DO NOT attempt to dump in high wind. High winds may disperse aggregate, caus- ing injury to personnel or damage to equipment. High winds may also cause dump truck to roll over when bed is raised. Failure to follow this warning could result in death or injury to personnel or damage to equipment. In moderate winds use cargo cover to keep material from blowing out of dump bed. 2-17. OPERATION IN RAINY OR SNOWY WEATHER. a. In rainy or snowy weather use cargo cover to keep loads dry. Wet loads may stick, making dump- ing difficult. DO NOT leave cargo cover extended over an empty dump body. DO NOT attempt to uncover load without first removing any snow or water that has accumulated on cargo cover. Cargo cover may be damaged if this caution is not followed. b. Remove any accumulated snow or water from cargo cover before attempting to uncover load 2-18. OPERATION IN COLD WEATHER. Cold weather presents special problems because cold oil and hydraulic components should not be oper- ated to capacity until the system has warmed up. This can be accomplished by performing the following steps: a. Engage PTO (TM 9-2320-363-10) while engine is warming up. Run engine at idle speed. b. Clear all personnel from around the dump body. c. Operate hydraulic control lever and check operation of dump body at low engine rpms to verify normal operation (paragraph 2-10). Keep in mind that oil has not been circulated through the hydraulic cylinder. d. Lower dump body and place hydraulic control lever in N (Neutral) position (paragraph 2-10). 2-39/(2-40 Blank)
