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 pres­sure 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 cor­responding 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 posi­tion 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.
