Inspect the Lifting Capacity
First of all, you need to know that each jack has a limited lifting capacity. You cannot go beyond it and try to lift something that exceeds the device’s potential.
Check the Hydraulic Fluid Level
Be it a lower or higher fluid level, both extremes are bound to cause problems, as your lifting device won’t function properly.
Bleed the system
As silly as it sounds, when a bit of air gets trapped inside your lifting device, it loses its lifting ability. When it happens, you’ll need to bleed the system to remove any air bubbles left.
Inspect the Release Valve
Okay, so you’ve checked the oil, capacity, bled the system, and your jack still won’t hold pressure?
Final Thoughts
Now that you know what to do when your floor jack doesn’t hold pressure, no more reasons to panic. Just go step by step, and you’ll find what’s wrong.

Proper Jack Placement
The first step when learning how to use a car jack is understanding where to put a jack on a car. Most vehicles today incorporate a “unibody”, or body and subframes rather than a full-frame car. The only exception would be trucks and vans.
Use the Jack to Lift the Vehicle
As stated before, there are many different types of jacks. You will need to know the specifics of how to jack up a car with the jack you own. If you are using a scissor jack, insert the rod and crank it once you have placed the jack under your car.
Place Jack Stands in the Proper Position
In addition to knowing how to jack up a car, you need to ensure your jack stands make contact with your car near the point you placed your jack. Raise your jack stands to the point at which they can barely fit under the car, and then lock the stands in place. The final step is to lower the jack until the car is resting on the jack stands.
Make Sure Your Car Is Secure Before Removing Your Jack
The fourth step in how to use a car jack is to use your hand to wiggle your vehicle just a bit. Doing so will allow you to see if the car is secure on the jack stand or not. You will also be able to see if the wheels are properly blocked so that they will not roll.
Finishing Up
After you have finished making the necessary repairs or inspections to your vehicle, it is time to lower the car to the ground.
