2. TO ATTACH HANDLE 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, two
elastic pins (Note one is in the axle), these parts are putted in a plastic bag, which is putted into
the draw-bar.
NOTE: The number of draw-bar and pump should be the same.

. 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:
2.1. Insert the draw-bar onto the pump piston (A),then use a hammer to insert the axle with
hole(K) into the hydraulic pump and draw-bar from the right to left. (See fig. 2 ).
2.2. Let control handle to the ‘LOWER’ position, then pass
the adjusting nut (G), adjusting bolt (F) and chain (E)
through the hole of axle(K) with your hand (See fig. 3)
2.3. Press the draw-bar (D) down, take away the pin(#2) (See Fig. 1).
2.4. Let the control handle on ‘RAISE’ position, then raise the lever plate (J) with the pin ( #2)
and insert the adjusting bolt(F) into the front slot of lever plate, note to keep the adjusting
nut (G) on the under side of the lever plate(J).
2.5 Use a hammer to tap another elastic pin into the axle with hole (K). The Draw-bar is now
assembled to the pump.

3. TO ADJUST RELEASE DEVICE
On the draw-bar of this pallet truck, you can find the control handle which can be regulated in three
positions :
Raise - handle down
Drive position - handle in center position
Lower - handle up, the lever moves back the drive position when released.
If however they have been changed, you can adjust according to following step:
3.1 If the forks elevate while pumping in the DRIVE position, turn the adjusting nut on the adjusting
bolt or adjusting screw clockwise until pumping action does not raise the forks and the DRIVE
position functions properly.
3.2 If the forks descend while pumping in the DRIVE position, turn the nut or adjusting screw
counter-clockwise until the forks do not lower.
3.3 If the forks do not descent when the control handle is in the LOWER position, turn the nut or
adjusting screw clockwise until raising the control handle lowers the forks. Then check the DRIVE
position according to item 3.1 and 3.2 to be sure the nut or adjusting screw is in the proper position.
3.4 If the forks do not elevate while pumping in the RAISE position, turn the nut or adjusting screw
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 3.3.

5. MAINTENANCE
Your pallet truck is largely maintenance-free.
4.1 Hydraulic Oil
Please check the oil level every six months. The oil capacity is about 0.3lt. Use the hydraulic type
oil according to temperature scale below.
Temperature
Oil
-20℃~+40℃
L-HV46 Hydraulic oil
4.2 HOW TO EXPEL AIR FROM THE PUMP UNIT
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 banished
in the following way: let the control handle on the LOWER position, then move the handle up and
down for several times.
4.3 DAILY CHECK AND MAINTENANCE
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.

4
4.4 LUBRICATION
Use motor oil or grease to lubricate all moveable parts.
6. GUIDE TO SAFETY OPERATION
For safe operation of the Hand Pallet Truck, please read all warning signs and instructions
here and on the pallet truck prior to use.
6.1 Do not operate the pallet truck unless you are familiar with it and have been trained or
authorized to do so.
6.2 Do not operate the truck unless you have been trained and authorized. Give special attention to
the wheels, the handle assembly, the forks, and the lower control.
5.3 Do not use the truck on sloping ground.

5.6 Do not handle unstable or loosely stacked loads.
5.7 Do not overload the truck.
5.8 Always place loads centrally across the forks and not at the end of the forks (See Fig. 2).
5.9 The capacity of the truck assumes an evenly distributed load with the centre of the load being
at the halfway point of the length of the forks.
5.10 Make sure that length of the forks matches the length of the pallet.
5.11 Lower the forks to lowest height when the truck is not being used.
5.12 In other specific conditions the operators should take extra care in operating the truck.

deformed resulting from partial loading
slanting to one side or over-loading.
- The fork was kept in the high position
for long time with piston rod bared to
arise in rusting and jamming of the rod.
- The adjusting nut or the screw is not
in the correct position.
