2. To raise the fork, push control lever all the
way down, and pump the handle until the
desired fork height is reached.
3. To move the handle without affecting the
fork setting, set the control lever in the
center neutral position. The load can now be
pushed or pulled using the handle.
4. To lower the fork, pull lever all the way up.
Allow the load to descend slowly in a
controlled manner.
The lever is spring
loaded and will return to the neutral position
when released.
When not in use, do not allow
heavy loads to remain on the fork for an
extended period of time. Always lower fork
completely when not in use.
Up-Down Cam Adjustment
When pumping the handle with the lever in
neutral position, there should be no movement
of the fork. If there is fork movement, the cam
must be adjusted:
1. Place lever in neutral position.
2. Loosen the hex nut (16).
3. Adjust the socket head cap screw (17) while
pumping the handle, until there is no longer
any movement of the ram.
4. Tighten the hex nut (16).
Cleaning the Release Valve (Bleeding the
Pump)
Over time, the hydraulic pump may become
clogged with debris or air bubbles causing
improper function.
Clean the release valve as follows:
1. Pump handle quickly, raising pallet truck to
full extent. Pull lever all the way up in order
to lower the fork,
while continuing to pump
the handle.
2. When fork has lowered completely, the
valve has been flushed. Repeat if
necessary.
Maintenance
Check the oil level annually by removing the oil
plug (50) on top of the pump housing. When
changing or adding oil, fill the tank through the
oil plug hole to 80% capacity with hydraulic jack
oil, about 2-1/2” deep in pump housing. See
Figure 4. Do
not
use any other type of oil. When
finished, replace oil plug (50).
Figure 4
Wheel bearings are sealed and require no
lubrication. The crank shaft features “oil lite”
bushings that also require no lubrication.
Lightly oil all other moving parts.
Seal and O-Ring Replacement for
Ram and Plunger Piston
1. Raise the pallet truck by pumping handle.
2. Remove spring pin (82). This will free the
pump and handle assembly from the pallet
truck.
3. Remove the oil plug (50), turn pump over
and empty the oil into a suitable container.
Pump handle until all oil has drained.
Dispose of used hydraulic oil according to
local disposal regulations.
4. Pull out plunger piston (37) and/or ram
piston (48).
5. Remove all o-rings and seals. See Figure 5.
6. Insert new o-ring or seal one at a time
making sure to replace with the same size
that was removed.
Reassemble and fill the oil tank through the oil
plug hole to 80% capacity with new hydraulic
jack oil, about 2-1/2” deep in pump housing. See
Figure 4.
