Factory Well Quality Auto Maintenance Jack 3ton for Auto Repair Lifting

During operation, the liquid level of the oil tank shall always be kept at the centerline of the oil pointer to prevent the oil pump from being emptied. When refueling, use 120 mesh oil filter screen to filter impurities in the new oil. When in regular use, clean the oil filter every two months, clean the oil tank every six months, and replace with new oil.

The common hydraulic jack uses this principle to achieve force transmission. The screw jack pulls the handle in a reciprocating manner. Pulling the pawl pushes the ratchet clearance to rotate. The small bevel gear drives the large bevel gear to rotate the lifting screw, so that the lifting sleeve can be lifted or lowered to achieve the function of lifting tension, but it is not as simple as the hydraulic jack.
