When it comes to vehicle ownership, having a solid grasp of how to use car jack is a must-have skill. Whether you find yourself stranded with a flat tire on a remote road or need to perform routine maintenance, the ability to effectively use a car jack is a must-know for all car owners. This article will explore the step-by-step process of how to use car jack correctly, ensuring your safety and equipping you with the knowledge to tackle various car maintenance tasks.
Purpose of a car jack
A car jack is a mechanical tool used in vehicle emergencies and for routine upkeep. The primary objective of a car jack is to temporarily elevate a vehicle, creating access to its undercarriage. This access is necessary for tasks such as changing tires, inspecting components and conducting minor repairs.
Parts of a car jack
- Pump handle: The pump handle is used to raise and lower the car jack. It provides leverage to operate the hydraulic mechanism or lift the vehicle through a mechanical action.
- Saddle or cradle: This part of the car jack supports the vehicle’s lifting point, distributing the weight evenly to prevent damage.
- Hydraulic cylinder: In hydraulic car jacks, the hydraulic cylinder contains the hydraulic fluid that creates pressure, allowing the jack to lift the vehicle. Pumping the handle builds pressure in the cylinder, raising the vehicle.
- Release valve: The release valve controls the lowering of the car jack. Turning the valve counterclockwise slowly releases the pressure in the hydraulic system, gently lowering the vehicle.
- Base plate: The base plate provides stability to the car jack. It ensures that the jack remains steady while lifting the vehicle and helps distribute the load across the ground surface.
