Ground drawing showing the placement of two platforms (P1, P2) and the control box. Dimensions provided: 900mm, 616mm, 800mm, 1495mm, 2035mm. The control box can be placed on the left or right.
Note: The foundation of the lift platforms (P1, P2) must be concrete. If the inside level ground thickness is less than 150mm, the end of P1, P2 should be irrigated to an acreage of 2500×2500mm with a concrete thickness of ≥150mm. The basic thickness of concrete and leveling are crucial; do not expect the machine to self-level excessively. The lower parts of vehicle underbodies could interfere with structural parts of the lift, especially with sports cars. The lift can handle customized or non-standard vehicles within its maximum carrying capacity. A personnel safety zone must be defined for vehicles with unusual dimensions.
Chapter 3 SAFETY
Read this chapter carefully and completely, as it contains important information for the safety of the operator and others in case of improper use. This section explains risks, dangers, safety devices, and correct usage procedures to eliminate potential hazards.
⚠️ Lifts are designed and built to lift vehicles and hold them in an elevated position in an enclosed workshop. All other uses are unauthorized. Specifically, lifts are not suitable for: Washing spray work; Creating raised platforms for personnel; Use as a press; Use as an elevator; Use as a lift jack for lifting vehicle bodies or changing wheels.
The manufacturer is not liable for injury to persons or damage to vehicles or property caused by incorrect or unauthorized use of the lifts.
During lifting and descent, the operator must remain in the control station. The presence of persons within the indicated danger zone is strictly prohibited. Persons are permitted beneath the vehicle only when it is elevated, the platforms are stationary, and the mechanical safety devices are firmly engaged (e.g., safety gear is locked).
DO NOT USE THE LIFT WITHOUT PROTECTION DEVICES OR WITH PROTECTION DEVICES INHIBITED. FAILURE TO COMPLY CAN CAUSE SERIOUS INJURY AND IRREPARABLE DAMAGE.
Picture 6 shows a diagram of the lift with a clearly marked danger zone.
GENERAL PRECAUTIONS
The operator and maintenance fitter must observe safety regulations in force in the country of installation. They must always work in specified stations, never remove or deactivate safety devices, and read all safety notices. ⚠️ In this manual, safety notices are shown as follows:
- WARNING: Indicates unsafe operations that can cause minor injury to persons and damage to the lift, vehicle, or property.
- CAUTION: Indicates possible danger that can result in serious injury to people and damage to property.
- RISK OF ELECTRIC SHOCK: A specific notice for areas with a high risk of electric shock.
RISK AND PROTECTION DEVICES
Operators and maintenance fitters may be exposed to risks when a vehicle is on the raised platforms. Safety and protection devices are used to minimize these hazards. For optimal personal and vehicle safety, observe the following:
- Do not enter danger areas when vehicles are being lifted (Picture 6).
- Ensure the vehicle is positioned correctly (Picture 7).
- Lift only approved vehicles; never exceed specified carrying capacity, maximum height, or projection (vehicle length and width).
- Ensure no person is on the platforms during up/down movements or while stationary.
Picture 7 illustrates correct vehicle positioning.
GENERAL RISKS FOR LIFTING OR DESCENT
Safety equipment protects against overloading or engine failure. In case of overload, the overflow valve (Picture 8) opens and returns oil to the tank. Each oil cylinder is equipped with an antiknock valve that limits platform speed if an oil pipe bursts.
Picture 8 shows an overflow valve.
The safety tooth and gear module guarantee personnel safety beneath the machine in case of other protection failures. Ensure the integrity of the gear module and that the safety tooth is completely engaged (Picture 9 & 10).
⚠️ There should be nothing abnormal left on the safety modules to prevent the safety gear from engaging normally.
RISKS FOR PERSONNEL
This section highlights potential risks for operators, maintenance fitters, or any other person near the lift due to incorrect use.
RISKS FOR EXTRUSION
Personnel must leave the designated area without following rules during up and down operations. No person is admitted to work beneath the movable parts of the lift; work must be done in the safe zone (Picture 6).
RISK OF IMPACT (Picture 11)
Before starting up/down movements, ensure no personnel are inside the danger zone. If the lift is stopped at low elevations (below 1.75m), be careful to avoid impact with unmarked machine parts.
RISK OF FALLING OFF (PERSONNEL)
Personnel are prohibited from entering the platforms and vehicle during up/down operations to prevent falling off.
RISK OF FALLING (VEHICLE)
This can occur due to incorrect vehicle positioning, overweight, or incompatible vehicle dimensions. The vehicle engine must not be turned on when the platform is being tested. Nothing should be placed on the lift-lowering area or movable parts.
Picture 11 illustrates the risk of impact.
Chapter 3 SAFETY (Continued)
RISK OF SLIPPING (Picture 12)
The floor can become slippery due to lubricant contamination. The area around and beneath the lift, as well as the platforms, must be kept clean. Remove any oil spills immediately.
Picture 12 illustrates the risk of slipping.
RISK OF ELECTRIC SHOCK
Risk of electric shock from damaged insulation in electric equipment. Do not use water jets, steam solvents, or paint near the lift. Keep such substances clear of the electrical control panel.
RISKS RELATED TO INAPPROPRIATE LIGHTING
Operators and maintenance fitters must ensure all areas are properly and uniformly illuminated according to local laws. During operations, the operator should continually observe the lift and operate it only from the operator's position. When lifting/lowering, a cushion should be placed at the bottom of the chassis. Handling safety devices is strictly forbidden. Never exceed the maximum carrying capacity, and ensure vehicles are unloaded. It is essential to adhere scrupulously to all regulations regarding use, maintenance, and safety.

Check: Verify the locations of the two safety-pawl equipments are agile and reliable, check for oil leakage in the oil line, and ensure air tightness of the air loop.
Picture 21 shows a diagram of the control box with labeled components.
GROUND BOLTS INSTALLATION
Ground bolt installation must start after the concrete has cured sufficiently; otherwise, it will affect solidity. Adjust the parallel of the platform and the distance between the two platforms as Picture 4 requires. Fix anchor bolts using a percussion electric drill (Ø16 bit) to drill a 120 mm depth hole and clean it (Picture 22). Use a light hammer to install the ground bolts into the hole (do not install the central expanded nail until after level adjustment).
Picture 22 illustrates the ground bolt installation process.
Chapter 5 ADJUSTMENT (Continued)
Level adjustment
- Use a level bar and horizontal pipe to adjust the adjustment screws at the sides of the base plate.
- If platform unevenness is due to basic unevenness, use iron blocks to fill low spots.
- After level adjustment, insert the central expanded nail of the ground bolts and hammer it in.
- Screw down the ground bolt caps.
Picture 23 shows the base plate and ground connection.
⚠️ When the concrete curing period has not expired, the central expanded nail of the ground bolts cannot be installed. The gap between the base plate and ground after adjustment must be filled with iron plate or concrete.

③ The limit switch is not closed. | Check the limit switch, wires, and adjust or replace the limit switch. | |
In lifting operation, the motor runs, but there is no lifting movement | ① The motor turns reverse. | Change the phases of the power supply wires. |
② Lifting with light load is normal but no lifting with heavy load. | The set safe pressure of the over-flow valve may be increased by turning the set knob right ward slightly. | |
③ The amount of hydraulic oil is not enough. | Add hydraulic oil. | |
When press "Lower" button, the machine is not lowered | ① The safety pawl are not released from the safety teeth. | First lift a little and then lowering. |
② The safety pawl is not lifted. | The air pressure is not enough, the safety pawl is stuck, or the air pipe is broken off. Adjust pressure, check the air pipe, and replace it. | |
③ The solenoid air valve does not work. | If the solenoid air valve is energized but does not open the air loop, check or replace the solenoid air valve. | |
④ The descent valve is energized but does not work. | Check the plug and coil of the descent valve and check the right turn tightness of its end copper nut. | |
The machine lowers extremely slowly under normal loads. | ① The hydraulic oil has too high viscosity or frozen, deteriorated (in Winter). | Replace with hydraulic oil in accordance with the instruction book. |
② The “antiknock valve” for preventing oil pipe burst is blocked. | Remove the “antiknock valve” from the oil supply hole at the bottom of the oil cylinder, and clean the "antiknock valve". | |
The right and left platforms are not synchronous and not in the same height. | ① The air in the oil cylinder is not vent completely. | Refer to "Oil Make-up adjustment". |
② Oil leakage on oil pipe or at its connections. | Tighten oil pipe connections or replace oil seals and then make-up oil and adjust levelness. | |
③ The "stop valve" can not be closed tightly and almost make-up oil and adjust every day. | Replace oil "stop valve" and then make-up oil and adjust. | |
Noisy lifting and lowering. | ① Lubrication is not enough. | Lubricate all hinges and motion parts (including piston rod) with machine oil. |
② The base or the machine is twisted. | Adjust again the levelness of the machine, and fill or pad the base. |
