OVERVIEW OF THE LIFT
2.1 General descriptions
This full rise scissor lift is of pretty lower profile when at its lowest position. Its four cylinder structure makes the lowest 110mm clearance
from ground come true. Currently this model is designed with two different leveling systems-auto leveling and manual leveling. For it is
specially designed for surface mounting, users could have it installed with great convenience. Its platform extension deign may not only be
used as a ramp, but also can serve as an extended part of the platform for much longer vehicles. Besides, designs like, 24V working
voltage of control box and limit switch, alarming buzzer, pneumatic safety lock, anti-surge valves, etc have fully considered your personal
security.

INSTALLATION INSTRUCTIONS
3.1 Preparations before installation
3.1.1 Tools and equipment needed
√ Electrical drill
√ Open wrenches
√ Screw drivers
√Adjustable spanner
3.1.2 List for parts checking ---Annex 1（Packing list）
Unfold the package and check if any parts missed as per Annex 1. Do not hesitate to contact us in case any parts missed, but if you do not
contact us and insist installing upon the lack of some parts, every lift as well as our dealers will not bear any responsibility for this and will
charge for any parts subsequently demanded by the buyer.
3.1.3 Ground conditions
The lift should be fixed on a smooth and solid concrete ground with its strength more than 3000psi, tolerance of flatness less than 5mm
and minimum thickness of 200mm. In addition, newly built concrete ground must undergo more than 28days’ cure and reinforcement.
3.2 Precautions for installation
3.2.2 Joints of oil hose must be firmly connected in order to avoid leakage.
3.2.3 All bolts should be firmly screwed up.
3.2.4 Do not place any vehicle on the lift in the case of trial running.
3.3 Installation
Step1: Remove the packages and place the lift as per the following drawing.
≥7.87 inch

Step2: Connect oil hose
(This step is extremely important, so do refer to the diagram for of oil hose connection and understand the following
instructions before proceeding)
1. make sure there is nothing obstructed or dirty left in the hose.
2. Installers have to distinguish where the chief oil hose to be connected by referring to the below two pictures and have the chief hose
connected.
3. See the left picture followed by; two branches of the chief oil hose are going to be respectively connected to the tie-ins for chief oil
hose reserved on the hydraulic block and the other scissor. Similarly, branches of the other two leveling hoses are going to be connected
to the tie-ins reserved for leveling hoses.
4. Check if all connections are tightened.
Concrete thickness
≥7.87 inch
Control cabinet
Technical requirement:
1.concrete type 425#, 25 days’ drying period
2.concrete thickness ≥7.87 inch
3.evenness ≤0.2 inch
4.thickness and evenness of the concrete is very crucial.

Step3: Connect the wiring and air system
Connect exterior wires as per the wiring diagram, with the black for phase wire, the blue for null wire, and the green -yellow for grounded
conductor.
Connect the compressed air supply to the air inlet of the air pump and then have the air hose (Ф10×Ф7mm, prepared by the user) of the
pneumatic safety lock connected to the air outlet of the pump.
Attention：Pressure of the air supply should be among 0.6-0.8kg/cm2

Step4: Fill with hydraulic oil
Pour into the oil tank with 16liters of anti-grinding oil. Level of the oil shall be 10mm to 40mm away from the top of the tank. (Users can
measure it by the feeler attached on the lid)
Step5: Leveling
Attention: Level the platforms before connecting height limit switch because if not, platforms can not rise to the highest position.
Before leveling, make sure the oil hoses are correctly connected. Otherwise, oil cylinders may not work synchronously or could be
damaged. In addition, operators need to know clear which leveling valve controls which platform. This could be judged by the way that
the oil hose was connected or by trial raising or lowering.
Manual leveling
Open one of the leveling valves and press the UP button to supplement oil to the oil hose connected. Close the valve to stop adding oil. In
normal working condition, both leveling valves are closed. If both valves are open, two platforms of the lift can still rise but will not move
upwards synchronously.
A. Both valves open B. Both valves closed：Normal working

C D.
One valve open, the other closed: leveling condition
A.1. Open both leveling valves and press the UP button to have both platforms raised to the highest positions. Repeat this step for two or
three times. (Take care that this step could be time consuming, because there’s air in the cylinders and no load on the platforms.)
A.2. Close both leveling valves as per drawing B. Press the UP button to see if both platforms rise synchronously. (Normally, till now the
platforms may not rise synchronously.)
A.3. If not work synchronously, one platform may rise faster than the other. Users should first judge which leveling valve controls which
platform and then open the valve that controls the slower-rising platform to supplement oil into its oil hose. Press the UP button to make
both platforms rise to the same height. (The other valve here must be closed.)
A.4. Close both leveling valves. Press DOWN I button to have both platforms lowered to the lowest position.
A.5. In case they do not lower synchronously, open the valve that controls the slower-lowering platform and press DWON I button to have
them lowered to the lowest position and then close the leveling valve. If the lift is equipped with a height limit switch, press DOWN II
button when platforms stop lowering at a height of 500mm from the ground.
A.6. After both leveling valves having been closed, press the UP button to check if both platforms rise synchronously.
A.7. Repeat doing step A5 and step A 6 until synchronization achieved.
Step6: Connect the limit switch
Connect the wires reserved for limit switch and fix its protection cover with screws.
Step7: Fix expansion bolts.
1. Drill anchor holes for expansion bolts on the ground with an electrical drill. Make sure to drill vertically.
2. Remove thoroughly the debris and dust in holes and ascertain that the posts stay right upon the circle previously marked by chalk.
3. Hammer in and secure expansion bolts.

6.1. Daily checking items before operation
The user must perform daily check. Daily check of safety system is very important –the discovery of device failure before action could save
your time and prevent you from great loss, injury or casualty.
·C heck whether oil hose well connected. No leakage is allowed.
·C heck the electric connections, make sure all connections are in good condition.
·Check whether the expansion bolts well anchored.
·Check if safety teeth and safety block matched well or not.
6.2. Weekly checking items
·C heck the flexibility of moving parts.
· Check the working conditions of safety parts.
· Check the amount of oil left in the oil tank. Oil is enough if the carriage can be raised to highest position. Otherwise, oil is insufficient.
·Check whether the expansion bolts well anchored.
6.3. Monthly checking items
·Check whether the expansion bolts well anchored.
· Check the tightness of the hydraulic system and screw firm the joints if it leaks.
·Check the lubrication and abrasion circumstance of moving parts.
6.4. Yearly checking items
·Empty the oil tank and check the quality of hydraulic oil.
·Wash and clean the oil filter.
If users strictly follow the above maintenance requirements, the lift will keep in a good working condition and meanwhile accidents
could be avoided to a large extent.
