Thread: How do you prime a grease gun?

  1. #1

    Default How do you prime a grease gun?

    Everytime, I change my tube, I run into this problem.
    Is there an easy way to prime a grease gun?
    I've pumped and pumped, with the handle open, with it closed, only with it open on the down pump.
    I've tried almost everything, but no grease.
    Usually, I give up and a day later or so after pumping and pumping, I get it.

    This can't be the right way, can it?

    I remove the tube/hose from the head of the grease gun to pump the grease past the check valve. Then reinstall it. Works for me…

    Get a better grease gun. I had that trouble with my Harbor Frieght special, but my Car Quest grease gun pumps right up every time.

    Thanks for the heads up... I've always fought with my pos.

    there is usually a bleed screw at the top of the grease gun. loosen the screw to release any trapped air. once grease starts to ooze out of the bleeder hole, tighten the screw back down. you should be good to go at that point.

    good luck.

    Typically, you first insert the magazine, release the safety, and pull the bolt back to load the first round into the chamber.

    (And before someone tells me that's all backwards and I'm liable to shoot my own foot off, the safety on a grease gun locks the bolt so it can't move.)

    Both of mine (flex hose and hardline) have a spring-loaded bleeder valve on the top, so it's just a matter of making sure that it's depressed when you first load the cartridge. From time to time I'll get an air pocket in a grease tube, and will have to re-seat the main tube pressure plate (again, with the bleeder valve depressed to release the trapped air).

    If you store the guns upside down it'll help keep them from forming air pockets....especially when the main spring begins to 'get tired'.

    Thanks, That did it.
    I heard a puff of air come out that was trapped by the screw.
    After that, the grease started to flow.
    Thanks again.
