DIGITAL SCALE HYDRAULIC PALLET TRUCK

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 push-
ing 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.
WARNING!
• Read and understand the entire operator’s manual before using the pallet truck.
• Don’t load pallet truck beyond rated capacity of 4,400 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.
*** 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, break-
age 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 NEU-
TRAL 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.
Using a 5 mm hex key, remove the three
bolts on the base of the pallet truck
Feed the plug through the base of the
display box.
*** 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.

Align the display box with the holes on
the base. Screw in the bolts to secure
the two parts.
Using the screwdriver provided with the
pallet truck, tighten the screws on either
side of the plugs.
Turn on to test the scale.
Connect the two plugs.
Gently push and slide the battery cover to open it. To
connect the battery, plug the connector into the socket
to the right of the battery pack.

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).

MAINTENANCE
LUBRICATION
Your KLETON pallet truck is equipped with grease fittings in order to facilitate greasing its bearings.
It is recommended to apply grease every 6 months.
Adding Oil (if required)
1. Lower the pallet truck forks to their lowest point using the up/down lever on the handle. You will notice that the piston is now completely inside the pump assembly.
2. Remove the oil reservoir plug (part #20 of the pump assembly).
3. Using an oil can, add the hydraulic oil. The oil level should be up to the bottom of the hydraulic oil reservoir’s fill hole.
4. Re-insert the oil reservoir plug (part #20 of the pump assembly).
5. Pull the lever on the handle upwards to put it in the DOWN position (see page 3 for details).
Then, pump the handle up and down a minimum of 10 times in order to remove any air bubbles in the system.
Note: Unless the pump is leaking, you should not have to add any additional oil. Please contact your KLETON distributor if your pallet truck is leaking.

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.
