A03020 General Safety and Operating Instructions A3-27
4. Pull the lever to
the rear to actu-
ate hoist circuit.
(Releasing the
lever any-
where during
"hoist up" will
place the body
in "hold" at that
position.)
5. Raise engine RPM to accelerate hoist speed.
Refer to the WARNING below.
If dumping very large rocks or sticky material as
described in WARNING above, slowly accelerate
engine RPM to raise body. When the material
starts to move, release hoist lever to "HOLD"
position. If material does not continue moving
and clear body, repeat this procedure until mate-
rial has cleared body.
6. Reduce engine RPM as last stage of hoist cylin-
der begins to extend and let engine go to low
idle as last stage reaches half-extension.
7. Release hoist lever as last stage of hoist cylin-
der reaches full extension.
To Lower Body
(When dumping over a berm or into a crusher):
8. Move hoist lever forward to "down" position and
release. Releasing the lever places hoist control
valve in the "float" position allowing the body to
return to frame.
NOTE: If dumped material builds
up at the rear of the body and the
body cannot be lowered, perform
steps "a" & "b" below:
a. Move hoist lever back to the "hoist" position
to fully raise the dump body. Then release
the hoist lever so it returns to the "hold" posi-
tion.
NOTE: DO NOT drive forward if the tail of body will
not clear the crusher wall in the fully raised position.
b. Shift Selector Switch to "Forward", release
Brake Lock, depress Override button and
drive forward to clear the material. Stop, shift
Selector Switch to "Neutral", apply Brake
Lock and lower body again.
NOTE: Failure to "hoist" the body after making an
unsuccessful attempt at lowering the body may result
in the dump body suddenly lowering after the truck
has pulled ahead of the material that was previously
preventing the body from lowering.
CAUTION! The truck is not to be moved with the
dump body raised except for emergency moves
only. Failure to lower body before moving truck
may cause damage to hoist cylinders, frame and/
or body hinge pins.
To Lower Body
(When dumping on flat ground):
It is very likely when dumping on flat ground that the
dumped material will build up enough to prevent the
body from lowering. In this case, the truck will have to
be driven forward a short distance (just enough to
clear the material) before the body can be lowered.
a. Shift Selector Switch to "Forward", release
Brake Lock, depress Override button and
drive just far enough forward for body to
clear material. Stop, shift Selector Switch to
"Neutral", apply Brake Lock.
b. Move hoist lever forward to "down" position
and release. Releasing the lever places hoist
control valve in the "float" position allowing
the body to return to frame.
NOTE: If dumped material builds
up at the rear of the body and the
body cannot be lowered, then
perform steps "c" and "d" below:
