How to Open a Car Jack?

Method to open a car jack: Find a flat ground surface, then place the jack on the ground. Near the wheel edges on both sides of the vehicle chassis, there are support points designed for the jack to contact. Align the jack with these chassis support points and turn the handle to lift the vehicle. Each jack has its own load capacity range, which is indicated on the jack's label. Before using the jack, make sure to understand its load capacity and working limits. It's important to perform the lifting operation steadily and slowly during use. Do not use the jack on incompatible vehicle bodies to prevent insufficient lifting force and potential accidents.
I always thought operating a car jack is pretty straightforward, the key is to familiarize yourself with the process. First, park on level ground, engage the handbrake, and ensure the car is stable. Then retrieve the jack from the trunk – most vehicle tool kits include one. Align it with the designated lifting point under the car, usually a notch near the wheel. Turn the handle or knob clockwise by hand, and the jack will gradually rise. Don’t turn too quickly to avoid shaking the car; lift until the tire is about 1 cm off the ground. After use, turn counterclockwise to lower it, wipe it clean, and return it to its place. It’s best to practice occasionally to avoid panic during a tire change. Also, avoid using the jack on a slope – rolling wheels can be dangerous. Some older cars use scissor jacks, which require more effort to crank, while newer models might have lighter options. Safety first – never stand under the car while operating the jack.
After years of driving and frequent tire changes, I've learned that jack safety is paramount. First, ensure the car is parked on solid ground with the handbrake engaged, and place bricks or wheel chocks in front and behind the tires. Position the jack under the vehicle's designated lifting points, usually marked on the frame. Turn the small handle counterclockwise slowly and steadily—no rushing. If the jack creaks, it might need lubrication or could be rusty. After changing the tire and lowering the car, inspect the jack for rust and apply oil if necessary to prevent seizing. Store it in a dry toolbox to avoid moisture and dust. Remember, lifting too high risks tipping, so control the height. Make it a habit to check the jack during routine maintenance to avoid issues when needed.
