NOTICE

Keep engine speed low until the engine oil pressure registers on the gauge or the engine oil indicator light goes out.

If it does not register or the light go out within ten seconds, stop the engine and investigate the cause before starting again. Failure to do so, can cause engine damage.


  1. Allow a cold engine to warm up at low idle for at least five minutes. Engage the implement controls and disengage the attachment controls in order to help warm-up of the hydraulic components.

    Cycle all of the controls in order to allow the warm oil to circulate through all of the cylinders and all of the lines.

    When you run the engine at low idle in order to warm up the engine, observe the following recommendations.

    • If the temperature is over 0°C (+32°F), idle the engine for approximately 15 minutes.

    • If the temperature is below 0°C (+32°F), idle the engine for approximately 30 minutes or more.

    • If the temperature is below -18°C (0°F), more time may be required in order to warm up the engine.

    • If the hydraulics are sluggish, more time may be required in order to warm up the engine.

  1. All fault lights should turn off. The fault alarm should turn off. If the fault lights do not turn off, stop the engine. Make any necessary repairs before you start the engine.
