Note: Owner/Operator must read and understand this instruction Manual
before using the low profile lift table
THANK YOU VERY MUCH FOR SELECTING OUR PRODUCT. THIS INSTRUCTION MANUAL
DESCRIBES CORRECT OPERATING METHOD TO ENSURE PROLONGED SERVICE LIFE. PLEASE
READ AND COMPLETELY UNDERSTAND THIS MANUAL BEFORE OPERATING THE LOW PROFILE
LIFT TABLE. ALWAYS KEEP THIS MANUAL AT AN APPROPRIATE PLACE. IF THE MANUAL OR
WARNING DECAL IS MISSING, PLEASE CONTACT WITH DEALER.
Note: This Manual has been prepared for skilled and competent personal.
It provides instructions for using the product correctly and parts list. This
Manual cannot replace the professional skills and expertise of the user.
WARNING! If operating the lift table improperly, a person may be
seriously injured. Therefore, operate properly according to the following
instruction
- Read & thoroughly understand the Instruction Manual completely before using. Follow all safety instructions strictly.
- It is necessary to check all safety devices before operation.
- Make sure that there are no obstacles in the working area.
- Do not put foot or hand in scissors mechanism or through frame.
- Screw the lifting eyes on the base frame before working on the lift table.
- Do not overload the lift table. Load should be distributed on the table according to relevant load distribution chart.
- Pay attention if local voltage and frequency is as same as the input specification of the lift table.
- Use the lift table on flat and solid ground.
- All the electrical connection and disconnection operations must be carried out by skilled and competent personal.
- While operation, it is forbidden to contact the moving parts of the lift table.
- While the lift table moving, it is forbidden to adjust or to move the load.
- It is forbidden to lift the load, which perhaps does harm to a person or other object.
- It is forbidden to operate the lift table while a person is under the table.
- Do not adjust the safety valve of hydraulic power pack.
- It is forbidden to operate the lift table even if there is small structure distortion.
- Do not use in an explosive or flammable place.
Note！Maximum load refers to the load being uniformly distributed over
the entire platform area.
In accordance with EN1570,Safety Requirements for Lifting
Tables the basic requirements are:
Ⅰ 100% of the rated load(maximum load) uniformly distributed over the entire
platform area.
Ⅱ or 50% of the rated load(maximum load) uniformly distributed over half the
length of the platform.
Ⅲ or 33% of the rated load(maximum load) uniformly distributed over half the
width of the platform. 
INSTALLATION OF LIFT TABLE ON THE FLOOR/GROUND OR IN A PIT
Double or triple vertical scissors tables must be fixed to the floor/ground by means of expander bolts or similar We also recommend that all other lift table types with the exception of mobile units are securely affixed on the floor to Prevent unintentional movement
Mechanical/electrical installation
- The base frame of the lift table is not as standard self -supporting .It is important that the flooring is flat and stable and that the installation area or pit, when necessary, is well drained.
- Utilize a lifting sling through the scissor package. Tie the base frame to the platform or the scissor mechanism. Locate the table into the desired position. Turn the fixed arm end to the side where the load will be moved on or off at upper level. See picture below.
- Check the operation of the safety frame on all sides.
- The control device should be positioned so that the operator has a clear view over the lift table and the load at all times when the lift is operated.

CAUTION! If operating the lift table improperly, a person may be injured. Therefore, operate properly according to the following instruction.
-
The lift table is a movable lifter designed to lift or lower rated load. Do not use it for other purpose.
-
Do not allow a person to operate the lift table, who does not understand its operation.
-
It is forbidden to change the lift table without manufacturer’s written admission.
-
It is necessary to use the spare parts designated by manufacturer.
-
Make sure to keep a distance between the table and ambient objects enough to operate the lift table safely.
-
Keep the hydraulic system under clean and safe condition.
-
The hydraulic power pack features an electric lowering control.
The coils must be fed with the required voltage as described on those coils. The power supply voltage should not exceed ±10% of the rated required voltage. -
Always do maintenance and routine check while the lift table is unloaded.
-
The lift table is not waterproof and should be used in a dry environment.
DAILY INSPECTION
Daily inspection is effective to find the malfunction or fault on the lift
table. Before operation, check the lift table according to the following
points.
CAUTION! Do not use the lift table if any malfunction or fault is found.
- Check all the terms of WARNING and CAUTION.
- Check scratches, bending or crack on the lift table.
- Check smooth movement of the table.
- Check if there is any hydraulic oil leakage.
- Check the vertical creep of the table.
- Check if all the bolts and nuts are firmly tightened.
OPERATING THE LIFT TABLE
■ LOADING
Load should be distributed on the lift table equably.
■ Lifting the Table
CAUTION! Do not overload the lift table. Ensure the balance of loading.
Do not load partially or concentrically.
-
Screw and loose emergency stop switch.
-
Push the UP button and power pack starts to work to lift the load.
-
Loose the UP button and power pack stops working.
■ LOWERING THE TABLE
WARNING! Do not put foot or hand in scissors mechanism. -
Push the DOWN button and the table will lower.
-
Loose the DOWN button and the table will stop.
NOTE -
The table is equipped with an aluminum guard to avoid accidental danger.
-
If aluminum guard strikes an object while the table lowers, stop operation and check the lift table. After making sure no any abnormality, strike the UP button slightly and then the electric system will function as before.
EMERGENCY STOP
There are two methods of emergency stop as follows.
◇ Push down the emergency stop switch and the movement of table stops.
◇ Strike aluminum guard upward and the movement of table also stops.
■ TRANSPORTATION
If necessary, the lift table can be transported with attached ringbolts.
◇ Pay attention to the maximum capacity of lifting equipment to be used.
◇ Keep the ringbolts with reasonableness.
■ MOTOR WORKING TIME
◇ Motor hours of work in one hour less than nine minutes.
