When jacking up a car, it’s crucial to ensure safety by properly placing wheel chocks. Wheel chocks should be positioned on the opposite side of the vehicle from where the jack is being used, specifically in front of and behind the tires that remain on the ground. This prevents the car from rolling and provides stability during the lifting process.
Why Are Wheel Chocks Important?
Wheel chocks play a vital role in vehicle safety during maintenance. They prevent accidental movement, ensuring that the car remains stationary. This is especially important on uneven surfaces or when working alone. Proper use of chocks can prevent accidents, injuries, and potential damage to the vehicle.
How to Properly Use Wheel Chocks?
-
Select the Right Chocks: Choose chocks that match the size and weight of your vehicle. Heavy-duty chocks are necessary for larger vehicles like trucks or SUVs.
-
Positioning: Place the chocks on the tires opposite the side being lifted. For example, if lifting the front, chock the rear tires.
-
Secure Placement: Ensure the chocks are snug against the tires. This involves placing one chock in front of and one behind each tire.
-
Check Stability: Before jacking, ensure the chocks are stable and the car is on a level surface.
Step-by-Step Guide to Jacking Up a Car Safely
-
Find a Safe Location: Park the car on a flat, solid surface. Avoid slopes or soft ground.
-
Engage the Parking Brake: This adds an extra layer of security, preventing the vehicle from moving.
-
Place Wheel Chocks: As mentioned, position them on the tires opposite the side you are lifting.
-
Position the Jack: Locate the jacking points on your vehicle, usually outlined in the owner’s manual.
-
Lift the Vehicle: Slowly raise the car, ensuring it remains stable. Stop if any instability is noticed.
-
Use Jack Stands: Once lifted, place jack stands under the vehicle for added safety. Never rely solely on a jack to hold the vehicle.
-
Double-Check Stability: Before working under the vehicle, ensure everything is secure.
