quality hydraulic fluid. Check the level of the hydraulic fluid before the engine is first started and daily thereafter. The recommended replacement fluid is as follows: 1. Position the machine on a level surface, lower the cutting units, stop the engine, and remove the key. 2. Clean the area around the filler neck and cap of the hydraulic tank (Figure 15). Remove the cap from the filler neck. Toro Premium All Season Hydraulic Fluid (Available in 5 gallon pails or 55 gallon drums.
Stopping the Engine • The engine has ceased running due to lack of fuel. Important: Allow engine to idle for 5 minutes before shutting it off after a full load operation. This allows the turbo charger to cool down before shutting the engine off. Failure to do so may lead to turbo-charger trouble. • Maintenance has been performed upon the fuel system components. Refer to Bleeding the Fuel System in Fuel System Maintenance, page 35. 1.
To check the operation of the interlock switches, perform the following procedure: 1. Drive the machine slowly to a large, relatively open area. Lower the cutting unit, stop the engine, and apply the parking brake. 2. Sit on the seat and depress the traction pedal. Try to start the engine. The engine should not crank. If the engine cranks, there is a malfunction in the interlock system that should be corrected before beginning operation. 3. Sit on the seat and start the engine.
Standard Control Module (SCM) Therefore, allow the traction pedal to move backward as the engine RPM decreases, and depress the pedal slowly as the RPM increases. By comparison, when driving from one work area to another, with no load and cutting unit raised, have the throttle in the Fast position and depress the traction pedal slowly but fully to attain maximum ground speed. The Standard Control Module is a "potted" electronic device produced in a "one size fits all" configuration.
Figure 17 Here are the logical troubleshooting steps for the SCM device. 1. Determine the output fault you are trying to resolve (PTO, START, or ETR). 2. Move key switch to "ON" and ensure the red "power" LED is illuminated. 3. Move all input switches to ensure all LED’s change state. 4. Position input devices at appropriate position to achieve the appropriate output. Use the following logic chart to determine the appropriate input condition. 5.
After Operating input LED’s to ensure it matches the logic chart. To ensure optimum performance, clean the underside of the mower housing after each use. If residue is allowed to build up in the mower housing, cutting performance will decrease. If the input LED’s are correct, check the output LED.
