OPERATOR MAINTENANCE
OPERATION IN COLD, RAINY, OR SNOWY WEATHER
INITIAL SETUP: NOT APPLICABLE
OPERATION IN RAINY OR SNOWY WEATHER
CAUTION
Do not leave tarpaulin installed on the dump truck where snow will
accumulate on the tarpaulin. This will cause the tarpaulin to become
stiff and unmanageable and may damage the tarpaulin.
Use tarpaulin to keep loads dry. Wet loads may stick, making dumping difficult.
OPERATION IN COLD WEATHER
NOTE
Keep in mind that oil must be circulated through the pilot valve and
cylinder before dump truck can be operated.
Cold weather presents special problems because cold oil and hydraulic components should be warmed up
before dump truck can be operated. This can be accomplished by performing the following steps:
1. Start engine and engage PTO (TM 9-2320-273-10) while engine is warming up. Idle speed should not
exceed 11001200 rpm.
2. Clear all personnel from around dump body.
3. Squeeze hydraulic control lever head together, refer to Figure 1 and check operation of body at low
engine rpm to verify reasonably normal operation.
4. Lower dump body, release T-handle, and place control lever in N (neutral) position.
