New Saw Problem

Do you have another chain you could try on it?

 

Well campinspecter at least your still cutting straight.

Last year I sharpened mine, and it scalloped the cuts.
Like a big huge U on the cut. Needless to say, I took that chain off and put on a fresh one.

 

Weird that the cuts are straight, just on an angle. May need to adjust the sights

 

OK, this is likely a stupid thought, I've had more than "2" over the years.

Could it be that the weight difference between this saw and your old saw is such that it is cutting downward at an angle, and you aren't compensating for the weight difference??

The cuts are straight, but angled. Given a new saw with different weight, and possibly not the same "balance" of the other saw, could be for lack of compensation on the part of the new saw.

I'm a novice when it comes to sharpening and cutting, so it's not something I've experienced before.

 

Very possible.

 

Bought a new chain and bar for the 570 two weeks ago. Both the 570 and 390 are doing the same thing. I think it's a batch of bad chain.

 

I would pull the b/c and see if the is a slight bend in the bar. Just because it's new does not mean it is strait. Could have got a tweek somewhere. Also check to see if it is mounting true to the case. If not the bar I would say chain.

 

touch up the chain and see how it does

That is a "stumper" Allan!
Do you normally run a skip tooth chain? I'm really "swinging wide" (wag)* with this one, but with a skip tooth with half the teeth, a bastard length bar you might have an extra left cutter that would be a bigger issue over a regular tooth chain.

*wag = wild aaz guess, I learned that here at WHC!

 

The Dealer went right to work on the bar and chain. He put on a new wide gauge bar and told me to run the saw wide out and dig the dogs in and make it cut. It works much better now. The dealer did this at no cost to me.
The log that I bucked was a yellow cedar - three foot in diameter. I cannot believe the speed in which the new 390 went through the log compared to the old 570.

 

Huh? What does that mean?

 

It means operator error in that I was not wanting to push the new saw too hard as per instructions in the manual. I let the weight of the saw take the bar through the cut. The weight of the saw being heavier on the side opposite the bar slightly made the bar side higher making the cut go to the right.
I think going to the dealer and eating some humble pie is in order!

 

I owned 076 Stihl and ran a forty two inch bar on it and just let the weight of the saw supply the force to make the cut. No issue of the cut running sideways.

 

I think it means the rails are thicker, making the groove narrower.

 

I’ve also seen that before - the cutters were sharp but the angle was a little bit different from side to side.

But if he changed to a different bar that could well have been the problem too. Glad you got it sorted out! Touch up the chain if it still feels wrong to you.

 

You were right on!

 

Its really feels good to have things sorted out!

 

Now things are sorted out, I have to go back to the dealer and straighten things out as I now have a extra bar and chain which cost me nothing. The new bar and chain, although it's a thirty six inch bar and chain, is a inch and quarter shorter than the original bar. When I bought the saw, I got four chains with it. The dealer has a deal - if you buy three chains, you get the fourth one free, so now four chains have to be shortened to fit the new bar. What would be a fair way to to straighten things with the Dealer, money wise?

 

If he sold you a mismatched bar and chains in the first place, I’d hope you could just return the wrong ones and he’d make it right. Especially if you just spend a grand or two in there the other day.

He gets his lightly used bar and bad batch of chains back, and you get 3 new chains that are the right ones for your new bar. Seems only fair to me.
