Section II. OPERATION UNDER UNUSUAL CONDITIONS
Operation in Windy Weather.
Do not attempt dumping rations in high or gusty winds.
In moderate winds, use the tarpaulin to keep material from blowing out of the dump bed. Be sure the tie-down straps are
in place to prevent flapping (fig. 2-).
Operation in Rainy or Snowy Weather.
Do not leave
r tarpaulin installed on the truck in conditions where snow w ill accumulate the
tarpaulin. is will cause the tarpaulin to become stiff and unmanageable, and could dame
Use the tarpaulin to keep the loads dry. Wet loads may stick, making dumping difficult.
Operation in Cold Weather.
Cold weather presents special problems because cold oil and hydraulic components should not be operated to capacity
until the system has been warmed up. This can be accomplished by performing the following steps:
Engage the PTO (TM 9-2320-273-10) while the engine is warming up. Idle speed should not exceed 1100-1200
Clear all personnel from around the dump body.
Squeeze the hydraulic control lever heed together (see fig. 2-5) and check operation of the body at low engine
RPMs to verify reasonably normal operation. Keep in mind that oil has not been circulated through the pilot valve
and hoist cylinder.
Lower the dump body, release the T-handle, and place the control lever in the N (neutral) position.
