Chapter 1 Introduction
Thank you for using our pallet truck. Your pallet truck is made of high quality steel and is
designed for the horizontal lifting and transport of loads on a pallet or standardized
containers on a level, fixed base. For your safety and correct operation, please carefully
read this instruction before using it.

Chapter 3 To Attach Draw-bar To Pump Unit
If you have purchased a wooden box of pallet truck, some assembly is required.
Certainly, you need some tools, a hammer, a pliers, a spanner, etc; and some parts, one
axle with hole (A105), two elastic pins (A106)(Note one is in the axle (A105)), these
parts are putted in a plastic bag, which is putted into the draw-bar.

Page 2 of 13
NOTE: The number of draw-bar and pump should be the same.
1. Draw-bar 2. Pin 3. Axle with hole 4. Elastic pin 5. Fork frame
Fig. 1
When attaching the handle, you had better squat just behind the pallet truck. Then you:
3.1 Insert the draw-bar onto the pump piston (A346), then use a hammer to insert the
axle with hole (A105) into the hydraulic pump and draw-bar from the right to left. (See
fig. 2 ).
3.2 Let control handle(A117) to the ‘LOWER’ position, then
pass the adjusting nut(A104), adjusting bolt(A103) and
chain(A102) through the hole of axle(A105) with your hand
(See fig. 3).

Page 3 of 13
3.3 Press the draw-bar (A110, A110B) down, take away the pin(#2) (See Fig. 1).
3.4 Let the control handle (A117) on ‘RAISE’ position, then raise the lever plate (A315)
with the pin (#2) and insert the adjusting bolt(A103) into the front slot of lever plate
(A315), note to keep the adjusting nut (A104) on the under side of the lever plate.
3.5 Use a hammer to tap another elastic pin (A106) into the axle with hole (A105).
The draw-bar is now assembled to the pump.
Chapter 4 To Adjust Release Device
On the draw-bar of this pallet truck, you can find the control handle(A117) which can be
regulated in three positions :
Raise -handle down
Drive position -handle in center position
Lower -handle up, the lever moves backthe drive position when released.
If however they have been changed, you can adjust according to following step:
4.1 If the forks elevate while pumping in the DRIVE position, turn the adjusting nut (A104)
on the adjusting bolt(A103) or screw(A318) clockwise until pumping action does not raise
the forks and the DRIVE position functions properly.
4.2 If the forks descend while pumping in the DRIVE position, turn the nut(A104) or
screw(A318) counter-clockwise until the forks do not lower.
4.3 If the forks do not descent when the control handle (A117) is in the LOWER position,
turn the nut(A104) or screw (A318) clockwise until raising the control handle(117) lowers
the forks. Then check the DRIVE position according to item 3.1 and 3.2 to be sure the
nut (A104) and screw(A318) is in the proper position.
4.4 If the forks do not elevate while pumping in the RAISE position, turn the nut (A104) or
screw (A318) counter-clockwise until the forks elevate while pumping in the RAISE
position. Then check the LOWER and DRIVE position according to item 3.1, 3.2 and
item 3.3.
Chapter 5 Maintenance
The pallet truck is largely maintenance-free.
5.1 OIL
Please check the oil level every six months. The oil can be hydraulic oil: ISO VG32, its
viscosity should be 30cSt at 400C, total volume is about 0.4lt.
5.2 TO BANISH THE AIR
The air may come into the hydraulic oil because of transportation or pump in upset
position. It can cause that the forks do not elevate while pumping in the RAISE position.
The air can been removed in the following way: let the control handle (A117) on the
LOWER position, then move the draw-bar up and down for several times.
5.3 DAILY CHECK AND MAINTENANCE

Page 4 of 13
Daily check of the pallet truck can limit wear as much as possible. Special attention
should be paid to the wheels, the axles, as thread, rags, etc. It may block the wheels.
The forks should be unloaded and lowered in the lowest position when the job is over.
5.4 LUBRICATION
All bearings and shafts are provided with long-life grease at the factory. You only need
provide with long-life grease at monthly intervals or after each time the truck is cleaned
thoroughly to the lubrication points.
Chapter 6 Guide To Safety Operation
6.1 Operator should read all warning signs and instructions here and on the pallet truck
before using this truck.
6.2 Do not use on a slopping ground.
6.3 Do not operate a pallet truck unless you are familiar with it and have been trained or
authorized to do so.
6.4 Do not operate a pallet truck unless you have checked its condition. Give special
attention to the wheels or rollers, the draw-bar unit, the fork unit, the lever plate, etc. .
6.5 To pull the truck, always move the control handle into the drive position. This makes
the draw-bar easier to move and depressurizes the pump section of the hydraulics. This
preserves the hydraulic seals and the valve components. A long service life can be
expected.
6.6 Do not take up any people on the pallet truck.
6.7 The operator had better take on gloves for labor protecting.
6.8 When the goods have been transported, all people should be away from the forks for
600mm.
6.9 Do not load goods like fig. 5/B .
6.10 Do not load over maximum capacity.
6.11 At others special condition or place, the operator should be carefully to operate the
pallettruck.
