2. OPERATING PROCEDURES
2.1. Assemble the indicator

2.2. Assemble the tiller and pump unit
2.2.1. Insert the draw-bar onto the pump piston (303),
then use a hammer to insert the axle with hole (G105)
into the hydraulic pump and draw bar from the right to the
left (see figure 1).
2.2.2. Put the control handle (G117) to the lower position,
then pass the adjusting nut (G104), adjusting bolt (G103)
and chain (G102) through the hole of the axle (G105)
with your hand.
2.2.3. Press the draw-bar (G110) down, take away the spring which fixes the Spring Cap
(301).
2.2.4. Put the control handle (G117) to then raise position, the raise the lever plate (319)
with the pin and insert the adjusting bolt (G103) into the front slot of the lever plate (319).
Note: keep the adjusting nut (G104) underneath the lever plate.
2.2.5. Use a hammer to tap another elastic pin (G106) into the axle with hole (G105).
The draw-bar is now assembled to the pump.
3. Adjust the release device
On the tiller grip of the truck, you can find the finger tip control handle lever (G117) with
three positions:
Lift Position - pull up the finger tip control
Neutral Position - place the finger tip control at center position
Lower Position- push down the finger tip control
The three positions of the finger tip control have been adjusted before delivery. If there
are some changes due to unexpected reasons, make adjustment according to the
following instructions:
3.1. Place the finger tip control (G117) in the Neutral Position and swing the tiller up
and down. At this time, the forks should neither go up nor go down. If:
A) the forks go up, turn the nut (G104) clockwise until the forks stop lifting.
B)the forks go down, turn the nut (G104) counterclockwise until the forks stop lowering.
3.2 Pull up the finger tip control (G117) in the Lift Position, and swing the tiller up and
down. At this time, the forks should lift steadily. If not, turn the nut (G104)
counterclockwise until it starts lifting, then repeat step 3.1.
3.3 Push down the finger tip control (G117) in the Lower Position. If the forks can not go
down. Turn the nut (G104) or screw (318) clockwise until the lifting control (G117)
can lower the forks. Then follow step 3.1 to check the neutral position to make sure
the nut (G104) and screw (318) are in place.

5. MAINTENANCE
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 40°C, total volume is about 0.4lt.
5.2 To remove air from the pump
Air may come into the hydraulic oil during transportation or if the pump has been
turned upside down. It can cause the forks not to elevate while pumping in the raise
position. The air can been removed in the following way: put the control handle (117)
to the lower position, then move the draw-bar up and down several times.
5.3 Daily check and maintenance
Daily check of the pallet truck with scale can limit wear as much as possible. Special
attention should be paid to the wheels, the axles, as thread, rags, etc. 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 add long-life grease at monthly intervals or after each time the lubrication points
of the truck are cleaned thoroughly.
