So you run the saw WOT in a piece of big wood how long? Do you calibrate then vary the speed until the ten hours is up? Just looking for the answer as the manual only says to vary the speed for the first ten hours of use. I'll start a new thread....

What 10 hr break in? I just did an electronic search of their manual and find no such reference for the 576xp at.
I think it is 5 minutes WOT in wood. You will want to do that when you change bar lengths or say if you cut in 100 degree weather and then 30 degree weather. You may not always have to do that unless you notice performance is diminished from the weather or bar changes.
As far as break in, these things are designed to be run at WOT so run it like a ***** ape to break it in.

I'm looking at the manual right now pg. 18 under "running in". Straight from the supplied manual from Husqvarna, "Avoid running at a too high speed for extended periods during the first 10 hours." I interpret this to mean not to run at WOT to calibrate until after the (10hr.) break in period. That's will I'm posting and asking in this thread to do it properly...

I interpret that as the you should have the saw under load ( in a log ) and not out in the driveway piss revving it showing your buddies how sweet your new saw is.
Yes makes sense. With my other saws I have just put them to work, like others have suggested. I'm new to this autotune feature and just want to do it right! I never understood why people want to high rev saws excessively out of wood anyway.

Some of it boils down to how some people run saws. Cut with my uncle yesterday, and let him have a go with my Stihl ms460. I'm hard on things, but he had that saw hanging way high in the rpm range. Made me cringe a bit, and reminded me why me and my pro saws are a package deal. You want to borrow one of my good saws, I'm coming with it. Very few exceptions.
You are supposed to cut wood at WOT all the time. It makes no difference whether the saw is new or 100 hours old.
The high jet on a chainsaw carb typically is tuned somewhere between 12,000-14,500 rpm. That is the rpm achieved at WOT with no load (out of wood) and is what is meant by by "high speed."
All moderns saws typically run around 10K rpm under load (in wood). That, as you may guess, is not "high speed."

The 562 has a 5 minute break in period. Run WOT for 5 minutes, use as normal.
AT is not set up to run at half throttle. This saw is meant to run WOT all the time. You can goober it at half if you wish, but saying it's meant to have varied speed isn't accurate, and I see of no mention of that in the manual.
I just got mine 2-3 weeks ago, and I've almost cut 5 full cords of pine with it so far. It's a monster.

Thank you everyone for helping me understand the terms as stated in the manual. Today I put the saw into a big round and ran it at WOT while noodling.
550 was wearing 18" its now wearing a 16" sugi. 576 is wearing 20" soon to be wearinf 24" full time
Well I am very happy with the 576xpat purchase. Cut 3 cords last weekend of elm and cherry and yes it did its job as advertised. A couple of the trunk sections were 22inch and there was no comparison to the Ms290 except the weight which really didn't seem that bad. So far I am very happy with the purchase!

I just bought a 372xp a month ago. You can't go wrong with it. I have a 20" bar on it and it eats wood like crazy. Fantastic saw!! I could cut all day with it.
