ADJUSTING RELEASE DEVICE
On the draw-bar of this pallet truck, you can
find the control handle which can be adjusted
in three positions:
1. Raise: handle down
2. Drive: handle in center position
3. 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:
1. If the forks elevate while pumping in the
DRIVE position, turn the adjusting nut on the
adjusting bolt or screw clockwise until pump-
ing action does not raise the forks and the
DRIVE position functions properly.
2. If the forks descend while pumping in the
DRIVE position, turn the nut or screw counter-
clockwise until the forks do not lower.
3. If the forks do not descent when the control
handle is in the LOWER position, turn the
nut or screw clockwise until raising the con-
trol handle lowers the forks. Then check the
DRIVE position according to item 1 and 2 to
be sure the nut and screw is in the proper
position.
4. 3.4 If the forks do not elevate while pumping
in the RAISE position, turn the nut or screw
counter-clockwise until the forks elevate
while pumping in the RAISE position. Then
check the LOWER and DRIVE position accord-
ing to item 1, 2 and item 3.

MAINTENANCE

The pallet truck is largely maintenance-free.
1. OIL: Please check the oil level every six
months. The oil can be hydraulic oil: ISO
VG32, its viscosity should be 30cSt at 400 C,
total volume is about 0.4lt.
Fig.3
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 on
the LOWER position, then move the draw-bar
up and down for several times.
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 posi-
tion when the job is over.
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.
