Something wierd happened yesterday???

[Bad E]

THe chain on my Husky 365 Special came off during a wedge cut while felling a 18-20 " maple tree? I just tightened the chain very snugly before cutting. Had dropped a couple of other tress and cut them into 30' chunks when WHAM off comes the chain in the downward cut on the front wedge cut.

When I went to put the chain back on one of the driver teeth would not fit down into the groove on the bar. I filed off burr on that one driver and all went well after. Where did I go wrong? Been cutting for over 20 years and never had this happen before.

Saw that happen to a buddy of mine this last summer, he was dropping a 50" doug fir with my 066, and while fully buried into the slant cut on the face, the chain threw. Never seen it before or since. Can't come up with a good explanation aside from that the chain sometimes chatters a bit on the slant cut on some trees.

sometimes if your putting too much pressure on the saw, at the angle it is in the cut it could throw the chain

Ran Husky saws for a long time 200 and 300 series, had my chain come off only when I was limbing or cutting small small stuff. Never had my chain come off when I was putting in an undercut or backcut, puzzled.
