GENERAL SAFETY RULES

1. Reading the operation manual before using the machine, only trained people

allowed to operate.

2. The air inlet hose attached to Oil filter should capable of 0.6-0.8Mpa, also

reach 3 times of explosion pressure.

3. Avoid freezing if operate the machine below 10 degree, compressed air is not

allowed to use until filtered.

4. Clear surrounding of lift when raise or lower.

5. Driver should leave car when raise.

6. The machine should be used within its capacity.

7. Brake the vehicle when raise.

8. Keep eyes on the two platforms when raise. Stop raising if two platforms are

not at the same level. Continue using the machine after checking.

9. Switch off when vehicle raises to desired height, safety teeth locked.

10. The lift raises a little when press DOWN button, to release safety lock.

11. Switch off if leave the machine idle for a long time. Cut off the electricity.

12. Fire fighting device is necessary in the place the machine installed.

13. Anti-explosion valve in cylinder is used to avoid fast lowering because of oil

pipe explored or leaked.

INTRODUCTIONS INTENDED USE: The full rise scissor lift is suitable for lifting vehicles with maximum total weight of 3000kg, up to a maximum height of 1700mm

from ground.

This appliance must be only used for the purpose of which it is expressly designed. It is forbidden to lift people or others not

specified in this manual. Any other use is to be considered improper and irrational and thus highly forbidden. The constructor

cannot be held responsibilities for any damage or injuries caused by an improper use or by the non-observance of the following

instructions:

The lift, in its standard version, is not intended for outdoor use, in this case, it is necessary to ask the constructor for a special

version.

You will see the Motor, pump, cylinder, valves and integrate circuit when you open the control unit.

Throttle valve (B) is used to adjust the lowering speed of the lift，and adjust raising speed by changing openness of Throttling

cutoff valve (E).

The Overflow valve (A) is adopted to adjust the system pressure within 23Mpa, which has been rated by manufacturer.

HYDRAULIC OIL REFUELING Refuel 16L hydraulic oil with number of L-HM32. It is suggested to make oil level lower than 10cm to top of oil tank and higher

than 40mm to the bottom.

PIPE AND WIRE CONNECTING Locate the high pressure rubber pipe as Fig7 and Fig 8. showing, then connect the No. 0 and 10 of short wires onto terminal

board. Press “UP” button to lift the platforms a little then connect the limitation switch and air hose. See Fig 9.

Fig 9.

NOTE: Disconnect No. 0 and No. 10 short wires when install limit switch, then connect limit switch with No. 0 and No.

10 short wires.

COMMISSIONING REFUEL AND EXHAUST THE CYLINDERS Connect with power source, turn on power switch on control cabinet.

Press UP button, checking running of motor. Make sure that the rotating of motor is anticlockwise, if not, cut off power source

then change the inlet orders.

If the motor works in right way, commissioning follows.

Refer to Fig 8, Turn anticlockwise the throttling stopping valve E to open the valve, and turn off Refueling stopping valve D

anticlockwise.

Press UP button to raise one side platform about 1M high, then press DOWN button to lower this side platform to bottom. Raise

again this side to 1.4M high, then lower to bottom.

Turn clockwise the throttling stopping valve E to close the valve, and turn on Refueling stopping valve D clockwise 90 degree.

Press UP button to raise the other side platform about 1M high, then press DOWN button to lower this side platform to bottom.

Raise again this side to 1.4M high, then lower to bottom.

Repeat this step 5~6 times, keep the two sides platforms at same height.

Turn off Refueling stopping valve D, open Throttling stopping valve E to make two platforms work together.

MOUNTING THE BASE FRAME Lock the safety catch in the same safety teeth and adjust the distance according to the Fig 3 showing.

Fix the anchor bolt (M16X120, 8pc) with electrical impact (ф16 drill bit).

Adjust the height of bolt of base frame to ensure the level error between two platforms not less than 5mm.

Filled the base frame with concrete or steel plate, then hammer the expansion bolt to anchor tightly the frame with ground.

Fig 10.

12 - 16

COMMISSIONING Check the limit switch, oil and air system. Make sure that the base frame is tight enough.

Operate the equipment 2~3 times without loading.

Raising and lowering with loading, 3000kg, 2~3 times, put it into work if everything is fine.

OPERATION

GENERAL PRECAUTIONS WHEN USING.

1. Check all the pipelines and joints before use. The machine only can be used after there is not any leakage.

2. Clear the surroundings of the lift before operation.

3. The driver and passengers are not allowed to stay in the being serviced vehicle.

4. The machine shall not lift or lower an automobile if the center of gravity of automobile is not within the supporting range

of the supporting device. Otherwise, the manufacturer will not bear any responsibility for the consequence resulted from

the operation above mentioned.

5. The staff or operators shall be in a safe position when the machine lift or lower.

6. When the lifter lifts the automobile to a desired height, first of all, the main switch must be turned off before the

automobile is repaired so as to prevent non-operator or unauthorized person from pressing the start switch.

7. The lift should descend to its lowest point and power of the machine should be cut off if it will not be used in long time.

OPERATION:

Turn the main power switch and the machine will get into normal working state.

Please refer to the left diagram of control panel

“UP” and “DOWN” button on left are for lifting and lowering

the machine.

Fig 7.

NOTE: Drive the vehicle onto the lift and ensue the body is well centered to the runways.

Driver leaves the vehicle.

EMERGENCY OPERATION If in case there is electricity failure during operation, lower the vehicle as instruction below:

1. Cut off the power supply to avoid the unexpected power input.

2. Lift up the safety lock by jack and other standby tools and insert some objects,

like rigid paper, into the safety blocks.

3. Open the control unit.

4. Unscrew the yellow stud (G) of Electromagnetic Unloading valve (F) to lower the vehicle.

5. Screw off the stud after lowering the lift..
