Jacking :
1）Park the vehicle on a firm and level surface, and stop the engine.
2）Rotate the handle clockwise and lower the jack. After the lifting arm reaches the lowest position, rotate the handle clockwise and
close the oil return valve.
3）Carefully align the jack tray with the supporting point of the vehicle chassis （refer to the lifting position specified in the operation
instructions provided by the vehicle manufacturer）.
4）Press down the handle until the jack tray is in contact with the supporting point of the vehicle chassis （note: before jacking, ensure
that the jack tray and supporting point of the vehicle chassis are properly fitted in order to ensure proper verticality, or else they
must be repositioned）.
5）Continue to press the handle and lift the jack. The operation shall be smooth and slow, and the handle shall be pressed to the
furthest position every time.
6）When the vehicle is jacked properly, place the matched jack bracket in a proper position to support the vehicle （note: jack brackets
shall be purchased separately and always used in pairs）.
7）Slowly rotate the handle counterclockwise, lower down the jack until the supporting point of the chassis is located in the center of
the paired brackets, and rotate the handle clockwise to close the oil return valve.
Note:
With the safety pressure limit device, the jack will protect vehicles heavier than the pressure limit tonnage from lifting
Lowering:
1）Remove all tools and spare parts from under the vehicle.
2）The jack tray shall be aligned with the supporting point of the vehicle chassis. Rotate the handle clockwise, lift the jack and remove
the jack bracket.
3）Slowly rotate the handle counterclockwise （ensure no more than half a circle each time） and lower the vehicle to the ground.
4）Continue to rotate the handle counterclockwise until the jack reaches the lowest level.
During the use of this jack bracket, it is necessary to pay attention to the following:
1） The rated load of the jack bracket is the combined load of both brackets, and overloading is not allowed during use.
2）The supporting points of the vehicle chassis shall be located in the center of the paired brackets before use, and the brackets shall
be safely locked to prevent slipping.
3）The paired brackets shall always be maintained at the same height during use.
4）Incorrect use of jack bracket may result in personal injury and vehicle damage.
IV. Inspection, maintenance and cleaning:
1）Never use damaged jacks as this could result in severe personal injury. If there is any abnormal sound or vibration during operation,
stop operation and conduct troubleshooting and repairs.
2）All parts shall be checked before each use. Check for broken, bent, deformed, loose or missing parts, or any other conditions that
could affect normal operation. The jack can only be used after all problems are solved.
3）Functionality inspection shall be carried out before each use. If it cannot work normally, check whether venting or oil filling is
required.
4）Check the jack frequently. If the top end of the piston rod, transverse shafts, universal joints, rollers, casters or other rotating parts
lack lubrication （i.e. grease）, please add grease immediately.
5）Replace the hydraulic oil at least once every 3 years. The hydraulic oil replacement procedure is as follows:
a）Lower the jack to the lowest level and release and remove the oil filler screw.
b） Overturn the jack and drain out all the hydraulic oil （hydraulic oil shall be disposed of according to the local laws and
