cycle is closed. Small scissor main high pressure valve 4 is opened, deputy valve is turned off (to open valve
counterclockwise, clockwise to turn off) If lifting hydraulic system failure or power outage, need to use the Jack
to move the insurance top gear, chocked with object to avoid insurance teeth meshing in the descent, then
rotate emergency back-port 12 to lowering the Small scissor lift. Then rotate emergency back-port 11 to
lowering the big scissor lift. System for lowering speed can be adjusted by adjusting the throttle valve 13.
During the adjustment process and adding oil, the operator should be careful.
Hydraulic oil leveling:
To fill oil to slave cylinder of the big scissor, open the deputy valve and close main high-pressure valve 5,
then push the big scissor's up button to filling and adjusting. If too much oil is added, press the DOWN button
to discharge oil to ensure the two platforms at same height. To fill oil to slave cylinder of the small scissor, open
the deputy valve and close main high-pressure valve 4, then push the small scissor's up button to filling and
adjusting. If too much oil is added, press the DOWN button to discharge oil to ensure the two platforms at
same height. After finishing the adjustment, open the main cycle and turn the subsidiary off.（see fig4）

4.2 Unpacking
The lift is delivered in three separate boxes: 2 platforms (with hydraulic hoses) and 1 control desk.
Unpack according to the instructions on the packages. Remove the packing materials and check for
damage and loss of components.
To avoid accidents from occurring, keep the packing material away from children. The packing materials
need to be disposed of properly if they may contaminate the environment.
5. Equipment installation
5.1 Basic requirements
yThe lift can only be installed on concrete floor with a minimal thickness of 200mm（7.9″），and at least
7 days of solidification time.
yThe strength of the concrete ground should exceed 3000PSI（2.1kgf/mm2）。
yThe tolerance of the concrete floor levelness should not exceed 5mm（0.2″）。Slight slope can be
corrected with shims. Excessive slope on the ground will greatly affect the performance of the lift. In
this case, new concrete slab should be made.
yInspect for possible hindrance such as low ceiling, overhead pipelines in the work area, passageways
and escapes. The working area of the lift should be 4.2M（165.4″）high to give enough space.
yAllow enough space（at least 2M（78.7″））at the front and back of the lift so that operation should not
be hindered. (see fig6)
yPower supply: Put the power source in place before installation. All the wiring should be performed by a
qualified electrician.
5.2 Installation Procedures
5.2.1 Tunnel Installation
Tunnel positioning mode is the same as the normal positioning，but tunnel positioning is more difficult
than the usual ones because to avoid cars slipping, the hanging plates hidden component need to be
replaced. Tunnel size see fig 6, normally only few people install the lift without the hanging plates hidden

Warnings ：
♦The depth of the pits should over 200mm，The strength of the concrete ground should
be great than 3000PSI（2.1kg/mm2），and the tolerance of the concrete floor levelness
should not exceed 5mm（0.2″）。

6 Operation
6.1 Inspection before operation
zCheck for the synchronized and steady movement of the platforms.
zCheck the sensibility and reliability of safety ratchet.
zReview the platforms reach the highest position ( 1850mm 72.8 ), the platform will automatically stop
rising
zCheck if two small platforms up and down movement is consistent and smooth
zCheck when small platforms rose to the highest position（450mm 17.7″），whether the platform is
automatically stopped rising
zView cylinders, tubing and connectors with or without leakage
zCheck solenoid valve, air cylinder, pressure - regulating valve, connector has no leakage phenomenon
zCheck the motor, gear pump operation sound is normal
zCheck the slide plate for proper action
zCheck the emergency stop button is working correctly
6.2 Operational Procedures
zVehicle into the lift machine speed should be kept under 5km/h, confirm that the slide latch plates are
plugged in.
zWhen the vehicle is stopped, the front wheel is located at the centre of the turn plates, pull your hand
brakes
zPress the up button, rise the vehicle to 200mm~300mm (7.9″～11.8″)
zCheck whether the vehicles and lifting machine level and have no abnormal state。
zContinue pressing the up button, to lift the vehicle up to its required height。
zPress the lock button，bring down the platform，safety gear meshing and keep the platform level on both
sides
zPress the small scissors lift button to remove the tire
zCheck there are no foreign objects around or below the lift before start to repair and maintain the vehicle,
make sure there is no abnormal state and then press the down button; lowering down to the initial
position.
6.3 Safety Precautions
zThe hydraulic relief valves are well-adjusted before leaving factory. The manufacturer will not be
responsible for any damage caused by unauthorized adjustment.
zCheck the safety lock ratchets are engaged before going about any under-car jobs
zBefore the small scissors lift the vehicle up, suitable pad must be selected. Place rubber pads on the
platforms and spread them for maximal support.。
zIn case of any leakage in the hydraulic system, fix the problem and refill the oil to the proper level.
zWhen you press the lock button，after the safety gear on both side meshing，immediately release the
button，otherwise the cylinder back oil will be too much. After the completion, press the lowering button
(big scissor), circuit settings for the cylinder cannot supply enough oil to make the platform rise to
disengage the safety gear. At this point, platform could not be descended or only one side of safety gear
disengaged, and the other side still engaged, which leads to only one platform descended, and the
vehicle will rollover. (See hydraulic schematic diagram)

7.1 Preparations
zMove the contact surface of in roller filling in 2# lithium grease, from left to right scrolling surface evenly.
zAdd 2# lithium grease at the joints of the machines.
zFill up the tank with hydraulic Oil N32 or N46（Depending on the season and the local temperature）
7.2 Adjustment Procedures
zCheck if all the connection bolts are tightly fastened
zIf there is air in hydraulic system due to new installation, air bleeding performance is needed. The air in
the master cylinder can be bled after the platform goes up and down several times. The air in the slave
cylinder can be bled out by following steps: lift master platform close to the maximal height; adjust the
main high-pressure valve until it is turned off, open the deputy valve; press the UP button to raise the
slave platform reaches near the maximal height, press the DOWN button to lower slave platform to the
bottom. Repeat three more times, all the air in the slave cylinder can be bled after the operation.
zAdjust the amount of auxiliary engine oil, to let the platforms stop at appropriate height。
zTurn the high-pressure valve to working status.
zPress UP button, the platforms begin to raise, release the UP button, the platforms stop moving. Press
the safety lock button, scissor lock down. Then, press the DOWN button, the platforms will raise a little to
disengage to safety claw, meanwhile the safety cop is opened, lift will be lowered.
zThe same operation on the small platform.
zAdjust position of the mounting plate equipped with a limit switch make sure the platforms up to the
proper height, limit switch is triggered, pumping station stop working; cutting off cylinder oil, platform stop
rising and thus play a role in protecting the machine.
Notice：
zAttention should be paid to the position of oil pipes and hydraulic hose when the platforms move to the
minimal height for the first time. Make sure they do not get stuck with platforms moving downwards.
zWhen bleeding the air in the slave cylinder, do not lift Master Platform to the maximal height. Otherwise,
the limit switch is triggered, the power will be cut off and Slave Platform can't move.
zWhen bleeding the air in the slave cylinder lift Slave Platform to highest position, and then release the UP
button. Otherwise Oil pressure may damage the hydraulic cylinder
