OPERATION
TECHNICAL DATA
WARNING! Operator must read and understand
instructions here and on truck prior to use.
On the handle of the pallet truck, you will find the
control lever which can be set in three positions.
(See Figure 1)
- LOWER=to lower the forks
- NEUTRAL=to move the load
- RAISE=to raise the forks
1. If the forks elevate while pumping in the NEUTRAL
position, turn the setting screw clockwise until
pumping the handle does not raise the forks and
the NEUTRAL position functions correctly.
2. If the forks descend while pumping in the NEUTRAL
position, turn the setting screw counterclockwise
until the forks do not lower.
3. If the forks do not descend when the control lever is in
the LOWER position, turn the setting screw clockwise
until raising the control lever lowers the forks. Then
check the NEUTRAL position as per step 1 and 2.
4. If the forks do not lift while pumping in the RAISE
position, turn the setting screw counterclockwise
until the forks elevate while pumping in the RAISED
position. Then check the NEUTRAL and LOWER
position as per steps 1, 2 and 3.
NOTE: When viewing the truck from the handle
side, the setting screw is located on the right
side of the pump above the right wheel. The
truck will lower faster or slower depending on
how far in or out the screw is adjusted.

OIL
Check the oil level every six months. The oil capacity is
about 0.3L. Restore the fluid level in the reservoir to 5mm
below the top; this must be done with the forks in the
lowered position.
Use the hydraulic oil ISO-VG32 or equivalent. Oil viscosity
should be 30cSt at 104°.
HOW TO EXPEL AIR FROM THE PUMP UNIT
Air may enter the unit over time or when the seals are
replaced. To expel the air, lift the control lever to the
LOWER position and move the handle up and down
several times.
DAILY CHECK AND MAINTENANCE
Daily checks of the pallet truck can limit wear and tear
on the unit. Pay special attention to the wheels, the
axles, the handle, the forks and lift and lower control.
LUBRICATION
Use motor oil or grease to lubricate all moveable parts.
MAINTENANCE
SAFETY
NOTE: For safe operation of the Deluxe Pallet
Truck, read all warning signs and instructions
here and on the pallet truck prior to use.
1. Do not operate the truck unless you are familiar with
it and have been trained and authorized to do so.
2. Do not use the truck on sloping ground.
3. Never place any part of your body in the lifting
mechanism or under the forks or load. Do not carry
passengers.
4. We advise that operators wear gloves and safety
shoes.
5. Do not handle unstable or loosely stacked loads.
6. Do not overload the truck.
7. Always center loads on the forks, not at the end of
the forks. (See Figure 2)
8. The capacity of the truck assumes an evenly
distributed load with the center of the load being at
the halfway point of the length of the forks.
9. Make sure the length of the forks matches the length
of the pallet load.
10. Lower the forks to lowest height when the truck is not
being used.
