Using a scissor jack to lift your car is a straightforward process that can be essential for changing a tire or performing basic maintenance. This guide will walk you through the steps to safely and effectively use a scissor jack, ensuring you’re prepared for any roadside situation.

What Is a Scissor Jack and How Does It Work?

A scissor jack is a mechanical device used to lift vehicles. It operates through a simple mechanism involving a screw that, when turned, expands the jack and raises the car. This type of jack is compact, making it ideal for storage in your vehicle for emergencies.

Step-by-Step Guide to Using a Scissor Jack

1. Preparing Your Vehicle

Before you begin, ensure your car is on a flat, stable surface. This prevents the car from rolling or tipping over during the lifting process.

• Engage the Parking Brake: Always set the parking brake to prevent the car from moving.
• Turn on Hazard Lights: This alerts other drivers to your presence and keeps you safe.

2. Locating the Jacking Point

Identify the jacking point on your vehicle. These are usually reinforced areas on the frame designed to handle the pressure of lifting.

• Consult Your Owner’s Manual: It will indicate the precise locations of the jacking points.
• Check Under the Car: Look for notches or reinforced areas, typically near the wheels.

3. Positioning the Scissor Jack

Place the scissor jack under the jacking point. Ensure it is aligned correctly to avoid slipping.

• Align the Jack: The saddle of the jack should fit securely under the jacking point.
• Check Stability: Ensure the jack is perpendicular to the ground.

4. Lifting the Car

With the jack in place, it’s time to lift the car.

• Insert the Crank Handle: Most scissor jacks come with a handle or a wrench for turning the screw.
• Turn the Handle Clockwise: This will expand the jack and begin lifting the car.
• Lift Until the Tire Clears the Ground: Raise the car just enough to remove the tire.

5. Lowering the Car

Once your task is complete, carefully lower the car back to the ground.

• Turn the Handle Counterclockwise: This will retract the jack and lower the car.
• Remove the Jack: Once the car is securely on the ground, remove the jack and store it safely.

Safety Tips for Using a Scissor Jack

• Never Crawl Under the Car: Do not get under the car when it is supported only by a jack.
• Use Wheel Chocks: Place chocks behind the opposite wheels to prevent rolling.
• Inspect the Jack: Regularly check your jack for wear and tear to ensure it’s in good working condition.

Common Mistakes to Avoid

• Using the Wrong Jacking Point: This can damage your car and make lifting unsafe.
• Lifting on Uneven Ground: Always find a flat surface to prevent the car from tipping.
• Overextending the Jack: Only lift the car as much as needed to avoid instability.
