Whats the proper technique for breaking in a chainsaw?
I agree 100%Don't baby it in the cut, give it full beans but don't do long extended cuts without a break, tune it a little rich, don't leave it idling. Run it hard from new to seat the ring but don't full throttle for long out of wood
That's what I've worked out from my experiences and the advice of people whos opinions I respect
Thanks Brad . Makes good senseIf the wood is big enough to load the saw, never use anything other than WOT. If knocking off little limbs and such, that's different. No need to have the saw screaming without load.
You didn't hurt anything though.
I've researched this a bit. Most of what I have read states to run it hard but not for to long. A heavy load at lower rpms is going to give you your highest cylinder pressure. The high pressure slips past the piston crown and gets behind the rings and pushes them firmly against the cylinder. It's the rings that need the attention in break in. All engines gain compression after the rough spots on the rings are smoothed out perfectly to the cylinder walls.
(1) Don't do wot without a load.
(2) Run it wot with heavy load for 20-30 seconds then let it cool down for a while.
(3) Repeat #2 till the first tank is out. Just my.02
yu mus be gud at mathI'm and engineer, we **** **** up to see if we can break it and how it will break, then we try to design it so we can't break it again.
When you buy a new saw they extend the warranty if you buy stihl synthetic oil. If that's the case I would say there is nothing wrong with using it from the very start.Would conventional oil be better to use to break in a new saw than synthetic?
I think the thought there was that conventional oil is not quite as slick as synthetic. For breaking in maybe conventional oil is better for allowing a little more friction to aid in breaking in the piston rings. I'm guessing the difference is slim and it wouldn't really matter for break in.When you buy a new saw they extend the warranty if you buy stihl synthetic oil.
