293225 Power Parallel Double Scissor Lift Table
POWER PARALLEL DOUBLE SCISSOR LIFT TABLE
Model No: 293225, 293226
The Power Parallel Double Scissor Lift Table is a movable lifter
designed to lift or lower a rated load. It is important to operate
the lift table properly to prevent serious injury.
Product Information
In accordance with EN1570, Safety Requirements for Lifting
Tables, the basic requirements for the lift table are as
follows:
- 100% of the rated load (maximum load) uniformly distributed
over the entire platform area. - Or 50% of the rated load (maximum load) uniformly distributed
over half the length of the platform. - Or 33% of the rated load (maximum load) uniformly distributed
over half the width of the platform.
The lift table must be installed securely either on the
floor/ground or in a pit. Double or triple vertical scissors tables
should be fixed to the floor/ground using expander bolts or similar
methods. All other lift table types, except mobile units, should
also be securely affixed to prevent unintentional movement.
The base frame of the lift table is not self-supporting and
requires a flat and stable flooring. If necessary, the installation
area or pit should be well drained. The mechanical/electrical
installation should be done in accordance with the manufacturer’s
instructions.
Product Usage Instructions
- Utilize a lifting sling through the scissor package. Tie the
base frame to the platform or the scissor mechanism. - Position the lift table in the desired location, ensuring that
the fixed arm end is on the side where the load will be moved on or
off at the upper level. - Check the operation of the safety frame on all sides.
- Position the control device in a way that allows the operator
to have a clear view over the lift table and the load at all times
during operation.
Before operating the lift table, perform a daily inspection to
identify any malfunctions or faults. Do not use the lift table if
any issues are found. Check for scratches, bending, or cracks on
the lift table. Ensure smooth movement of the table and check for
hydraulic oil leakage. Verify the vertical creep of the table and
ensure all bolts and nuts are firmly tightened.
When operating the lift table, follow these guidelines:
- Ensure that the load does not exceed the rated load.
- Distribute the load evenly on the lift table.
- Follow proper safety precautions and warning instructions.
It is important to note that any modifications to the lift table
should only be done with the manufacturer’s written permission.
Additionally, only use spare parts designated by the
manufacturer.
USER MANUAL
POWER PARALLEL DOUBLE SCISSOR LIFT TABLE
MODEL NO. 293225, 293226
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.

NoteMaximum load refers to the load being uniformly distributed over the entire platform area.
In accordance with EN1570, Safety Requirements for Lifting Tablesthe basic requirements are:
100% of the rated load(maximum load) uniformly distributed over the entire platform area.
or 50% of the rated load(maximum load) uniformly distributed over half the length of the platform.
or 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 typeswith the exception of mobile unitsare securely affixed on the floor to Prevent 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
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.

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.
3
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. 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 not more than rated load. Load should be distributed on the lift table equably. LIFTING THE TABLE
4
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.
