perform the work described in these operating instructions. ¾ Before starting maintenance and service work park the machine on level and firm ground and secure it against rolling away. ¾ De-pressurise the hydraulic system and lower or support the implement. ¾ Prior to working on the electrical system, disconnect it from the electric current supply. ¾ When performing welding work on the machine, disconnect the cables from computers and other electronic components. The ground connection must be as close as possible to the welding point. ¾Before cleaning the machine with high pressure cleaning equipment cover all openings, which should stay clear of water, steam or cleaning agents for reasons of safety or operation. Do not aim the water jet directly on electric or electronic parts, on bearings or the fan.when using high pressure or steam cleaning equipment, you should always keep an at least 50 cm distance from such machine parts. ¾ After cleaning, check all hydraulic lines for leaks and loose connections. ¾ Check for chafing and signs of other damage. Remedy any faults immediately! ¾ Screw connections loosened for the purpose of care and maintenance work must be retighten after work is completed. ¾ All other maintenance and repair tasks, which are not described in the operating instructions, must only be carried out by an authorized professional workshop or by an operator who has been trained by HORSCH for this purpose. Do not clean new machines with a steam jet of a high pressure cleaner. The paint takes approx. 3 months to cure and could thus be damaged if this time has not yet expired. 13

18 Danger zone The area marked red indicates the danger zone of the machine: The danger zone around the machine poses the following endangerments: Failing to pay attention to the danger zone can result in severe or even fatal physical injuries. ¾ Do not stand under lifted loads. Lower such loads to the ground first. ¾ Instruct persons to leave the danger zone around the machine and tractor. ¾ Before working in the danger zone of the machine or between machine and tractor: Shut down the tractor! This also applies for short-term inspection work. Many accidents happen because of carelessness and running machines! ¾Pay attention to the information in all operating instructions. Accidental operation of the hydraulic system can trigger dangerous movements of the machine. Defective or not correctly fastened electric lines can cause electric shocks. With the drive still running, machine parts may rotate or swing out. Hydraulically raised machine parts can lower slowly and unnoticed. 14

19 Safety stickers Safety stickers on the machine warn of hazards at dangerous points and are an important part of the safety equipment of the machine. Missing safety stickers increase the risk of severe or even fatal injuries. ¾Clean soiled safety stickers. ¾ Damaged or illegible safety stickers must be replaced immediately. ¾ Affix the specified safety stickers on spare parts. No passengers are allowed to ride on the machine! Stay clear of the operating range of foldable machine parts! Before commissioning the machine you need to read and follow the operating instructions!

22 Commissioning NOTE These work activities may be carried out only by persons trained by HORSCH for this purpose. WARNING Increased danger of accidents during commissioning. ¾ Observe the notes in the safety chapter. Delivery The machine with implements is normally delivered completely assembled on a low loader. If parts or assembly groups had to be disassembled for transport purposes, these will be assembled locally by our distributor or field technician. Depending on the design of the low loader the machine can be unloaded with a tractor, or needs to be lifted off with suitable lifting gear (forklift truck or crane). ¾ Use only lifting equipment and lifting gear with adequate lifting capacity and approval! Lifting and lashing points are identified by labels. When using other lifting points pay careful attention to the centre of gravity and the weight distribution. These points must, in any case, only be on the frame of the machine. Machines with E-Manager On machines with the E-Manager drill controls the hydraulic function "Lift/Lower" is possible without any additional installation work. These machines can be unloaded from the low loader without having to install the basic equipment beforehand. The other hydraulic functions such as "Folding" or "Bout marker" can only be operated after the basic equipment has been installed on the tractor. Transport Depending on country-specific regulations and working width the equipment can be transported on public roads either attached to a tractor or on a trailer or low loader. ¾ The permissible dimensions and weights for transport must be complied with. ¾ The tractor must be large enough so that sufficient steering and braking abilities are ensured. ¾ If the machine is hitched up in two-point mode, the tractor link arms must be blocked against swinging sideways. ¾ On a trailer or low loader the machine must be secured with tensioning straps or other means. ¾ Attach lifting tackle only at the specially marked points. Installation Instruction of the operator and initial installation of the machine will be carried out by our service engineers or distributors. Any prior use of the machine is prohibited The machine can only be released for operation after the instruction session conducted by our service engineer / distributor and after the operating instructions have been read. WARNING Increased danger of accidents during installation and maintenance. ¾ Read these operating instructions and become acquainted with the machine before starting this work. Depending on scope of equipment ¾Take loose parts supplied off the machine! ¾ Remove all parts from the hoppers. ¾Check all important screw connections! ¾Lubricate all grease nipples! ¾ Check air pressure in tyres. ¾ Check all hydraulic connections and hoses for correct fastening and function! ¾ Immediately rectify any occurring damage or have it corrected!

26 Calculating the ballasting Required data: The permissible total weight, the permissible axle loads and the load bearing capacity of the tyres must not be exceeded when mounting or hitching up implements. The front axle of the tractor must always be loaded with at least 20 % of the curb weight of the tractor. ¾ Before transportation on public roads you must make sure that the tractor is not overloaded and suitable for this implement. ¾Weigh the implement separately. Since different equipment variants are possible, the weight of the implement must be determined by weighing. T L T V T H G H G V a b c d x Curb weight of tractor Front axle load of empty tractor Rear axle load of empty tractor Total weight of rear implement In case of towed machines: Maximum permissible drawbar load for road transport. Total weight of front implement Distance from centre of gravity of front implement (front ballast) to middle of front axle Tractor wheel base Distance from middle of rear axle to middle of tractor link arm ball In case of towed machines: Distance from middle of rear axle to middle of hitch-up point. Distance from middle of tractor link arm ball to centre of gravity of rear mounted implement (rear ballast) Concerning the centre of gravity see chapter "technical data"; if necessary pay attention to the correct choice of the centre of gravity. The following applies with towed machines: d = 0 Information of tractor manufacturer for minimum rear ballasting. If no information is available, enter All specified weight in (kg) All specified dimensions in (m) 22

41 Adjusting the drill unit DANGER Lowering machine parts can cause severe crushing accidents! ¾ Lock control units, if necessary. Make sure that the control units cannot be operated unauthorised. Instruct persons to leave the danger zone. ¾Comply with the accident prevention instructions. Drill shoes The seed shoes open the seed furrows and keep them clear for the placement of the seed. The drill shoes also keep the coulter discs and trap rollers free of dirt. ¾Check drill shoes regularly for function and wear. ¾ Adjust or replace the drill shoes if worn. d NOTE Adjust the individual components on all coulters all equally. a c b ¾ If the coulter disc is worn, move the drill shoes toward the top via the row of holes (a). The distance of the drill shoes to the edge of the coulter disc (b) should be approx mm Drill unit 1 Drilling arm bearing 2 Coulter disc 3 Drill shoe 4 Trap roller 5 Closing roller 6 Depth guiding wheel 7 Depth setting adjustment lever 8 Seed hose ¾ The drill shoes must have contact with the coulter disc over the entire length of the edge. If worn, open the screw (D) and adjust the seed shoes by adding spacer discs (c). The coulter disc should be rotatable by hand. 37

42 Trap rollers The trap rollers firm the seed in the seedbed and press it gently down. Closing rollers Depending on the field conditions, the required pressure may adjusted in different steps: Under moist conditions and sticky soils the trap rollers may pick up residues. In this case, the trap rollers should be directed up or disabled: 4 5 b 3 a 1 2 a ¾ Lift the trap roller until the side plate is located aligned with the hole (a). ¾ Fix the trap roller at this height with a screw. ¾ Let the lever on the torsion spring (a) engage in one of the three positions (1), (2) or (3). The pressure applied increases from position (1) to (3). The other end of the torsion spring can be adjusted, in addition, in the 2 positions (4) and (5). The pressure applied is thereby higher in position (5). ¾Relieve the lever for adjustment (a). ¾ Loosen the screw (b), dismantle and adjust position. ¾ Tighten the screw (b) and let the lever engage. Ensure the O-ring is seated correctly. 38

43 Angle of attack Depth guidance wheels In the basic setting the two markings on side panel and bearing journal are aligned: a b The depth guidance wheels shall rest against the coulter discs while they can still be turned easily by hand. The distance of the coulter disc can be adjusted by adding or removing shims. ¾ Disassemble the depth guidance wheel and add or remove shims (a). ¾ Attach the depth guidance wheel, tighten the screws. a The angle of attack can be adapted to the conditions of use. It can be changed by turning the bearing journal. ¾ Loosen the screw (a). Please note: The screws of the coulter on the right machine side have left-handed thread and are marked. The screws of the coulter on the left machine side have right-handed thread. ¾ Adjust the angle with the two-flats key (b) and tighten the screw. ¾ You should tend to set a larger angle of attack for heavy soil and direct drilling. (a) Shims Rubber mounting ¾ Keep the rubber mounting free of oil. Oils and grease can harm the rubber and thus adversely affect the function. 39

44 Depth setting The drilling depth, in addition to the basic setting of approx. 46 cm (on both coulter rows) is determined by the depth guidance rollers. The depth guidance rollers are mounted eccentrically to the coulter discs. By adjusting the lever (b) the position of the depth guidance rollers to the coulter body (c) and thereby the working depth is changed: c b a Support wheels (8 SD) The support wheels stabilise the seed bar and ensure uniform working depth over the entire working width. The support wheels must rest on the ground when the machine is unfolded and lowered to the working position. WARNING Risk of injury when adjusting the support wheels. ¾ Never reach into the holes! ¾Relieve the support wheel before the adjustment. (a) basic setting approx. 46 cm a ¾ Loosen the screw on the lever, slide the clamping piece up and adjust the depth guidance rollers with the lever. ¾ Slide the clamping piece down and tighten the screw. ¾Adjust all coulters equally. NOTE The correct settings must be adjusted to the respective conditions of use and can therefore be determined only during use in the field. ¾ Adjust the height of the support wheels on the row of holes and secure with a bolt (a). Secure the bolt with the cotter pin. ¾Adjust both support wheels the same. NOTE ¾ Adapt the height of the support wheels to the respective ground conditions. ¾ Check the drilling depth over the entire working width before starting work and, in case of larger fields, at regular intervals during work! 40

45 Use in the field ¾ Set the valve on the drawbar to thefield position: Coulter pressure The coulter pressure can be set via the valve next to the pressure gauge (at the right side of the machine). The coulter pressure can be increased through additional weights. a b Twin hopper: - Swivel the steps back and secure them. - Fold in the platform hydraulically. Please note: NOTE To control the seed refer to the operating instructions for the E-Manager The machine must be in horizontal position when used in the field. Do not drive backwards with the machine lowered. The components have only been designed for forward travel in the field and may be damaged when reversing. Pressure gauge (a) and coulter pressure valve (b) ¾ Changing the pressure on the setscrews. To make the adjustment, increase the pressure until the depth guidance rollers rest on the ground. ¾ Secure the setting nut with the locking nut. Headland ¾ Lift out the machine and move the coulter upward. ¾ After turning lower the coulter approx. 2-5 m in front of the seedbed with pressure at the appropriate fan speed. The seed requires some time to flow from the metering unit to the coulters. Working speed The speed depends on field conditions, soil type, harvest residues, seed, seed quantity and other factors. NOTE When drilling reduce the seed just before lifting out the machine. Otherwise the fan output would be excessively reduced and the hoses might get blocked. ¾ Operate somewhat slower under difficult conditions! 41

47 Checks The quality of drilling work essentially depends on settings and checks. ¾ Before starting sowing you should therefore carry out all maintenance and service work. ¾ Drilling must be checked when starting work and, in case of larger fields, also regularly in between! Machine ¾ Has the machine been hitched up correctly and are the coupling devices locked? ¾ Have the tractor link arms being locked against swinging sideways? ¾Have the hydraulic lines been correctly connected? ¾ Has the machine been levelled in working position and the drilling depth correctly adjusted? Metering unit ¾ Is the metering unit equipped with the correct cell wheel and is the sealing lip still in good working order? ¾ In case of small seed, has the cleaning brush been installed and is it in order? ¾ Is, especially in the case of small seed, the correct seed quantity being placed? ¾ In the case of large seed, has the scraper been installed? ¾ Are all connections, clearing valve and hopper tightly closed? ¾ Is seed coming out of all coulters? ¾ Is seed bridging forming in the hopper (particularly with husky seed)? Cultivation tools ¾Are coulters, other cultivation tools and optional equipment still in a serviceable state? ¾ Do the coulters have sufficient pretension and do they all rotate freely? ¾ Are the drill shoes still in good condition and correctly adjusted? Pneumatic system Fan ¾ Is the hydraulic fan connected to a pressure-free return flow? ¾ Are fan wheel and intake grille clean? ¾ Is the fan wheel tightly mounted on the shaft? ¾ Are fan speed and drive pressure not exceeded? 43

48 Pneumatic system The pneumatic system consists of Fan Hopper One or several metering units, depending on the design Distributor towers. WARNING Risk from hazardous dust (fertiliser, dressing). ¾ Always wear suitable protective clothing (safety goggles, respiratory masks, protective gloves) for cleaning and maintenance work. Fan The hydraulic fan is directly driven by the tractor hydraulics. The generated air flow conveys the seed from the fall sluices to the coulters. The required air quantity depends on seed (type and weight), seed quantity, working width and sowing speed. A correct fan speed cannot be specified and must therefore be determined by tests in the field. NOTE ¾ Fan setting, seed transportation and seed placement must be checked on all coulters when starting sowing, and also at regular intervals when working on large areas. NOTE ¾ Fan wing and protective grid must be regularly checked for dirt deposits and cleaned. Deposits on the protective grid restrict the air flow and thus lead to blockage in the seed pipes. Deposits on the fan impeller cause unbalance. The bearing will thereby be overloaded and can be damaged. To control the speed, the control unit in the tractor must be equipped with a flow control valve. Max. speed 4,500 rpm Please note: The air flow should not be too high, so that no seed or fertiliser will be blown out of the seed furrow. However, the air flow must also not be too weak, so that no seed or fertiliser will remain in the hoses and cause blockage. The fan speed should therefore be set as high as possible. Fan motor direct drive The fan speed is adjusted via the oil quantity on the flow control valve in the tractor. The hydraulic pump must deliver sufficient oil to prevent the fan speed from dropping, even when the tractor speed drops or other hydraulic functions are activated. 44

49 Connecting the hydraulics CAUTION Damages to the fan motor ¾ Be sure to connect the return line to the pressureless return of the tractor! ¾ Note the return flow pressure of max. 5 bar in the leak oil line! Retightening the fan flange The clamping taper fixates the fan wheel and additionally clamps on the drive shaft. The clamping taper on the fan drive may come loose. The impeller can thus move along the drive shaft and damage the fan. NOTE ¾ After approx. 50 hours retighten the clamping taper on the fan flange and check it annually. Pressureless return flow connection Checks and maintenance ¾ Maintenance work on the fan and opening of the protective grille only while the machine is at a standstill. Let the fan only run while the protective grille is mounted: Fan with protective grille ¾ Clean the protective grille at regular intervals to prevent a restriction in air flow and resulting blockage. ¾ Clean any dirt or deposits from the fan blades to prevent unbalance and damage to impeller and bearing. ¾ Retighten the clamping taper on the fan shaft (see chapter Retightening the fan flange). Clamping taper Please note: ¾ When tightening the screws, especially with a new assembly, the fan wheel will move towards the housing in the direction of the protective grid. ¾ A loose flange must therefore be aligned closer to the hydraulic motor. ¾ The clamping faces must be free of oil and grease. ¾ The clamping screws must be tightened uniformly and in several steps. Tightening onto the taper should be supported by light hammer blows on the flange (plastic hammer or hammer shaft). ¾ The inch screws in design No must only be tightened with a torque of max. 6.8 Nm. ¾ After tightening check the impeller for free and even running. 45

50 Hopper The hopper can be designed as single hopper for seed or twin hopper for the Grain & Fertiliser system (seed and fertiliser). Platform WARNING Risk of accident through hydraulic folding of the platform. ¾ Instruct persons to leave the danger zone. Make sure before movements of the machine that no persons are about on the platform. ¾ Secure control units against unintentional actuation. Single hopper The single hopper is closed with a covering. ¾ Always keep the covering closed to protect the seed against contamination, dust and moisture. In case of extreme development of dust, this dust can deposit in the hopper and fill up the roller flutes. This causes metering faults and unnecessary wear inside the metering unit. Twin hopper Various options for sowing are available with the twin hoppers: Same type of fruit in both hoppers Different types of fruit in both hoppers (selective hose assembly required, see chapter Optional equipment). Seed and fertiliser each in a separate hopper (Grain & Fertilizer) Both metering quantities are merged before the distributor tower and placed together. a b The twin hopper has a volume ratio of 40 : 60 (front : rear). It is designed as pressurized hopper and must always be closed and tightly sealed before placement. Leaks with a loss of air will cause sowing faults. The placing quantity will drop, possibly all the way down to zero. ¾ Unfold and lock the steps to access the platform (a) ¾ Twin hopper version: Unfold the platform hydraulically (b). CAUTION Risk of damage to the machine ¾ Fold the steps and platform before work in the field. ¾When folding the machine monitor the automatic folding of the platform before the wings fold. ¾ Check the hoppers for leaktightness after each opening and after extended idle times while the fan is running. Switch on the fan and feel with your hands around the lid and listen for escaping air. ¾ In case of leaks replace the seals or readjust hinges and locks. ¾ Open the hoppers only after the internal pressure in the hopper has been relieved. 46

51 If twin hoppers are used to transport fertiliser over longer or bumpy distances, the fertiliser may solidify inside the hopper. This may cause heavy starting of the metering unit coupled with the risk of seed bridging in the hopper. d e f ¾ Restore the pouring capability of the fertiliser in this case before placing. Seed hopper The fan air flow is divided before the metering units (a). The metering units transport the seed via the dual fall sluice into both hoses (b). Twin hopper version: The lever position shown applies to both levers in each case. ¾ Adjust both levers centred: b a ¾ Use only symmetric cell rotors in both metering units. c ¾ Selective hose routing: Adjust the levers in opposite direction (twin hopper only): Mechanical version Half-width shut-off is adjusted via the valves (c). Lever (d) adjusts the valve (e) so that seed/ fertiliser is each introduced into the air flow on the side opposite the lever (f): Electrical design The valve is adjusted with the positioning motors on the metering units: 47

52 Mechanical half-width shut-off The side to be shut off is allocated to a distributor tower. No seed or fertiliser may flow through the hose leading to this distributor tower. ¾ Place both levers in the direction of the respective hose: The levers must point to the hose leading to the distributor tower the hoses of which run to those coulters on the side to be shut off. Tram line with half-width shut-off If a tram line is required with section shut down enabled, one must consider the installation position of the valves. Hoses may need to be replugged or the control adapted. Seed flow monitoring with half-width shut-off If the switched off section is equipped with sensors for seed flow monitoring, these would indicate corresponding alarm messages in the terminal. You can either switch off the seed flow monitoring, or unplug the sensors and correct their number in the machine configuration. The seed and fertiliser quantity must be halved in the terminal. Both metering quantities can be reduced, for example, to 50% via the %-adjustment button. Please make sure that both metering units are switched ON on the page Machine data under Delta Step. Half of the desired quantities can also be entered for both metering units in kg/ha. In both cases the drilled area is counted over the entire machine width. If the correct display of the drilled area is required, the working width must be divided in half in the machine configuration. The seed and fertiliser quantity must in this case not be manually changed. 48

53 Electric half-width shut-off The valve is adjusted with the positioning motors on the metering units. In the terminal both motors are controlled in parallel mode by the half-width shut-off. Tram line with half-width shut-off If a tram line is required with section shut down enabled, one must consider the installation position of the valves. Hoses may need to be replugged or the control adapted. Seed flow monitoring with half-width shut-off If the switched off section is equipped with sensors for seed flow monitoring, these would indicate corresponding alarm messages in the terminal. You can either switch off the seed flow monitoring, or unplug the sensors and correct their number in the machine configuration. ¾ Switch off the desired section in the terminal. Both valves will be adjusted - the display flashes. ¾The seed and fertiliser quantity is halved. ¾ For the drilled area counter the working width is automatically halved. ¾ Once the two valves are in right or left switching position, the switched off half width disappears from the display. NOTE ¾ Check the function of the half-width shut-off during field use. The positioning motors must each be in their end position. Seed flow monitoring Seed flow monitoring is automatically switched off. Please note: The sensor numbers can also be entered into the tram line list. In this case this list would also need to be updated. 49

54 Metering unit Rotors The HORSCH metering unit consists of only a few individual parts and can be dismantled without tools A large number of rollers is available for the different seed types with numerous geometrical shapes and grain sizes, as well as fertilisers in form of powders or granulates. Rollers with special properties are also available for fertiliser, fine and coarse seeds. The selection of individual rollers for various applications, working widths and delivery volumes is described in the E-Manager instructions. The cell rollers are arranged according to their delivery rate per revolution. Rollers for double fall sluices Metering unit 1 Housing 2 Drive motor 3 Clearing valve with sealing lip 4 Roller 5 Side cover with roller bearing 6 Side cover for pressure hopper with scraper plate 7 Side cover for normal hopper with rape brushes CAUTION Risk of crushing on the metering unit ¾ Do not reach into the rotating metering unit. ¾ Whenever performing assembly work on the motor mount it with the bore facing down to prevent water from entering the housing. On machines with double fall sluice and two seed boxes a roller design with symmetric graduation must be used when using a split roller. Otherwise the seed is unevenly distributed to the two halves. NOTE Ensure absolute leak tightness of components with all work activities on the metering unit. Leaks lead to metering errors. The contact surfaces must be sealed when installing the metering unit. The housing must not be warped when bolting it. The bottom of the metering unit is completed by the fall sluice. In the fall sluice the seed is picked up by the air flow. During calibration the seed is taken out of the metering unit through the opening in the fall sluice. The covering must subsequently be closed again tightly. 50

55 Roller change After choosing a rotor from the table it must be installed in the metering unit. ¾ Empty the seed hopper, if possible, before changing the roller. ¾Unscrew the side cover. ¾ Pull out the roller with the drive shaft. Roller change with gate valve Changing the roller while the hopper is full is easier if a gate valve is provided above the metering unit. ¾ Pull out the gate valve (1). 1 2 Gate valve pulled out Rotor change ¾Remove lock washer and washer. ¾ Pull out the drive shaft and assemble the new roller. ¾Change the roller as described in Roller change. ¾ Push in the gate valve and let it engage (2). The drive shaft requires axial clearance in the roller for self-cleaning of the roller in the metering housing. Changing the rotor The setting of sealing lip and the concentricity of the roller must be checked after each roller change. 51

56 Roller change at full hopper without gate valve Adjusting the sealing lip NOTE A defective sealing lip or incorrectly assembled supporting plate cause metering errors during sowing. Rotor change with full hopper ¾ Unscrew wing screws on side cover and drive motor. Remove side cover and motor. ¾ Remove lock washer and washer from the drive shaft. ¾ Plug the new cell roller on the drive shaft and use it to push the old roller out of the motor side. ¾ Fix the drive shaft, assemble and fasten side cover and motor. ¾ The sealing lip must not be torn or damaged. Replace the sealing lip at least 1 x per year. ¾ Insert the side cover with the sealing lip into the metering housing. The sealing lip must have full contact with the rotor and should be able to generate approx. 1 mm pre-tension. approx. 1 mm Sealing lip The retaining plate for the sealing lip is asymmetrically divided. With all normal and fine seeds the wider side must face towards the roller. In case of faults with coarse seeds such as maize, beans etc. both the retaining plate and the sealing lip can be replaced by a wider design. ¾ Take out the roller. ¾ Insert the side cover with the new sealing lip. Tighten the sealing lip only far enough to still allow it to slide. ¾ Move the lip so that it projects approx. 1 mm into the roller recess. ¾ Remove the side cover. Do not move the lip anymore and tighten it. ¾ Assemble the side cover, check the setting once again and reinstall the rotor. 52

57 Rotors for fine seeds The rollers for fine seeds consist of cell discs, spacers and drive shaft. In order to avoid malfunction when sowing fine seed, the cell rollers are completely preassembled at the factory. The rollers can be assembled with one or two cell discs. The use of two cell discs on the roller doubles the delivery rate. Cell discs are available with displacements of 3.5 cm³, 5 cm³, 10 cm³ and 25 cm³. Only the cell discs in the roller turn while sowing. The spacers are blocked by stop positions on the housing. NOTE On machines with double fall sluice and 2 seed boxes you may only use rollers with 2 cell discs. Otherwise the seed is unevenly distributed to the two halves. Removing or installing a fine seed roller The anti-rotation locks must be turned towards the recess in the housing in order to install and remove the rollers. Roller assembly for fine seeds Maintenance The function and operability of fine seed rollers must be checked every day. ¾ There should be no gap between the cell discs. If the gap is too big, additional shims must be added. ¾ The cell discs must be light turning. Dressing or similar materials must not block cell discs or bearings. ¾ The safety clips must be in place and correctly assembled to avoid the formation of a gap. Assembly note To prevent seed from entering between cell discs and spacers the cell discs and spacers are installed with zero clearance shims. Roller for fine seeds 53

58 The spacers are equipped with bearings. Depending on the manufacturing tolerance shims are added to avoid any friction between cell discs and spacers. After the assembly of all parts the remaining gap to the lock washer is filled up with shims. Finally assemble the lock washer. Rape brushes The rape brushes clean the cell discs in the rollers for fine seeds. Before sowing fine seeds the rape brushes must be installed in the side cover and their function must be checked. With the roller correctly assembled the cell discs between the spacers can just be freely turned. The parts must not rub against each other. The clearance should therefore be as little as possible. When checking against a light source the gap should just be visible. Function test After installing the new roller the function and concentricity of the new roller must be checked. For this purpose switch on the roller as described in the section Calibration test. ¾ The drive motor must run smoothly. No stiff points should be recognizable. ¾ Check the motor for smooth running. Untrue running causes inaccurate metering and may overload the motor. ¾Locate any stiff points, if possible. ¾ Rework damaged parts (by machining...) or replace. ¾ Loosen the screws on the side covers for drive motor and roller bearing and realign the side covers to release tension. ¾ If the drive shaft has been bent, realign or replace it. ¾ Remove any foreign bodies that may have been jammed between roller and housing. ¾ If dust or dressing in the roller has entered between cell discs and spacers dismantle and clean the roller. Rape brushes assembled ¾Check concentricity and fastening. ¾ Check condition and cleaning effect of brushes. ¾ Install the side cover with the brushes into the metering unit. ¾ The brushes must firmly rest against the cell discs and rotate with the roller. NOTE The function and cleaning effect of the rape brushes must be checked before starting sowing and at regular intervals during work. Sticking cell discs cause metering errors during sowing. Less seed is placed. The side cover with the rape brushes can be removed even when the seed hopper is full. Sticking cell discs can then also be cleaned in assembled condition. The rape brushes should be disassembled when sowing normal seeds. The housing holes must be closed. 54

59 Coarse seeds For sowing coarse seed (maize, beans, peas, etc.) the metering unit must be converted. ¾ A deflector must be installed instead of the rape brushes. This deflector prevents large seed grains from getting caught between roller and housing, being damaged or blocking the roller. ¾ If necessary, mix talc or graphite powder with the seed. Large seed grains partly have poor trickling characteristics and thus do not fill the roller flutes completely. ¾ When using the adapter frame you must install and adjust a wider sealing lip - see adjusting the sealing lip. ¾ The special rollers for coarse seeds should be used in this case. These are available in different sizes to match the different working widths and seed quantities. Deflector ¾ For very large grains an adapter frame may be installed. For large grains this eases the entry into the metering unit and prevents grains from being damaged. Option, see spare parts catalogue 55

60 Metering unit with injector fall sluice The metering units in machines with normal hopper and injector fall sluice are equipped with a lid (V2A) with machined recesses. During operation the injector nozzle is exposed to vacuum. This lid adds additional air to the air flow. Maintenance of the metering unit The metering unit does not require any special maintenance. In order to avoid repair related downtimes, both the metering unit and the drive motor should be cleaned and subjected to a function test after the end of the season. The bearings in the side cover in particular can be damaged or may become hard-moving because of dressing dust. If necessary keep bearings in stock and replace in due time. 1 Metering unit with lid for injector nozzle The adjustment between injector nozzle and lid works up to a max. possible seed quantity. Exceeding this quantity results in a dynamic pressure at the injector nozzle. This may blow seed out through the perforated plate, which leads to a strip-like emerging of the seeds. These grains are visible on the surface of the field before they are covered by the packer or the harrow. Under extreme conditions overpressure can block the seed flow in the hopper. This causes seed failure. NOTE Always check the function of the pneumatic system and the seed placement but especially at high placing quantities and working speeds. No grains should remain on the surface of the field. If grains are blown out, the fan speed needs to be increased (temporarily up to 4000 rpm) or the working speed must be reduced until the injector system works correctly again.

61 Calibration CAUTION Risk of crushing on the metering unit ¾ Do not reach into the rotating metering unit. NOTE ¾ Calibrate the machine only when lowered and parked securely. ¾ Do not use sticky dressings with seed. They influence metering accuracy. ¾Check seed and hopper for foreign objects! ¾ Depending on the seed install the rape brushes or, for coarse seeds, the adapter frame, the deflector and the wide sealing lip. For grain and fertiliser disassemble the accessory parts. Check all side covers on the metering unit. ¾ Install the appropriate roller for the seed/ fertiliser quantity and check for true running. ¾ Check condition and correct setting of sealing lip. ¾ Fill the hopper with seed / fertiliser. Only fill in small amounts of fine seeds. ¾ Open the valve or covering under the metering units (1) ¾ Check and clear the fall sluice and the pipes of any dirt and seed deposits. Attach the calibration bag or slide it in along the rails (2). ¾ Calibrate the machine (see E-Manager instructions). ¾Close the flap / covering. Ensure air tightness! ¾ Twin hopper: Perform calibration for both metering units. Distributor Two distributor towers are installed at the rear of the seed tank for seed or fertiliser distribution. NOTE All distributor components must be leak tight. Even slightest leaks and air losses will cause uneven distribution. 2 1 Distributor tower 1 Seed flow sensors 2 Tram line valves Valves for tram line control 1 The distributor is equipped with valves for the tram line control. The arrangement depends on the working width, the tram line rhythm, the track width of the spraying and spreading machine and the number of valves per track. 2 The valve function can be checked by examining the air flow on the seed coulters or the seed placement on the surface. 57

62 The valves have a small identification mark on the underside of the shaft, which shows the position of the valves. This enables checking the rotary motion of the valve and its end position. Marking of tram line valve (position open) If the tram line distribution box is equipped with a track width change-over, the track width must only be changed when the valves are open. This can be checked on the terminal (no tram line must be switched) or by checking the marks on the valves. Seed flow monitoring The seed flow sensors enable the monitoring of up to 120 seed and fertiliser hoses. The sensors are connected in series and the numbers inform about the order. In cases of an alarm, these sensor numbers help when troubleshooting the hoses. If the monitored seed hoses are also fitted with valves for the tram line control, these numbers must also be entered in a list in the terminal menu for tram line rhythm - see E-Manager instructions. 58

64 Parking brake The machine always needs to be secured with the parking brake to prevent the drill from rolling away in case of pressure loss in the service brake. ¾ For this purpose pull the parking brake button down. Maintenance ¾ Drain the air reservoir every day during operation. The parking brake works with spring brake cylinders. With the air reservoirs fully filled the brake can also be released manually and the seed wagon can be moved without braking function. NOTE However, the machine must be hitched up beforehand or secured against rolling by other suitable means. Driving without brake on public roads is prohibited. Releasing the brake ¾ Press the parking brake button to release the parking brake. NOTE ¾ Before parking the machine pull the parking brake button down again to apply the parking brake. Air vessel with drain valve ¾ Clean the pipe filter on the coupling as required but at least once a year. ¾ Check the brake lining for wear every year and renew as required. ¾ To ensure the function of the valves, antifreeze should be mixed into the compressed air. Follow the operating instructions of the tractor! ¾ The coupling heads should be closed with blind covers or a plastic bag to protect against damage caused by moisture. ¾ Release the brake. Brake pads may otherwise stick to the drum and make restarting of the machine more difficult. Emergency releasing facility In events of emergency the spring brake cylinders can also be released manually. For this purpose back out the screw under the blue covering on the housing until the brake is released. 60

65 Hydraulic brake The hydraulic line controls the brake power to the brake cylinders. The brake inlet pressure must not exceed 130 bar. Connection 1. When hitching up connect the hydraulic brake line with the brake line on the tractor. 2. Fasten the break-away protection cable at a suitable place on the tractor. WARNING The cable may be caught by other machine parts and thus trigger flat-out braking when cornering. Danger of traffic accidents! ¾ Fasten the cable in such a way, that it cannot be caught in any place. 3. Release the parking brake. The ropes must be relieved and the wheels must be free to rotate. WARNING Danger of traffic accidents caused by brake failure! During commissioning or after long periods of rest: ¾ Fill the pressure accumulator for emergency braking before starting to drive. ¾ Fully kick down the brake pedal on the tractor for this purpose. With each actuation of the brake, the pressure accumulator is pressurized, if required. Unhitching 1. Park the machine. 2. Apply the parking brake. 3. Place wheel chocks under the wheels. 4. Loosen the brake line. 5. Disconnect the break-away cable from the tractor. 6. Unhitch the machine. Unhitching does not trigger the breakaway brake.

Parking brake with crank handle ¾ Always apply the parking brake and secure the machine against rolling away before parking the machine. ¾ Always release the parking brake before longer periods of rest or at the end of the season. Brake pads may otherwise stick to the drum and make restarting of the machine more difficult. ¾ Always release the parking brake before transport travels. The ropes must be relieved and the wheels must be free to rotate. Maintenance ¾ Check the function of the parking brake before connecting the machine. ¾ Where necessary adjust the cable or the brake pads. 62

67 Micro-granulate facility For machines with twin hopper granulate (e.g. pesticide, fertiliser) fine grains can be placed in addition with the micro-granulate facility. The maximum possible placing quantity is 30 kg/ ha at 10 km/h working speed. Micro-granulate is transported to the metering screw. The required quantity is transported via the screw and fed to the fan air flow NOTE The granulate must be more of a granular composition. The metering unit is not suitable for sand or dust like substances The micro-granulate is stored in a tank (200 l) inside the hopper. Micro-granulate metering ¾Unlock to open (a) and turn counterclockwise (b). ¾ Turn clockwise to close (c) and lock (a). 1 Metering housing / feed 2 Metering screw 3 Hopper empty sensor 4 Gate valve b 5 Pressure compensation hoses 6 Calibration bag mounting 7 Metering motor 8 Introduction into fan air flow Adjustment and operation a Open / close tank (twin hopper version) The tank must be absolutely leaktight during use! ¾ Always check the cover for leak tightness with the fan running, after it had been opened. c CAUTION Risk of injury on the rotating screw ¾ Switch off the micro-granulate facility before working on the metering screw. Depending on the granulate quantity, the metering unit can be fitted with two different augers. The theoretical displacement of the augers is 38 cm³ or 66 cm³ per revolution. The actual displacement depends on various factors and can therefore only be determined by calibration. 63

68 NOTE ¾ For fine seeds use only the chamfered metering screws. For reasons of differentiation these metering screws are marked with an R preceding the size. Seed calibration The calibration sequence and the input on the terminal is identical with the calibration for seed/ fertiliser. NOTE ¾ Perform calibration with the left metering screw viewed in travel direction. Metering screws for fine seeds Changing the metering screws ¾ If the hopper is full, loosen the gate valve with the wing nut and reinsert it into the slot the other way around (1). ¾ Loosen the two wing nuts on the metering unit and pull out the lid with the metering screw (2). ¾ Pull the spring pin out of the shaft (3). ¾ Replace the screw. Pay attention to the condition and the correct fit of the O-ring on the screw to be assembled. ¾ Insert the spring pin. ¾ Reinsert the parts into the metering unit. ¾ Turn the screw further until the hexagon can be inserted into the drive from the top. ¾Retighten the wing nuts ¾ Remove the rear hose and attach the calibration bag (4). ¾ For low granulate quantities install the 38 cm³ screw. For high quantities or high working speed install the 66 cm³ screw. ¾Fill the hopper with granulate. ¾ Run the metering screw for a moment so that it is completely filled and the calibration will not be falsified (see E-Manager - filling the metering cells). ¾ Run the calibration and enter the calibration weight (see E-Manager instructions). ¾ If the matching speed range is displayed after entering the weight, you may start drilling. ¾ If the indicated speed range is not suitable for drilling, you may have to exchange the metering screw and repeat the calibration process. Initial use The metering units must first run in during initial use. NOTE ¾ During initial use repeat calibration after one hour running. 64

69 Selective hose assembly Hose assembly can be selective. In this case, the hoses of a distributor tower are allocated to a coulter row: Left distributor tower Ø front coulter row Right distributor tower Ø rear coulter row Ø See appendix Selective hose assembly allows sowing different types of fruit in alternating rows. Half-width shut-off is not possible in this configuration. Additional weights To increase the coulter pressure additional weights can be inserted in the area of the undercarriage and the drawbar: Setting the bout markers WARNING Risk of injury from the bout marker. Order persons to leave the slewing range of the bout markers. When installing for the first time, the bout markers must be set to working width. Marking takes place in relation to the centre of the tractor. The adjustment length of the bout markers (measured from the middle of the outermost row) results from half the working width plus half the row spacing.

71 Care and maintenance CAUTION Please observe the safety notes on care and maintenance! Your machine has been designed and built to offer maximum performance, economy and operator friendliness under a vast variety of operating conditions. Before delivery the machine was examined in the factory and by your dealer to make sure that it is in optimal condition. For trouble free operation it is very important to carry out the necessary work for care and maintenance in the recommended intervals. Cleaning Maintenance intervals The maintenance intervals are determined by many different factors. For example, the different operating conditions, weather impact, travel and working speeds, dust accumulation and type of soil, seed, fertiliser and dressing used, etc. affect the maintenance intervals. The quality of the lubricants and cleaning agents also affects the time to the next care work. The specified maintenance intervals therefore only serve as a reference. In case of deviations from normal operating conditions the intervals must be adapted accordingly. Regular maintenance is the basis for a fully operable machine. Properly serviced machines reduce the risk of failing and ensure economical use and operation of the machines. Clean the machine thoroughly at regular intervals and after the end of the season. NOTE Do not clean electrical components and fan or hydraulic cylinders and bearings with a high pressure cleaner or direct water jet. Housings, screw fittings and bearings are not water proof under high pressure. ¾ Clean the outside of the machine with water. Open the fall sluice under the metering unit, so that entered water can flow off. ¾ Clean the cell wheel inside the metering unit with a brush and compressed air. ¾ Blow out coulters, seed lines, seed hopper, metering unit and fan with compressed air. ¾ When using fertiliser clean and rinse the components thoroughly. Fertilisers are highly aggressive and can cause corrosion. 67

72 Storage If the machine is to be shut down for a longer period of time: ¾ If possible store the machine under a roof. ¾ Completely empty and clean the seed and fertiliser hopper. ¾ Reduce the coulter pressure adjustment to relieve the rubber elements. ¾ Open the clearing valve. ¾ Unplug the terminal and store it in a dry place. ¾ Protect the machine against corrosion. For spray coating use only biodegradable oils. ¾ Take all load off the wheels. ¾ Protect the hydraulic cylinder piston rods against corrosion. NOTE Lubricating the machine The machine should be lubricated at regular intervals and after washing with a pressure cleaner. This ensures operability and reduces repair costs and downtimes. Hygiene Lubricants and mineral oil products are no threat to health, as long as they are used as instructed. Avoid prolonged skin contact or the inhalation of vapours. Handling lubricants Use gloves and skin protection creams to protect against lubricants. Avoid direct contact, use soap and water if contaminated. Do not spray the plastic and rubber parts with oil or corrosion protection agent. These parts would become brittle and break. 68
