Maintenance Interval
Maintenance Point
Before and after operating
OIL. Check the oil level annually by removing the Oil Plug (70)
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 the pump housing
(Figure 7). Do not use any other type of oil. When finished,
replace the Oil Plug (70).

LUBRICATION. Wheel bearings are sealed and require no
lubrication. The crankshaft features "oil lite" bushings that also
require no lubrication.
Lightly oil all other moving parts.
BLEEDING THE AIR. There may be times when the forks do
not rise while pumping when in the "Lift" position. Most likely
this is because air has been introduced in to the hydraulic
system. The air can be removed by moving the control handle
to the "Lower" position, then pumping the handle up and down
several times. Repeat this process until the forks lift as
intended.
SEAL AND O-RING REPLACEMENT FOR RAM AND
PLUNGER PISTON
 Raise the pallet jack by pumping handle.
 Remove spring pin (22). This will free the pump and
handle assembly from the pallet jack.
 Remove the oil plug (70), 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.
 Pull out the plunger piston (82) and/or ram piston (72).
 Remove all O-rings and seals. See Fig. 8.
 Insert the 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 Fig. 8.
