Applications
The jack is a hydraulic principle of work. Because of its compact structure, small size, light weight, portable, and is widely used in lifting operations, if used in cars, tractors and other vehicles as a tool is particularly appropriate.
The jack is only suitable for vertical use, not side or reverse use, operating temperature of -40 ° c ~ 45 ° c, prohibit the use of acid and alkali and corrosive gases in places.
Some people ask what is the use of safety valve?
Safety valve is used to lock the hydraulic, to prevent overloading, in order to work in the sake of safety !!! Like a seat belt in the car, not wearing seat belts can also drive, but the accident in the seat belt With the essential role!
Specific operation:
Lifting
1. Turn the jack valve clockwise (turning to the tightest point) with the handle.
2. Position the jack under the correct lifting position of the vehicle and, if necessary, turn the adjusting screw on the jack counterclockwise until it touches the vehicle.
3. Insert the jack handle into the handle sleeve and move the handle up and down until the vehicle reaches the desired height.
decline
(CAUTION: Slowly descend the vehicle slowly to return the oil valve)
1. Unload the handle and loosen the return valve with the handle. (Please slowly turn the handle counterclockwise to loosen the return valve.) CAUTION: Do not release the return valve more than two turns.
2. When the vehicle is fully lowered, move the jack (if the adjustment screw is in the extended position, turn it clockwise until it is completely out of the vehicle).
Precautions:
1. Before use must be estimated weight lifting, avoid overloading;
2. Use to determine the weight of the center of gravity, select the jack of the focus point, place a smooth, but also need to consider the ground level of hard and soft, if necessary, should be tough planks to prevent skew or even dumping when lifting;
3. Jack will be heavy objects from the top after the timely support of the goods will be tough to support the heavy timber firmly in prison, to prohibit the use of jack as a support;
4. If several jacks are used together, the hoisting speed should be synchronized, and the load of each jack should be balanced, otherwise there will be a risk of tilt.
