At this time, pull out the hand crank, use the head of the crank to rotate the pressure relief valve counterclockwise for one and a half turns, slowly press the piston rod to the bottom, then rotate the pressure relief valve clockwise for one and a half turns, insert the hand crank, press the hand, and shake it up and down. The jack can work (Please press the piston rod and shake the hand crank slowly when using it for the first time. If the speed is too fast, the hydraulic oil and air in the cylinder will produce bubbles. After the hydraulic oil level is raised, a small amount of hydraulic oil will be discharged from the exhaust hole. This is a normal phenomenon. After multiple cycles of work, this phenomenon will be eliminated.) Note for use: Vertical jacks can only be placed vertically for use, not horizontally or inverted. When the jack shakes the hand crank, the piston rod cannot hit the top. Use a syringe to add hydraulic oil to the oil filling port. Please place the jack at the highest lifting position. If the piston rod is in the recovery state, the jack cannot be placed horizontally or inverted. Otherwise, the hydraulic oil will flow out from the oil filling and exhaust holes. If you need an instruction video and a video on filling hydraulic oil after receiving the product, please contact customer service for help.
