Risks related to appropriate lighting
The operator and the maintenance fitter must be able to assure that all the areas of the lift are properly and
uniformly illuminate compliance with the laws in force in the place of installation.
During up and down operations, the operator should continually observe the lift and can operate it only in the
position of operator. When lifting and lowering the vehicle, the cushion needs being put in the bottom of chassis.
The handling of safety devices is strictly forbidden. Never exceed the maximum carrying capacity of the
lift, make sure the vehicles to be lifted have no load.

5�2 Drive principle
• Press button “UP”, the contactor and motor work. Motor drives the gear pump,
the hydraulic oil goes through the one-way valve, oil hose finally reach the in the
downward cavity of oil cylinder. The piston rod is pushed by the oil pressure. The
oil cylinder drives the lifting arm synchronously with the steel cable and roller
wheel and chain.
• To do the vehicle maintenance, operators press the “LOCK” button, the lowering
solenoid valve works and the electromagnets do not work when the carriage is
locked.
• To lower the lift, press the “DOWN” button, the time relay works, the lift raises
for 2-3 seconds and lowering solenoid valve works at the same time. The weight
of vehicle and lift extrude the hydraulic oil into the oil tank. Finish the lowering
operation.

7. Installation
7.1 Installation requirement
-Two post lift must keep install under the safe distance requirement from the wall, column and other equipment.
Minim distance from wall is 800mm, consider the urgency situation and convenience work, the distance of exit
passageway should considered having enough rooms.
Please make sure there is power supply for the control unit.
The indoor height should not be less than 4500mm.
Indoor ground is available for installation, only the ground level meets the installation requirement and have enough
endurance capacity (concrete intensity must be higher than 21MPa, concrete thickness must reach 300mm and
above), otherwise, please pour concrete 1200 * 4000mm in installation space, thickness must reach 300mm and
above.
