ASSEMBLY

Your new pallet truck is delivered with the operating handle removed. To fit the
operating handle proceed as follows;

The numbers in brackets refer to the diagram on page 12.

1. Remove the split pin. (74) from the
shaft, (23) and keep safe for use
later.

2. Remove the shaft from the pump
body.

3. Insert the operating handle (8)
(with the warning label
underneath and the trigger on
the R/H side) between the side
ears of the pump body as shown.

4. Connect the operating handle to
the pump body by sliding the
shaft back through the fitting
holes in the pump body and the
operating handle.

NOTE: The handle needs to be held at an angle of approx 45º in order to

fit the shaft.

5. Turn the shaft so that the central hole is vertical. DO NOT push fully home
yet.

6. Pass the chain, (10), through the
centre hole in the shaft, Locate
the securing nut on the end of the
chain into the slot of the adjusting
lever, (52).

7. Turn the shaft so that the roll pin
lines up with the slot in the pump
body. Push the shaft fully home
and refit the split pin removed
earlier. This secures the handle in
place.

8. Push the handle down to a
horizontal position and withdraw
the travel pin (used to retain the
spring) from its hole in the pump
body.

• Store the pin in a safe place for

use should the pallet truck
need to be dismantled again.

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.

Raise the forks by pushing the control lever down until it latches, then pump
the handle backwards and forwards.

• The forks should lift and should remain in the up position.

If the forks drop, without raising the lever up to the lowering position, proceed
as follows:

1. Loosen the locknut A, Fig 6 (53)
and turn the screw B (54)
anticlockwise one full turn and
tighten the locknut.

2. Repeat steps 1 & 2 again if the
forks continue to drop. Turn the
screw another full turn and keep
repeating this procedure until the
forks stay up until the trigger is
operated to lower the truck. If the
forks do not lower when operating
the trigger, turn the screw clockwise, test and repeat until it does.

3. If the forks rise while pumping in the TRANSPORT position, release the
locking nut (A) and turn the adjusting screw (B) clockwise until the
pumping action does not raise the forks and they remain in position in the
TRANSPORT position.

4. If the forks descend while pumping in the TRANSPORT position, turn the
adjusting screw (B) anti-clockwise until the forks do not lower.

5. If the forks do not descend when the control handle is in the LOWER
position, turn the adjusting screw (B) clockwise until raising the control
handle lowers the forks. Check it’s operation in the TRANSPORT position.

6. If the forks do not elevate while pumping in the LIFT position, turn the
adjusting screw (B) anti-clockwise until the forks raise while pumping in the
LIFT position. Finally check the operation in the LOWER and TRANSPORT
positions.

7. When satisfied that the truck is lifting correctly, tighten the locknut item A,
Fig 6.

OPERATING INSTRUCTIONS

When first using the truck for the first time, familiarise yourself with the controls,
i.e. raise and lower the forks without any load, practice steering the empty
truck so as to be familiar how the truck reacts.

DAILY INSPECTION

Daily inspection is effective to find any malfunction or fault on the pallet truck.

WARNING: BEFORE OPERATING THE TRUCK, ENSURE YOU HAVE READ AND
UNDERSTOOD THE INSTRUCTIONS IN THIS MANUAL, PAYING PARTICULAR
ATTENTION TO THE SAFETY PRECAUTIONS. DO NOT USE THE PALLET TRUCK
IF ANY MALFUNCTION OR DEFECT IS FOUND.

1. Check the following points before operation.

• Visually check for structural deformation or cracks and listen for any

unusual noise or binding of the lifting mechanism.

• Check if there is any oil leakage.

PARKING

When parking the pallet truck, lower the forks to the lowest position and park
on smooth, even level ground where it is not an obstruction.

Chock the wheels if necessary to prevent the truck moving accidentally.

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.

• Make visual checks to ensure the load is secure and will not topple off

when lifted, also check the pallet is not broken etc.

• DO NOT OVERLOAD THE PALLET TRUCK!

4. Once the load has lifted sufficiently, put the trigger into the central position
(neutral) before moving the truck.

MOVING

Move the truck by pushing or pulling the handle assembly.

• Do not operate the truck on a slope.

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

• Make sure that the load is stable.

• If the pallet truck is moving, do not turn the handle at a right angle to

stop the pallet truck.

LOWERING

Before lowering the load, ensure it is clear to do so, making sure that nobody’s
feet, including your own are underneath the pallet etc

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

• By releasing the lever, the lowering movement will stop.

Ensure there is adequate clearance behind you, then withdraw the pallet
truck from the load.

• The forks will drop much faster when a loaded and the heavier the load

the faster still the rate of descent.

MALFUNCTIONS

If there are any malfunctions, stop using the pallet truck until it is repaired.

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.

MAINTENANCE

Whilst the pallet truck requires very little maintenance, the following care will
be beneficial.

DAILY/BEFORE USE

Inspect the pallet truck for signs of damage, distortion of components,

damage to castors etc.

OCCASIONALLY

1. Check the action of the hydraulic ram and inspect for leaks. If leaks are
apparent, DO NOT USE THE TRUCK, but send for repair to your Clarke
dealer). Always make every effort to contain any escape of oil and
prevent ingress into the local water course.

• Be aware that oil leaks can produce hazardous environmental

conditions. All leaks must be cleaned immediately and sand/sawdust or
similar absorbent material should cover the contaminated area (which
should be isolated), until it is completely cleaned and dried.

2. The hydraulic system may be topped up with any commonly available
hydraulic oil such as Clarke hydraulic oil (part number 3050830).

3. Remove any corrosion and repaint for protection.

4. Check the piston rod periodically for signs of corrosion. Clean any exposed
areas with a clean oiled cloth.

5. Ensure that labels and warning notices are in place and legible.

Parts & Service: 020 8988 7400 / E-mail: [e-mail] or [e-mail]

6. Inspect for security of all nuts and bolts.

7. Keep all moving parts lightly lubricated to prevent corrosion.

CHECKING THE OIL

1. Check the oil level every six
months if in regular use, by
topping up if necessary at the filler
plug.

• The capacity is approximately

0.3 litre.

• The recommended type is L-

HV46 Hydraulic oil, provided
the truck is not to be used
outside the temperature range
of -20°C to +40°C.

• In the case of a persistent oil leak which requires the dismantling of the

hydraulic parts to correct, the lift table should be taken to your Clarke
dealer for overhaul.

STORAGE

• Store in a dry place with the ram fully lowered to minimise ram (piston)

corrosion. If stored for long periods, inspect at least once a year, clean
and re-oil. For servicing, contact your CLARKE dealer, or CLARKE
International Service Department.
