DO NOT use this stacker at all if repairs are required or if you suspect a malfunction.

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 whenreleased ?

(1) Lifting and Lowering
Forks can be lifted and lowered by operating Lifting & Lowering Lever.
① Forks lift up by tilting the lever towards operator② Forks lower by pushing the lever forward.
Lifting and lowering speed can be adjusted by pushing and tilting angle.

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 theload within loading diagram(※) capacity.
※ Load Center is the distance from root of thefork for the max capacity available. Refer tothe loading diagram of each model.

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 loweringand sudden stop may result in impact load and damage the unit.

(2) Moving (Maneuvering)
Hold Handle and move unit carefully.

DO NOT move or turn around with load kept at high position.
DO NOT push Lowering Lever when moving.

(3) Brake
Brake is installed on the right side flexible wheel.
① To Lock Step down the lever of the caster to lock thebrake on the wheel.
② To Release Pull up the brake lever by toe.

Make sure to set the brake whenever the lift is not moving.

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 dangerof explosion.
・Charging the battery with insufficient battery fluid
repeatedly also could result in the risk of explosion.

Charging port

The charging port
must be connectedusing a socketwith a sealattached.

■ Battery Life
① Battery is a consumable product and is not applicablefor the product warranty.
② Battery can be used for 150 to 180 charges, butmaintenance and storage conditions also strongly
influence the life of battery.

Do not connect sockets
without a seal attached.
Connection at this port
will not charge thebattery.

Cover the battery termial completely. Electrical short circuit can cause danger of fire, orelectric shock. DO NOT overcharge or boost the charger. Also DO NOT discharge the battery
100%.

Perform the periodic inspections for safe operation.
1. Ensue that tha chain is not rusted, broken, cracked, or missing links (Monthly)
2. Ensure that battery terminal cover is without abnormality (Monthly)
3. Check the sliding portion of roller inside post, grease fitting of the chain
bracket portion, and grease up the chain. (Every 6 months)
4. Ensure that the density of each battery cell is 1,270 (at 20°) or greater
after charging. (Every 6 months)
5. Change the motor oil (Every 12 months)■ Types of Hydraulic Oil■ Replacing Battery
