Note: The monitoring system will perform a self test when the engine is started. Always allow the monitoring system to complete the self test before you begin operating the machine.

Allow a cold engine to warm up at low idle for at least five minutes. To help the hydraulic components to warm up faster, engage the attachment controls and disengage the attachment controls.
Cycle all controls in order to allow warm hydraulic oil to circulate through all hydraulic cylinders and through all hydraulic lines.
Look at the indicators and the gauges frequently during operation.

While you idle the engine, observe the following recommendations:

Allow the engine to warm up for approximately 15 minutes when the outside temperature is higher than 0°C (+32°F).
Allow the engine to warm up for approximately 30 minutes when the outside temperature is below 0°C (+32°F).
More time may be required if the outside temperature is less than −18°C (0°F). More time may also be required if the hydraulic functions are sluggish.
