Keep engine speed low until the engine oil pressure alert indicator goes out. If the alert indicator 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. |

DO NOT OPERATE ANY HYDRAULIC SYSTEM WHEN THE ENGINE IS RUNNING AT THE LOW IDLE SPEED. Operating the hydraulic systems will stall the engine and may damage the engine. Wait until the engine speed is greater than 1200 RPM to operate the hydraulic systems. |
- Allow a cold engine to warm up at low idle (less than 1000 rpm) for at least five minutes.
- After five minutes, increase the engine speed above 1200 rpm.
- Cycle all hydraulic controls in order to allow warm hydraulic oil to circulate through all hydraulic cylinders and through all hydraulic lines.
After the engine has started and the engine is idling, observe the following recommendations:
- Allow the engine to warm up for 10 minutes when the ambient temperature is higher than 0°C (+32°F).
- Allow the engine to warm up for 15 minutes when the ambient temperature is below 0°C (+32°F).
- More time may be required if the ambient temperature is less than -18°C (0°F) or if the hydraulic functions are sluggish.
Note: The warm-up times may be greatly reduced if the preheat system (if equipped) is activated.
