Reviews

FS 94 R is rated 4.3 out of 5 by 156.
Rated 5 out of 5 by from This product is powerful and very light weight I have a FS 81 that I bought new in 1990 it still works great but the bicycle handle is too much for my new place that doesn’t have a lot of over grown brush. I still wanted to maintain the 2 stroke engine and the FS 94 R was the only true 2 - Stroke that still still makes. I have found a new passion for weed earring. The dial to select the speed for trimming around plants is a great feature. I couldn’t be more pleased with this purchase. I have been a Stihl user since 1990. I also have the BR 400 back pack blower, Stihl hedge cutters with rotatable handle. You can’t go wrong with Stihl products. Chris E.Texas

Rated 4 out of 5 by from Dependable product I use this string trimmer as a weed-eater and the FS-131R as a brush cutter. Both are very good products, with only one exception: both have a weak clip that connects the shoulder strap to the shaft. After several hours use, the clip becomes bent and disengages from the shaft loop, necessitating duct tape or similar to keep the clip in place.

Rated 2 out of 5 by from Great when it works I’ve had 3 of these over the years and have had trouble with all 3. Overtime they develop starting problems or idle issues with lack of power. Usually occurs at any given moment.

Rated 1 out of 5 by from Trash! I was talked into buying these as my fs90 was three seasons old and not running perfect anymore. So after a year the carb had to be replaced. After a month in the Stihl dealer I get it and use it for one yard and the pull cord breaks on it. So I take it back in and one month later I’m still waiting on Stihl parts to come in. So when I took this one in for service I was gonna try a 111 and the sales person talked me into another 94 said It shouldn’t be having problems. So I bought another 94 and 8 weeks into ownership it’s hard to start takes forever to warm up to speed and seems like it’s already all it’s way out. Never again I’m currently looking into other brands. It is light which is why I tried them out. I don’t think these trimmers are cut out for daily commercial use.

Rated 2 out of 5 by from Trimmer is nice and light, I just wish it ran like its supposed to... Purchased from trusted dealer spring of 2019. Coming from older FS90R trimmers, the throttle response difference (feathering) between the two took a little getting used to. Quickly noticed and appreciated the weight difference compared to the four stroke "four mix" trimmers. I just wished it ran as good as my older stihl trimmers with 4-6 seasons on them. We've tried various choke/ priming combinations but the FS 94R never wants to start easily. When it does, it takes a solid minute for it to "warm up" which means my guys have to just stand there other wise it will quickly stall out. Furthermore, it is hard to get started again at the next house literally a street over (8 minutes after just using) Often on any given day of the week, my guys will grab the older stihl trimmer off the rack due to not being able to get the brand new fs 94R started and going. I don't know if I got a bad unit or what, but its very aggravating to have a new trimmer (not cheap btw) on the trailer that honestly doesn't get used much to do difficult starting and pour performance when it is running. If I would of known how bad of a trimmer it would turn out to be, I would of taken it back in the spring. I can not say i recommend this trimmer. Very disappointed in this particular Stihl product.
