@#$%^^&*%!! Grease Gun!!!

[PTRich]

I own 4 grease guns ranging in price from $10 to $100 dollars. Here is the problem. After I use a gun once the gun will not push any grease, the handles just move freely with little or no resistance. The only gun I can get to work is the small one I paid $10 for. The larger ones seem to only be good for keeping the dust off the floor under them. I am sure I am doing something wrong. I put the open grease container (yes both sides) in my gun with the plunger pulled back. After closing the gun I push the plunger all the way in and lock it in place. Please help me! /forums/images/graemlins/crazy.gif /forums/images/graemlins/blush.gif /forums/images/graemlins/confused.gif

Not quite sure I understand what you mean here. You lock the plunger back to install the grease tube. Then you screw the plunger portion back on the gun. At this point you should just release the locked plunger and the spring should take care of the rest. You then say you are locking the plunger again somehow which would then stop the spring from doing its job which is keeping forward pressure on the grease in the tube so the gun doesn't lose its prime. Did I just misunderstand? /forums/images/graemlins/confused.gif

It sounds like you have air pockets in your grease guns. There should be a fitting on the head of the grease gun that you can crack open. Pump until grease squeezes out around the threads and you feel a pressure buildup on the lever, and then tighten back up. If you hand pack your grease guns they will be prone to have air pockets. I just cleaned two of my grease guns for grease type change over and noticed that there were areas in the head where the grease hardened through the years. It is not fun cleaning grease guns, but plenty of paper towels help.

Hard to say for sure, but sounds like air in it; not an unusual situation. Instead of just pushing the plunger rod in and locking it, try pushing it in and out a few times to work the air out of it. Some (but not all) grease guns also have a valve at the top to let air out. The only other possibility I can think of off hand is if you put the tube of grease in backwards (how many will admit to having done that? /forums/images/graemlins/grin.gif) The end of the tube with the metal end goes toward the top or outlet end of the gun.

Looks like you typed faster than me, Rob. /forums/images/graemlins/wink.gif

I must still have some grease left on my fingers from cleaning those guns.

This has happen to me a few times.If you can not blead the air out on top of the gun try loosening the part the grease tube goes in that screws on the trigger.It has worked for me.

I have 3 grease guns. The only one I haven't had problems with is the pneumatic one. Like was stated the problem is air pockets.

Here is what I learned to cut down on problems. When you fill your gun squish some grease from the tube. You want to fill the head of the gun with grease. Yep that means getting your fingers greasy. I use latex gloves. Make sure there is no air gap at the end of the grease tube as well. Now screw them together.

So I should release the rod and leave it hanging out?

Loosen the top of your grease gun a couple turns. Pull back on the rod and turn it until it locks onto the plunger. Now push it in until grease starts coming out from around the threads of the loosened top. Tighten the top back down and release the rod and push back in. Should be working now. /forums/images/graemlins/smile.gif
