5 1. Description of the machine, intended use and lay-out of the controls 1.1. Basic description of the machine The machine is a double-drum Ride-On Tandem Roller, powered by a water cooled Kubota Diesel engine. The machine s drive systems for the propulsion of the machine, as well as for its steering are hydro-static, powered by engine-mounted hydraulic pumps. Both drums are permanently driven by a hydraulic motor directly mounted on each drum. The system allows the operator to operate the machine at infinitely variable speeds in both directions. The machine s Drive system incorporates a HIGH / LOW Speed Range selection facility, which enables the machine to negotiate steep inclines and berms. The machine is equipped with an automatic Parking Brake which will mechanically prevent the machine from moving backwards or forward, as soon as the engine has stopped. As an Option the Parking Brake can also be manually engaged by depressing the red Emergency Stop Button located on the instrument panel. This procedure, however, is reserved for EMERGENCIES ONLY and must not be used for normal stopping of the engine!!! There is provision for manual release of the brake, should this be required. The machine s upper frame is isolated from the drums by Rubber Buffers. The machine is equipped with a Protection Structure / Sunroof which will protect the operator in the event of the machine falling onto its side. 1.2 Intended use of the machine The machine is intended to be used for compaction of all types of materials / surfaces occurring on Cricket Pitches. 1.3 Limitations of intended use of the machine The machine may not be used on hard surfaces such as existing asphalt, concrete, etc. Page5

Operation of the machine by under aged youngsters or persons under the influence of drugs/alcohol is specifically prohibited. The operator must at all times have the Seat Belt fastened and properly tightened whenever the machine is in motion a loose Seat Belt may result in injury or death of the operator in case of an accidental fall of the machine. No passengers are allowed on the Roller at any time. Take extra care when ground conditions (condition and inclination of surface) change machine could slide unexpectedly. Be extra cautious near edges of trenches, pits or embankments, where the ground could collapse unexpectedly. Never start the engine when not seated in the driver s seat danger to be driven over by machine! Be careful when opening the bonnet there could be hot areas (exhaust, radiator, etc.) and there could be moving parts Do not leave the machine unattended with the engine running When machine needs to be parked on an incline, always place a wedge or some rocks in front of the drums Page8

9 2.2 Lifting the machine and tying it down for transport Lifting and tying-down not permitted at any other points on the machine! Always use suitable and adequately rated Lifting Gear when lifting the machine! Never stand below / near suspended loads! Page9

10 2. Operation of the machine 3.1 Starting and stopping of the engine Visual checks before starting the engine Check engine oil level (on dip stick) (if necessary top up with SAE 15W40) Check the coolant level on the radiator Check hydraulic oil level Check fuel level (Fuel Gauge) Ensure that the Drive Lever is in its NEUTRAL position Ensure that the Rotating Beacon is working (check with Ignition switched ON) Ensure that the Reverse Buzzer is functioning (move Control Lever into REVERSE with Ignition ON) Starting the engine 1.1. If fitted, ensure that the Emergency Stop button is in the OPERATING position (raised position) 1.2. Turn Master Switch into ON position 1.3. If engine is cold: Engage the Pre-Heat function, see below (max. 10 seconds) 1.4. Turn Ignition Key clockwise to start the engine the engine will accelerate to full throttle speed automatically 1.5. Check instruments / warning lights on the dashboard for any unusual readings or indications When the engine is cold it is good practice to pre-heat the engine (by engaging the Glow Plug for a few seconds before starting) and then letting the engine run for 2 3 minutes before engaging any load this will give the engine and the hydraulic oil a chance to warm up to reasonable operating temperature. Page10

3.1.3 Stopping the engine Turn Ignition Switch anti-clockwise to switch the engine OFF When leaving the machine or parking it, it is good practice to turn the Master Switch into the OFF position In

11 3.1.3 Stopping the engine Turn Ignition Switch anti-clockwise to switch the engine OFF When leaving the machine or parking it, it is good practice to turn the Master Switch into the OFF position In an EMERGENCY the Emergency Stop Button may be activated by pressing it down this will kill the engine instantly, engage the Parking Brake and will stop all functions of the machine. This procedure is reserved for EMERGENCIES ONLY and must not be used for normal stopping of the engine!!! 3.2 Moving the machine forward and backwards The forward / reverse movement of the machine is controlled with the hand control lever situated on the RH side of the control station (1) 1 Pushing the lever FORWARD will make the machine move FORWARD, pushing it BACKWARDS will make the machine move BACKWARDS the further the lever is pushed, the faster the machine will move in the desired direction When changing direction, do this in a SLOW movement of the lever to allow the machine to change direction SMOOTHLY never go from fully forward into fully reverse! The Control Lever is designed as a Dead Man s Handle it will automatically return into its NEUTRAL position as soon as the operator lets go of the Lever, and the machine will automatically come to an immediate stop. 3.3 Selecting the HIGH or LOW speed range For normal operation on reasonably flat grounds, the range selector lever is to be placed in the HIGH position (1) 1 2 For negotiating of steep inclines or berms the selector lever is placed into LOW position (2). In this setting the machine will have increased (double) climbing ability but with reduced (half) propulsion speed. Page11 The selector lever should only be shifted when the machine is stationary.

12 4. Tips for getting best compaction results 4.1 General Hints and Tips for the operator Due to the delicacy of a perfect surface of the Cricket Pitch, the instructions given by the Captain / Umpire will always be final to the operator of the Cricket Pitch Roller. Below are a few general tips for correct operation of the STAMPEDE Cricket Pitch Roller. o To get good compaction results, you always need to run the machine SLOWLY as a rule-of-thumb this means about half of normal walking speed o When starting a run or when changing direction of the machine, do this gently, to avoid spinning of the rollers on the ground. Gentle movement of the Control Lever will give you smooth acceleration and deceleration of the machine o Never change direction of the machine by going from full speed in the one direction to full speed in the reverse direction. o Never do major articulation (steering) movements when the machine is stationary, this will result in a scuffing action of the drums on the surface. o Overlapping during the rolling process and number of passes will be determined by the Captain / Umpire but should then be done in a consistent method o Never run machine over hard materials, (e.g. concrete, hard asphalt, etc.) for travelling over such areas and for longer distances do this with care and do not exceed normal walking speed Page12

13 4.3 Working on slopes and near embankments that can collapse Always operate machine UP and DOWN slopes or hills never from side to side max. max. Always work your Roller TOWARDS the edge of the embankment with the operator out of the danger zone; see below Page13

14 4. Daily Maintenance checks / actions The listing below shows the routine Daily Maintenance items, which may be performed by the operator Clean the machine, in particular any build-up of soil or asphalt in the area of the drums Refuel the machine preferably this is done at the end of the shift to avoid entry of water into the fuel tank due to overnight condensation Check the engine oil level must be between the MIN and MAX marks of the dipstick, when machine is parked on level ground Check the hydraulic oil level at the sight glass on the hydraulic tank must be at least ¾ full when machine is cold Check the Airfilter element, and clean as required handle and re-install with absolute care! Check for any loose bolts or nuts, oil leaks and any unusual noises report any unusual findings to Supervisor / Foreman Every week: check Water Trap and drain water sediment, as required CLEAN MACHINES ALWAYS WORK BETTER Page14

15 1. Servicing General, and Servicing the Roller 1.1 General Due to the inherent nature of danger during the servicing / adjustments to Construction machinery, all servicing should be performed by suitably qualified persons only, and with the use of suitable tools and in appropriate locations with required facilities. Should specific details or advice be required, this should be obtained from STAMPEDE s Service Centre personnel. Service items and spare parts should always be obtained from STAMPEDE, where they are guaranteed for consistent quality and fitness for purpose. 1.2 Roller Servicing Schedule The following table lists all regular Service / Routine Adjustment items that need to be performed at the specified intervals and with the specified servicing consumables Item # Service item Service Interval Service Consumable Quantity / Spec. 1 Lubrication of the Articulation Joint 1 month EP2 grease 2 nipples 2 Lubrication of the Steering Cylinder 1 month EP2 grease 2 nipples 3 Replacement of Hydraulic Filter Element in the return-line filter 12 Part No. OMTPR100-2-GN 1 (on top of hydraulic tank) months 4 Replacement of Breather Filter Element (on top of hydraulic tank) 12 months Part No. OMTPR100-2-AB 1 5 Hydraulic oil change 24 months Hydraulic Oil grade 68-ISO *) 6 Cleaning (or replacement) of Suction 24 Part No. Strainers in hydraulic tank months RR Water Trap / Primary Fuel Filter Part No. a) Cleaning of the Water Trap 1 month KS L 1 b) replacement of filter in the bowl 3 months 8 Replacement of secondary fuel filter 3 months Pt.

20 #10 Preparing the machine for towing In the event of the machine needing to be towed, the machine s drum drive system must be set to free wheeling which consists of 2 steps as described below Manually releasing the Parking Brake The machine is equipped with a Parking Brake which is incorporated in the drive motor on each drum. The Parking Brake is applied automatically when the engine comes to a stand-still or when the EMERGENCY STOP Button is depressed. To manually release the brake, do the following: 1. Remove the 2 plugs (1) to get access to the release screws below 2. Insert Allan key and press and turn each release screw (2) in until its threads catch in the brake plate. Tighten each screw until the spring on each screw is fully compressed (at this point you will feel a substantial difference in the resistance to turn it) 3. Now, continue to tighten (turn clockwise) the two release screws to compress the brake plate springs. Alternate back-and-forth between the two screws, turning them approximately 45 at a time, until the drums are no longer blocked by the brake plate. The brake plate should release after having turned each screw approximately 120 in total. To test if the brake is free, manually turn the drum To undo the manual release of the Parking Brake, turn (anti clockwise) both release screws back into their original position and re-install the 2 plugs. Thereafter check for proper functioning of the Parking Brake. 2 1 See also diagram on next page Page20
