3. Operating features of the machine
3.1 The machine has the same working function as the normal stacker.
3.2 When stacking, we can make the left or right side of the machine
1

nearer to the stacking area, then turn the winch to tilt the fork,
overturn the material to the stacking area or on the stacking goods,
without unloading by man, which is safe and free of labor.
3.3 Because the capacity of load is not big, the height of stacking is not
high, the operating force of winch is not big when tilting.
4 Safety rules
4.1 Optimum safety
4.1.1 Use the correct operation, the operator should stand after the
control level whenever push/pull or ascend/lower.
4.1.2 When using the lateral tilting function, the operator should stand
the reverse side of the stacking area to operate the winch. Pay
attention to the direction of operating the winch, which can not
be wrong, or so may result in death or damage of material.
4.1.3 Avoid overloads
Note: the center distance of load and load is inverse ratio, that is
the load center is nearer to the heel of the fork, the load is bigger,
while the center distance is farther, the load is smaller. (Dia.1)
Please obey this regulation strictly, never exceed the regulation of
this diagram, because the weight and center of the load influence
the intensity of the fork, if it is overloaded there is a risk of
bending. Diagram
Dia.1 2

4.1.4 Avoid offset loads
Except obeying the regulation of diagram, the load must be
distributed evenly on forks or pallets, avoid of left or right offset,
then the load will not overturn when lifting or transporting.
4.1.5 Driving loaded
The machine is designed for use on even and level floor. During
transport the forks shall be raised as little as possible. Transport
with raised forks should be made over the shortest possible
distances and at low speed. Do not transport when tilting goods
on the machine, this is not safe.
4.1.6 Driving the machine on the slope
1) The machine shall be unloaded or a small load.
2) The load shall be in the lowest position.
3) The gradient shall be no more than 2°when dragging the
machine.
4) The operator shall be on the upper position whether upgrade or
downgrade.
4.2 Safety regulations
1) Never stand or walk under a raised load.
2) Before lowering the forks, make certain that no foreign elements
can hinder the free lowering of the forks.
3) The machine is designed for use on even and level floor.
4) During transport the forks shall be raised as little as possible.
5) Transport with raised forks should be made over the shortest
possible distances and at low speed.
6) Brake when lifting or lateral tilting load in stacking area.
7) Do not use a damaged or malfunctioning machine.
8) Do not use a machine with a worn, damaged or more than 3%
elongation chain.
9) Conduct a thorough pre-operation inspection prior to each use.
5 Maintenance and operating instructions
3

5.1 Lifetime of the machine
Regular inspection, repair and the replacement of worn or defective
parts in good time will prolong the life of the machine.
“Prevention is better than repair”, therefore ensure:
5.1.1 Correct usage.
5.1.2 Regular cleaning.
5.1.3 Oil changes at the correct intervals.
5.1.4 Periodic safety inspection.
5.2 Lubrication and oil change
Under normal conditions the machine requires no lubrication (except
bearing of tilting assembly). All ball bearings are sealed or
half-sealed and treated with molybdenum disulphide grease. So it
has self-lubricating function during moving.
Use the hydraulic type oil according to the table below.
Temperature
Oil
-20℃~+40℃
L-HV46 Hydraulic oil
5.3 Oil change
5.3.1 Draining:
1) Lower the forks to bottom position.
2) Loosen the screw (1112) of filling hole in external cylinder.
3) Remove the discharge valve shaft (133) and spring (135), then
drain off the oil in external cylinder. If remove the discharge
valve body (130Q) and steel ball (129), drain off the oil in
external cylinder, pump piston and oil pipe normally.
5.3.2 Filling:
1) Install the lowering valve assembly.
2) Fill the hole with oil. Oil quantity: 1.1 liters.
3) Expel the air from the pump unit, then tighten the screw of filling
hole.
5.4 Seal leakage
Locate the point at which oil leakage appears and then replace
defective seals. 4

5.5 The safety valve does not seal completely
The safety valve (W) will open when the load reaches the 20% of the
capacity, the safety valve must seal completely in capacity, no
leakage. (This has been set in factory, do not regulate it under
general conditions.)
With a certain load on the forks, press the pump rod by the control
lever quickly so that oil quickly flows over the hydraulic valve. If the
forks do not lift or tilt, it is because that the overflow valve does not
close (not seal), regulate the pressure of the spring of the overflow
valve. If this does not solve the problem, the valve insert must be
replaced by new ones or the whole safety assembly.
5.6 Bleeding the hydraulic system
The pump will not operate if there is air in the hydraulic system.
The system can be bled as follows:
1) Loosen the screw (1112) of the filling hole in external cylinder.
2) With a certain load on the forks (about 200kg), pump the control
lever to make the forks up to the top, then open the lowering valve
quickly to make the forks down to the bottom.
3) Open the lowering valve, keep on pumping the control lever many
times, then lift fork again, lower again until expel the air.
5.7 Adjustments of the three working positions of the handle
5.7.1 Three working positions of the handle
1) Lift position (the position of fork lifting): The handle is in the bottom
position.
2) Normal position (Neither lift nor lower position): The handle is in
the neutral normal position.
3) Lower position (The position of fork lowering): The handle is in
the upper position.
5.7.2 Adjustment of normal position
1) Place the handle bar in normal position.
2) Press the control lever to the lowest position.
3) Regulate the nut (H1104) on the guiding rod (H5906) of control
5

lever and the regulating screw (140M) on the crank link (139M) to
make the crank link be dragged (now the lowering valve is open,
but hydraulic valve is close), while the forks in the state of neither
lower nor lift position.
5.7.3 Adjustment of lifting position
1) Place the handle bar in lifting position.
2) Pump the control lever, the crank link (139M) shall not be dragged
(now the lowering valve and hydraulic valve is close), the forks in
the working state of lifting.
3) If the forks do not lift, regulate the nut (H1104) and the regulating
screw (140M), until satisfy the needs of normal position and lifting
position simultaneously.
5.7.4 Adjustment of lowering position
1) Pull the handle bar in lowering position.
2) The crank link (139M) shall be dragged, and make the lowering
valve and hydraulic valve open completely, the forks in the
lowering state.
3) If the forks do not lower, regulate the nut (H1104) and the
regulating screw (140M), until satisfy the needs of three state
positions simultaneously.
5.8 Forks height adjustment
Two rollers (F1207) in the upper carriage are mounted on eccentric
axle (F5922), turn the eccentric axle, and adjust the tilting angle of
the carriage so that they can be adjusted.
Adjustments:
1) Loosen the setting screw (F5919, each one on the left and right.).
2) Lock the hexagon point of the eccentric axle (F5922) with a wrench,
the eccentric axle can now be turned to give the necessary
adjustment.
3) Turn the eccentric axle back can make the fork tilt to the front (that
is the front is low and the back is high), Turn the eccentric axle front
can make the fork tilt to the back (that is the front is high and the
6

back is low).
4) To ensure the same load on all rollers, the eccentric axle (F5922)
must be adjusted on both sides and to the same position.
5) Tighten setting screw M8 of each side after adjustment.
Note: The eccentric axle can only adjust the front or back of fork, can’t
adjust the tilting clearance of left or right of fork.
5.9 Cleaning
When cleaning the machine, do not direct the jet onto bearings and
seals. Otherwise the grease will be washed out and the life of the
equipment shortened.
6 Troubles shooting

replacement of worn parts might be necessary. For the frequency of
