5．Use and operation instruction
The electric pallet stacker adopts storage batteries as the dynamic source for short distance goods handling
and stacking. Correct use and operation will bring great convenience to your work but incorrect use and
operation will damage the stacker or pose risk to you and your goods.
5．1Before operation：
Warning
It is strictly forbidden to use faulty truck.
5．1．1 Before operation, please check if the truck is in normal condition: Is there any oil leakage in the
hydraulic pipes? Are the supporting wheels able to operate normally? Is there any block? The trucks
with problems are prohibited for operation.
5．1．2 Check if there is any electric power in the batteries with the method indicated in Fig.I. Pull the general
power switch out to turn on the general power supply, unlock the electric lock on the handle, check

10
the electric energy meter on the instrument panel of the truck. If the zero end grid is bright, it
indicates there is no electric power in the batteries and charging should be conducted at once. It is
prohibited to operate the truck without electric power as that will greatly reduce the service life of the
batteries and even damage the batteries.
5．1．3 Check if the truck brake is normal. Check the lifting, dropping, forward and backward traveling of the
truck to see if the actions are normal. Check if the emergency reverse action of the truck is normal with the
method indicated in Fig.II:
Warning
It is strictly forbidden to turn the accelerator knob fastly to speed up
the stacker abruptly during goods transportation.
Move the control handle to division A or division C as indicated in Fig.II and press the rise/lowering button on
th control handle to see if the lifting and lowering of the fork is normal. Then turn the control handle to
division B as indicated in Fig. II, slowly start the truck and press the handle to the horizontal position to
check that whether the truck can travel and brake normally.
Move the control handle to division B as indicated in Fig.II, press the emergency reverse button on top of the
control handle to ckeck that whether the truck can travel backward normally.

5．2 In operation：
5．2．1
Accelerator knob: The accelerator knob is used for controlling traveling direction and speed of the stacker.
When it is for the traveling operation, turn the operation handle to B area indicated in the above diagram.
When the handle is in A or C area, the stacker is in a power-off status, and can not travel. When the
operation handle is in B area and the accelerator knob is turned in one direction, the stacker wil travel in that
direction. While the accelerator is turned in another direction, the stacker will travel in another direction.
Meanwhile the bigger the turning amplitude is, the faster the truck will travel.
Note: A side-magnetic brake is installed on the shaft end of the driving wheel motor and there is a cam and
an inching switch installed on the rotary shaft of the rotary arm. Only when the rotary arm is at 45°±35°(as
indicated in Fig. II), the stacker can be turned on and travel. Larger or less than the angle, the stacker will be
powered-off and braked. In that case, the stacker can lift goods. When lifting goods, the stacker cannot
travel. As indicated in Fig. II, when the operation handle is in division A or division C, the stacker can only lift or
lower but not travel; when the control handle is in division B, the stacker can travel as well as lift or lower. The
operation position of the handle will not be specially described in the following descriptions, i.e. the stacker can
only lift or lower but not travel when the handle is in division A or C and the handle must be in division B when
the stacker is traveling.
5．2．2 As indicated in Fig. II, there is a button on the operation handle which is used for slowing down the
stacker. When this “slow down” button is pressed as well as accelerate knob is turned, the stacker will travel at
a low speed. This state is best suitable for turning a corner, stacking and moving into and out of the shelf while
taking goods. When the “slow down” button is released and the accelerate knob is turned, the stacker will travel
at a normal speed.
5．2．3 Safety height：
The safety lift height for mast is about 1.8m (according to the assembled mast): If the mast is lifted to a
height which is over the safety height, the stacker will slow down to about 3km/h.
5．2．4 Operation of handling and stacking:
Notice
Please check the following items before operation of the stacker:
Ensure no goods falling and goods damaged at loading and unloading area.
Ensure no goods or objects impeding for safety.
As indicated in Fig. II, pull out the general power supply switch, unlock the electric door lock, and drive the
stacker to the goods pile nearby. (The tip of the fork is 300mm from the goods pile). Press the lowering button,
adjust the height of the fork to a proper position, and insert the fork slowly and as deep as possible into the
pallet of the goods. Press the lifting button till the fork is 200-300mm from the ground. Drive the stacker to the
location of the goods shelf and stop slowly. (The tip of the fork is 300mm from the goods shelf.) Press the lifting
button and the fork rises to a proper height with the shelf (The bottom of the pallet is about 100mm higher than
the goods shelf). Move the goods slowly to the accurate position of the shelf and press the lowering button to

12
put the goods carefully on the shelf. Take the fork away from the goods and drive the stacker slowly to make the
fork out of the goods pallet. (The tip of the fork is 300mm from the goods shelf.) Lower the fork until it is
300mm from the ground and drive the stacker away from the shelf. Attention should be paid to that there
should be no obstacles around and when turning, the speed should be reduced.
Caution
The driving mechanism of truck is installed on the foreside. Due to this
difference from common vehicles, the foreside of truck swings comparatively fast
when turning around. For this reason, to prevent collision with other objects nearby
the foreside of truck, do drive or turn slowly.
5．2．5 Operation of taking goods off the goods shelves：
As indicated in Fig. II, pull out the general power supply switch, unlock the electric door lock, and drive the
stacker to the goods shelf nearby. (The tip of the fork is 300mm from the goods shelf). Press the lowering button,
adjust the height of the fork to a proper position, and insert the fork slowly and as deep as possible into the pallet
of the goods. Press the lifting button to lift the goods till the bottom of the pallet is 100mm from the goods shelf.
Slowly drive the stacker and slowly move the goods out of the shelf (the tip of the fork is 300mm from the goods
shelf). Press the lowering button and the fork lowers to a height of 200-300mm from the ground. Drive the
stacker away from the goods shelf until it reaches a desired position and then slowly stop it. Press the lowering
button to put down the goods, make the fork completely away from the goods and move the fork slowly out of
the goods pallet.
5．3 Abnormal situation handling during operation：
5．3．1When pressing the lifting button, the fork can rise but when releasing the lifting button, the fork is still
rising. The stacker is in a situation of out of lifting control. In that case, turn off the general power supply switch
to cut off the power supply at once. Drive the stacker to a safe position to lower the fork manually and repair the
circuit of the stacker.
5．3．2 If the brake is out of function when the stacker is in operation, the operation must be stopped at once and
repair the stacker.
5．3．3 When the stacker is moving forward and pushing the operator against a wall or other objects, press
the emergency reverse button on top of the operation handle and the stacker will automatically move backward

Charging operation methods: This stacker is equipped with a fixed charger. And other built-in chargers are
also optional. When the fixed charger is used for charging, first open the side door to pull out the socket
connector to insert it into the socket joint of the fixed charger. Then insert the plug of fixed charger into two
phase AC power. Finally the charger will start charging after several seconds. When the built-in charger is used
for charging, first open the cover of battery case to take the charging plug out of the battery case, then insert
the charging plug into the two phase AC power. And the charging will start after several seconds.

6．1 Initial charge
6．1．1 Initial charge should be conducted for batteries that have never been used
6．2 Use and maintenance
6．2．1 In order to guarantee the service life of the batteries, the batteries in use should be fully charged.
Insufficiently charged batteries must not be used. During the process of use, close attention should be paid to
the discharge extent. Over discharge is prohibited.
6．2．2The batteries in normal use should avoid over-charge, but over-charge must be properly conducted for
the batteries in following situations, i.e. equalizing charge.
a. The “lag-behind” batteries--- batteries with a voltage lower than that of the other batteries in the
discharging process and the batteries having been repaired for failure. (When equalizing charge is
conducted, the positive and negative poles of the “lag-behind” battery should be respectively
connected with the positive and negative ends of the charger, the DC power supply, and the charge
should be conducted independently.)
b. Equalizing charge should be conducted for the batteries in normal use every 2-3 months.
c. Equalizing charge should be conducted for the batteries that have not been used for a long period of
time before use.
6．3 Storage
Batteries should be stored in a clean, dry and well ventilated warehouse with a temperature of 5-40℃. The
valid shelf life is 2 years. The batteries should be kept according to the following requirements during storage:
a. No direct sunshine on the batteries and at least 2m away from heat source.
b. Avoid contacting with any harmful substances. No metallic matters are allowed to drop into the
batteries.
c. The batteries should not be placed upright down and should not be impacted mechanically or
heavily compressed.
The batteries must not be stored with electrolytic solution. When it is required in special situation that the
batteries must be stored with electrolytic solution, the batteries should be fully charged and the density
and the liquid surface of the electrolytic solution should be adjusted to the stipulated values. When the
storage period comes to one month, the batteries should be complementarily charged with the
common charge method.
6．4 Charger
If the charger you use is full automatic type. It must meet with the following 2 requirements:
a. The output voltage of charger: 24V
b. The output current of charger: 30A
Warning
There is hydrogen gas accumulated in the battery case during
charging. Thus the charging environment requires good ventilation and
there should be no flame, otherwise explosion or fire may occur.

9．Periodic maintenance and repair:
Comprehensive check for truck can avoid malfunction and ensure the service life. The hours listed in
maintenance procedures is based on the cases that the truck works for 8 hours per day and 200 hours per
month. For the sake of safety, maintenance shall be carried out according to maintenance procedure.
Notice
All the repair work shall be carried out by professional personnel.
Please contact the sales department of our company if you need to adjust or replace the components.
9．1 Precautions during maintenance：
Notice
The components for replacement shall be produced completely by our
company. When replacing components of the truck, the components with the
same safety requirement with the original design shall be used.
The lubricating oil and hydraulic oil in use shall be recommended by our
company.
⑴Places for maintenance:
Notice
The places for maintenance shall be appointed and can provide other services
such as hoisting and safety protection facility etc.
The places shall have level ground and good ventilation.
The places shall be equipped with fire-extinguishing devices.
⑵Before service maintenance matters needing attention:
Notice
No smoking.
Arrange the self-protection work.
Wipeout the effusive oil in time.
Before adding lubricating oil, clean up the dirty oil or dust on the joint with brush or
cloth.
Except certain situation, turn off the key switch and pull off the power socket.
Lower down the fork arms to the lowest point when carrying out maintenance.
Ensure no goods on the truck when demounting the high pressure oil pipe. Besides,
the fork arms shall be descended to the lowest position, by this way, the pressure of
hydraulic system can be released.
For the reason that there are capacitors storing a little amount of electric energy in
circuit, so before contacting the binding post of the main circuit, discharge at first.
Clean the electric section with compressed air, never flush with water.
When the truck requires high-position maintenance, the altitude safety
protection must be carried out for the repairing and maintenance personnel.
