Rated 3 out of 5 by from NIce trimmer, issues with auto feed Like many others, I really like the trimmer. This is my first stihl product so was very excited to give it a try. It's powerful and lightweight and does a great job. But like the others I spend much of the time manually advancing the line as the bump and feed just doesn't work well. Me and several others brought trimmered our church field, and I was only one that had to continually stop and manually pull out line. Wanted to really like the product but am disappointed in this one aspect.

Rated 3 out of 5 by from Quality parts, below average operation My son-in-law bought me this trimmer for Christmas year before last. About 1/2 way through the spool (that came with the trimmer), the line began twisting itself together requiring me to open the head and manually advance the line. This happened about every 5 minutes or so. On some occasions, the line seemed to melt itself together, requiring me to pull on it hard to get it to separate. Got so frustrated, I put it back in the garage and started using my old B&D battery powered trimmer to finish; and haven't tried to use it since. In an effort to overcome this frustration, I just today bought an Stihl AutoCut C 6-2 head. I'm also going to try using a different braided line (from a different company as Stihl doesn't make their braided line in 80/1000"). Perhaps the combination will fix what (to me) is a very poor design. At this point, I'm thinking that the type of line that comes with the trimmer, is the problem.

Rated 4 out of 5 by from Powerful tool, don't like the grip & trigger. I have used it one time to cut day lilies, really tough job that hedge trimmers could not handle. Cut through a dozen plants with the same string, no problem. I need to adapt though to the trigger being so far forward on the shaft.

Rated 5 out of 5 by from Works well This trimmer replaced the stihl I bought in the early 90s. Very dependable and I believe this one will also be!

Rated 4 out of 5 by from Great trimmer, except.. I have always had battery operated trimmers in the past because it seemed all gas trimmers were difficult to start. After a demonstration of this trimmer I was sold. Very easy to start. However, I am having a problem with the "tap & go" feature, and it appears I am not the only one. Right from the get go it did not work. I had to take the head apart and manually re-thread the line. This happened every time I had to add line. When opening the head I found that the line had crisscrossed itself and I had to straighten it out. What can do to stop this from happening?

Rated 5 out of 5 by from Great home / small business trimmer Purchased the FS40 CE back in 11/13 and overall has been a great unit. I read all about the trimmer line feed issues and bad starts, but I think most of that is improper use and not following the MFG suggestions. I use ethanol free gas for all my equipment, Stihl oil and now Stihl trimmer line. I tried to increase my trimmer line size on this unit and it had issues. I went back to OEM specs and my problems went away. I still have the original trimmer head. This is NOT a commercial unit, so do not expect it to do that level of trimming. I live in Florida and we have some of the toughest and fastest growing grass in the nation. We cut yards about 45 weeks out of the year. I have 2 oversize yards, 1 standard size, and 2 small lots and this trimmer has never given me any trouble. It has trimmed 1 month's worth of growth with no issues and clean results. As for chain link fence, use the deflector as a stop so the line does not tear off. My other Stilh is a BG56 blower and it is over 10 years old. Just replaced the carb on it and it runs like new again. I have had other units and learned the hard way, you get what you paid for.
