Rated 5 out of 5 by from Great trimmer! I have had mine for over a year and it fires right up every time with ease. I used mine to trim about an acre of fence line with fairly aggressive weeds and grass. It worked great for that size job, and I really like that it isn’t heavy. I recommend this trimmer to any homeowner with a medium sized yard.

Rated 4 out of 5 by from DeAnna Dellinger Auto string not working to good. Having to stop & manually pull out longer. it could be I may have tightened the bolt to tight? I'm not sure....But The string that was recommended by salesman is too fat & very hard to refill spool.

Rated 3 out of 5 by from First review from a new owner It is an easy starter, I like the power. However I am having trouble getting used to it trimming the cemetery. I have to contort my hands and body to get into places my other 20 year old would do. Still getting used to it I guess. Being a new owner, I can't vouch for reliability and such.

Rated 5 out of 5 by from #1 Easy to start, Light weight. Very easy to maneuver, Good balance' I have had 5 different trimmers over the last 25 years, most did a fair to good job when brand new, I did not realize what a difference a quality piece of equipment can change your attitude in doing the job. I have to rate this trimmer EXCELLENT.

Rated 5 out of 5 by from Better than expected Started very easily (unlike what many reviewers say. I have no idea why, they must be doing something wrong). More than enough power. Fairly quiet and very little vibration. Very pleased.

Rated 5 out of 5 by from Worth it I rolled my eyes at the easy2start one, figuring the extra cost wasn’t worth it. But when I thought more about it, the only trouble I had in the past was starting the dang things. So I got the easy to start and surprise, it is so easy to start. One pull every time. Also it’s nice and light so my wife now enjoys trimming when I cannot. I work hard and need something that can keep up with me, this does.

Rated 2 out of 5 by from Not my favorite STIHL product The STIHL FS40C is advertised as for occasional use - I thought that once a week in the summer was considered occasional so I purchased it. My first dissatisfaction was that the head will only take line up to .080". I find that I am constantly having to add new line as that is simply too thin for average yard work. I tried finding a replacement head that will take a thicker line - but soon found that STIHL or none of the aftermarket companies make a replacement head for this model that will tak a higher grade of wire. My second dissatisfaction is that the only head that will fit on this model is poorly made. The bump cap broke in the first year under normal use. I have always bought STIHL Power yard tools - but this is the first that I have been truly dissatisfied with.

Rated 4 out of 5 by from Easy to use and fairly powerful for what you get I work for the city I live in, and have had to trim around light poles and signs, as well as in culverts. The trimmer revs high and because of that, it is hard to stop this trimmer even when it's cutting thick grass and ditchweed (the line doesn't stand up to it though). No complaints other than a small fuel tank, but what do you expect? I run it a lot longer than homeowners would ever do so.

Rated 4 out of 5 by from Its good for beginners The complaint with this trimmer is the shaft is short for me but it was my very first trimmer that i ever bought and first stihl product and i say its good but since im getting taller edger it is overbearing for my back to edge and the shaft looks a little weak and shaky when you speed up the trimmer.

Rated 3 out of 5 by from Second Stihl This was my second Stihl trimmer, the first I used for years. The carburetor started acting up, took it to a Stihl repair shop for a new carburetor. The tech cleaned and installed a kit in old carb., not what I wanted! Repair kit lasted about a month, took it back, they didn’t stock a new carb. So I purchased a new trimmer! This one is as good as the old one except for one design flaw, IT’S NOT MADE FOR A LEFT HANDED PERSON! The hot air coming out of the vent holes on the right side will get so hot it will blister my arm after 5-10 min. of use. I have to hold it in a very uncomfortable position to use more than 10 min. Will be taking old trimmer to a shop that can install a new carburetor. It’s a better built and better designed!

Rated 5 out of 5 by from This trimmer is easy to use and works perfectly. I bought this model because of the easy start feature and am not disappointed. I am an elderly woman and I have no trouble starting it. It works great for trimming areas of my yard that can't be reached with the mower. I'm very happy with my purchase.

Rated 5 out of 5 by from Perfect for homeowners This trimmer is my first Stihl purchase, and now I’m a customer for life! This is a solid, quality product. It always starts on the first pull, is well-balanced, and just works. The pcompany’s customer service has been outstanding.

I found that your products are superior to the others who do not possess the reliability and durability that your product offers. My experience has been in the past that the other products simply don’t last versus your products who provides the desired results.

Rated 1 out of 5 by from Piece of junk Had this trimmer less than a year and the engine keeps locking up. I took it back to where I bought it and they keep saying it's the gas. We have two other tools that use the same gas mix, and they run fine. This last time it locked up, the repair shop told me I had no oil in the gas. I personally put the oil in the non-ethanol gas. They said the gas would be red or blue if there was oil in it. That is not true. I honestly believe the trimmer came from the factory defective. Also, the original factory-installed cord was in the head and it stopped releasing the cord - no bump and go. I've been using string trimmers since they came out in the early 1970's, both expensive and inexpensive, and this one is by far the worst one ever.

Rated 1 out of 5 by from First STIHL product bought last STIHL product I will every buy Used to only take 15 to 20 minutes to trim the year with this weed eater it takes an hour. The line never feeds correctly or when it does feed use up a spool before 1/2 the yard is done. Do not buy.

Rated 4 out of 5 by from Good performance. Overall, I found this a fairly reliable tool albeit with a few issues. I mainly use it for edging, rotating the handle so that it trims vertically. This puts the controls in an awkward position forcing me to operate the control lever with my thumb so that I cannot get a solid grip making it hard to control. This is my biggest complaint. I suspect that a stright shaft trimmer would have been a better choice. I intially had a problem with the bump and feed feature of the autocut head. The major problem turned out to be that the string was welding itself to the spool. I found out that there is a problem common in string trimmers of ultrasonic heating. I am not familiar with this phenomena even though I spent a number years as an engineer working with designs involving heat transfer. I wish the user manual had warned me about it. One thing that apparently aggravates this is the strung slapping on a concrete sidewalk or driveway when using it as an edger. I have been carefull that the string hits between the sidewalk and the turf. It has now been working like a charm (being sure that I am running at full throttle while bumping and that the string does not get too short). It has been easy to start and it is fairly easy to replace the string.The worse part of this tool is that it is awkward when used as an edger because it is necessary to turn the motor and control switch upside down.

Rated 5 out of 5 by from Plenty of power This trimmer has more power than I expected. The only con is that I am 6’ and the curved shaft seems a little short, not sure if the straight shaft would be better for someone my height. I haven’t had to respool any line yet, so I can’t comment on that.
Date published: 2018-07-04
Rated 1 out of 5 by from Extremely difficult to fill with line A bunch of engineers got together. They all agreed, "Let's make a great little trimmer but make it an absolute chore to refill the line. Yes. Let's make the human wrap not one, but two strings around the spool." "Great idea" one said to the other, adding, "YES. And even better, when the first line gets wound, let's make it real easy to unwind while we are filling the next one! Oh fun. fun!" And finally, "Let's make the human purchase an entire head instead of just a spare spool or two. That way, in 106 degree weather, standing along the fence line, when they run out of thread, they have to stop and fill the spool instead of just snapping in a pre-wound spool."I absolutely hate this trimmer and this is my second season with it. I am getting rid of it as soon as someone on Craigs list gets sold on the Stihl name.

Rated 1 out of 5 by from Very difficult spool wind I love everything about this trimmer except spool wind. Somehow Stihl regressed two decades to a rewind that is so difficult that you cannot do it with gloves and, even bare-handed, it is easy to lose grip on the line. The prior technology is so much better!I’m really disappointed. I hope my dealer will give me credit toward another product.
