How to Lower a Hydraulic Jack?

Connect the provided wrench and socket to the rear of the jack, then rotate it directly to lower the jack's height. When operating the jack, avoid applying excessive force, as this may cause the piston to suddenly drop, leading to potential accidents and safety hazards.
Here's how I do the oil-release hydraulic jack thing: First, make sure it's safe—no people or objects under the car, and the jack is stably supported. Locate the release valve, usually a round knob or screw near the handle. Gently turn it counterclockwise to slowly release the hydraulic pressure, causing the jack to descend. Never twist it all the way open at once—that could cause a sudden drop, risking damage or injury. I always turn it a little, pause, and check the height adjustment. If the valve gets stuck, don’t force it—spray some lubricant and try again. After lowering, quickly inspect the jack for leaks or damage, wipe it clean, and store it properly. Regular maintenance is key—topping up hydraulic oil extends its lifespan. Handling these details well makes it much smoother next time.
The most crucial aspect of safely operating a hydraulic jack is lowering it properly. Every time, I first look around to confirm the surroundings are safe before starting. The release valve is the core component controlling the descent – turn it counterclockwise slowly to feel the pressure gradually releasing. Moving too quickly could cause the load to drop suddenly, which is extremely dangerous. Continuously monitor the jack's movement during operation and stop to inspect if anything seems abnormal. If the valve feels stiff, don't force it; just apply some machine oil for lubrication. For maintenance, I recommend checking hydraulic oil levels and valve seals quarterly while keeping the equipment clean. Proper usage prevents accidents, so developing good habits is vital for protecting both yourself and your tools.
Lowering a hydraulic jack is quite straightforward—just locate the release valve and slowly turn it open. It's usually near the handle; simply rotate it to lower the jack. Once, I turned it too quickly in a hurry and nearly had an accident, so now I’ve learned to operate it patiently. First, stabilize the object, then turn the valve in small increments to lower it gradually. During operation, make sure no one stands nearby. After lowering, clean off any dust or grease. For routine maintenance, spray some lubricant to keep the valve smooth.
