The centre-of-gravity position of each kind of vehicle is different. First know about the centre-of-gravity of vehicles. Make the
centre-of-gravity close to the plane formed by the two columns when the vehicle drive into the lift. Adjust the lifting arm, make
the bearing point support the bearing surface of vehicles.
4 Safety instructions

button after the machine is lifted, vehicle maintenance can be permitted.
-If the two carriages are not in the same plane, adjust the nut on steel cable to keep them in the same plane.
Tighten the steel cable, or the two carriages can not be synchronous.
-Locking devices are installed in each lifting arm, it can lock automatically when lifting arm rotate to any needed
angle. When the carriage in the lowest position, the lifting arm can rotates freely. In order to prevent the lifting
tray from falling, we adopt the adjustable thread lifting tray to make it more safe and convenient
Risk for extrusion
During up and down operations, personnel leave the said area without following the rule and instruction.
During up and down operations, no person is admitted to work beneath the movable parts of the lift, should work
in the safe zone.
Risk of impact
Before the operator begins up and down movements, make sure that there are no personnel inside the danger
zone. When, due to operational reasons, the lift is stopped at relatively low elevations (lower than 1.75m above
the ground) personnel must be careful to avoid impact with parts of the machine not marked with special colors.
Risk of falling (vehicle)
This hazard may arise in the case of incorrect positioning of the vehicle on the lifting arms, overweight of the
vehicle, or in the case of vehicles of dimensions that are not compatible with the capacity of the lift.
When the lifting arm is being tested, the vehicle engine can not be turned on.
There is nothing should be placed on the lift-lowering area and the movable parts of the lift.
Risk of slipping
The floor caused by lubricant contamination of around the lift. The area beneath and immediately surrounding
the lift and also the platforms must be kept clean. Remove any oil spills immediately.(
