Piston (traction) pump is worn or damaged (see Piston (Traction) Pump Flow Test in the Testing section of this chapter).
Page 80: Lift/Lower Circuit Problems
Lift/Lower Circuit Problems Problem Possible Cause Gear pump is noisy (cavitation). Reservoir oil level is low. Gear pump suction line is restricted. Gear pump suction line has an air leak. Cutting units will not lift or lift slowly. Engine speed is too low. Reservoir oil level is low (other hydraulic systems affected as well).
Page 81: Adjustments 5
Steering Circuit Problems Problem Possible Cause Steering wheel is hard to turn. Power steering valve has insufficient oil flow (lift and charge circuits affected as well) (see Steering/Lift Circuit Gear Pump Flow Test in the Testing section of this chapter). Emergency steering ball in power steering valve is missing or dam- aged.

Turf Guardian Leak Detector System Operation (Optional Kit) NOTE: The Turf Guardian Leak Detector System is optional on Greensmaster TriFlex Hybrid machines. Before Start-Up (Cold Oil) With ignition switch OFF, solenoid valve is open. Before OIL LEVEL SENSOR start-up, hydraulic fluid is at level mark of sight gauge (oil LEAK DETECTOR (raised/open) cold).
Page 157 Leak Alert! If hydraulic fluid leaks during operation, the fluid level in OIL LEVEL SENSOR LEAK DETECTOR the main hydraulic tank drops. This causes the oil level (lowered/closed) TANK sensor float to lower, closing the alarm circuit. The alarm will sound and the console indicator light will illuminate SIGHT after a one (1) second time delay.

The meter can test electrical components and circuits for current, resistance or voltage. Obtain this tool locally. NOTE: Toro recommends the use of a DIGITAL Volt-- Ohm--Amp multimeter when testing electrical circuits. The high impedance (internal resistance) of a digital me- ter in the voltage mode will make sure that excess cur- rent is not allowed through the meter.

Turf Guardian Leak Detector Oil Level Sensor (If Equipped) NOTE: The Turf Guardian Leak Detector System is optional on Greensmaster TriFlex Hybrid machines. The leak detector oil level sensor closely monitors the hydraulic fluid level in the main hydraulic reservoir. The sensor is open when the sensor float is in the raised position and closed when the float is in the lowered posi- tion.

Turf Guardian Leak Detector Alarm (If Equipped) NOTE: The Turf Guardian Leak Detector System is optional on Greensmaster TriFlex Hybrid machines. Machines equipped with the Turf Guardian Leak De- tector System include an alarm that sounds if a hydraulic leak is detected by the system. The alarm is attached to the outside of the control console assembly.
