AirCat grinder - lubrication needed?

[Squankum]

This is my AirCat grinder. I like it. Not that I know anything about air tools; I'm new to compressed air.

Very few instructions came with it. The usual sermon about putting lubricating oil into the air intake end before and after use. That was basically it.

Where the pointy tool is pointing, is this some kind of lube port?

Just put a drop or two down that holy thing you couple the airline to. You get to much in the holy thing it will start blowing oil all over your work piece. Be aware of that, just messy and will dry out with a few trigger pulls.

Yes. That is where you grease the gears (a straight die grinder would be purely lubricated by the oil in the air, an angle has greased gears).

One of those tiny grease guns with a cone tip is meant to fit that.
There's the style I posted an image of, or a similar one that a small tube of grease screws into, or the inline style that looks like a screwdriver (popular for chainsaw bar sprockets).

Don't go overdoing it with grease.

Thanks, rlitman! Now... how much grease? Until the bad grease oozes out of somewhere else? Heh heh, somehow I suspect that's not SOP in this application.

Two squrts of grease every couple of months and a yearly re-build where you clean out the gear housing and replace the grease is what Aircat recommends. I use Super Lube Synthetic grease on my air tools with the grease fittings. Of course, a couple drops of air tool oil every day goes into the air coupler as well. Marvel Air Tool Oil is my favorite for this application.

take a look at your tool's owner manual as far as how much to lube

One thing to watch for - I ordered this IR lube kit and the grease gun only had one tip which did not fit my Aircat. I got one of the Cornwell's mini guns that came with 3 tips and one of those worked.

I'm pretty sure the Mac and Snap On are the same as the Cornwell and come with multiple tips. I just found a deal so I bought the CW.
