SAFETY
Note: This manual has been prepared for skilled and
competent personal. It provises instructions for using
the product correctly and parts list. This Manual cannot
replace the professional skills and expertise ofthe user:
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.
▲ 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 lif 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.
▲ 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 manu-
facture'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 lower-
ing 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.
Note! Maximum load refers to the load being
uniformly distributed over the entire platform
area.
WARNING!
If operating the lift table improperly, a
person may be seriously! injured. Therefore,
operate properly according to the following
instruction.
CAUTION!
If operationg the lift table improperly. A
person may be iniured.Therefore,operate
properly according to the follwing instruction.

DAILYINSPECTION
OPERATING THE LIFT TABLE
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.
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.
▲ 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
The maximum capacity of the lift table is
2200lb/4400lb/8800lb. Load should be distributed on
the lift table equably.
▲ 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,
▲ Push the DOWN button and the table will lower.
▲ Loose the DOWN button and the table will stop.
▲ 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.

CAUTION!
Do not use the lift table if any malfunction or

WARNING!
Do not put foot or hand in scissors mechanism.
CAUTION!
Do not over load the lift table.Ensure the
banlance of loading. Do not load partially or
concentrically.
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 Prevent

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.
Emergency stop
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.

▲ Do routine check of fasteners, packing and oil
leaking.
▲ Do routine check of the function of the lift table.
▲ Before service the lift table, make sure to turn off
the AC power supply.
▲ After service it is necessary to check the function of
the lift table again.
▲ ONLY a qualified personel can do service work.
▲ Do routine check of the micro-switches on the
safety guard.
▲ Do routine check of the hydraulic system by listening
its noise, touch motor's surface.
▲ Caution: It is necessary to turn off the AC power
supply before touch motor's surface
▲ Pay attention to clear or even replace the oil filter
after operating for a long time.
▲ Appropriate lubrication is necessary to make the lift
table work easily and have a prolonged service lift.
▲ Following table is recommended to service the lift
table periodically.
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!
