USER MANUAL
POWER SCISSOR LIFT TABLE
Model no. 293223, 293224
Owner/Operator must read and understand this manual

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 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:
Ⅰ100% of the rated load(maximum load) uniformly distributed over
the entire platform area.
Ⅱor 50% of the rated load(maximum load) uniformly distributed
over half the length of the platform.
Ⅲor 33% of the rated load(maximum 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 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

4
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 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.
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. Loading/unloading at

3. 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.
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 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.

6
◇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.
5. OPERATING THE LIFT TABLE
■LOADING
The maximum capacity of the lift table is 1000kg. 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.

7
■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.
