2.1Remove the handle component (H100), insert it into the pump shell (B101).
2.2Remove the axle from plastic bag(B09)
2.3Insert the axle (B09) at one end of the pump shell(B101), then pump shell (B101) and handle components (H100)
connection. Please note axle (B09) the position of the hole, Let the steel wire and nut on the chain (H09) through the axle
(B09) hole (See the hydraulic system diagram and the handle component diagram).
2.4Spring pin (B10) fixed the axle(B09).
2.5Handle (H01) press the pump plunger(B18), and remove the pin(B11).

3. TO ADJUST RELEASE DEVICE
On the handle of the pallet truck, you will find the control lever (H01) which can be set in three positions (See Fig. 1):
LOWER=to lower the forks; NEUTRAL=to move the load; ASCENT=to raise the forks. After assembling the handle, you can
adjust the three positions.
3.1 First tighten the setting screw (B46) on the crank link (B48) until the LOWER position function works.
3.2 If the forks elevate while pumping in the NEUTRAL position, turn the setting screw (B48) clockwise until pumping the
handle does not raise the forks andthe NEUTRAL position functions correctly.
3.3 If the forks descend while pumping in the NEUTRAL position, turn the setting screw (B48) counter-clockwise until the
forks do not lower.
3.4 If the forks do not descend when the control lever (H01) is in the LOWER position, turn the setting screw (B48)
clockwise until raising the control lever (H01) lowers the forks. Then check the NEUTRAL position as per item 4.2 and
4.3.
3.5 If the forks do not lift while pumping in the ASCENT position, turn the setting screw (B48) counter-clockwise until the
forks elevate while pumping in the ASCENT position. Then check the NEUTRAL and LOWER position as per item 4.2,
4.3 and 4.4.
4. MAINTENANCE
4.1 OIL
Please check the oil level every six months. Total oil amount is about 260 ml, add injection oil 50-100 ml, this must be
with the forks in the lowered position.
Add or change the hydraulic oil according to the table below.

4.2 HOW TO EXPEL AIR FROM THE PUMP UNIT
Air may enter the unit when the seals are replaced. Lift the control lever (H01) to 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 and tear of the unit. Pay special attention to the wheels, the axles, the
handle, the forks and lift and lower control.
4.4 LUBRICATION
Use motor oil or grease to lubricate all moveable parts.

5.8 Do not subject to unbalanced load, either side to side or along the length of the frame (refer to Fig. 2/B).
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 (refer to Fig. 2)
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 At other specific conditions or places, the operator should operate the pallet truck carefully.

7.1 Put the control lever in the LOWER position and lower the truck to lowest position.
7.2 Press the ON key to turn the system on. After the start-up sequence the indicator will display the weight.
7.3 Weighing method for gross weight:
Press the ZERO key to set the gross weight to 0. Put the forks under the pallet and check that the load is properly
balanced. Put the control lever in the ASCENT position, pump the handle to make the forks rise until the pallet has
left the ground. When the indicator is stable, the gross weight of the goods (total weight of the pallet and the goods)
is shown.
7.4 Weighing method for net weight:
To d is p l a y t h e w e i g h t o f t h e goods without the weight of the pallet (or another container):
7.4.1 Weigh single standard pallet, for example: weight of pallet: 40kg.
7.4.2 Press the TARE key, the indicator will display “0kg”.
7.4.3 Remove the pallet from the forks, the indicator will display “-40kg”.
7.4.4 Weigh the goods on the pallet as shown in 7.3, when the indicator is stable, the net weight of the goods is shown.
7.5 Switch between kg and lb.
Keep pressing FN key to switch the kg/lb unit (for LED version: keep pressing * key to exchange the kg/lb unit).
7.6 Turn off the I ndicator
Press on the OFF key to turn off the indicator
8. BATTERY POWER DATA AND REPLACEMENT
8.1 How to change batteries:
8.1.1 Loosen the screws of the indicator case and open it.
