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.
Allow a cold engine to warm up at LOW IDLE for at least five minutes.
Look at the gauges and the indicator lights frequently during operation.If the alternator indicator lamp remains illuminated, inspect the machine for the cause of the trouble. If the gauges do not respond properly, inspect the machine for the trouble. Before moving the machine, repair all problems.
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 15 minutes.
In temperatures below 0°C (32°F), the warm-up period is 30 minutes or a longer period of time.
In temperatures below -18°C (0°F), more time is required if the hydraulic controls are sluggish.
