Common types of car jacks include scissor jacks, hydraulic jacks and screw jacks.

When choosing a car jack, you must first consider the required lifting capacity and stability. Factors such as vehicle type, height requirements, portability and safety should also be considered.

Before using the car jack, be sure to read and understand the relevant instructions and safety precautions to ensure correct operation. Make sure to use it on a solid and stable ground, avoid overloading, and check the working condition of the jack regularly.

Clean the surface and moving parts of the jack regularly to ensure sufficient lubricant and normal operation. Repair or replace worn and damaged parts promptly to avoid using damaged jacks.
