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 the handle.
 Remove the shaft (18). This will free the pump and handle
assembly from the pallet jack.
 Remove the oil plug (46), turn the pump over and empty
the oil into a suitable container. Pump the handle until all
the oil has drained. Dispose of used hydraulic oil
according to local disposal regulations.
 Pull out the plunger piston (40) and/or ram piston (42).
 Remove all O-rings and seals. See Fig. 6.
 Insert a 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
with 0.26L (8.8 oz.) of new hydraulic jack oil.
