Unrestricted field of vision to the rear After it has been coupled, ensure that you have an unrestricted view of the machine, in both its work and transport positions. Otherwise, dangerous situations may not be detected in time, resulting in accidents or damage. 18

19 \ Coupling Safety Increased risk of injury While hitching the implement to the tractor, there is an increased risk of injury. Therefore ensure that: the link-up is carried out on a flat, even and stable surface secure the tractor so that it cannot move (handbrake on, wheels chocked) the tractor and implement belong to the same category of machinery during the hitching, you do not stand between the tractor and the implement you activate the 3-point hydraulic lift slowly and with great care Failure to observe these precautions could lead to serious injury or death. Only make the electrical connections after assembly is complete While the any electrical equipment is being fitted, the power source must not be connected to the tractor. This could cause short circuits and damage to the electronic parts. Only connect the hydraulic components when they are not pressurized Only connect the hydraulic hoses to the tractor's hydraulic system if neither hydraulic system (tractor and implement) is pressurized. A pressurized hydraulic system can cause the implement to move unexpectedly. High pressure inside the hydraulic system The interior of the hydraulic system is highly pressurized. Check for any leaks or external damage to the cables, hoses and screw attachments on a regular basis. When checking for leaks, only use a suitable product. Do not check for leaks by feeling with hands or any other body parts. Repair any damage immediately. Oil leaks can cause serious injury and burns. In the case of injury, seek medical attention immediately. Replace hydraulic hoses every six years or earlier Hydraulic hoses age without showing externally visible signs. Replace hydraulic hoses every six years, or earlier if aging or degradation is visible. Defective hydraulic lines can cause serious or fatal injuries. Colored markings on hydraulic hoses In order to prevent malfunctions, mark the hydraulic connection sleeves and coupling pins between the tractor and implement with different colors. Incorrect connection of the hydraulic hoses can cause the implement to make unpredictable movements. Drive shafts Before connecting or disconnecting a transmission shaft, disengage the PTO, switch off the engine and remove the ignition key. Observe the operator s manual of the PTO shaft manufacturer Observe the operator s manual of the PTO shaft manufacturer. It will provide you with instructions on how to handle the PTO shaft correctly. If these instructions are ignored, damage may be caused to the PTO shaft and machine. 19

20 Safety Distance of center of gravity \ Observe recommendations for the gross weight, the axle loads, the tire load capacity and the minimum counterweights Front or rear attachment of implements must not cause the permitted gross weight, axle loads or tire load capacity of the tractor to be exceeded. In order to maintain a safe turning capacity, the front axle must carry at least 20% of the unladen weight of the tractor. Using a few simple calculations, it is possible to determine: gross weight axle loads tire load capacity and minimum counterweights (B) load on front axle (A) unladen weight (C) load on rear axle For these calculations, the following data is required: (A) unladen weight (B) load on front axle (C) load on rear axle consider also, for example: weight of water in the tires, of attachments and similar. (E) gross weight with front attachment (D) gross weight with rear attachment (D) gross weight of the implement with rear attachment. With towed implements, take the support load into consideration (E) gross weight of implement with front attachment (F) distance from center of gravity of implement to the center of front axle (forward mounting) (F) distance: from center of gravity of the implement to the center of the front axle (forward mounting) (G) distance: from the center of the lower attachment bearings to the center of gravity of the implement (rear mounting) (G) distance from center of lower attachment bearings to center of gravity of implement (rear mounting). With towed implements G=0 Data obtained from measurements: (H) tractor wheelbase (I) Distance from center of rear axle to center of lower attachment bearings (H) wheelbase (I) distance: from the center of the rear axle to the center of the lower attachment bearings 20

21 \ Safety Calculation Counterweight with front weights The values taken from measurements can now be used to calculate formulas. Calculation of counterweight with front weights for implements with rear attachment. Front counterweight in kg (lbs) = D I+ G B H 0, 2 A H F + H Counterweight with rear weights Calculation of counterweight with rear weights for implements with front attachment. Rear counterweight in kg (lbs) = E F, C H 0 45 A H H + I+ G Front axle load Calculation of the effective load on the front axle Front axle load in kg (lbs) = E F H B H D I G H gross weight Calculation of the effective gross weight + + Gross weight = E A D Rear axle load Calculation of effective load on rear axle Rear axle load in kg (lbs) = effective gross weight - effective load on front axle Tire load capacity Data relating to front and rear tire load capacity can be found in the documentation supplied by the tire manufacturer. Where there are two wheels present, the front tire load capacity is found by multiplying the permitted load capacity of one front tire by two. Where there are two wheels present, the rear tire load capacity is found by multiplying the permitted load capacity of one rear tire by two. Assessment Ensure that the following conditions are met: the effective rear axle load values must be less than the permitted values specified in the tractor operator s manual. the tire load capacity must be greater than the rear axle load values specified in the operator s manual. the effective gross weight must be less than the permitted gross weight specified in the tractor operator s manual. If these conditions are not met, the implement must not be attached to the tractor. If there is a weighing machine of sufficient dimensions available, the gross weight and the rear axle load can be measured by weighing. 21

22 Safety Example \ Calculation of counterweight with front weights for implements with rear attachment. D = 2100 kg ( lbs) I = 1180 mm ( in) G = 650 mm(25.59 in) B = 2520 kg ( lbs) H = 2720 mm( in) A = 6300 kg (13889 lbs) F = 1367 mm(53.82 in) kg= 2100x( )-(2520x2720)+(0.2x6300x2720) = lbs= x( )-(5555.6x )+(0.2x13889x ) =

23 \ Road transport Safety Ensure that the vehicle configuration meets the requirements of the highway code If it is necessary to travel on public roads with the implement, it must comply with current traffic regulations. For example: installation of lighting, signalling and protection devices, compliance with width/weight transport limits, and permitted axle load, tire load capacity and gross weight limits, the maximum permissible road transport speed must be complied with, but not exceed 40 km/h (25 mph), the steering capacity of the tractor must not be limited, the steering axle must be loaded with sufficient weight, the machine should only be towed by agricultural or forestry tractors, implement is centered for transport. The driver and owner of the vehicle are responsible for any failure to comply with traffic regulations. Close the ball valves If the hydraulic hoses or hydraulic cylinders are equipped with ball valves, these must be closed when driving on the road, in order to avoid accidental activation of the tractor distributors which could cause the implement to move. This could result in damage to the implement or accidents. Immobilizing moving parts During carriage and transit, always use the transportation safety devices on all the moving parts, accessories and equipment which require their use. If the implement is equipped with quick-release couplings, check the rope All remote controls (ropes, electric cables, hoses, etc.) must be positioned so that they cannot accidentally activate the corresponding devices. In particular, the ropes must hang freely and must not under any circumstances provoke the automatic activation of the quickrelease coupling. Otherwise, the implement could release itself from the 3-point hitch. Be aware of effects on driving and braking Driving with the implement will affect driving and braking characteristics. Be especially careful on corners, and keep in mind the increased width and/or overall mass of the implement. Inappropriate conduct on the road can cause accidents. Proceed at a suitable speed Always adapt driving speed to the conditions of the road surface. Driving on unfavourable road surfaces or driving too fast can lead to the development of powerful forces which overload the tractor and the implement. Driving at an inappropriate speed can cause accidents or damage to the implement. Accident with serious or fatal injures may be causes as a result. Check hitch pins Hitch pins must be in perfect condition. Hitch pins must show no signs of wear and be properly secured. Otherwise, hitched machines may detach themselves of their own accord. Accidents with serious or fatal injuries may be caused as a result. 23

24 Safety Operating the implement \ The implement may only be put into operation after training The implement may be used for the first time only after the user has read and understood the operator s manual and completed training under the guidance of the retailer, representative or manufacturer. Using the implement without appropriate training could cause damage to the implement, due to misuse, or accidents. Ensure technical conditions are perfect Only begin using the implement if it is in perfect technical condition. Before use, check all the most important components and replace any that are faulty. Faulty components can cause damage to property and persons. Do not remove any protective equipment Protective equipment and guards must not be removed or changed. Before use, check all protective equipment. If not equipped with protective gear, parts of the implement can cause serious injury or death. Height of the implement and overhead power lines Keep a safe distance from live overhead power lines during any operation involving the implement. This carries a risk of electric shocks. In the case of contact between the implement and a live overhead power line: do not leave the tractor cabin do not touch any metal parts of the tractor do not create a connection with the ground warn persons not to approach the tractor or implement await the arrival of qualified rescue personnel; the overhead power line will need to be switched off. Never climb on the implement when beneath live overhead power lines. The current could be transmitted even without direct contact. Check the danger zone The danger zone around the implement is 70 m (230 ft). Check the danger zone around the implement before driving off and continually during operation. Make sure that you have an adequate view. Only start up and operate the implement if there are no people, animals or objects in the danger zone. In unfavourable circumstances, objects may be thrown from the implement at high speed. Failure to respect these conditions when using the implement could lead to serious injury or death. Tighten screws and bolts Tighten screws and bolts regularly, and if necessary check they are in the correct position. With use screws can become loose, though not obviously so. Check also that the hydraulic fittings are correctly tightened. Failure to do so could result in damage to the implement or accidents. In case of malfunction In the case of malfunction, stop work immediately and halt the implement. Resolve the problem immediately or contact an authorized workshop. Continued use could lead to damage to the implement or cause accidents. 24

25 \ Safety Cornering and turning manoeuvres Centrifugal forces are in operation during cornering. The machine's center of gravity at the rear of the tractor is displaced. Be aware of the turning radius and the moment of inertia. A driving style which is not adapted to conditions can cause accidents. Accidents with serious or fatal injuries may be caused as a result. The rotor continues turning after the PTO has been switched off After the PTO shaft drive on the tractor has been switched off, the machine continues to run due to the moment of inertia. Maintain a sufficient safety distance until all moving parts have come to a complete standstill. Otherwise, damage to the machine and serious or fatal injury may be caused as a result. 25

26 Safety Uncoupling \ Increased risk of injury Disassembling the implement from the tractor carries an increased risk of injury. Therefore ensure that: all moving parts are complete standstill, the detachment is carried out on a flat, even and stable surface, the tractor is secured so that it cannot move, the foot of the implement is lowered and adjusted to ensure correct support on the ground, during disassembly, you do not stand between the tractor and the implement, you activate the 3-point hydraulic lift slowly and with great care, shut off the engine and remove the ignition key before disconnect the PTO driveline and hose connections, only disengage the hydraulic hoses if the hydraulic system (of the tractor and implement) is not pressurized, place the PTO shaft in the holder provided, disconnect all electrical connection if present. Failure to observe these precautions could lead to serious injury or death. Care and maintenance Observe care and maintenance intervals Respect the recommended intervals for checks and inspection as specified in the operator s manual. Failure to observe these intervals could lead to damage to the implement, inferior performance or accidents. Only use genuine spare parts Many components have special characteristics which are essential to the stability and function of the implement. Only the accessories and spare parts provided by the manufacturer are checked and approved. Other products could impact negatively on the function and safety of the implement. Use of non-genuine spare parts renders the warranty and manufacturer's liability void. In addition, any modification of the implement and its accessories will render the warranty void. Before commencing any maintenance work: switch off the PTO shaft drive Warning: moving rotor After switching off the PTO shaft drive, the rotor on the implement will continue to rotate for a few seconds due to inertial force. Wait until all parts have stopped moving completely. Otherwise, damage to the machine and serious or fatal injury may be caused as a result. switch off the hydraulic system pressure, whenever possible, uncouple the tractor. place all controls in neutral or park, set tractor parking brake. secure the tractor using wheel chocks so that it cannot move, switch off the tractor and remove the ignition key. ensure that the implement is safely positioned on a flat, even and stable surface, lower and adjust the foot to ensure correct support on the ground and if necessary use additional fastenings, 26

27 \ Safety do not climb on any part of the implement; use a suitable ladder, Safety during care and maintenance work can only be guaranteed when all of these precautions are taken. Interrupting the power supply Before handling the electrical system, disconnect the power supply. Live systems can cause damage to property and persons. Replacing hydraulic hoses It is recommended that hydraulic hoses be replaced every six years. Even if they are not visibly damaged, hydraulic hoses wear out over time. Damaged hydraulic hoses can cause serious injury or death. Take care when cleaning with high pressure water jet washers The implement can be cleaned with water or steam. When cleaning in proximity to certain components, for example bearings, electrical parts, distributors, plastic parts, hydraulic hoses and other areas of the implement where penetration could damage equipment, use only low pressure. Pressure that is too high could damage these parts. No aggressive washing additives Do not use any aggressive washing additives for cleaning. Uncoated metal surfaces can be damaged. Welding operations It is forbidden to carry out any welding on the implement. Tightening screw connections Once maintenance work is complete, re-tighten all screw connections that were previously unscrewed. Failure to tighten screw connections can lead to gradual loosening of the screws and subsequent detachment of parts from the implement. This could lead to serious injury or damage to property. See page 54 for proper torque values. Further regulations Personal protective equipment (PPE) Warranty Observe the regulations In addition to these warnings, you must also observe: accident prevention measures, universally-recognised rules regarding technical safety, occupational health and the highway code, the warnings contained in this operator s manual, the prescribed instructions for use, maintenance and repair.

36 Hitching the implement Rear hitching quick-release attachment bearing locking pin washer and lynch pin locking pin Line up the tractor with the implement, balanced on the ground in a stable manner, mount the tractor's lower attachment bearings on the lower locking pins of the implement and secure with lynch pins, interposing the washers, fit the bearing of the tractor's top link tie rod onto the locking pin of the upper attachment of the implement, insert the washer and secure with the lynch pin, fasten the lower hoist arms, adjusted to the same height, to the implement's corresponding lower attachments, washers and lynch pins The attachment is easier if the lateral stabilizers of the tractor's lift arms can move freely. On completion of the hitching operation, the stabilizers should be adjusted so as to limit oscillation (during machine transport, all oscillation must be completely eliminated). fit the end of the tractor's top link tie rod into the implement's upper attachment, activate the tractor's hoist to reach the working height, quick-release attachment bearing foot locking pin record the length of the tie rod, taking into consideration that the implement's PTO must be horizontal when the implement is at work, for adjustment of the top link tie rod, see page 42. lift the support foot as far from the ground as possible and secure this in place with the locking pin and lynch pin. Front hitching wheel kit secured chain It is essential to do the following when hitching the implement to the front of the tractor: fit the wheel kit; use a chain to connect the implement's upper attachment to the tractor. To connect the lower attachments on the implement to the corresponding front attachments on the tractor, carry out the same steps as described for rear attachment; to connect the chain to the top link, insert the pin into the hole shown and secure it with the lynch pin provided. A sufficient degree of slack in the chain must be allowed so that the implement can follow the movement of the wheels independently of the tractor; to enable this, insert the fixing pin into the most suitable link in the chain and secure it with the lynch pin. 36

37 Hitching the implement Mounting the wheels Do not assemble the machine yourself Trained personnel are required to assemble the machine. Do not perform assembly work yourself. The following points are required to be met for the machine to be in proper condition: Observance of the sequence of work steps. Compliance with tolerances and torques. Knowledge of work safety during assembly. Incorrect assembly can result in damage to the machine or accidents. If it is necessary to assemble the wheels, do not attempt to do this yourself; contact the retailer or a qualified technical support center. The qualified technical support center will proceed as follows: position the end of the wheel arms in line with the lower attachments on the machine, position the plain bearings in line with the lower attachment holes and insert them into the wheel arm holes, insert the lower plain bearings in the attachment holes, positioning them below the wheel arms, screw external plate tie rod pin and lynch pin lower plain bearing wheel arm internal plates nut lower plain bearing wheel arm external plate pin and lynch pin lower attachment lower plain bearing screw put the external plates in position and insert the screws, 37

38 Hitching the implement To facilitate insertion, lift and gently move the arms position the internal plates and the corresponding nuts, tighten nuts, position the tie rod as indicated in the figure, inserting the pins and securing them with the lynch pins, then adjust the working height instructions for adjusting the working height on page 41. Drive shaft Switch off the tractor and secure it Before you dismount: Disengage the PTO Lower all implements to the ground Place all controls in their neutral or park position Set the parking brake Switch off the tractor. Remove the ignition key. Secure the tractor against rolling away. An unsecured tractor can run you over or trap you. Otherwise, serious or fatal injury may be caused as a result. Attachment to the implement drive shaft set screw implement attachment The right drive shaft is usually already attached to the implement. When replacing the drive shaft, or following maintenance work, the drive shaft must be reattached to the implement. Carefully clean and lubricate the drive shaft coupling and the attachment to the implement Loosen and remove the set screw Push the drive shaft onto the implement attachment Insert the set screw. Gently move the drive shaft backwards and forwards to correctly insert the set screw in the attachment groove. Tighten the set screw, applying approximately: Nm for M10 screws Nm for M12 screws Nm for M14 screws In some cases, the drive shaft can be attached to the implement using a coupling collar or a pushbutton coupler. In this instance, the assembly process is similar to that indicated in the following paragraph. Attachment to the tractor Before connecting the drive shaft to the tractor PTO, check that the speed and direction of rotation comply with the usage instructions for the implement. Attach the drive shaft to the PTO of a tractor operating at 540 rpm or 1000 rpm, depending on the configuration of the implement. 38

39 Hitching the implement The implement can operate at two PTO input speeds (540 or 1000 rpm). Additional parts are not required to move from one speed configuration to another. All that is required is to change the positions of the lateral transmission pulleys; however, this must be carried out by an authorised workshop. pushbutton splined coupling splined coupling collar Carefully clean and lubricate the drive shaft coupling and the PTO shaft Push the pushbutton or slide the drive shaft collar Slide the coupling onto the PTO until the axis of the pushbutton or the bearings on the collar are lined up with the groove of the shaft Release the pushbutton or the collar as the coupling moves slightly Ensure that the pushbutton or the bearings of the collar are correctly inserted into the grooves in the shaft and that the drive shaft is correctly connected. Once the two ends of the drive shaft are connected, check that the two half guards rotate freely and independently, then attach the support chains for the protection tubes. The protection-tube chain of the drive shaft on the side of the implement can be attached to the dedicated point on the bottom of the three-point hitch. During work, check at regular intervals that the two joints are connected correctly. chain attachment point If the tractor is replaced, it may also be necessary to replace or upgrade the drive shaft. The drive shaft will be adapted by the retailer according to the type of tractor. In such cases, it is necessary to check that the drive shaft is of the right dimensions and that its length is correct in respect of the tractor specifications. The length of the two half-shafts must be such that during operation: The drive shaft tubes overlap by at least 1/3 of their length. They do not separate under any working conditions. The ends of the half-shafts do not reach the limit stop under any working conditions. Also: The difference in length between the protective tubes and the halfshaft tubes must be maintained, ensuring that they always provide maximum coverage of the sliding elements. If it is necessary to shorten the drive shaft, do not attempt to do this yourself; contact the retailer or a qualified technical support center. 39

40 Hitching the implement Hydraulic connection Hydraulic oil Hydraulic oil is dangerous, avoid all contact. In addition, pressurized oil easily penetrates skin and clothes, causing serious injury. Before commencing any work on the hydraulic system, switch off the tractor's engine and depressurize the system. Make sure the connection is correct Ensure that the hydraulic system is connected correctly, Otherwise, damage to the machine and personal injury may be caused as a result. If the chopper is equipped with the hydraulic lateral movement system: Shut off the engine, set the parking brake, remove the ignition key and secure the tractor against rolling away. Release any pressure from the tractor's hydraulic system Connect the quick-release couplings of the chopper's hydraulic hoses to the corresponding attachments on the tractor's hydraulic distributor. Check that the type of hydraulic connection between the implement and the tractor's hydraulic service couplers is such that the top link does not move when the remote control valve is not operated. The hydraulic cylinder for moving the implement frame is doubleacting. 40

41 Preparation for work Preparation for work Increased risk of injury It is strongly recommend that you observe the safety warnings given in the previous pages of this manual. Crushing, cutting and shearing hazards During the following operations, there is a risk of crushing, cutting and shearing injuries: act with caution and care, and take all the necessary steps to avoid dangerous situations. In particular, ensure the machine and components are properly supported and in a stable position! Adjusting the working height rear hitching Correct adjustment of the implement's working height provides the maximum return and the best results. In order to work correctly, the machine must be parallel to the ground and the rotor must operate at the right distance from the soil. In addition, the chopper PTO must be as horizontal as possible while the machine is functioning. 0 The working height is adjusted by modifying the position of the roller or the wheels, if fitted. Roller supported on skids The position of the skids that support the roller must be modified in order to vary the position of the roller (see following paragraph). front hitching 0 Under normal working conditions, the skids should not be in contact with the ground; in particular conditions (where there are holes, etc.), ensure that the blades cannot accidentally come into contact with the earth. Carry out any adjustments on a flat, firm and even surface. Adjust the roller to the desired position. Adjust the height of the lift arms so that the implement frame is parallel to the ground. Check the distance between the blades and the soil: generally, a distance of around 6 cm (2.4 in) is the correct adjustment. However, this distance should be increased when working with rocky or irregular soils. 0 Distance from the ground of the blades The blades must be at least 3 cm (1.2 in) from the ground when in operation. 41

42 Preparation for work Adjustment of the skids adjustment holes Proceed as follows on both of the skids (see figure below): raise and secure the implement, undo the locking screws, unscrew and remove the adjustment screw, the washers and the corresponding nut, vary the position of the skid until it is possible to insert the adjustment screw into a new hole, reposition the screw, the washers and the corresponding nut, The skids on both sides must be adjusted to the same position. locking screws adjustment screw tighten all the nuts. Adjustment of the wheels (Optional) To do this, proceed as follows (see figure below): > loosen the locking device, > rotate the sleeve on the tie rod, > re-tighten the locking device. Adjust the tie rod so that the implement becomes parallel to the ground and the conditions described above are met. sleeve locking device Adjusting the tie rod in the top link (only for rear hitching) correct adjustment The upper attachments of the implement have a slot which allows the implement to absorb any differences in the evenness of the ground, so it continues to support the roller correctly. After setting the working height, it is necessary to adjust the tie rod of the top link so that the implement can function properly. The tie rod is correctly adjusted if the fixing pin is in line with the inner end of the slot. Refer to the figure. 42

43 Lifting and transportation Lifting and transportation Adjustment of the supporting foot To ensure correct support, the machine is fitted with one adjustable foot (see figure). safety pin locking pin Support the machine Take all necessary precautions to prevent accidents caused by accidental falling of the machine during positioning and adjustment of the supporting foot. Ensure the machine is properly supported and in a stable position! To perform this operation, remove the safety pin and locking pin, move the foot to the desired position then reposition the locking pin and corresponding safety pin. Lifting lifting points Suspended load Take all necessary precautions to prevent accidents caused by accidental falling of the machine during the lifting. Ensure the machine is properly supported and in a stable position! While lifting and moving the implement, it is compulsory to ensure that safe distances are maintained. Only use the points indicated to attach the lifting device; see figure. Close jack. Before proceeding with the lifting, ensure that the tool's lateral movement jack is closed. Only this will allow the weight to be better distributed. The three-point hitch must be locked. In particular, in cases where the implement is equipped with mechanical movement, check that the locking device is positioned and secured correctly. Attach the implement to the points indicated with the appropriate fixing devices, lift the implement using a suitable lifting device, ensure that the support foot has been correctly positioned, place the implement on a suitable surface. If it is necessary to transport the implement on a truck: secure the implement so that it cannot move, all moving parts of the implement must be firmly secured. 43

44 Driving on the road Driving on the road The implement can be transported hitched to the tractor. Before driving on the road It is strongly recommend that you observe the safety warnings given in the previous pages of this manual. Check the width of the implement Implement must be in transport position. All moving parts of the implement must be firmly secured. Brake lights, reversing lights and direction indicators During transportation, the brake lights, the reversing lights and the direction indicators, as well as the tractor licence plate, must be clearly visible. If not clearly visible, the lights and licence plate must be attached to the implement. Removing dirt Remove any crop remains, stones and clumps of earth. When driving on the road, these foreign objects can become detached from the implement and cause accidents. wrapper bracket Marking for slow-moving vehicle SMV Additional markings are required for road transport or traveling on public roads in some U.S. states and some Canadian provinces. In general the SMV emblem is placed behind the tractor. Move the SMV emblem position from the tractor to the wrapper bracket of the machine in case of this obstructs the visibility of the Tractor SMV triangle. Transport position three point hitch locked Implement transported hitched to the tractor: centered frame. Before proceeding to transport, ensure that the the three-point hitch is centered positioned on the frame of machine. Only this will reduce the overall width. = centered frame = support foot raised The three-point hitch must be locked. Check that the type of hydraulic connection between the implement and the tractor's hydraulic service couplers is such that the top link does not move when the remote control valve is not operated. Support foot raised. Ensure that the support foot is as far from the ground as possible. Failure to respect these conditions when using the implement could lead to serious injury or death. 44

45 Use Use Increased risk of injury It is strongly recommend that you observe the safety warnings given in the previous pages of this manual. Check the danger zone The danger zone around the implement is 70 m (230 ft). Before starting up, opening and beginning operation as well as during operation, check the danger zone around the implement. Ensure good visibility. In unfavourable circumstances, objects may be thrown from the implement at high speed. Only start up and operate the implement if there are no people, animals or objects in the danger zone. Failure to respect these conditions when using the implement could lead to serious injury or death. Before raising the implement, disengage the PTO Do not lift the implement too high with the transmission in operation: the drive shaft could be forced to an excessive angle and break causing serious injury to the operator and damage to the implement itself. The maximum angle permitted for the drive shaft is 25. When lifting, always ensure that the PTO is disengaged when this value is approached or when there is a risk of exceeding it. Only work forwards The implement must be in the working position only when the vehicle is travelling forwards. When manoeuvring or reversing, disengage the PTO and lift it up. Keeping the implement in the working position could cause it to be seriously damaged. Ensure that the tractor and implement are aligned and stable Pay particular attention when using on uneven and/or sloping terrain, or when close to ditches or banks. Adapt speed, driving and use of the incline adjustment and lateral movement functions depending on the conditions of the terrain. Always check the stability of the tractor and implement. Failure to ensure stable conditions when using the implement could cause serious accidents or death. Set the tractor's lift arms to the float position Set the tractor's lift arms to the float position; the arms must not be locked while working, as this will create a poor cut and cause premature wear on the blades 45

46 Use Working Working with the chopper is a particularly hazardous activity, and for this reason requires very close attention from the operator. This manual provides only general warnings and advice. All situations must be evaluated by the operator. Ensure that there is no debris (wood, metal, plastic, glass, etc.) in the working zone which could be thrown from the implement or damage it. Starting up Lift the machine slightly so that it can be started up without coming into contact with the material to be cut Engage the PTO and slowly increase the rotation speed Lower the implement until it reaches the working position and gradually increase the PTO speed, until working speed is reached (540 or 1000 rpm depending on the model). Working speed The working speed should be regulated according to several criteria: the type and conditions of the material to be cut the desired fineness of the worked material The greater the working speed, the lower the quality of the cut material Obstruction When working with vegetation that is too dense, too damp or at excessive working speeds, the implement can become clogged. In such cases, the tractor engine speed will fall and the results will not be optimal. At the first signs of clogging: reduce the working speed of the tractor lift the chopper slightly If the clogging persists, please refer to the «Maintenance» section. Hydraulic lateral movement It is possible to vary the movement during operation, to adjust it to working requirements. Simply operate the corresponding function on the tractor hydraulic distributor. Lateral movement during the chopping: do not perform this operation when the implement is in contact with the ground. This could lead to stress being exerted which could cause damage. Do not raise the implement more than strictly necessary to avoid the contact from the ground. 46

47 Use Lift the implement Actuate the tractor's distributor to achieve the desired movement. Lower the implement again. Abnormal noise and vibrations If abnormal noise or vibrations are noted during use, stop the implement immediately and, whilst observing safety precautions, remove the cause of the problem or if necessary contact your retailer. Finishing work To stop the implement, reduce the tractor's engine speed and remove the PTO. Warning: moving rotor After disengaging the PTO, the rotor on the implement will continue to rotate for a few seconds due to inertial force. Wait until all parts have stopped moving completely. Safety guards Safety guards correctly installed Check carefully that all the safety guards are present and correctly installed on the machine. Periodically check the condition of the safety guards and replace them immediately if they are damaged In particular: the PTO cover the drive shaft guards the front safety guards the rear deflector. description of the implement on page31 The deflector may be removed for maintenance and cleaning operations without infringing the safety regulations, but when the machine is operating it must be assembled and locked with the correct fasteners. Working position Correct positions of work It is forbidden to operate the machine with the tractor straddling a ditch. 47

48 Cleaning and care Cleaning and care Cleaning Clean the implement by washing with gentle detergents. Ensure that components that could be damaged by penetration are adequately protected. Take care when using pressurized water jets If using a pressurized water jet for cleaning, do not hold it too close to the implement and avoid directing it directly onto any parts that could be damaged or affected by penetration; in particular, pay attention to vent plugs, bearings, washers, seals, hydraulic hoses, housing, etc. When cleaning the jack shaft, be careful not to scratch it When you have finished washing the implement, it is recommended that you dry it carefully. Cleaning is an ideal occasion to check the condition of the implement: check for any defects and take steps to eliminate them. 48

55 Maintenance Lubricants \ CAUTION Use only prescribed lubricants Is prohibited mixing different type of lubricants. Impermissible lubricant mixture can damage the components of machine. Observe the correct fill quantities Observe the correct lubricant fill quantities. Check them regularly. A lubricant level which is too low or too high may result in damage to the machine. Greasing operations Grease specifications The following figure shows the position of the grease fittings on each component. There may be additional grease fittings on the implement to those shown in this operator s manual; usually greasing points are positioned near the joints, moving parts and bearings. For this reason, please check the entire implement for greasing points. NLGI 2 DIN K2K-20 Greasing the bearings The bearings should be lubricated on a regular basis: as per the maintenance table, after being subjected to high stress levels, at least once a season. Bearings that do not need maintenance work should not be lubricated. Working with the pneumatic grease gun: Lubricate by pressing 1-2 times on the pneumatic grease gun. If resistance is felt from the pneumatic grease gun on the second pump, stop the operation. Excessive quantities of grease lead to the oil seals moving from their positions, allowing dirt and dust to penetrate inside the bearings, which leads to premature wear. The grease nipple for the left-hand bearing on the rotor can be accessed by removing the corresponding cap on the transmission cover. Sliding sleeve greasing Grease nipple for the sliding sleeve The grease nipple for the sliding sleeve on the upper transmission can be accessed by removing the corresponding cap on the transmission cover. To proceed with the greasing of the sliding sleeve on the upper transmission, the top link attachment must be moved to the left (lateral movement jack closed) (see figure). The required quantity of grease for the lateral movement system is roughly three pumpfuls. 55
