2.2 Main structure principles:
zLifting mechanism: Each column is installed
with a hydraulic cylinder, when hydraulic oil is
pressed from power pack into the lower
chamber of main cylinder, piston rod moves
upwards to drive the upward movement of
carriage through leaf chain.
zLoad supporting mechanism：When vehicle
drives into the working area, adjust the angle
and telescopic length of arms to make lifting
pads at an effective load supporting position
that contact with vehicle, then adjust the lower
screw ’s height of lifting pad to make it
applicable for vehicles with different chassis.
zBalance mechanism：In order to keep machine
balanced during lifting and lowering, two
carriages are interconnected and forced to
move synchronously by two wire ropes. If the
right and left carriages and arms are not at the
same level, adjust the end nut of wire rope and
pull wire ropes tight to make arms leveled.
zManual safety locking system: the safety
locking plates are installed on the two
carriages and the toothed bar plate is welded
on the internal wall of the column. During the
lifting of the carriage, the safety locking plate
goes up against on the toothed bar plate by
the tension of spring. When the carriage stops,
the safety locking plate opens and then is
engaged in the toothed bar slot to ensure the
carriage will not go down; when the lowering
operation is required, just raise the carriage
upward a little to loosen the safety locking
plate from the toothed bar slot, and then
manually pull the steel wire rope so as to jack
up the safety locking plate by sliding plate, so
the safety locking is released so that the
carriage can be lowered down. Because the
manual safety locking systems are installed on
the two carriages, double safety protection can
be provided; therefore, to disengage the safety
locking, the steel rope on the two carriages
shall be respectively pulled. To prevent the
vehicle slip, the swing arm is installed with
positioning mechanism, making the swing arm
capable of automatic locking during operation.
zSafety lock scope: Safety lock mechanism is
effective when the front end of carriage is
between 450mm and 1900mm high above the
ground.

3 Operation Description
3.1 Precautions for vehicle repair
work
zDifferent vehicles have different center of gravity
positions. First understand the position of center
of gravity, and when the vehicle enters into the
lift, make its center of gravity close to the plane
formed by two columns. Adjust the swing arm,
and make the lifting pad support onto the lifting
point of the vehicle.
zFor vehicle lift with top beam ,pay attention to
the car roof position observation in order to
avoid accident during lifting.
zCarefully read the warming symbol.
zThe hydraulic valves have been adjusted before
ex-factory, and the user can’t make
self-adjustment, otherwise it will be responsible
for all the consequences generated.
zBased on the production needs, some
specifications in the instruction manual are
subjected to change without notice.
3.2 Preparation before Operation
zLubricate contact surface of the carriage with
general-purpose lithium grease（GB7324-87）.
All sliding surface should be coated evenly from
the top to bottom.
zFill hydraulic oil N32 or N46 to the oil reservoir of
the power unit.
3.3 Inspection before operation
zCheck to see if the motor power is installed properly.
zCheck to see if all the connection bolt s are fastened.
Note: Don’t operate the lift with damaged
cables or damaged and missing part, until it is
inspected and repaired bythe professionals.
3.4 Lifting the Vehicle
zKeep work area clean, don’t operate the lift in
cluttered work area.
zLower the carriage to the lowest position.
zReduce the swing arm to the minimum length.
zSwing the arm along the route of the vehicle
zMove the vehicle to the location between the two
columns
zSwing the arm and put the lifting pad below the
recommended lifting point, and adjust the height
of lifting pad to touch lifting point of vehicle
zPress the UP button on the electric control box,
slowly lift the vehicle to ensure the load balance,
and then raise the lift to the required height.
zRelease the UP button.
zPress the DOWN button to engage the safety
lock of carriage. At this time, the vehicle can be
repaired.
Note:
Before operation, the safety locking devices
must be Inspected.1) The gear blocks of the
arm end must engage the gear block of the
restraint shaft.2)No broken strand in the steel
cable. 3)No deformation in the arm pad.
When lifting the vehicle, all the swing arms
must be used.
Before lifting the vehicle, check all the
hydraulic hose and fittings for oil leakage. In
case of leakage, please don’t use the lift.
Remove the fitting with leakage and re-seal.
Re-install the fitting and check if oil leakage
still exists.
After the vehicle is lifted, when adding or
removing any major heavy object, use jack
stand to maintain the balance of the vehicle.
3.5 Lowering the Vehicle
zClean the work area before lowering the vehicle.
zFirst press the start button to rise the vehicle a little,
then pull two steel ropes on two carriages to
disengage the safety lock.
zPress the lowering handle to lower the vehicle.
zLower the vehicle till the swing arm down to the
bottom and the lifting pads leave the vehicle chassis,
and then release the lowering handle.
zThe swing arms under the vehicle must be fully
shrunk

motor 2 is started, driving the oil pump 1 , sucking the
hydraulic oil from the oil tank into the oil cylinder 9, forcing
the piston rod move. At this time, the safety valve 5 is
closed.( the Max working pressure is already adjusted
before ex-factory. The safety valve can ensure the capacity
of the rated load, but when the pressure in the system
exceeds the limit, automatically overflow will be happened
inside safety valve to protect the hydraulic system).
Release the start button to stop the oil supply and the lifting
will stop. For lowering, first start Motor 2 to raise vehicle a
little, pull the steel ropes on two carriages to release the
safety lock mechanism, then press the lowering handle, the

zThis unit should be cleaned with dry cloth frequently
to keep it clean. Before cleaning, first switch off the
power to ensure the safety.
zThe working environment of this unit should be clean.
In case of dust in the working environment, it will
speed up the parts wearing and shorten the service
life of the lift.
Every day:
zBefore the operation, carefully check the safety
mechanism of the lift to ensure the electromagnet
suction and release action is proper, and the safety
plate is in good condition. When finding any abnormal
situation, make adjustment, repair or replacement
immediately.
zCheck to see if the steel cable connection is proper,
and if the tension is at the optimum status.
zCheck to see if the connection between hydraulic
cylinder and carriage is proper, if the connecting nut
between the steel chain and carriage is loose or
falling. Refer to Fig.6
Fig.6
Every month:
zRetighten the anchor bolts.
zLubricate chains/cables.
zCheck all the chain connectors, Bolt s and pins to
ensure correct installation
zCheck all the hydraulic lines for wearing
zCheck to see if the carriage and the inner side of the
column are properly lubricated. Use high-quality
heavy lubrication grease (lithium based lubrication
grease GB7324-87).
Note: All the anchor Bolt s should be tightened
completely. If any screw doesn’t function for some
reason, the lift can not be used until thebolt is
replaced
Every six months:
zCheck all the movable parts for possible wearing,
interference or damage.
zCheck the lubrication of all the pulleys. If the pulley
has dragging during the lifting and lowering, add
appropriate lubricant to the wheel axle.
zWhen necessary, check and adjust the balancing
tension to ensure the horizontal lifting and lowering.
zCheck the verticality of the column.
Note: The inner corner of each column should
be lubricated with lubricant, to minimize the roller
friction and ensure the smooth and even lifting.
Maintenance of hydraulic system:
zClean and oil change
In the six months after initial use of this unit, clean the
hydraulic oil tank and replace the oil, later clean the
hydraulic system once a year, and replace the oil.
See Fig. 7
zReplace the seal
After this unit is put into operation for certain period, if
finding the oil leakage, carefully check it; if the
leakage is due to the wearing of sealing materials,
immediately replace the worn one based on the
original spec. See Fig. 7
