1. Safety instruction and attentions 1.1 Cautions with words

Pay special attention to the parts connected with product safety. Here are some examples:

If there is this signal before any passage, it means that operation like this is wrong and will lead to big casualty or heavy damage to the device.

The figure appearing before passage shows that it is not allowed to operate according to the passage, or the potential risk will develop into big casualty and heavy damage to the lift. The passage besides this signal lists the notice points and security requirements during the process of normally using, maintenance and care of the lift.

1.2 Safety caution signal

Please read Safety Signage carefully, understand and remember them.

Only trained person can operate and

use the lift.

Never let non‐trained personnel come

in contact with Lift.


2

It’s suggested by the manufacturer that the raising position should be the points of support.

When install and move some big or heavy parts on the car during the maintenance, bracket should be used to keep the car’s balance.

Use the high bracket if necessary.

Supplementary bracket will reduce the heavy burden of the car on the lift when rise.


3

Clear area if vehicle is on danger of falling.

Center of gravity of the car should be at center of arms’ acting force.

Keep away from the working area when raise or drop vehicles.

Forbid to rock the car during lift’s rising and lowering.


4

Don’t modify any controlling parts or mechanical parts of the lift privately.

Keep feet clear of lifting when lowering. Avoid pinch points.

1.3 Using Purpose

The lift is used to lift vehicles whose weight is less than 4 ton. Other usages are not allowed.

1.4 Expected Rated Lifted Assignment

In principle, the lift we design supports double direction placement of the car, however, it’s better to use the short arm to support the motor end, because in this case there will be less wear and tear for the lift 1.5 Attentions ⅰ. Operators should read the manual carefully to avoid accidents. ⅱ . Operators should be familiar with all functions and operating

methods of the lift.

ⅲ. Check before operating and regular check must be carried out too. ⅳ. If there is any abnormal sound during rising and lowering, stop to use

the lift. ⅴ. Never use the lift to raise the vehicle whose weight is above 4 ton. 2. Introduction on Main Parts of the Lift The two post double cylinder hydraulic lift is the more convenient lift for maintaining the vehicle. The following words will help you understand the working principle of the device before using please read this instruction manual carefully, so it will help you operate and use maintain this device in correct way and prolong its lifespan. Equipped with arm lock and the synchronic device of the carriage, the lift is characterized with its simple and reasonable structure, low noise, and steady rising and lowing. After installation, connect the power to the power unit, the gear begin to work and the hydraulic oil enter the oil cylinder and push the piton rod up, which cause the chain lift carriage and arm. Since the minimum lifting height of the equipment is quite low, this device can be used widely. Because it’s convenient to operate, it’s used as the necessary maintenance equipment. It’s not allowed to lift vehicle whose rated weight is above 4 ton with this equipment. This model of lift is equipped with CE‐stop, when the arm drop to a certain level, the stop would sing to inform the operator that the lift would lift or drop to the ground, so the lift would be used safely and avoid any damage to operator. Attention: This model can be used in the ground which is not so strong.

Step 7: add hydraulic oil

Put in N46＃ hydraulic oil about 10L. Step 8: Power On

Install power control box, ensure the power connection by motor nameplate, which requires installation of main switch beside the lift to make convenience to cut down the power in case of emergency. Please connect by corresponding numbers when installing the power control box.

The electric system should operated by electrician!

Step9: plus grease to the cavity guide of the two column

Step10: Debugging 1. Check insurance system installations, to see if increased, whether the

insurance is in the lock state (at this time, normally, the insurance is locked, that is, four electromagnetic iron absorption in a disconnected state); against falling, must first press the lock button, and then the drop button, there will appear a slight rise before the process of decline, at this moment the insurance is undocked from the state, check whether the four electromagnetic absorption iron are working; and to see whether the four blocks of the insurance are disengaged at the same time. (Relating to the insurance working principle, please see below description)

2. Check the tensioning force of two same‐step wire ropes, to complete the synchronization of two carriages by adjusting the two same‐step wire ropes.

Step11: Overload test Check the hydraulic system to see whether it is working properly

and lift availability of anomalies. Make sure everything is ok to install the block cloth and the column top. 5. Checking Points before Using

. Operate the up and down movement several times before ⅰplacing the vehicles on, to ensure the safety lock is in the correct place and the equipment is normal. Check all joints, especially the safety mechanism, to ensure no abnormal phenomena before using, if the insurance device doesn’t work, the lift should not be put into use. . Before using the lift, adjust the height of the four rubber pads to ⅱmake all supporting points in the same flat level, and separate the arms as open as possible so that it’s easy for the vehicle to drive in, and it’s better to use the short bracket arms to support the motor end. . The center of lifting area should be the gravity center of the vehicle ⅲthat needs maintaining. When the car is raised to 100 mm high, stop and swing the car a little to check whether lifting support is reasonable, and whether the lift is working normally, if everything is normal, go on to use the lift. . When lift is rising, operator and other people shouldⅳ stand in the

safety area. When the vehicle is raised to the required height, press the locking button to lock the lift, then the maintainer can start his work to repair the vehicle.

When the vehicle is raised to the required height, press the locking button to lock the lift, then the maintainer can start his work to repair the vehicle.

. Cut off the power when the ⅴmaintainer is not in the working area to avoid any accident caused by the wrong operations by non‐operators. . Remain ⅵ clearance under the bracket

arms when the lift is dropping, or the lift will be damaged. . Fill the oil tank of hydraulic cylinder ⅶ

with approximately 10 liters of N46 hydraulic oil, or diesel oil of No.8 in winter and No.11 in summer. Half a year afterwards add hydraulic oil again. . After pressing the down button the lift ⅷ

will rise a bit then drop. . Cut off the power when repairing the ⅸ

vehicle and there is no operator or nobody using the lift.

9. Information on Structure and Working Principle of Equipment 9.1 Main structure of equipment Lifting system: Hydraulic cylinders are installed inside columns, when hydraulic oil enters the lower part of the cylinder, piston lever move upward and push up sliding collars to move upward. Supporting system: the vehicle enters the working area, by adjusting the angle and extension length of arms to make the rubber tray support the vehicle in its effective supporting points. Adjust the height of the tray according to the height of the car bench. Balance system: when raising or dropping the vehicle, two pieces of chains connects two sliding collars and make them move together to keep the lift’s balance. Security system: there are electrical security device in the main and supplementary column which will lock automatically after the vehicle is raised up.
