Keep the engine speed low until the engine oil pressure registers on the gauge or until the engine oil indicator light goes out. If it does not register or the light does not go out within ten seconds, stop the engine and investigate the cause before starting again. Failure to do so, can cause engine damage. |
Note: The hydraulic lockout control must be in the LOWERED position before the hydraulic controls will function.
- Allow the engine to warm up at low idle for 5 minutes. Engage the joysticks for the work tool control and disengage the joysticks for the work tool control. This will speed up the warm-up of the hydraulic components. If the temperature is less than
− 18°C (0°F) or if hydraulic functions are sluggish, additional time may be required. - To warm up the hydraulic oil, turn the engine speed dial to the medium engine speed. Run the engine for approximately five minutes and move the joystick intermittently from the BUCKET DUMP position to the HOLD position. Do not hold the joystick in the BUCKET DUMP position with the bucket cylinder fully extended for more than 10 seconds.
- Move the governor control lever to the maximum engine speed. Repeat Step 2.
This allows the oil to attain relief pressure, which causes the oil to warm up more rapidly.
- Cycle all controls in order to circulate warm oil through all hydraulic cylinders and through all hydraulic lines.

When you cycle the machine controls, the machine can move suddenly. Contact between the machine and external objects or ground personnel can result in serious injury or death. Before you cycle the machine controls, the machine should be located in an unobstructed, hazard-free work area that is away from external objects and ground personnel.
- Observe the gauges and the indicators frequently during the operation.
