JDM-163 1/10 hydraulic jack model hand-cranked vertical jack model

JDM has launched an all-metal jack model with a stainless steel cylinder, aluminum alloy base shell, simulated appearance, precise structure, two-stage piston rod, and a conservative lifting force of 15 kg.

Instructions for use: When the player receives the product, the jack is at the highest point of lifting. At this time, pull out the hand crank, use the head of the joystick 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 down 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.)

Use precautions: The vertical jack 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. When placing the jack, please place it at the highest lifting point. 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 exhaust hole.
