Car lift load operation
1) After driving the car onto the work platform, the brake brakes are tightened and the driver is evacuated from the work platform.
2) The anti-slip support is reliably placed on the front and rear of the car tire.
3) In the non-supply state, press the up button to raise the work platform to the desired height.
4) Jog the descent button so that all four hooks are reliably supported on the hanging plate before entering the work area for maintenance or adjustment work.
5)  After the repairing or adjustment work is completed, jog the up button, turn the reversing valve to the air supply position, so that the four hooks are off the hanging plate, press the down button, and the working platform is lowered.
6) When the work platform is lowered to the lower limit position, the anti-slip support is removed and the car is driven away from the work platform.

Precautions for use
1) Special personnel shall be provided to operate, maintain and repair the lifting equipment. It is forbidden for those who have not read this manual and who are not qualified to operate the lifting machine without authorization.
2) The car should be parked so that its center of gravity is close to the center of gravity of the work platform.
3)  Overload operation is strictly prohibited.
4) During the lifting process of the work platform, no one may remain on the work platform or under the work platform.
5) Do not operate the unit under fault conditions.
6) Only after determining that four safety hooks are attached can a person enter the work area.
7) The car that stays on the work platform must tighten the hand brake and pad the anti-slip support.
8) When the lift is not in use, it should be lowered to the lowest position and the power supply should be cut off.
9) After the lift is used for a period of time, the wire rope will be stretched to varying degrees, causing the work platform to be uneven and the four hooks not to be synchronized. In this case, the length of the wire rope should be adjusted in time.

Hydraulic tank
1) Hydraulic tank oil level: The oil level should be checked by oil mark for each shift.
2) Replacement of hydraulic oil: After the equipment is activated for three months, change it once every year. After changing the oil, first clean the fuel tank and then inject the No. 30 hydraulic oil.
3) Set pressure of the safety valve: Check once a year, unscrew the screw plug on the seat of the fuel tank and install the pressure gauge to observe. After adjustment, lock the safety valve (the pressure gauge is self-contained).

Adjustment of the length of the wire rope: Check the equipment once after one month, and check it once every quarter. After adjustment, lock the adjusting nut.

1) When the work platform is at the lowest position, the wire ropes in the four columns must be tightened.
2) The four safety hooks should be hooked into the square hole of the hanging plate synchronously.
