c. Engine Warm-Up (Above 0 F (-18 C)).
The warm-up period depends on the ambient temperature. Care should be taken at lower temperatures
to allow vehicle to warm up sufficiently.
Operate vehicle carefully, avoiding high loads and speeds until temperatures and pressures reach normal operating
range. During operation of vehicle, operator should:
Monitor instruments regularly.
Stop vehicle and carry out troubleshooting procedures if any warning indicators or buzzers come on.
Be aware of unusual noises or handling characteristics. If this occurs, stop the vehicle and carry out
The brake low-pressure indicator and warning buzzer should both turn off within 3-4 min. of engine
starting. If this fails to happen, switch engine off and investigate the cause of the alarm.
Check instruments after engine has been running for 3-4 min. All warning indicators should be off. If any warning
indicators remain on, stop engine and investigate the cause of the alarm.
d. Cold Weather Warm-Up (0 F (-18 C) and Below).
In addition to the normal warm-up procedures, the hydraulic systems will require additional warm-up procedures during
very cold weather (0 F (-18 C) and below).
During cold weather operations, the hydraulic functions may operate slowly. Do not attempt
Front-End Loader (FEL) or backhoe operations until the hydraulic oil has reached operating
To allow hydraulic oil to reach normal operating temperature:
Run engine at half speed for 5 min.
Cycle boom and bucket functions until hydraulic oil has reached normal operating temperature and functions
move at normal speed.
e. Shutting Engine OFF.
Ensure EGS lever is in N (Neutral) position
Turn ignition switch (1) to OFF position.
