A grease gun is a tool used to apply grease to moving parts of machinery. It consists of a reservoir for the grease, a plunger that pushes the grease through a hose to the point of application, and a trigger that activates the plunger. Grease guns are available in a variety of sizes and styles, depending on the application.

Grease guns are a relatively simple tool, but they can occasionally malfunction. One of the most common problems is a grease gun that won’t pump grease. There are a number of possible causes for this problem, and the troubleshooting steps will vary depending on the cause.

Causes of a Grease Gun that Won’t Pump Grease

There are a number of possible causes for a grease gun that won’t pump grease. The most common causes include:

  • Improper lubrication of the grease gun. The grease gun plunger and piston must be properly lubricated in order to function properly. If the grease gun is not lubricated, the plunger and piston will not be able to move smoothly, and the grease will not be able to be pumped out of the reservoir.
  • Clogged grease gun hose. The grease gun hose can become clogged with grease, dirt, or other debris. This can prevent the grease from flowing through the hose and to the point of application.
  • Defective grease gun pump. The grease gun pump may be defective if it is not able to generate enough pressure to push the grease through the hose. This can be caused by a damaged pump, a worn-out gasket, or a clogged orifice.
  • Low grease pressure. The grease gun may not be able to pump grease if the grease pressure is too low. This can be caused by a number of factors, including a low-quality grease, a clogged filter, or a faulty regulator.

How to Troubleshoot a Grease Gun that Won’t Pump Grease

If your grease gun is not pumping grease, you can troubleshoot the problem by following these steps:

1. Check the lubrication of the grease gun. The first step is to check the lubrication of the grease gun. Remove the grease gun cap and look for any signs of wear or damage. If the grease gun is not lubricated, apply a small amount of grease to the plunger and piston.
2. Inspect the grease gun hose for clogs. The next step is to inspect the grease gun hose for clogs. Remove the hose from the grease gun and look for any signs of obstruction. If the hose is clogged, clean it with a wire brush or a small pipe cleaner.
3. Test the grease gun pump. The third step is to test the grease gun pump. To do this, attach the hose to the grease gun and fill the reservoir with grease. Then, activate the trigger and see if the grease flows out of the hose. If the grease does not flow, the pump may be defective.
4. Check the grease pressure. The final step is to check the grease pressure. To do this, attach a pressure gauge to the grease gun and activate the trigger. The pressure should be between 50 and 100 psi. If the pressure is too low, the grease gun may not be able to pump grease.

A grease gun that won’t pump grease can be a frustrating problem, but it can usually be fixed by following the troubleshooting steps outlined in this article. If you are unable to fix the problem yourself, you can always take the grease gun to a qualified technician for repairs.

3. How to Fix a Grease Gun that Won’t Pump Grease

If your grease gun is not pumping grease, there are a few things you can check to troubleshoot the problem.

1. Lubricate the grease gun. The most common reason for a grease gun not to pump grease is that the pump is not lubricated properly. To lubricate the pump, remove the grease gun handle and squirt a few drops of grease into the pump chamber. Then, reassemble the grease gun and try pumping again.
2. Clean the grease gun hose. Another common cause of a grease gun not to pump grease is a clogged grease gun hose. To clean the hose, remove it from the grease gun and soak it in a bucket of warm, soapy water. Then, rinse the hose thoroughly and dry it with a towel.
3. Replace the grease gun pump. If the grease gun pump is damaged or worn out, it will not be able to pump grease properly. To replace the pump, remove the old pump from the grease gun and install a new one.
4. Increase the grease pressure. If the grease gun is not pumping enough pressure, it will not be able to push the grease through the hose. To increase the pressure, turn the pressure regulator on the grease gun to a higher setting.

Troubleshooting Tips

If you have tried the above steps and your grease gun is still not pumping grease, there may be a more serious problem with the gun. In this case, it is best to take the grease gun to a qualified repair shop for diagnosis and repair.

4. Tips for Preventing Grease Gun Problems

To prevent grease gun problems, it is important to follow these tips:

  • Regularly lubricate the grease gun. This will help to keep the pump moving smoothly and prevent it from becoming stuck.
  • Inspect the grease gun hose for clogs. Clogs in the hose can prevent the grease from flowing smoothly. To check for clogs, remove the hose from the grease gun and inspect it for any obstructions.
  • Keep the grease gun clean. Grease and dirt can build up inside the grease gun and cause problems. To keep the gun clean, wipe it down with a clean rag after each use.
  • Use the correct type of grease. Using the wrong type of grease can damage the grease gun. Make sure to use a grease that is compatible with the grease gun.

By following these tips, you can help to prevent grease gun problems and keep your grease gun working properly.

A grease gun is a valuable tool for lubricating moving parts on machinery. However, if your grease gun is not pumping grease, it can be a frustrating experience. By following the tips in this article, you can troubleshoot and fix a grease gun that is not pumping grease.
