  2. Next is to unscrew the air bleeder valve that is situated at the top of the grease gun head. Do 3 to 5 turns until when you hear a popping noise. Start pumping again.
  3. The follower rod should now be pulled out. Try to spin it using the T-Pull while pulling it straight down. You will feel it when it drops slightly and lock into the follower plate. Once it is locked, you can then push up on the T-Pull to force grease toward the grease gun head.

Frequently Asked Questions:

Q: How Do I Clean a Grease Gun Properly?

Answer: There are steps and processes to follow to properly clean a grease gun. To start with, you have to remove the old grease cartridge from the grease gun. Get a clean cloth to remove all the debris, dust and residue from both the internal and external part of the nozzle. Use the appropriate solution to wash the external and internal parts of the tool. Rinse them in hot water so the debris and residue can be removed completely from the grease gun. Dry it properly before loading the grease gun again.

Q: What Is the Proper Way to Store a Grease Gun?

Answer: Store the cartridge tubes of grease in an upstanding position. But if the cartridge tube is left inside the grease gun, ensure that it is well cleaned by depressurizing it. If there are contaminants in the grease gun, ensure they are removed using a clean cloth. Place it in a flat position and the area must be cool and dry to avoid draining the oil.

Q: What Lubricant Is Best for My Grease Gun?

Answer: Choose a high-quality lubricant for your grease gun. This ensures that you have a free flow of grease when using the gun. There will be no build-up issues within the nozzle area if a high-quality lubricant is used. There will also be no leakage because the lubricant has sealing properties that eliminate the risk of corrosion.
