All systems
High altitude and ambient temperatures can have an effect on the temperature of hydraulic fluid. Fluid that is too
cool is thick and causes increased friction and poor lubrication. Fluid that is too hot is thin, which accelerates
wear on the parts, increases the formation of sludge, degrades the fluid, and decreases its lubrication and
protective qualities.
Increased temperature can mean that there is a problem with the cooling system.
A sensor monitors the hydraulic fluid temperature in the tank.
The cord for the hydraulic fluid temperature/level sensor is unplugged or damaged.
 Plug in the sensor.
 Replace the cord.
The temperature sensor is faulty or damaged.
Replace the sensor.
When the hydraulic fluid temperature is 55°C (131°F):
 At 45°C (113°F), a switch closes to start the cooling fan.
 The operator interface shows Warning: Hydraulic Fluid >55C.
 The beacon light flashes amber.
 The fan operates for 10 minutes.
If the hydraulic fluid temperature is lower than 55°C (131°F) after 10 minutes, the fan turns off.
If the hydraulic fluid temperature is higher than 45°C (113°F) after 10 minutes, the fan continues operating.
When the hydraulic fluid temperature is 65°C (149°F):
 The operator interface shows Fault 1: Hydraulic Fluid >65C
 The beacon light flashes red.
 The intensifier turns off.
 The pump operates in cooling mode for 3 minutes.
If the temperature remains at or higher than 65°C (149°F):
 The operator interface shows Fault 2: Hydraulic Fluid >65C for >3 Minutes
 The primary motor turns off.
The sensor is not sensing the correct temperature
The operator interface shows a hydraulic fluid temperature alarm
