So I picked up this 266se last fall from a nieghbor that was moving. I got it running today and need to cut down a 30"+ diameter tree tomarrow night. My other two saws are smaller 20" and 18" saws, but this one has a 30" bar on it. It's been a few years, 15, since I used my fathers big old husky while clearing land outside boston for our house. The neighbor gave me a bunch of misc. stuff with the saw, including a grease gun with a needle tip on it. Given the fact that he gave it to me with the saw I figure I need to use it somewhere on the saw. Where do you add grease to this thing? Gas, bar oil.. I got all that, just need to know where to put the grease.
