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 does not go out within ten seconds, stop the engine and investigate the cause before starting again. Turbocharger damage can result, if the engine speed is not kept low until the engine oil pressure is sufficient. |
Run the engine at low idle. Cycle all hydraulic controls in order to allow warm oil to circulate through all hydraulic cylinders and through all hydraulic lines. This will aid the warm-up of the hydraulic components.
To speed the warming of the hydraulic oil, hold the lift control in the RAISE position for short periods. This will allow the hydraulic oil to reach relief pressure so that the hydraulic oil warms more rapidly.
Note: Do not hold the lift control in the RAISE position for more than ten seconds.
Observe the indicators and the gauges frequently.
Cycle all controls in order to allow the warm oil to circulate through all hydraulic cylinders and through all hydraulic lines.
While you idle the engine for warm-up, observe the following recommendations:
- In temperatures above 0°C (32°F), the suggested warm-up period is 15 minutes.
- In temperatures below 0°C (32°F), the warm-up will require a period of at least 30 minutes.
- If the temperature is below -18°C (0°F) or if the hydraulic functions are sluggish, the warm-up may require a longer period of time.
