NOTICE

Keep the engine speed low until the engine oil fault alarm shuts off and the indicator light shuts off. Wait for ten seconds. If the indicator light stays on, stop the engine. Investigate the cause of the problem before you start the engine again.


  1. Warm up the engine at low idle for five minutes. With the boom in the LOCKED position, cycle the hydraulic cylinders in order to circulate the oil. Move the control for the boom to the BOOM DOWN position for one minute. Release the control for the boom for one minute. Repeat this procedure until the hydraulic system is warm enough to operate the attachments.

  1. Monitor the gauges while you operate the machine controls.

  1. The parking brake indicator will remain on until you release the parking brake.

While you idle the engine for warm-up, observe the following recommendations:

  • If the temperature is greater than 0° C (32° F), warm up the engine for approximately 15 minutes.

  • If the temperature is less than 0° C (32° F), warm up the engine for approximately 30 minutes.

  • If the temperature is less than - 18°C (0°F) or if hydraulic functions are sluggish, additional time may be required.
