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

① Piston rod bearing

② Lower running wheel

③ Lower arm fixing

④ Arm center

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!
