[product introduction]
 This jack works on hydraulic principle. Because of its compact structure, small size, light weight, carrying, and has been widely used in mobile lifting operations, if used in cars, tractors and other vehicles as a tool is particularly suitable.

[specific operation]
lifting
    1. Turn the jack oil valve clockwise with the handle (turn to the most tight place).
    2. Place the jack below the correct jacking position of the vehicle. If necessary, rotate the adjusting screw on the jack counterclockwise until it touches the vehicle.
    3. Insert the jack handle into the handle sleeve and operate the handle up and down until the vehicle reaches the desired height.
falling
   (caution: slowly lower the vehicle and slowly rotate the oil return valve)
    1. Remove the handle and loosen the oil return valve with the handle (please slowly turn the handle counterclockwise and loosen the oil return valve). Note: do not loosen the oil return valve for more than 2 turns.
    2. After the vehicle is completely lowered, move the jack (if the adjusting screw is in the state of lifting, rotate it clockwise until it completely disengages from the vehicle)

[scope of application]
Erect the jack is only suitable for use, can not be offset or to use, operating temperature is to 40 ° c ~ 45 ° c, forbidden to acid and alkali and corrosive gas.

[matters needing attention]
1, before use to estimate the weight of the heavy, do not overload.
2, the use of the center of gravity must be determined to lift the weight, the choice of the lifting point of the jack, placed smoothly, but also need to consider the soft and hard degree of the ground, when necessary, should be padded with a tough board, to prevent the lifting of skew or even dumping.
After jacking up the heavy objects, the jacks should be supported firmly with the tough wood of the support frame. Jacks are not allowed to be used as supports.
4. If several jacks are used at the same time, the lifting speed should be kept in sync, and the load of each jack should be balanced, otherwise there will be a risk of tilt.
