NOTICE

Keep the engine speed low until the engine oil indicator light goes out.

If 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.



NOTICE

Steering the machine completely to the steering stops while the hydraulic oil is below 0 °C (32 °F) can damage the steering system.

In temperatures below 0 °C (32 °F) work warm oil into the system by steering only a small amount at a time in each direction. Slowly increase the amount of each turn before steering completely to the steering stop.


  1. Allow a cold engine to warm up at LOW IDLE for at least five minutes.

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

Observe the following recommendations during the warm-up period for the engine:

  • In temperatures above 0°C (32°F), the warm-up period is 5 minutes.

  • In temperatures below 0°C (32°F), the warm-up period is 15 minutes or a longer period of time.

  • In temperatures below −18°C (0°F), more time is required if the hydraulic controls are sluggish.
