How to Use a Car Hand Crank Jack?
2 Answers
Before use, park the vehicle on a flat and solid ground to prevent instability between the jack and the ground during operation, which could cause the vehicle to detach from the jack. For automatic transmission vehicles, simply engage the parking brake and shift to 'P' gear. For manual transmission vehicles, besides pulling the handbrake, always remember to shift into first gear or reverse gear. This point is also crucial: every vehicle has designated support points, typically located near the wheels along the edges of the vehicle's chassis on both sides. Each jack has its own lifting limit, usually indicated on the jack's label. Read carefully before use.
The hand-operated car jack is quite practical. I've used it several times, and it's been my go-to tool for every tire change. Before using it, make sure the car is parked on level ground with the handbrake engaged to prevent slipping and potential injury. Then locate the support points under the car, usually the metal beams, avoiding oil pipes or weak spots. Position the jack correctly and steadily, then slowly turn the hand crank while observing the car lifting. Stop once the wheel is off the ground—don't crank further, as going too high can make it unstable. After changing the tire or completing repairs, turn the crank in the opposite direction to lower the car smoothly, avoiding sudden drops. A key safety tip: never crawl under the car while it's on the jack, as it's only a temporary support. If you need to work underneath, use jack stands for reinforcement. Keep the jack in the trunk for emergencies, and prevent rust by storing it properly. Regularly check if the handle operates smoothly. Mastering this skill saves a lot of trouble, especially during long trips when a flat tire occurs—you can handle it yourself without waiting for a tow truck. Remember to wear gloves during operation, as the handle can sometimes be uncomfortable on the hands.
