Hi,
Am I stupid or what?
I cant get my grease gun to pump grease, just bought a new grease gun filled it with a tube of grease and cant get it to pump grease!
Whats the trick?
Thanks

Greetings jbbcd welcome to the Forum.

They can be real tricky !!

Now, assuming you've loaded it correctly, and tightened the Barrel before you pushed the Piston back into it.

Frequently, Air gets trapped in the Head/Pump when you screw it back together.

Carefully, unscrew the Barrel about a quarter to a half turn, not enough to let it come unscrewed from the head, and sorta rotate it back and forth a few times.

If you've loaded the new Grease Tube into it correctly, you should hear Air escaping. And when it's stopped, start pumping and you should get it to prime.
Tighten it back up, and you're ready to go.

Have a good Day !

Another way to expel the air and get grease into the pumping chamber is to pull the plunger rod out and twist to lock into the follower plate, then push on the rod (by holding it against the bench) while pumping the lever. With that added pressure on the grease cartridge the pump should begin to pump grease and the trapped air should be heard coming out with the grease out of the hose.
