Stihl FS 90 line problems

I have a FS90 and I am having problems with it. I got it as a gift for Christmas and began using it a month or so ago. The problem I am having is the line keeps breaking at the head. So I took it back to the dealer and he suggested the new auto cut head. So I bought it, installed it and yet the same problem. The line seems to break flush at the eyelets, I guess that is what you would call them. I have to stop and pull it back out of the holes. I am using stihl line. What gives, two different heads and the same problem. I actually stopped using it and went back to my trusty old Echo SRM-210. I have used the 210 for 5+ years and this has never happened once. Also to add, I really do not like this trimmer, really prefer the Echo over it. Looks like it may go up forsale.

Any help here would be great. Thanks.

Im just wondering if its the line. Bad batch maybe

What Stihl line are you using?

I use the Oregon Magnum Gator .105 line in a FS 55 with no issues. I think I would try a different brand in a small quanity to see if you like it, and it fixes the issue.

The trimmer came spooled with line and that did the same thing. I then bought a reel of .95 orange stihl line and the same thing. I guess I will go out and give the gator a shot.

Was thinking about a FS90 for a second trimmer. Also looking at a Husky 326 LS. The Husky may win out.

Only drawback is my Stihl dealer is great.

Stihl FS 90 line problems

How short are you letting the line get? I notice if you are trimming and the line gets to short it will cut it at the eyelets...I tend to always tap the head to keep it all the way out

Take the spool and soak it in water for a night and don't let it get too short

Is this happening with round line? Are you trimming with really high RPMs all the time?

Eagle,
I use 3 FS90's---3 KM 90's and two KM 110's.....each with the same head.
.95 size line.....quad or star line. The circular line sometimes.
The reason the line keeps snapping is the line is twisting inside the spool and pinching or you are keeping the head to low to the ground as you are probably straight edging. The line will become heated from slapping concrete or asphalt and will snap at the ends, but snapping at the eyelets is improper height use.
My line is on the trailer on a spool caddy.......so it gets wet from natural causes.....or becomes brittle from oxidation and temperature's.
You Can soak it in water if you desire, but after 28 years of using line trimmers, it is about experience of knowing how high and low you are trimming.

Switch to a heavier line, that orange crap that comes with the trimmers and new heads isnt worth much at all. It breaks constantly, use stihl X line weight .105.
