Faults
The hydraulic fluid is too hot.
Refer to Temperature on page 162.
The intensifier is overstroking.
Refer to The intensifier overstrokes in 1 direction on page 158.
The supply pressure is lower than 2.8 bar (280 kPa / 40 psi).
Increase the supply pressure.
Pressure is lost because of a leak.
Identify the source of a leak and correct the problem.
The supply water is turned off.
Turn ON the supply water.
The hydraulic fluid is too hot.
Refer to Temperature on page 162.
The temperature sensor in the hydraulic fluid tank has failed.
Replace the sensor.
A hydraulic fitting or a hydraulic hose is leaking.
Fix the leak. Refer to Leaks on page 165.
