Jacks and Jack stands are essential items that car mechanics and car owners should possess. They are essential because accidents can be avoided and repair work and maintenance work can be successfully completed on the car.
- Before starting work on the car, one should check if the car is placed on an even surface and not on an uneven or inclined surface.
- The jack is used only to lift the vehicle from the ground. To hold the vehicle and to work underneath it, jack stands have to be used.
- The jack should be used only after placing blocks such as wooden wedges or bricks near the wheels, to prevent them from rolling. The parking brake should also be set, to provide complete protection. If the rear wheel is lifted, chocks should be used, as the parking wheels are usually found on the rear wheels.
- Avoid highways while changing tires for safety reasons.
- Only jack stands should be used to hold the car up. Stones, bricks or boxes should not be used. The car should firmly rest on the stand before proceeding further with the repair work.
- Standard jacks like scissor jacks can be used only for emergencies. For regular job works, only floor jacks such as hydraulic trolley jacks should be used.
- While raising the car, it should be correctly positioned on the car. This is a necessity to prevent harm to the car. The owner’s manual can be referred to, to know the correct details.
- The scissors jack or the hydraulic jack can be used, to lift the vehicle. If the scissors jack is used, the rod should be inserted over the knob and then cranked. If a hydraulic jack is what you use, the handle should be placed in the appropriate location and then pumped upwards and downwards to lift up the vehicle.
- The stand should then be placed under the vehicle, where the jack touches it. It should be raised till it reaches the right height, by which it fits under it and should be locked up safely. The jack should now be lowered to allow the vehicle to rest on it.
- After ensuring that the car is fixed securely, it can then be removed. Once the repair work is completed, the jack can then be fixed again. It can now be removed and the car can be lowered. If you use a scissor jack, the crank should be turned in the opposite direction. If you use a hydraulic jack, the pressure release valve should be pressed.
Cars can be easily lifted off the ground. It is a simple procedure, that every mechanic should know and all car owners should learn to do to face emergencies and for safety reasons.
