Home Automotive Tools Why Do Grease Guns Stop Working?
5/51 rating

Grease guns are air-operated devices that push grease to the point where it is needed. There are a few reasons why grease guns might stop working.

The internal mechanism of a grease gun consists of an “air chamber,” which converts the compressed air into potential energy and then, when released, acts on a piston, pushing out the grease. If there’s no pressure in the chamber (i.e., the air hose is disconnected), the piston cannot move, and the gun will not work.

One more reason might be that the barrel is clogged with old grease or dirt. Another potential issue could be that the seal between the barrel and the pump has worn out, preventing grease from being pumped through the gun. Finally, the spring inside the grease gun might have broken, preventing the piston from moving and forcing grease out of the nozzle.

How do you fix a grease gun?

If your grease gun isn’t working, the first step is to check the air pressure. Ensure that the air hose is securely connected to the gun and compressor and air pressure is coming through the hose. If there is no air pressure, you might need to replace either or both of these components.

The next step is to check the grease nozzle itself and make sure it is clean and clear of any debris. If the nozzle isn’t clear, try using a toothpick or similar item to free up the nozzle. If that does not clear the nozzle, you might need to replace the nozzle itself.

If neither of the steps works, there’s possible a problem with the piston inside of the grease gun. Taking apart and cleaning your grease gun should solve this issue if this is the case. After doing so, you’ll need to make sure that the gun is reassembled correctly. If that does not fix the problem, you might need to replace the piston itself.

In any case, if your grease gun isn’t working correctly, it’s best to take it to a professional to get it fixed. It will ensure that the gun is properly cleaned and serviced and addressed any potential issues. In addition, by taking care of your grease gun, you’ll be able to return it to its former glory and use it for many years.

How to prevent a grease gun from breaking?

A grease gun is notorious for breaking. There are a few ways to prevent this from happening, though.

First, make sure that the gun is properly lubricated. It will help keep the moving parts well-oiled and working smoothly.

Second, always use the correct type of grease for your gun. Using the wrong type of grease can cause the gun to overheat and break.

Third, make sure that the barrel is clean and free of obstructions before each use. Finally, be careful when using a gun. Try not to force it to do anything it’s not supposed to do. It can also lead to breakage.

By following these tips, you can help keep your grease gun from breaking and ensure that it lasts for years to come.
