WARNING
z This instruction manual is an essential integral part of
this product. Please read all instructions.
z Properly keep this manual for use during the
maintenance.
z This equipment is only used for its clearly designed
purpose, and never use it for other purposes.
z The manufacturer is not responsible for any damage
caused by improper use or other purposes of use.
PRECAUTION
z Only the qualified personnel having undergone
special training can operate this machine. Without the
permission of the manufacturer or not following the
requirement of the manual, any changes in the
machine part and in the usage scope may cause
direct or indirect damage to the machine.
z Don’t keep the lift in the extreme temperature and
humidity environment. Avoid installation beside the
heating equipment, water tap, air humidifier or stove.
z Prevent the lift from contacting large amount of dust,
ammonia, alcohol, thinner or spray adhesive, and
prevent it from rain shower.
z During the machine operation, non-operators should
be kept away from the machine.
z Inspect machine daily ,do not use lift with damaged
parts or being damaged .Use original components to
replace damaged parts
z The lift can’t be overloaded. The rated load of the lift

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.

5. Repair and Maintenance
Keep clean
z This unit should be cleaned with dry cloth frequently
to keep it clean. Before cleaning, first switch off the
power to ensure the safety.
z The 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:
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.
Maintenance of hydraulic system:
z Clean 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.
z Replace 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

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.
