Warning

Follow the instruction otherwise death or serious injury may occur.

DO NOT lift people.
People could fall and could create severe injury.

DO NOT enter under the table.
In case you have to, unload the lifter and lockthe safety bar.

DO NOT put a foot or a hand in scissors
mechanism.

DO NOT put a foot under the table.

DO NOT overload the lifter.

It may lead load fall or damage on the lifter.
When transferring load to the table, occasionallyunbalanced load might lead the lifter fall.
In used for transfer purpose, ask the
manufacturer for information in advance.

ー1ーCaution
1. Read this operation manual carefully and understand completely before
operating the lifter. Improper operation leads to an accident.
2. This lifter is designed to lift up and down the load under the rated
capacity, using more than 80% of the table surface. Do not use the lifterfor other purpose than its intended use.
3. The tact time of this lifter should be more than three minutes. Do not use
it at high frequency or high speed.
4. Do not allow person to operate the lifter, who does not understand its
operation.
5. Keep watching the load condition. Stop operation of the lifter if the load
becomes unstable.
6. Practice maintenance work according to the service manual.
7. Do not modify the lifter without the manufacture s written consent.
8. Put the load well-balanced on more than 80% of the table surface while
lifting the load. Unbalanced load leads to machine damage or poor
durability.
9. Be aware of unbalanced load while transferring the load.
10. Remove load from the table and lock the safety bar at the time ofmaintenance and inspection.
11. Stop operating immediately when the table reaches to the highest or
lowest possible position. The motor or the coil would overheat and burnout.
12. Do not put unbalanced load on the table as shown below.

X104103 Installation of lifter
Warning
Follow the instruction otherwise death or serious injury may occur.

Do not install the lifter on inclined surface.
It leads to damage or fall of the lifter.

Do not hold the table when moving the lifter.
One side of the table may be lifted and it leads to adanger.
Hold the base when moving the lifter.

Caution
1. Installation should be done where there is no space between the base andthe floor. In case of any space, the base may bend.
2. The power cable should be shorter than 10M and its cross section should belarger than 2 square millimeter. Long or thin cable may cause overheat of themotor or the cable, which leads to a danger.
3. Install the lifter where the ambient temperature is between 0℃ to 30℃.
4. This lifter is not designed to be water-proof or for outdoor use. Install thelifter indoor under dry circumstances.
ー3ー1. Check if the installation floor is flat.

Caution※ Install the lifter where the ambient temperature is between 0℃ to 30℃.
※ This lifter is not designed to be water-proof or for outdoor use. Install thelifter indoor under dry circumstances.

2. Unpack the lifter and place it at the desired place. In case of any space
between the base and the floor, fill it with some spacer or cement.

Caution※ Do not hold the table while moving the lifter. One side of the table may belifted, which leads to a danger.

3. Connect the power cable to the power source and check the movementof the lifting unit.

Caution※ If the table does not rise while the motor is working, this could be due to theopposite rotation or single phase movement of the motor. In that case,exchange two of three cables or make sure if all three cables are connected
and turned on.
※ The power cable should be shorter than 10M and its cross section should
be larger than 2 square millimeter. Long or thin cable may cause overheatof the motor or the cable, which leads to a danger.

4. If necessary, fix the lifter with anchor bolts.

4 Daily inspection before working
Daily inspection is important for safety and early discovery of malfunction. Checkthe followings before working.
(1) Check if there is any abnormality on the appearance.
(2) Check if there is any foreign article inside of the lifting unit.
(3) Check if the quantity of oil is sufficient.
(4) Check oil leakage from the piping, cylinder or hydraulic unit.
(5) Check if there is any abnormality on the electric circuit. Check if the lifting
movement is smooth.
(6) Check unusual wear on the lifting unit.
(7) Check unusual noise from the lifting unit, motor or pump.
(8) Check the looseness of the screws and bolts.

CautionRemove the load from the table and lock the safety bar while working under
the table for maintenance or inspection.
ー4ー5 Operation of lifterThis lifter is operated by push buttons or foot switch.
Push UP button (pedal) and the table goes up.
Push DOWN button (pedal) and the table goes down.

CautionStop operating immediately when the table reaches to the highest or lowest
possible position. The motor or the coil would overheat and burn out.

Safety bar
This lifter is equipped with a safety
bar in case of working under thetable for maintenance or inspection.
Lock the safety bar without failwhile working under the table formaintenance or other works.

How to lock a safety bar(1) Remove all loads from the table.
(2) Raise the table at the highest position.
(3) Rotate the safety bar and put it on the base.
(4) When lowering the table, the safety bar
touches the base end, which stops the table(5) That is how to lock the safety bar. Practice
maintenance.
(6) After maintenance, raise the table and put thesafety bar back to the link.

6 Periodical inspection
Warning
Remove the load from the table and lock the safety bar while working under
the table for maintenance or inspection.
Periodical inspection is important for safety and early discovery of malfunction.
Inspect periodically the below said parts. There are some difficult parts to beinspected correctly by a customer and inspection by the dealer is recommended.

7 Adjustment of lowering speedWarning※ The lowering speed is preset under the specified load before delivery.
Adjust the speed as less as possible because too much increase oflowering speed may leads to a danger.
※ When speed is adjusted with no load, there might be a case that lowering
speed gets too fast with load, which leads to a danger.
