Bleeding a floor jack is a process that is used to remove any trapped air in the jack’s hydraulic system. Air can become trapped in the system due to a variety of reasons, such as when the jack is not used for an extended period of time, or when the jack is not operated correctly.
To bleed a floor jack, you will need a few tools, including a wrench, a container to catch any fluid that may be expelled during the process, and a way to refill the jack with oil.
Begin by positioning the jack on a level surface and extending the jack fully. This will help to ensure that any air that is trapped in the system will be released more easily.
Use the wrench to loosen the bleed valve, which is typically located at the base of the jack.
Place the container underneath the valve to catch any fluid that may be expelled during the process.
Slowly press the jack handle down to release any air that may be trapped in the system. As the air is released, you should see fluid flowing out of the bleed valve.
Once all the air has been released, the fluid should flow out smoothly and without any bubbles. If bubbles are still present, repeat step 4.
Tighten the bleed valve using the wrench.
Refill the jack with oil to the recommended level. This will vary depending on the make and model of your jack, so consult the manufacturer’s instructions for the correct amount.
Test the jack by raising and lowering it a few times to ensure that it is working properly.
It’s important to note that bleeding a floor jack should be done periodically to ensure the jack is working at peak performance. Also, always use the proper fluid and consult the manufacturer’s instructions for specific guidance.
