SAFETY PRECAUTIONS
1. Keep the work area tidy & well lit and keep children and bystanders away
from the work area.
2. Never carry out any alterations or modifications to the pallet truck.
3. Do not exceed the stated capacity of the truck. Refer to the technical
specifications above and the labelling on the truck. Overloading may
cause the truck to fail.
4. Load the truck evenly with the centre of gravity of the load over the
centre of the forks. Never stand on the forks.
5. Do not use on rough terrain. The pallet truck is designed for use on smooth
flooring only. Do not bounce the truck over rough ground, or down curbs
etc. Use ramps wherever possible.
6. Do not move unstable or loosely stacked loads. Use special care when
moving long, tall or wide loads or transporting a load which may impair
your view.
7. Never position any part of your body under the lifting mechanism or under
the forks. Do not transport passengers on the truck.
8. Do not operate a pallet truck until you have checked its condition, giving
special attention to the wheels, handle, forks and lift/lower controls.
9. Never use the pallet truck on a gradient if the load is too heavy to be
easily handled by the operator. The truck should not be used by operators
who are not physically capable of handling the loaded pallet truck.
10. Do not use if wheels or castors are damaged. Have them replaced
immediately.
11. When not in use, always ensure the truck is left where it is not hazard to
others. Never leave the truck on a gradient without first securely chocking
the wheels.
Please keep these instructions in a safe place for future reference.

ASSEMBLY
After unpacking, it is necessary to attach the truck handle assembly as
follows. (Part numbers refer to the list/diagrams on pages 10-13).
1. Take the handle assembly and lower the
end of the chain ‘A’, through the hole in the
pump body, so that it emerges at the
bottom of the housing.
2. Secure the truck handle to the base bracket
with the three socket-headed screws, ‘B’ ,
as in Fig 1, tightening them with the
hexagon key provided.
3. Release the screw adjuster (154) in Fig
4, in order to raise the end of the
forked lever, shown at ‘C’, Fig. 2, and
slide the threaded rod/locknut
attached to the end of the chain, ‘A’
between the forks, so that the locknut,
screwed on to the threaded rod,
locates behind the claws on the
underside of the forks. Release the
forked lever and screw the adjuster
(154) back in to remove any slack
from the mechanism.
Your pallet truck is now fully assembled, however, before use it is IMPORTANT
to check the following adjustments.

ADJUSTMENT
The control lever has three positions
shown in Fig 3 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.
Fig. 3
1. Set the control lever to its
lowest position (i.e. Lever in its
LIFT position).
2. 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.
3. If the forks descend while
pumping in the TRANSPORT
position, turn the adjusting screw (154) anti-clockwise until the forks do not
lower.
4. 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.
5. 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.

OPERATION
Before using the pallet truck always read the safety instructions in this manual
and the labelling on the product. The rated capacity of the truck assumes an
evenly distributed load with it’s centre being at the halfway point along the
length of the forks.
With the forks in the lowest position, manoeuvre the truck so that it is adjacent
to the pallet. Ensure the length of the forks match the length of the pallet.
Always position the pallet truck carefully, ensuring the load is centred about
the forks and is completely stable. Ensure there is no obstruction before raising
the load, or that the load cannot foul the truck mechanism when raised.
Lower the forks to the lowest height when the truck is not being used.
When lowering the truck with the forks loaded, pull the control lever up
carefully and gradually so that the load descends under complete control.

MAINTENANCE
Whilst the pallet truck requires very little maintenance, the following care can
be expected.
DAILY CHECK
Before use, check that there are no foreign bodies such as threads or rag to
jam the wheels. Always leave the forks in the lowered position when work is
over for the day.
CHECKING THE OIL
Check the oil level every six months by topping up if necessary at the filler
plug (144). The capacity is approximately 0.3 litres. 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.
BLEEDING AIR FROM THE PUMP UNIT
If the pallet truck has to be transported over any distance or been
overturned at any time, air may have permeated the hydraulic oil. This will
make it impossible to raise the forks under any load when pumping.
To bleed off the air, move the control handle (308) to the lower position, then
move the handle (310) up and down several times.
GREASING
Moving parts can be lubricated with motor oil or grease. After prolonged use,
the pivoting action of the steering wheel assembly may become stiff. In this
case, a shot of grease via the grease nipples (118 and 202) will restore
smooth movement.
