Hydraulic Hand Pallet Truck
9008-08/29/079257-07/18/16

WARNING!
• Read and understand the entire operator’s manual before using the pallet truck.
• Don’t load pallet truck beyond rated capacity of 11,000 lbs.
• Secure load before transporting.
• Keep the load centered on the pallet.
• Don’t operate loaded pallet truck on ramps or inclines.
• Always wear appropriate safety shoes.
• Never leave a loaded pallet truck unattended in the raised position;
always lower load to the floor.
PALLET TRUCK ASSEMBLY
Note: Individual trucks are assembled and ready to use. Pallet trucks purchased in
crate quantities (6 units to a crate) require some assembly.
Tools needed for assembly: hammer, flat screwdriver, 14mm wrench
*** IMPORTANT - SAFETY ***
Verify that spring safety pin is in place.
The pin should be well rested in the
holes situated on each side of the pump
housing. If the safety pin is not rested
properly in one of the holes, put pres-
sure on the spring using a “C" clamp
pushing down on the pump stem. Once
pressure is relieved on the pin, reinsert
properly and remove clamp slowly,
To attach handle assembly to the frame:
If handle pin’s center hole is
facing away from you, insert pin
from other side.
*** IMPORTANT - FACT ***
The up/down lever’s chain
passes through this center hole.
If left this way, the chain will
have an “S" form and be under
too much tension, making the
up/down lever difficult to use
accurately.
1.
Insert handle pin without the
handle and verify that the center
hole is facing you.
3. 4.
Insert handle pin into cor-
responding holes and using a
hammer, drive in one spring pin
on one side only.
2.

*** IMPORTANT - CHAIN****
Before this step, make sure to
feed the chain on the outside
of the piston stem roller (see
yellow arrow). If left in its proper
position, it will not be possible to
insert the handle pin and chain,
breakage may occur.
Align handle holes with pump
housing holes and push through
handle pin (see red arrow)
Make sure that handle pin is
completely through the handle
and resting on the other side.
Pull down on the handle to
release the tension on the safety
pin. CAREFULLY remove the
safety pin.
Feed the chain and nut first back
inside the handle THROUGH the
handle pin’s center hole.
***IMPORTANT - TIP ***
Release the up/down lever to
its lowest position to make the
process easier.
Once the chain is in the proper
position, check to see that it
moves freely and that it is not
obstructed.
Using both hands,
push on the valve
cam to raise the
hook inside the
housing and feed
the end of the
chain in the cam.
(see image at
right)
Pump the lever a few times to
raise the forks. Put the up/down
lever to its NEUTRAL position.
Using a 14mm wrench and a
flat screwdriver, adjust the valve
cam so that the forks don’t lower
or rise (if handle is pumped) at
this position.
*** IMPORTANT - FINAL CHECK ***
Test all the features of the pallet
truck before this step. The handle
should be pumped with full strokes
to prime and eliminate air in the
system. The up/down lever should be
checked at the handle’s lowest posi-
tion for this puts the most tension
on the chain. Once the pallet truck is
adjusted properly and is performing
well, drive in the second spring pin
using a hammer.

OPERATING PALLET TRUCK
To raise the forks, place handle lever in UP position (bottom part of the handle slot).
See Figure 2.
Figure 2
To lower forks, pull lever to DOWN position (upper part of the slot).
To freely move the handle, set the lever in NEUTRAL (center notch of the slot).
To lift a load:
1. Lower forks to lowest position.
2. Insert forks under load or into pallet.
3. Place lever in UP position (bottom part of the slot).
4. Move handles up and down until forks reach desired height.
To move a load:
1. Place lever in NEUTRAL position (center notch of the slot).
2. Pull or push to desired location.
To lower a load:
1. Pull lever to the DOWN position (upper part of the slot).
2. Pull forks away from load.

TROUBLESHOOTING
Possible problems could arise in the operation of your hydraulic pallet truck. Their probable cause(s) and
corrective action(s) follow:
Condition Probable Causes Corrective Action
Hydraulic unit does
not lift
Oil low in tank Make sure there is no till leakage from valve and add oil.
Relief valve not seated properly or air in the
system See “Cleaning Relief Valve" in this manual.
Defective pressure seal in main cylinder Consult authorized service centre.
Relief valve not adjusted properly Adjust valve by pressure adjustment screw
Once lifted truck
lowers by itself
Relief valve not seated properly See “Cleaning Relief Valve" in this manual.
Defective pressure seal in main cylinder Consult authorized service centre
Relief valve not adjusted properly Adjust valve by pressure adjustment screw
Oil leakage Consult authorized service centre
Fork does not lower
Cam chain broken Replace cam chain.
UP-DOWN cam nut out of adjustment Refer to “Adjusting UP-DOWN Cam" in this manual.
Broken fork rods and linkage Consult authorized service centre
Cam chain lock-nut fallen off Replace cam chain lock-nut
Lever does not set at
NEUTRAL position Relief valve not adjusted properly Adjust valve by pressure adjustment screw
Cleaning Relief Valve
Over time, relief valve may become clogged with debris and will not work properly.
To clean relief valve, flush the hydraulic system as follows:
Hold the UP/DOWN lever to the DOWN position and move the handles up and down several times.
Adjusting UP-DOWN Cam
DO NOT adjust the up/down
lever control using the lock
nut at the end of the handle
chain. If nylon locking threads
are removed from the screw
threads, rolling vibration will
cause the nut to unscrew and
fall off, leaving the up/down
lever unusable.
Use proper set screw
and lock nut adjustment
located on the side of the
pump. This feature was
designed to ease the pallet
truck adjustment.
Tools required are:
flat screwdriver and a
14mm wrench.
