Problems cutting with the Stihl 1/4 pitch chain

[Steve Bullman]

I have bother the ms150 and also the battery topping saw running the Stihl 1/4 pitch chain. Aside from how finicky this tiny chain is to sharpen its basically a fantastic pruning chain leaving almost a silky finish.

 

However I keep getting a recurring problem when cutting. The saw seems to act as it would had the chain been sharpened one sided, the saw feels like its veering off and gets to a stage where the saw doesn't want to move any further. I'm pretty competent with my sharpening so didn't put the issue down to this, plus the fact it happens even on a relatively new chain which has had very few sharpens.

 

I was working with a new climber yesterday who was also running a 150, so I mentioned my issue with the chain and he has experienced the same, and thought it was just him. So i'm not the only one, yet not heard any other complaints here or elsewhere.

 

My own theory, if using the saw at a funny angle, the slight twist in your wrists is potentially enough to veer the fine chain off course giving this feeling that its not cutting straight. Keen to hear if anyone else has experienced this same thing and has any opinions on it

Hi steve,i use a 150 a lot infact i prefer it to the 201,i have to say ive never had this problem either with sharpening the chain or it veering off in the cut.

Is your 150 modded?

The reason i ask is perhaps the added power means the chain cant cut quick enough to keep up with revolutions of the engine giving an uneven cut.

Just a thought..

Id be interested to hear what silky says about his 150,i know he uses it often.

Is the bar bent

I use my 160 a lot.It does require that the bar is introduced at 90 degrees to the grain Any deviation to that and it can run off track but i'm ok with that.Almost thrives on a fetherlite touch.

Mine was fine with a brand new chain but a couple sharpens later was cutting on a curve, just the tiniest of difference in the tooth length on one side seems to make it do this as after another, more careful sharpen its cutting straight again. I just think the chain has to be spot on

Cheers for the replies.

 

No burred bar

Try sharpening with a Stihl 2 in 1 easy file, results seem to be very good

Side of depth gauges protruding beyond the side plate of the teeth blocking the cutting face? chain tension as well allowing twist if too loose ? Or wear in the bar guide rails allowing the chain to twist off angle to the guide rails as had this issue with a 660 a few weeks ago

Always found this to be an easy chain to sharpen so can't see this being the issue. I reckon it's a problem with the bar. Can be hard to spot sometimes.
