Start the engine, set the throttle to a reduced speed, push down on the handle to raise the cutting unit, press the operator-presence control, move the traction lever to the ENGAGED position and transport the machine onto the collar of the green (Figure 30).
Operating the Controls after Mowing 1. Drive off the green, move the reel drive and traction control levers to the DISENGAGED position, and shut off the engine. 2. Empty the grass basket of clippings, install the grass basket on the mower, and transport the machine to storage. Checking the Operation of the Interlock Switches g032412 Service Interval: Before each use or daily Figure 31 1.
Releasing the Transmission the interlock switch needs service. Correct the problem before operating. Refer to Servicing the Traction Interlock Switch (page 30). If the machine becomes disabled, you can disengage the drum from the transmission to allow the machine to be maneuvered. 3. Carefully lower the machine off the kickstand. 1. On the right rear corner of the machine, locate the traction engage/disengage lever next to the drive housing drum (Figure 32). Checking the Brake-Interlock Switch 1.
Setting the Machine to Match Turf Conditions Use the following table to set the machine to match turf conditions.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Important: When using the machine in conjunction with the Trans Pro 80, always use the stops on the trailer when servicing the machine. Overtipping can result in fuel spills. The stop on the Rail Ramp Kit requires inserting a broom handle or similar item through the holes behind the wheels.
Daily Maintenance Checklist Important: Duplicate this page for routine use. Maintenance Check Item For the week of: Mon. Tues. Wed. Thurs. Fri. Check the safety interlock operation. Check the parking brake operation. Check that pivot joints operate freely. Check the fuel level. Check the engine oil level. Check the air filter. Clean the engine cooling fins. Check for unusual engine noises. Check for unusual operating noises. Check the reel-to-bedknife adjustment. Check the height-of-cut adjustment.
Engine Maintenance Servicing the Engine Oil Fill the crankcase with approximately 0.6 L (20 fl oz) of the proper viscosity oil before starting. The engine uses any high-quality oil having the American Petroleum Institute (API) service classification SE or higher. Select the proper oil viscosity (weight) based on the ambient temperature. Figure 33 illustrates the temperature/viscosity recommendations. 1 2 g018270 g018270 Figure 34 1. Oil-level gauge 2. Drain plug 3.
3. Push down on the handle to tip the machine and engine backward, allowing all the oil to run into the drain pan. 4. Install the drain plug and refill the crankcase with the specified oil. 5. Wipe up any spilled oil. 6. Dispose of the used oil properly. Recycle as per local codes. Servicing the Air Cleaner Service Interval: Every 50 hours 1. Make sure that the wire is off the spark plug. 2. Remove the wing nut securing the air-cleaner cover to the air cleaner and remove the cover.
Servicing the Spark Plug Fuel System Maintenance Service Interval: Every 100 hours Use an NGK BR6HS spark plug or equivalent. The correct air gap is 0.6 to 0.7 mm (0.024 to 0.028 inch). Cleaning the Fuel-Tank Screen 1. Pull the molded wire off the spark plug (Figure 38). Service Interval: After the first 20 hours Every 100 hours/Monthly (whichever comes first) 1 1. Unscrew and remove the fuel-tank cap from the fuel tank (Figure 40). g018272 g018272 Figure 38 1. Spark-plug wire 2.
Servicing the Brake-Interlock Switch Electrical System Maintenance 1. Make sure that the engine is off. Servicing the Traction Interlock Switch 2. Remove the control panel. Use the following procedure if the switch needs adjustment or replacement. 4. Loosen the interlock switch mounting fasteners (Figure 42). 3. Engage the service-brake lever and engage the parking-brake latch. 1. Make sure that the engine is off. 2. Remove the control panel. 3. Engage the traction lever. 3 g016913 Figure 42 1.
Brake Maintenance Belt Maintenance Adjusting the Service/Parking Brake Inspecting the Reel-Drive Belt If the service/parking brake slips when operated, adjust the cable as follows: Service Interval: Every 1,000 hours 1. Loosen the flange bolt securing the belt cover and remove the belt cover to expose the belt (Figure 44). 1. Move the service/parking brake lever to the OFF position. 2. Remove the control panel. 3.
Engaging/Disengaging the Transmission-Belt Tensioner C. Clean any debris from inside the belt compartment and from around the compression spring (Figure 45). D. Make sure that the compression spring is applying the proper tension on the belt. The transmission belt is tensioned by a spring loaded idler pulley. If the belt tension has to be engaged/disengaged, use a 3/8 inch wrench to rotate the engage/disengage shaft (Figure 46) to the desired position.
Controls System Maintenance D. Install the turnbuckle to the spring using the clevis pin. Adjusting the Traction Control F. E. Move the traction control to the ENGAGED position. Service Interval: Every 500 hours—Replace the clutch oil. Measure the distance from the pin on either end of the traction-control spring (Figure 48); repeat steps A through F until it is within 7.3 to 7.6 cm (2-7/8 to 3 inches).
Storage 1. Remove any grass clippings, dirt, and grime from the external parts of the entire machine, especially the engine. Clean the dirt and chaff from the outside of the engine cylinder-head fins and the blower housing. 1 Important: You can wash the machine with mild detergent and water.
