TOOLS
When lifting goods, insert the forks under the pallet of the goods, when necessary, break the back wheels and pull the hand lever. The pinch
roller presses the pump core to make the oil in the pump cylinder flow into the piston cylinder, in order to push the piston rod move upward
and lift the forks upward via a chain for a two times travel. Pull the hand lever back and forth so as to lift the goods and achieve the purpose
of lifting. When the forks are lifted to the maximum height, the pressurized oil flows back into the oil tank via an oil draining hole and in that
case, even the hand lever is pulled, the forks raise no more to avoid damaging components by impacting the top.
When handling heavy goods, the stacker is able to travel via manual pushing (pulling).
When unloading, pull the unloading hand lever, the oil return valve opens and with the effect of the dead weight of the heavy goods and
forks, the operational oil in the piston cylinder flows back into the oil tank through the oil return valve, and when the piston rod and the forks
decline to the lowest position, the goods are unloaded and the forks are withdrawn.
5 Operation and maintenance
•
The oil must be filtered and clean and ensure sufficient oil quantity.
• Before operation, inspection must be conducted for the stacker to ensure the stacker is in normal condition and there is no loose
component.
• The goods should be smoothly distributed on the forks and no overload is allowed.
• After the operation is completed, the goods should be unloaded and the heavy goods are not allowed to be on the forks for a long time.
• When lowering goods, the hand lever of the oil return valve should be operated slowly and gently to avoid sudden declination during
quick declination process which causes unsafe situation. When lowering the goods quickly, the oil return valve can not be closed
suddenly as inertial acceleration is generated during the process of quick declination. If that, a great force will be generated to damage
the components and goods.
• Raise and pull outward the front part of the panel by hands, take off the panel and then the stacker can be used as pallet truck cart or
pallet stacker.
• The brakes on back wheels are installed for the purpose of safety in operation process. When the forks are rising for lifting goods or is
used as an operation platform, the brakes should be stepped down with foot to prevent the stacker from moving.
6 Troubleshooting

Troubleshooting
The lifting height can not meet
the design requirement.
Insufficient operation oil.
To fill oil into the oil cylinder, turn out the
bolt, fill in filtered and clean operation oil
to the oil inlet height and then tighten the
bolt.
When the hand lever is pulled,
the forks do not rise.
The viscosity of the operation oil is too great or no
operation oil has been filled in.
Replace or fill in operation oil according
to the oil quantity regulated.
There is foreign matter in operation oil, which makes
the oil inlet valve cannot be tightly closed.
Filter out the foreign matter or replace
operation oil according to the stipulation.
The oil draining valve, unloading hand lever and
tension spring do not work and not at the lowest
position or blocked by other foreign mater.
Examine the tension spring to see if it is
correct, adjust the unloading hand lever
to the lowest close position and remove
foreign mater.
The positions of the oil draining valve and unloading
hand lever have not been correctly adjusted.
Readjust the unloading tension bar nut
position.
After being raised, the forks do
not decline.
The unloading hand lever is not correctly adjusted
Adjust as described above.
Over heavy load deviation so the piston permanent
deformation occurs.
Disassemble for maintenance or replace
the piston rod
The fork frame, roller or chain wheel is blocked.
Disassemble for maintenance or replace
bearing
Oil leakage.
Damaged or failed seal washer.
Replace with new sealing washer.
There is slight crack or through hole in individual
component.
Repair or replace new components
Loose thread connection or non-tightly pressed
sealing ring.
Repair and tighten.
