Ensuring your car won’t move when using a scissor jack is crucial for safety. Start by parking on a flat, stable surface, engage the parking brake, and use wheel chocks. These steps prevent the car from rolling, providing a stable base for lifting.
What Are the Steps to Safely Use a Scissor Jack?
Using a scissor jack properly involves several key steps to ensure both your safety and the stability of your vehicle. Here’s a step-by-step guide:
-
Find a Level Surface: Always park your car on a flat, level surface to prevent it from rolling.
-
Engage the Parking Brake: Before lifting the car, ensure the parking brake is fully engaged. This adds an extra layer of security.
-
Use Wheel Chocks: Place wheel chocks behind the tires opposite the side you’re lifting. For example, if lifting the front, chock the rear wheels.
-
Locate the Jacking Point: Refer to your vehicle’s manual to find the correct jacking points. Incorrect placement can damage your car or cause instability.
-
Position the Scissor Jack: Align the jack under the jacking point and ensure it’s perpendicular to the ground.
-
Lift the Vehicle: Turn the scissor jack handle clockwise to lift the car. Stop once the tire is off the ground.
-
Secure the Vehicle: If working under the car, always use jack stands for added safety.
Why is a Flat Surface Important?
Parking on a flat surface is essential because it minimizes the risk of the car rolling. A slight incline can lead to instability, making it dangerous to lift the vehicle. Additionally, a stable surface ensures the scissor jack maintains its grip and doesn’t tip over.
How Do Wheel Chocks Enhance Safety?
Wheel chocks are essential for preventing movement. Made from durable materials like rubber or metal, they are placed behind the tires to stop any rolling. This precaution is especially important if you’re lifting one side of the car, as it helps maintain balance.
Types of Wheel Chocks
| Material | Durability | Cost | Best Use Case |
|---|---|---|---|
| Rubber | High | $$ | General use |
| Metal | Very High | $$$ | Heavy vehicles |
| Plastic | Medium | $ | Light vehicles |
What Are Common Mistakes to Avoid?
Avoid these mistakes to ensure a safe lifting process:
- Ignoring the Parking Brake: Always engage it to prevent movement.
- Using Improper Jacking Points: This can damage your car and lead to instability.
- Skipping Wheel Chocks: Essential for preventing rolling and ensuring safety.
