Only one nut. Mine has two.

that's because it's not an auto-tune. :dance1:

Does the auto tune keep that one nut tight I've seen some really small saws with one bar nut but nothing that large.

 

[Bud Soda]

Can it do with one nut what it takes me three nuts to do?

Interesting. I didnt know they were offering the AT on the consumer saws already...Not even up on the Husky website yet.

That said, I'll still take my 562XP with its 2 bar nuts

 

[Bluegill2]

I'll stay with the XP saws, but that looks to be a good one!

Good to see Husky doin something for the independent dealer. But at some point wont all the saws have auto tune?

just bought my 455r/at it has 2 bar nuts to keep everything where it's supposed to be. hope it keeps working even if it drops a nut!lol

One nut doesn't look safe to me.

HVA 400 series vs 500 series

One nut is probably OK for the 400-series of plastic farmers saw and the torsion forces involved from the moderately sized bars used.

However, if using longer bars, go for the more rigid magnesium body of the professional saw series, such as 545, 550XPG, 555, 560XPG or 562XPG.

P.S.
I can tell, we have a 12 year old Jonsered CS2150 (equivalent of HVA 350) plastic or farmers/homeowners saw, which is still running like a perfectly new saw. It's light and powerful, only the plastic chaincatcher of the early version has been knocked off, all else is fine with it. Two nuts holding the chain cover and tightening the bar on the CS2150, but I am not overtightening the nuts and keeping the bar at the standard length of 13" it came with.

Not having verygood luck with mine chain keeps coming off.when it does it ruins the chain costing me about 1 chain per tree. Cuts good always have a sharp chain. Real dissapointed with mine. Two much higher power for1bolt.

Poulans are on a different line. Picked up a Jred 2255 one nutter at a good price with a 20" bar. Cut 4 cord of hardwood with it last year, the one nut was not an issue.

 

[Natureboy]

Minor correction, the Husqvarna small homeowner (235, 240) are on the same line as Poulan.

my mistake!! it does have only one nut holding the chain cover on, the other nut I am guessing is the one holding the two handles!! lol(at my self for being not to observant) .....

Husqvarna makes different grades, helps to study and learn the models, some not so good, some very good and some are the best on the market.

My 345 has been flogged on the farm for 12 years and hasn't missed a beat. I just arranged to get a new 455 autotune for fathers day with a bit more hp and 18" bar. I was told the autotune takes a little while to calibrate so I'll reserve judgement on engine performance until I've used it some.
I used the air purge as directed on the cold start ( 6 pumps) and flooded the engine so go easy on it. Also you do not, contrary to the instructions, seem to have to prime (purge) or use the choke for warm starts (just like the old 345). Just engage brake , push decompression button and leave red "on' button in the default down position (no choke).

Anyway it felt good that I could still clean out a flooded engine and get it started the old way when autotune couldn't !

You can't flood these saws by using the purge bulb. All that bulb does is purge any air from the system.

Ive been having starting and fouling issues with my 562. I think its the purge bulb that is causing it. I know the purge should have no effect, yet it seems to.

Fast idle position and pull it over seems to work 99% of the time. Purge only when I run out of fuel. Im thinking the choke should only be used in sub-freezing temps.

My 562xp has been flawless for almost 3 years, never flooded & no starting issues. I use purge and choke for cold starts and nothing for warm starts. I never pull it over more than twice on choke and it always cranks 2nd or 3rd pull.
