How to retract a jack?
4 Answers
The method to retract a jack is: You need to unscrew the hydraulic valve to release the hydraulic pressure before retracting it. Turn the vent valve at the bottom counterclockwise. A loaded jack will descend automatically, while an unloaded one can be retracted by adding some weight on top or pressing down the lifting column. Self-lowering screw jacks have non-self-locking threads and are equipped with a brake. Releasing the brake allows the jack to descend quickly on its own. A jack refers to a compact lifting device that uses a rigid lifting component as the working mechanism to elevate heavy objects within a small stroke via a top saddle or bottom claw. Jacks are primarily used in factories, mines, transportation sectors, and other industries for vehicle repairs, lifting, and support tasks. They feature a lightweight yet sturdy structure, are flexible and reliable, and can be carried and operated by a single person.
I've been driving for over twenty years and have dealt with retracting a jack many times. First and foremost, safety is paramount—make sure the car is securely parked on level ground and not wobbling in the air. The retraction method depends on the type of jack: for a mechanical screw-type jack, grab the handle and slowly turn it counterclockwise, and it will lower automatically; for a hydraulic jack, locate the small release valve, usually shaped like a wrench or knob, open it to let the oil flow back, and the jack will gradually descend. Take your time during the entire process, moving gently to avoid sudden loss of control and potential injury. Regular maintenance is also important—I clean the jack's threads or add lubricant every six months to prevent jamming and rust. After changing a tire, remember to fully retract the jack and store it properly in the toolbox to extend its lifespan and save on repair costs.
When I first bought a car, I was completely clueless about the jack, but retracting it is actually quite simple. The key is to operate after the vehicle is securely parked: for mechanical ones, turn the screw handle counterclockwise to lower it; for hydraulic ones, just open the release valve. I once tried moving a bit too fast and almost dropped it on my foot, so I recommend taking it slow and steady. Learning this can save a lot of trouble—once I forgot to retract it and drove off, damaging the jack screw. Now I make it a habit to check the flexibility of all parts after each use, especially ensuring the hydraulic valve isn’t blocked, keeping it clean and stored in a cool place to make the tool last longer.
DIY car repairs at home save both hassle and money, and using a scissor jack is a common practice. To stabilize the car, simply turn the jack in the opposite direction or open the valve to lower it. Keep your hands steady during operation to prevent slipping, and teach children at home that safety comes first. For maintenance, wipe off dust regularly to avoid rust and jamming. Store it neatly to save space—practical and economical.
