1. 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 underf 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 (maximu m load) uniformly distributed over the entire
platform area.
II or 50% of the rated load (maxi mum load) uniformly distributed over half the
length of the platform.
III or 33% of the rated load (maxi mum load) uniformly distributed over half the
width of the platform.
2. 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 silimar, We also
remommend that all other lift table types, with the exception of mobile units, are securely
affixed on the floor to Pr event unintentional movement
Mechanical/electrical installation
1. 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.
2. Utilize a lifting sling through the scissor package. Tie the base frame to the
platform or the scissor mechanism. Locate the table into the desire position. Turn
the fixed arm end to the side where the load will be moved on or off at upper level.
See picture below.
3. Check the operation of the safety frame on all sides.
4. 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.

3. CAUTION! If operationg the lift table improperly. A
person may be injured. Therefore, operate
properly according to the follwing instruction.
◇ The lift table is a moveable 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 manufacture’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 safety.
◇ Keep the hydraulic system under clean and safe condition.
◇ The hydraulic power pack features an electric lowering control those coils. The
coils must be fed with the power supply voltage should not exceed + 10% of the
rated required votage.
◇ 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.
4. 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 n o t u se th e l i ft ta b le if an y
m al f unct ion o r f a u l t i s f o u nd .
◇ 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 dydraulic oil leakage.
◇ Check the vertical creep of the table.
◇ Check if all the bolts and nuts are firmly tightened.
5. Operating the lift table
■ LOADING
The maximum capacity of the lift table is 1000kg/2000kg. Load should be
distributed on the lift table equably.
■ Lifting the Table
CAUTION! Do not ov erl oa d the l ift ta bl e.
En su re th e ba l an c e of l oad ing . Do n o t l o ad
pa rti all y o r c o n c en tri ca ll y
◇ 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 righbolts.
◇ Pay attention to the maximum capacity of lifting equipment to be used.
◇ Keep the righbolts with reasonableness.

⑤ Upper arm fixing
⑥ Upper running wheel

When greasing the bearing the lift table must not be loaded! When determining oil
levels, bear in mind that the tank contains the greatest amount when the lift table
is in its lowest position. Hydraulic oil must be treated as dangerous waste!
