Really Dumb Grease Gun Question

[Mass. Wine Guy]

I just bought a Stihl grease gun for my saw, like this one:

I loaded it with grease. How do I use it? I'm betting that opening the back and pushing down the inside of the cylinder is the wrong way.

Ideally your just put the tip of the gun into the grease fitting the push it in. The spring load will push it back out...last couple I got gave me problems so I I pulled the end cap off stuck a piece of wood in the end and pushed on the wood...then the grease came out OK. $2 doesn't get you much anymore.

Sounds like the check valve is stuck open. I've seen them air lock and take a while to get primed.

general consensus is either grease always or never.
Once you start greasing the sprocket tip, you need to keep greasing it. The grease forms a dam that prevents bar oil from reaching the rollers, so you need the fresh oil contained in the grease.

I rationalize, not want to push dirt from the gun (which was usually in a dirty toolbox) or in the hole in the bar, into the rollers. In reality, I just don't want to grease it. So I never use them, just rely on bar oil. I think that is what most do nowadays. Oil is much better compared to the 'good old days'. If I ran waste oil, I'd grease the tip though.

But it should be just push on the back end and it should pump. Will need to purge the air in front of the grease though, may take a bit of pumping.

Hmm. I probably screwed up the gun. There was a little round plastic thing inside that was attached to a circular thing. Oh well, what's $9?

That is the piston that pushes the grease with atmospheric air pressure when the pump inside forms a vacuum. The ring is to pull it out for refilling.

I bought one before I realized my bar didn't have a grease hole. LOL
I called my dealer and asked why no hole. He said more sprokets are screwed up by pushing dirty grease in there than by not greasing
so some bars no longer come with them.

Did you fully extend the gun before you put grease in it? It should extend to 3 sections. Then just push slightly to get grease flowing. I use the same type of gun to oil the chuck on my lathes and grinders at work, except we use 90 weight type oil.

Naw its OK leave the plastic ring be and put a screw driver handle against it and push in on it ...why throw away $9. Ya it's crude...but effective.

crude...but effective.

That's how folks describe me.

I've never greased the tip on any bar on any of my Stihl's

I just squirt oil from an oil can into the hole, on each side.
