Perform the Pre-Operation checks before operating everyday.
1. Any damage, distortion or crack in post
2. Any damage, distortion or crack in carriage and forks
3. Smooth movement of front and rear wheels
4. Any oil leak from hydraulic line or cylinder
5. Any damage, kink or crack in chain
6. Check if brake works properly
7. Any natural lowering
8. Fastening of bolts and nuts
9. Is battery liquid at adequate level ?
10. Looseness of battery terminal
11. Is battery fixed firm ?
12. Smooth movement of Lifting & Lowering Lever. Does lever return to neutral when released ?
13. Check smooth operation of handle. Any excessive over-steering ?
14. Check smooth operation of Accelarator Switch. Does switch return to neutral when released ?
Check the smooth operation for driving forward, reverse, high speed and low speed.
15. Check the operation of Main Switch and Emergency Stop Switch.
16. Check the noise, excessive wear and uneven wear of the Drive Wheel.
17. Check if the battery is charged.
(1) Preparation of the operation
① Insert the Key into Key Switch and turn clockwise.
② Turn on Main Switch.
(2) Lifting and Lowering
Forks can be lifted and lowered by operating
Lifting & Lowering Lever.
① Forks lift up by tilting the lever towards operator
② Forks lower by pushing the lever forward.
Lifting and lowering speed can be adjusted by pushing and tilting angle.
※ Load Center is the distance from root of the fork for the max capacity available.
Refer to the loading diagram of each model.
(3) Driving Operation
① Drive the lifter by operating Accelarator
Switch.
② Driving speed in both forward or reverse
driving can be adjusted by the operation of
Accelarator Switch.
③ Pushing Switch further would increase speed.
④ Lifter stop immediately when pushing the
"Emergency Stop Switch".

DO NOT use this stacker at all if repairs are required or if you suspect a malfunction.
DO NOT lift up the load or anything above the rated capacity.
DO NOT lift the load only at the tip of the forks. Lift up the load within loading diagram(※) capacity.
DO NOT keep lifting with excessive slow lifting speed and continuously over 40 seconds.
Rapid lowering operation may result in load collapse and dangerous. Also rapid
lowering and sudden stop may result in impact load and damage to the unit.
Main Switch would be turnd "OFF" in case of overload
operation to protect motor.
DO NOT move or turn around with load kept at high position.
DO NOT jump start and turn steep which may result in uncontrolable and unstable of lifter.

(4) Horn
Push the horn button.
(5) Volt Meter
Volt Meter shows the voltage of battery. Refer to for the battery remaining capacity.
(6) Battery and Charging
■ How to Charge Battery
① Make sure that battery fluid is present upto the designated fluid level.
Add purified water if the fluid is insufficient.
② Unplug the battery socket and insert the charging device into the open
socket (indicating as "charging port") to charge the battery.
③ Refer to the instruction manual supplied with the charger regarding
methods of use.

・Keep battery away from open flame when charging.
Battery may be at risk of explosion.
・Choose a well-ventilated area to charge the battery.
Hydrogen gas may be produced, creating the danger
of explosion.
・Charging the battery with insufficient battery fluid
repeatedly also could result in the risk of explosion.
Cover the battery termial completely. Electrical short circuit can cause danger of fire, or
electric shock. DO NOT overcharge or boost the charger. Also DO NOT discharge the battery
Charging port
The charging port
must be connected
