I probably should have asked this question years ago, but I just thought of it.
My 15", 3.25 HP Craftsman electric chainsaw has a built-in oiler, if one pushes the rubber bulb with his thumb. But the oil chamber leaks so I've been using aerosol oil. It's made mostly for motorcycle chains, but I was told it's good for chainsaws too.
What is it I'm supposed to be oiling? The rubbing area between the bar and the chain? Or the chain's teeth where they rub on the wood being cut? Or both?
I always thought it was the first, but with that cottonwood tree hanging over my yard (and now lying in the yard) I've probably done as much cutting in two days as in the previous 10 years, so I shoulld know the right answer by now.
(Actually, I would fill the oil chamber since I'm using the saw so much right now -- even when it leaks out it only makes a little mess, but it's empty again next time I need it -- , but I can't find the non-aerosol chain oil and I keep forgetting to look again.)
