Troubleshooting Guide: What to Do When Your Hydraulic Floor Jack Won’t Go Up

A hydraulic floor jack is a great tool to have in your garage or workshop. However, when it won’t go up, it can be a source of frustration. There are several possible causes of a hydraulic floor jack that won’t go up. Let’s take a look at some of the most common ones.

Check the Pressure

One of the first things to check when your hydraulic floor jack won’t go up is the pressure. If the pressure is too low, the jack won’t be able to lift the load. To check the pressure, you will need to consult the manual that came with the jack, as different models have different specifications. If the pressure is too low, you may need to add more hydraulic fluid.

Check the Hydraulic Hose

The next thing to check is the hydraulic hose. This is the tube that connects the jack to the hydraulic pump. If the hose is damaged or has a leak, it won’t be able to transfer the pressure from the pump to the jack. To check for a leak, look for any signs of fluid around the hose. If the hose is damaged, you will need to replace it.

Check the Release Valve

The release valve is responsible for controlling the pressure in the hydraulic system. If the valve is not working properly, the jack won’t be able to lift the load. To check the release valve, you will need to consult the manual that came with the jack. If the valve is damaged or stuck, you will need to replace it.

Check the Cylinder

The cylinder is the part of the jack that lifts the load. If the cylinder is damaged or has a leak, the jack won’t be able to lift the load. To check for a leak, look for any signs of fluid around the cylinder. If the cylinder is damaged, you will need to replace it.

Other Possible Causes

In addition to the above causes, there are a few other possible causes of a hydraulic floor jack that won’t go up. These include:

  • Faulty Pump: If the pump is not working properly, it won’t be able to transfer the pressure from the reservoir to the jack.
  • Clogged Filter: If the filter is clogged, it won’t be able to filter out dirt and debris from the hydraulic fluid.
  • Air in the System: If there is air in the system, it won’t be able to build up enough pressure to lift the load.

Conclusion

A hydraulic floor jack that won’t go up can be a source of frustration. However, with some basic troubleshooting, you can usually figure out the cause of the problem and get your jack working again. Always remember to consult the manual that came with your jack before attempting any repairs or maintenance.
