SAFETY INSTRUCTIONS

WARNING: THE TRUCK HAS TO BE USED ON SUBSTANTIALLY FIRM,
SMOOTH, LEVEL AND PREPARED SURFACES. THE LOAD MUST BE PLACED
CENTRALLY ON THE FORKS.

The operator should read all warning signs and instructions here and on the
pallet truck before use.

1. Examine the condition of the pallet truck before use, with particular
attention to the wheels, handle, forks and lift/lower controls. DO NOT use
the pallet truck if any defects are found.

2. DO NOT operate a hand pallet truck unless you are familiar with it and
have been trained or authorized to do so.

3. DO NOT make any changes or modifications to the pallet truck.

4. DO NOT use if the wheels or rollers are damaged. Have them replaced
immediately.

5. Keep the work area tidy and well lit.

6. Keep children and bystanders away from the work area.

7. DO NOT exceed the capacity of the pallet truck. Refer to the labelling on
the pallet truck and the Product Specification section in this manual,

8. DO NOT use on rough terrain. The pallet truck is designed for use on smooth
flooring only.

9. DO NOT use the pallet truck on a gradient if the load is too heavy to be
easily handled by the operator. The pallet truck must not be used by
anyone not capable of handling the full weight of the truck when loaded.

10. Watch for differences in the floor levels when moving the truck. The load
may overbalance or the truck could become uncontrollable.

11. DO NOT let the pallet truck come into direct contact with food.

12. DO NOT use the truck in explosive atmospheres.

13. The operator must wear safety shoes and gloves.

14. DO NOT allow personnel other than the operator to stand in front of or
behind the truck when it is moving or lifting/lowering.

15. DO NOT put your foot in front of rolling wheels. Injury could result.

16. DO NOT use the pallet truck as a jack.

17. Ensure nothing is beneath the pallet truck forks prior to lowering, especially
anyone’s feet.

18. Load the pallet truck evenly with the centre of gravity of the load above
the centre of the forks. DO NOT move unstable or loosely stacked loads.
Use extra care when moving long, tall or wide loads which impair your
view.

19. Keep watching the load and stop if the load becomes unstable.

20. When not in use, always make sure that the truck is stored where it is not a
danger to others. DO NOT leave the truck on a gradient without first
securely chocking the wheels.

21. Carry out maintenance work according to the “Troubleshooting” on
page 10.

22. This truck is not designed to be water resistant, therefore use it in a dry
environment.

ASSEMBLY

After unpacking it is necessary to attach the handle assembly as follows:

1. Withdraw the hinge pin (1) from
the truck frame.

2. Take the handle assembly and
lower the end of the chain
through the hole in the pump
body so that it emerges at the
bottom of the housing.

3. Insert the hinge pin through the
handle and frame to connect the
handle to the truck and secure
the hinge with the cotter pins at
each end.

4. Take the end of the chain and
lead it past the hinge pin and
engage it with the actuating lever
(6).

5. Move the handle assembly to the
level position and remove the

ADJUSTMENT

The control lever has three positions
shown and indicated by the label on
the handle.

• With the lever pulled to the

upper position, the forks will
lower.

• The middle position allows the

load to be transported.

• The lower position will cause

the forks to lift when the handle is pumped.

The screw (9) is used to adjust the
range of movement of the handle
relative to the hydraulic pump.

Raise and lower the handle to make
the forks lift up.

1. If the truck drops immediately
after it is raised, turn the screw (9)
in a counter-clockwise direction
Test again to see if the truck lifts
normally.

2. If the truck fails to lower after being raised, turn the screw clockwise.

The locking nut (8) is used to secure the mechanism once the correct setting is
achieved.

OPERATING INSTRUCTIONS

BEFORE USE

Daily inspection is advisable to find any defect of the pallet truck. Check the
following points before operation.

• Visually check for structural damage and listen for any unusual noise or

binding of the lifting mechanism.

• Check if there is any oil leakage.

• Raise/lower the forks to check for vertical creep of the lifting

mechanism.

• Check for any damage to the wheels and ensure they rotate smoothly.

• Check that all the bolts and nuts are tight.

• Verify that all warning labels are in place.

WARNING: DO NOT USE THE PALLET TRUCK IF ANY DEFECT IS FOUND.

LIFTING

1. Check that the load does not exceed the rated capacity of the truck.

2. Roll the pallet truck with its forks slowly under the pallet/load until the back
end of the fork rests against the load.

3. Move the operating lever down to
the ‘Lifting’ position. Lift the load
by moving the handle assembly
up and down.

• The load must be evenly

distributed across both forks.

• DO NOT OVERLOAD.

MOVING

1. Ensure the control lever is in its middle (transport) position.

2. Move the truck using the handle assembly.

3. DO NOT operate the truck on a slope.

4. Watch for differences in the floor level when moving the pallet truck.

5. Make sure that the load is stable.

6. If the pallet truck is moving, DO NOT turn the handle at a right angle to stop
the pallet truck.

LOWERING

1. Lower the load by moving the
operating lever up to the lowering
position carefully.

• By releasing the lever, the

lowering movement will stop.

2. Ensure there is adequate
clearance behind you when
withdrawing the forks from the
pallet.

3. DO NOT put your foot or hand under the lifting components.

PARKING

When parking the pallet truck, lower the forks to the lowest position and park
on smooth, level ground where it is not an obstruction. If the ground is not flat,
chock the wheels to stop it moving.

CARE & MAINTENANCE

Whilst the pallet truck requires very little maintenance, the following care can
be expected.

PURGING AIR FROM THE HYDRAULIC SYSTEM

If the pallet truck has been
transported over any distance or has
been overturned at any time, air may
have entered the hydraulic system.
This will make it impossible to raise the
forks under load.

1. Hold the control handle in the
‘lower’ position.

2. Move the handle up and down
several times.

CHECKING THE OIL

1. Check for any oil leaks and top up
if necessary at the filler plug.

• The capacity is approximately

0.22 litre.

• The recommended type is L-

Hydraulic 32 oil, provided the
truck is not to be used outside
the temperature range of -20°C
to +40°C.
