DUMP BODY OPERATING INSTRUCTIONS
To operate dump body, proceed in the following manner: Bring vehicle to halt, set brakes, put main transmission
into first or any drive gear. Switch dash PTO lever to on position red light will indicate in gear. Move main
transmission shift lever to neutral. Hoist is now ready to be operated. Lift safety latch, located along side of pump
valve lever, move pump valve lever to raise position. Main valve is spring loaded, and must be held in raise or
lower position; if released will return to a hold or neutral position. When unit reaches it's maximum dump angle, it
will automatically pull the control valve to a neutral position.
It is suggested that unit be operated not to exceed 1500 engine rpm's. If you desire to spread or move when
dumping, proceed same as outlined above. Move transmission lever to first gear only, and proceed as slowly as
possible, not to exceed the 1500 engine rpm's.
OPERATION OF AIR BLEEDER VALVE (use only when needed)
Located at top of cylinder is an air bleeder valve. With body raised to raise position, and with safety props put into
sockets, bleeder valve may then be opened to bleed off air in hydraulic system. It is suggested that you use a
pair of hand pliers to open and close thumb pet cock. Due to the vibration of diesel engine, if this is tightened with
bare hands, it sometimes has a tendency to vibrate open, causing an oil leakage. It is, therefore, suggested that
pet cock be snugged with pliers. Use hydraulic oil (Gulf 562 or approved equal). When you check hydraulic oil,
the sight gauge should have approximately one to two inches of oil showing when hoist is in raised position.
When hoist is in down or lower position, sight gauge should show full.
