INSPECTION BEFORE USE
If the hand pallet truck is not used for a long
time, air may get into the hydraulic system. Due
to this, the trouble can be eliminated by the fol-
lowing method:
Turn the hand knob to the drop position and
rock the handle for 4 to 6 times. Then release
the operation knob. If necessary, the process can
be repeated for several times until the hand pal-
let truck can be operated normally.
LOADING TYPE AND RATED WEIGHT
The ideal loading type is that the gravity center
of the cargo is just in the middle of the truck
forks. The rated weight must be reduced when
the cargo gravity center is not in the middle of
the truck forks. The rated weight is shown as the
label.
OIL
The oil capacity which oil pump needs is about
250ml (0.25kg). According to the ISO oil crite-
rion, the choice of oil is 32# when the environ-
ment temperature during -5~40ºC. The choice
of oil is low temperature oil when the environ-
ment temperature during -35~-5ºC
MAINTENANCE
The routine check should be carried out daily
and every abnormal phenomenon should be
dealt with immediately. Please do not use faulty
truck in order to prolong the service life.
If there are any faults, please consult the profes-
sional. If it is necessary to replace the parts, the
new parts should be provided by the original
manufacturer. All the rotary joints should renew
the motor oil every three months.
Pay special attention to the place between
wheel and axis. Make sure that there is not any
yarn or other rags in order to keep all wheels
running with handiness. After the maintenance
and upkeep, plase record in the list below:

LIFT HEIGHT
Hydraulic oil is not enough. Add appropriate
filtrated working oil.
THE FORKS CAN'T RETURN TO THE LOWEST PO-
SITION
Too much hydraulic oil. Take out appropriate
working oil
The rotary parts are deformed or blocked. The
trunk piston and guides bushing are blocked.
Replace the parts.
THE FORKS CAN'T DROP AFTER LIFTED.
There is something abnormal in the unloading

The surface of some parts is damaged or worn.
Replace the damaged parts.
The coupled places become loosened. Fasten
the loosened place again.
THE FORK CAN'T BE LIFTED.
The viscosity of the working oil is too high, or
there is no working oil. Replace the working oil.
There is impurity in the oil. Clear up the impuri-
ty and add new working oil.
There is something abnormal in the unloading
device. Readjust the unloading device.
WHEN THE HANDLE IS ROCKED, THE FORKS
DROP IMMEDIATELY AFTER THEY ARE LIFTED;
the handle returns or the forks drop markedly
after they are lifted.
The valve of oil pump is blocked by abnormal
matter. Open the valve and take out the parts.
