Whether you’re dealing with a flat tire or need to get under your vehicle for essential maintenance, knowing How To Work A Car Jack safely is a crucial skill for every car owner. This guide provides a detailed overview of different types of car jacks, step-by-step instructions on how to use them correctly, and vital safety precautions to ensure a smooth and secure lifting process.
Understanding Car Jack Types
Before you start, it’s important to understand the two main types of car jacks commonly used: floor jacks and scissor jacks. Each has its own advantages and is suited for different situations.
Floor Jacks

Floor jacks, also known as trolley jacks, are popular for their stability and ability to handle heavier loads. Equipped with wheels for easy maneuverability and a long handle for hydraulic pumping, they offer a smooth lifting action. These jacks are ideal for home garage use, especially for tasks like routine maintenance or when used in conjunction with jack stands. Always verify that the floor jack’s weight capacity is appropriate for your vehicle’s weight.
Scissor Jacks

Scissor jacks are recognized for their compact and lightweight design, making them perfect for roadside emergencies and storage in your car’s trunk. Often supplied with spare tires by car manufacturers, they utilize a simple screw mechanism for lifting. While universal scissor jacks are available, some are designed for specific car makes and models, requiring placement on designated lifting points. Your car’s owner’s manual will specify these crucial locations.
Choosing between a floor jack and a scissor jack depends on your needs. For regular car maintenance like oil changes or brake work, a floor jack is recommended. However, for emergency wheel changes, a portable scissor jack is a convenient and cost-effective option.
Step-by-Step Guide: How to Use a Car Jack Safely
Operating a car jack is straightforward when you follow the correct procedures. Below are instructions for using both floor and scissor jacks, along with how to use jack stands for added safety.
Preparation for Both Jack Types:
Before using any car jack, ensure your vehicle is parked on a level, hard surface. Engage the parking brake firmly and put the car in first gear (or “Park” for automatic transmissions) to prevent any rolling. Wheel chocks can be used for extra security, though they are not always essential.
Using a Floor Jack:
- Locate Safe Lift Points: Identify your vehicle’s designated lift points. These are reinforced areas on the chassis, typically located near the front and rear wheel arches. Your owner’s manual is the best resource for pinpointing these exact locations.
- Position the Jack: Carefully maneuver the floor jack so that the jack’s saddle is directly under the identified lift point. Ensure the base plate is securely positioned beneath the car’s sill.
- Begin Lifting: Slowly pump the jack handle to raise the vehicle. As the saddle approaches the lift point, proceed cautiously to ensure proper alignment and even weight distribution.
- Raise to Desired Height: Continue pumping until the tire is lifted off the ground sufficiently for your task. Many floor jacks feature a locking mechanism to secure the jack arm, enhancing safety when working under the vehicle.
- Lowering the Vehicle: To lower the car, carefully move the jack handle to its vertical position and gently twist it. This action releases the hydraulic pressure, allowing the vehicle to descend slowly and smoothly.
Using a Scissor Jack:
- Identify Specific Lift Points: Scissor jacks must be used precisely on the car’s safe lift points. Consult your owner’s manual to locate these, as scissor jacks often require specific placement within grooves on the vehicle’s undercarriage.
- Assemble and Position the Jack: Scissor jacks usually come in two parts: the jack itself and a separate handle. Attach the handle to the jack and position the jack under the designated lift point.
- Raise the Vehicle: Insert the handle and turn it in the direction indicated for “raise” (often marked ‘R’). Lift slowly, especially as the jack contacts the car, to ensure correct alignment.
- Secure the Area: Once the car is raised, remove the handle to prevent tripping hazards or accidental knocks.
- Lowering the Vehicle: To lower the car, turn the handle in the opposite direction, usually marked ‘L’ for “lower,” until the vehicle is safely back on the ground.
Using Jack Stands for Enhanced Safety
Jack stands are vital safety equipment when working under a car for extended periods or for tasks requiring extra stability. They are also beneficial for long-term car storage to prevent tire warping.
Steps for Using Jack Stands:
- Lift the Front of the Car: Locate the front safe lift points and use your chosen car jack (floor or scissor jack) to lift the front of the vehicle, following the steps outlined previously.
- Position Jack Stands: Once the front wheels are off the ground, place jack stands at the safe lift points on both sides of the car.
- Lower onto Jack Stands: Carefully lower the jack so that the weight of the vehicle is transferred onto the jack stands. Ensure the car is stable on the stands before proceeding.
- Repeat for the Rear: Repeat steps 1-3 for the rear of the vehicle, placing jack stands under the rear safe lift points so that all four wheels are elevated and the car is fully supported by the jack stands.
- Lowering from Jack Stands: To lower the vehicle, use the jack to slightly lift one end of the car, just enough to remove the jack stands. Repeat on the other side, and then gently lower the car back to the ground.

Using a car jack involves inherent risks, so prioritizing safety is paramount. Always take your time, use appropriate equipment, and correctly identify your car’s safe lifting points. Here are crucial safety guidelines:
- Engage Parking Brake and Gear: Always ensure the car is in first gear (or Park) with the parking brake firmly applied to minimize the risk of rolling.
- Consult Owner’s Manual: If you are unsure about safe lift point locations, always consult your vehicle’s owner’s manual. Never attempt to jack up your car if you are uncertain about the correct lifting points.
- Use Correct Equipment: Verify that both the car jack and jack stands are rated for your vehicle’s weight. Using equipment with insufficient capacity is extremely dangerous.
- Stable Surface Required: Only use a car jack on a flat, level, and hard surface. Avoid uneven or soft ground, which can cause the jack to become unstable.
- Jack Stands for Under-Vehicle Work: Crucially, always use jack stands if you need to work underneath the vehicle. A car jack is designed for lifting only and is not intended to hold a car securely for extended periods or while you are under it.
By understanding how to work a car jack properly and adhering to these safety measures, you can confidently and safely perform essential car maintenance tasks. Always prioritize safety and ensure you are fully informed before undertaking any vehicle lifting procedure.
