Operation
The dump bed is operated hydraulically through two
push button switches.
The actual location of these switches will vary
depending on the type of dump bed. The switches are
typically located at the rear of the vehicle on the left or
right side. An illustration of a typical switch assembly
is show to the right.
•
Press and hold the top button to raise the bed.
•
Press and hold the bottom button to lower the
bed.
The bed should remain in the raised position when
the ‘UP’ button is released. If the bed does not hold its
position, then the hydraulic system should be serviced
by a qualified technician.
The bed should be fully lowered within 3 to 15 seconds while the ‘DOWN’ button is pressed. If
the bed does not lower, or lowers very slow, then the hydraulic system should be serviced by a
qualified technician.
Lowering the Dump Manually
There is a manually operated valve located on the
side of the hydraulic pump assembly (see illustration).
This valve should only be used if the dump fails to
lower by pressing the lowering button. The valve is
covered by an Allen screw. Remove the Allen screw
to access the valve then turn the internal screw
clockwise to lower the dump.
If the dump fails to reach is fully raised position, then
it may be low on hydraulic fluid. Refer inspection and
servicing of the hydraulic system to a qualified technician.
Note: Overfilling will result in fluid exiting the fill port when the bed is lowered.
Do not place any body part underneath
a raised bed unless the bed prop rod
is in place. Severe bodily injury will
result if the bed lowers unexpectedly.
WARNING
Do not place any body part underneath a raised bed unless the bed prop rod
is in place. Severe bodily injury will result if the bed lowers unexpectedly.
