572 updates

[Mastermind]

I read through that thread, didn't ask you directly thinking things weren't shown to keep them proprietary.

Thanks for searching again.

Excited to see what everyone starts coming up with now that the saws are in more hands.

I intended to do a detailed thread on the 572, and the 462......but lost all the picture I had for both of them.

Then......I decided that doing threads was a pain in the ass.

That is AWESOME!!!! Now you get to drive 200 miles to buy a saw.

No, she has to go in thurs. I'll just ride with her.

Shoot that's only 3 hours at most.

 

[Mastermind]

I just have saws shipped to me. What's all this talk about driving to get one?

 

[shadco]

Ok this is better went from 20” Husky to 24” Tusmura and gained a tenth of a pound.
The bar is lighter the chain is obviously heavier.

With the full skip from redbull it’s 18.3

It’s funny the stuff we talk about. The saw is soo good that all we have to currently *b-word about is a wiggly lever.

FYI: my saw is an EU model and 8months old. The lever also wiggles side to side, a little more play then the 562 (2017); but even the 562 has side to side play. It is of no concern. I’ll take some photos, now I’m curious if they may have changed molds between last year and now.

If we really want to nerd into this then we have to start comparing plastic mold dates on the tanks.


Anyone have some muffler mod pics they would like to share?

my levers are just fine fyi

Wife chastised me fer driving 100 miles rd. trip & not buying a saw, so I called today & had one put away for me.
First 572 sold by Minneapolis saw. Probably pick it up Thurs.

Cheryl's a keeper, Jon. Tell her I say hi.

Dang you guys are gonna have me buying one of these yet

It’ll be faster with the full comp

I really wonder if there is a break in period programmed into the firmware.

Husqvarna rep left the 572 last week. We’ll have it for 3-4 weeks. Got a chance to run it yesterday. As with any AT or M-Tronic I made three 20” cuts with a steady FIRM load to maximize the fuel settings. After I came out of the last cut, I pinned the throttle. It should have bounced off the rev limiter but didn’t. Also during the second and third cut I didn’t feel that little rush of heat on my left hand as it leans out looking for max RPM and settles back into an acceptable heat to RPM fuel setting. Saw has approximately 5 tanks through it. I didn’t hook it up to the Service Tool, shop manager was hogging the computer. Do I think it has a built in break in period, YES. During the test cuts it felt like it was holding back a little sumptin’. Don’t get me wrong....the saw ran great.

That being said, my “testing” ain’t that scientific. I’ll run it again next week after some more run time on it. Its been issued to one of the crews. They love it. The saw performed flawlessly but I only ran about a half a tank through it. And yes the top cover is a tight fit especially around the primer bulb. Had no issue with the operator presence lever

Might not be scientific but your test sure sounds like it’s based in experience. Good write up.

 

[ferris]

For the shelf or for work?
Will u sell some saws for that?

 

[dustinwilt68]

I already parted with 5 Stihls in the last 2 days, so I should be good if I want one, but it would just sit more on the shelf unfortunately, really holding out for 550 xpg mark II.

 

[danimal]

Bout as scientific of a break in, as it can get in my books.
Fuel it, fire it, run the dog snot out of it.
It'll run or lunch. That's science rite there..

 

[Simondo]

Maybe there is , maybe there is not , some sort of cleaver system working during a brake in with the 572 . If there is then Husqvarna would be missing a good "PR opportunity" IMO.....if they didn't make at least some mention of it to perspective customers one way or another. Would help show how there trying to build in thoughtful design and a eye on longevity with the 572

Do it Randy!

I for one feel your build threads are very education, informative and at the very least entertaining!

I know it is a pain for you but I will publicly state I enjoy them!!

 

[old guy]

Standart stihl bar?
Or the light version?
With only the powerheads, i can feel the difference

Standard bar.

I have one of those waiting here for the saw too.

This was very common in the 2 stroke power sport and marine industry. Much of it unpublished but acknowledged by the engineers if you got them away from the office.

We think of break in period in tanks run through the saw cause they are easiest to count. Husky measures it by run time in hours, which they list as 3-4. This goes way back to the 200 series saws for which they always recommended running them at break in RPM's, typically 600-700 less during the break in period. They suggested this for both new saws and rebuilt saws. Some food for thought there for guys who do builds/projects on these older saws and then go right to the max RPM's on the first tank.

So, the theory that AT is doing this is likely correct. The AT module does keep tract of run time in hours, minutes and seconds. Also, I lent out a 565 demo to a logger to run 10 thanks through it, and the total run time when he brought it back was around 4 hours. Kind of all adds up, doesn't it?
