How to Use a Hydraulic Jack?

Insert the grooved end of the handle into the release valve and rotate it clockwise to tighten the valve. Estimate the weight, determine the center of gravity of the object to be lifted, select the focal point, and correctly position the lifting point. Remove the handle from the handle sleeve, insert it into the release valve, and slowly turn the handle counterclockwise to loosen the release valve. Lower the jack slowly.

I often use a hydraulic jack to change tires, and experience tells me safety comes first. First, find a flat and hard surface to park, pull the handbrake and turn off the engine to ensure the vehicle is stable and immobile. The jack must be placed at the correct lifting point of the vehicle, usually under the door where there is a reinforced metal area—align it properly to avoid damaging the chassis. Then, use the handle to pump the hydraulic part up and down repeatedly, and it will gradually lift the car, relying on the hydraulic principle of internal piston operation. After lifting, don’t rush to crawl under the car for repairs, as the jack may be unstable or leak oil—immediately use stable blocks or stands to support the frame for added safety. Operate slowly; pumping too fast can cause the car to shake. Once done, open the pressure release valve to let the oil flow back slowly, allowing the car to descend smoothly—don’t let it drop freely. I also recommend regularly checking the hydraulic oil level of the jack and adding oil for maintenance to prevent aging. Take your time during the whole process—beginners should read the manual carefully or ask for assistance to avoid accidents and delays.

Last time I had a flat tire on the highway, I managed to fix it myself using a hydraulic jack. I parked on the flat roadside, shifted to P gear, and engaged the handbrake. Then I took out the tools from the trunk and aligned them with the lifting points under the car. By repeatedly pumping the handle, the pressure built up and the car slowly rose. Remember not to use full force when pumping—just a few gentle presses will do. After changing the spare tire, I turned the valve to lower the car slowly, preventing any sudden drops that could cause injury. I made sure never to stand under the car during the operation, as it would be extremely dangerous if it slipped. That experience taught me to clear small stones from the ground before placing the jack to ensure stability. After use, I wiped the tools clean and stored them properly to prolong their lifespan. I recommend practicing this routine occasionally to stay calm in emergencies. The hydraulic system is quite simple, relying on oil pressure without complex parts, making DIY repairs time-saving and cost-effective.

Operating a hydraulic jack is quite straightforward. Park on level ground and engage the handbrake, then position the jack at the designated lifting point. Pump the hydraulic handle evenly to raise the vehicle gradually. Be patient and avoid sudden forceful pumps—keep the motion smooth. Once raised to the desired height, proceed with repairs, but remember to avoid staying under the vehicle for safety. Before lowering, slowly open the release valve to depressurize and let the car descend steadily. Regularly check the hydraulic oil level and clean the exterior to prevent debris buildup.
