Quick Lift Auto Maintenance Jack 3ton for Auto Repair Lifting

The normal working temperature of jack oil pump is 10~50 ℃. If the oil temperature is too high, cooling measures shall be taken or the pump shall be stopped; If the oil temperature is too low, heating measures or low pressure operation shall be taken to increase the oil temperature. Before starting the motor, change the reversing valve to the middle half position. Jog several times to prevent the high-pressure pump from being emptied, and use it only after air is removed.

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.
