ironbender;
Good evening to you sir, I hope this finds you and your fine family doing well.
We used to cut firewood on stupid cold days back in my Saskatchewan days and I don't recall ever having any chain breaks either.
That said, one did want to use winter bar oil for sure - stripped the plastic oiler drive gear out of my Pioneer saw running too heavy a viscosity oil.
Can I use the term "running" or not?
True story, a buddy picked up my present Husky chainsaw from a pawn shop in Alberta - so no user's manual. I'd used it for a few days in summer and couldn't figure out why my left hand was always so hot using it. Eventually I looked up a manual online and found that of all things it's equipped with a bar heater.... who knew?
There is a switch for it, but it wasn't marked for function or even on/off - but it IS now!
All the best to you all this year ironbender.
