HYDRAULIC SYSTEM
TEST PORT NOMINAL PRESSURE READINGS
Note: See Figure 15 and the GENERAL HYDRAULIC SPECIFICATIONS TABLE.
Note: 100 psi = 6.9 bar
1 Insert the pressure gauge into the test port.
Note: The Lower Test Port (TP 4) on the Scrub Lift Cylinder is easier to access if you lower the scrub deck.
2 Run the engine in high throttle position and allow the hydraulic oil to warm up.
The bypass pressure is the pressure reading with no motor or cylinder operating.
The operational pressure is the pressure range in which the motor or cylinders will operate.
A much lower than normal bypass pressure could indicate a gear pump problem.
If the bypass pressure remains the same after turning the function on, there could be a problem in the control valve or circuit.
If the operational pressure is within range but the motor speed is too slow, the problem could be in the motor.
If the broom motor operational PSI reading is above the bypass psi but is below the operational psi, check the broom adjust-
ment and wear.
Check individual system troubleshooting sections of this manual for additional information.
