3. Operation Description
3.1 Precautions for vehicle repair
work
z Different 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. Please refer to ALI / LP
Guide（PGP-25）standard to get the advised
vehicle lifting point.
z Cautiously note the car roof position when lifting,
to avoid its contacting with top beam and
causing accident.
z Carefully read the warming symbol.
z The 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.
z Based on the production needs, some
specifications in the instruction manual are
subjected to change without notice
3.2 Preparation before Operation
z Lubricate contact surface of the carriage with
general-purpose lithium grease（GB7324-87）.
All sliding surface should be coated evenly from
the top to bottom.
z Fill hydraulic oil N32 or N46（approx.12L） to the
oil reservoir of the power unit.
3.3 Lifting the Vehicle
z Keep work area clean, don’t operate the lift in
cluttered work area.
z Lower the carriage to the lowest position.
z Reduce the swing arm to the minimum length.
z Swing the arm along the route of the vehicle
z Move the vehicle to the location between the two
columns
z Swing 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
z Press the UP button on the electric control
box(Fig.4), slowly lift the vehicle to ensure the
load balance, and then raise the lift to the
required height.
z Release the UP button and the carriage will
stop.
z Press 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.
3.4 Lowering the Vehicle
z Clean the work area before lowering the vehicle.
z Lift vehicle of 5-10mm.
z Pull the safety lock handle, then press down the
lowering handle(Fig.4),the carriage lowers
z Lower the vehicle till the swing arm down to the
bottom and the lifting pads leave the vehicle
chassis, and then release the handle.
z The swing arms under the vehicle must be fully
shrunk。
Note: Don’t operate lift if the safety latch
doesn’t work, which means the safety latch must fall
into the safety groove when lifting. Don’t operate lift
when the load is tilting.

z Check to see if the connection between hydraulic
cylinder and carriage is proper.
z Check to see if the steel cable connection is proper,
and if the tension is at the optimum status.
Every month:
z Retighten the anchor Bolt s.
z Lubricate chains/cables with lithium based lubrication
grease（GB7324-87）
z Check all the hydraulic lines for wearing
z Check 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 the Bolt is
replaced
Every six months:
z Check all the movable parts for possible wearing,
interference or damage.
z Check the lubrication of all the pulleys. If the pulley
has dragging during the lifting and lowering, add
appropriate lubricant to the wheel axle.
z When necessary, check and adjust the balancing
tension to ensure the horizontal lifting and lowering.
z Check 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.

Working principles of hydraulic system:
When the button is pressed to start the motor on the
power unit, the motor 2 will be actuated to put the oil pump
1 into motion; and oil will be sucked from the oil tank and
sent to cylinder 9 forcing the piston move upward. At this
time, the safety vale 5 is closed. (The pressure is well
adjusted before leaving the factory to ensure the rated
capacity. However, when the system pressure exceeds the
limit, the oil will automatically overflow). When the start
button is released, the oil supply will stop so as to stop the
lifting. For lowering the carriage, first start up the motor to
raise the carriage a little, pull the safety lock handle on the
column to disengage the safety locking status; and then
press the manual lowering handle valve 6 to lower the
carriage.

2.2 Principles of equipment
z Lifting mechanism: Each of the two columns
has one hydraulic cylinder respectively. When
the power unit works, the hydraulic oil gets into
the lower chamber of the cylinder, forcing the
piston rod moves upward and drive the
carriage moving upward .
z Supporting mechanism: When the vehicle
enters into the working area, adjust the
position of two-stage telescopic swing arms to
make the lifting pad near the correct lifting
point of the vehicle, and then adjust the screw
height below the pad to adapt to different
heights of vehicle chassis.
z Balancing mechanism: To keep the balance
during the lifting and lowering process, the lift
uses two steel cables to interconnect two
carriages, forcing the carriages to rise and
descend synchronously. If the carriages and
swing arms are not on the same level, adjust
the screw at the end of the steel cable, making
the swing arms at the same level (equal
position from the floor). At this time, the steel
cables must be adjusted tightly with equal
tension, otherwise the equalization can’t be
ensured.
z Manual safety lock system: Two safety plates
are installed on each of the column and safety
boards are welded on the back of the carriages.
When the carriages rise, safety boards will go
up and push against the safety plates .When
the carriages stop, the safety plates will get
into the slot of the safety boards to prevent the
carriages from lowering; when lowering the
carriage, lift carriages a little to disengage
safety plate and then pull the lowering handle
on power unit to lower the carriages
z Safety lock scope: The effective travel range of
safety lock mechanism is from 470mm to
1900mm,the distance between the lifting pad
and ground.
z To prevent the vehicle slip, the swing arm is
installed with positioning mechanism, making
the swing arm capable of automatic locking
during operation.
3. Tools for installation and adjustment
To ensure proper installation and adjustment, please prepare the following tools:

4. Unpacking
z Open the packing box; remove the packing
materials and inspect the lift for any sign of
shipment damage. Check packing list to see if the
main parts and accessories are complete.
z Keep the packing materials away from the children
to avoid danger; if the packing materials cause the
pollution, they shall be treated properly.
5. Installation
5.1 Important notice
z The wrong installation will cause the lift damage or
personal injury. The manufacturer will not
undertake any responsibilities for any damage
caused due to incorrect installation and usage of
this equipment, whether directly or indirectly.
z The correct installation location shall be
“horizontal” floor to ensure the horizontal lifting.
The slightly slope floor can be corrected by proper
shimming. Any big slope will affect the height of the
lifting pad when at the bottom or the horizontal
lifting. If the floor is of questionable slope, consider
a visual inspection, or pour a new horizontal
concrete slab if possible. In short, under the
optimum horizontal lifting status, the level of the
lifting relies on the level of the floor where it is
installed. Don’t expect to compensate for the
serious slope.
z Don’t install this lift on any asphalt surface or any
surface other than concrete. The lift must be
installed on concrete conforming to the minimum
requirement showed in the manual. Don’t install
this lift on the concrete with seams or crack and
defect. Please check together with the architect.
z Without the written approval of the architect, don’t
install this lift on a second floor with basement.
z Overhead obstruction: The lift installation area
can’t have any overhead obstruction, such as
heater, building support, electrical pipe, etc.
z Concrete drilling test: The installation personnel
can test the concrete thickness at each site by
drilling test. If several lifts are installed at one place,
it is preferred to make drilling test in each site
z Power supply: Get ready the power supply before
the installation. All the electric wiring and
connecting should be performed by a certified
electrician.
5.2 Installation procedure
5.2.1 Selecting installation site
Select installation site based on the following conditions:
z Lift can only be installed on concrete slab, which
must have a minimum thickness of 250mm and
should be aged 7days at least .
z The concrete slab shall have reinforcement by steel
bar.
z The concrete slab must be leveled.
z If the thickness of the whole ground concrete is
greater than 250mm, the lift can be installed directly
z Check the possible obstruction, e.g. low ceiling, top
pipeline, working area, passage, exit, etc.
z The front and back of the lift should be reserved
with sufficient space to accommodate all the
vehicles(Fig.4).

The electrical working principle is as follows:
Press the start button (SB), motor (M) is energized to
drive the gear pump supplying oil to push the carriage
upward; release the start button SB, the motor (M) will lose
the power and the carriage will stop rising. if the vehicle is
lifted up to the top and contacts the limit switch (SQ) on the
top beam, the motor (M) will lose the power, the carriage
will stop lifting to protect the roof.

Working principles of hydraulic system:
When the button is pressed to start the motor on the
power unit, the motor 2 will be actuated to put the oil pump
1 into motion; and oil will be sucked from the oil tank and
sent to cylinder 9 forcing the piston move upward. At this
time, the safety vale 5 is closed. (The pressure is well
adjusted before leaving the factory to ensure the rated
capacity. However, when the system pressure exceeds the
limit, the oil will automatically overflow). When the start
button is released, the oil supply will stop so as to stop the
lifting. For lowering the carriage, first start up the motor to
raise the carriage a little, pull the safety lock handle on the
column to disengage the safety locking status; and then
press the manual lowering handle valve 6 to lower the
carriage.
