DUMP BED (OPTIONAL)
There are numerous variations of the dump bed options that are available for the Model B series vehicles. Although
the physical design of the dump bed varies, the operation is basically the same. Refer to the original vehicle sales
order for specific information regarding the dump bed option used.
NOTE: The dump bed option must be installed at the factory; field kits are not available.

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.
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 will be located at
the rear of the vehicle on the left or right side.
Press the top button to raise the bed. The bed should
remain in the raised position when the button is released.
If the bed does not hold its position, then the hydraulic
system should be serviced.
Press the bottom button to lower the bed. The bed should
come down within 3 to 15 seconds. If the bed does not
lower, or lowers slowly then the hydraulic system should
be serviced.
Service
Service should only be performed by qualified
technicians familiar with hydraulic systems.
If the lowering rate of the dump bed has deminished, it
may be a result of a clogged filter or plugged restricted
flow fitting. The filter is internal of the pump and the
pump must be disassembled to clean the filter (item #
18 on the exploded part diagram). The restricted flow
fitting is installed at the cylinder, the hydraulic hose is
attached to this fitting. Remove the hose and fitting to
make sure nothing has plugged the hole in the fitting.
There is an internal high pressure relief valve in the pump.
This valve must be readjusted whenever the pump is
disassembled. To adjust the valve:
1. Raise the dump to its fully extended position and
tie or block it in place.
2. Press the lowering button to relieve back pressure.
3. Install a pressure gauge (3,000 pound) in line with
the high pressure hose to the cylinder.
4. Press the raise button and read the maximum
pressure on the gauge. Maximum pressure should
be approximately 2,000 pounds. Adjust the relief
valve as required.
Before operating the dump bed, place the forward/reverse switch in the center (OFF) position, turn
the key switch OFF and set the parking brake.
Do not operate the dump bed while parked sideways across a grade.
Do not operate the vehicle unless the dump bed is in its fully lowered position.
Failure to comply with these restrictions could result in severe bodily injury and/or property damage.
Before operating the dump bed, confirm that
there is enough vertical clearance above the
vehicle.
The restricted flow fitting controls the lowering
rate of the dump. Do not modify the restricted
flow fitting or remove it from the system as
this will result in rapid falling of the dump and
may cause severe bodily injury and/or property
damage.
Do not operate the dump bed while underneath
electrical wires. Contact with electrical wires
may result in serious injury or death.
