FS-KM Line Head Trimmer is rated 3.4 out of 5 by 49.
Rated 5 out of 5 by from String trimmer issues I’ve had my 131 for about a year now and love it, I have 3 attachments and plans for at least a 4th. I started with the string trimmer and like all stihl products I own it works very well. That being said operator error, and cheap string can cause headaches. If you wind your string too tight or put too much on a spool you will have problems. But if you have a little common sense, properly mixed fuel and quality consumable materials to go with your quality equipment there is no reason you can enjoy years of hassle free use.

Rated 2 out of 5 by from The string continually binds in the spool and breaks The string continuously binds in the spool requiring a disassembly of the head to rethread. We have tried several different wnd techniques to no avail. We are using Stihl line.

Rated 1 out of 5 by from Cutting line very difficult to advance The cutting line is very difficult, bordering on impossible, to advance on this head trimmer that goes with the Kombi System. I try to advance the line as the instructions state, by tapping the head on the ground while the engine is at full power and it takes multiple time for the line to advance, no matter how much line is already out there. I have only had this unit about a month, and so far I have had to take the head off and pull the line out manually on numerous occasions. . NOT GOOD. I am going to put new line in and see if that helps, but so far, I am very unhappy with the performance of this trimmer.

Rated 5 out of 5 by from Enjoying it So I upgraded from an FS 40c to a KM 91 unit. I of course got the FS KM head. I broke off one side of the string like several people have stated. I had no problems re working the spool to keep the job going. I will admit it was user error with me. Not the trimmer head. Haven’t had a single problem since. I like this attachment a lot.

Rated 1 out of 5 by from Awful trimmer Since we got a bigger yard, I wanted to upgrade from battery-powered serviceable edger to something more powerful and convenient, and based on what I read and heard, this system was the answer. Pleasantly surprised by the power of the KM 111 and was excited to start edging. However, I should've paid more attention to the reviews. I immediately had issues... within the first three minutes of operation I realized it was a bad decision to purchase this. I spent more time stopping and popping the string housing open to feed the lines through. Once I realized I couldn't run it very long before the string wore out all the way to the end, I had to stop OFTEN and see how much length I had, then bump it for added length because it was just chewing through my trimmer string - not in minutes, but in seconds. What should've taken no time to complete ended up taking a lot of time. Very frustrating.

Rated 1 out of 5 by from *** DO NOT BUY THIS ATTACHMENT *** I own 4 attachments for the Kombi KM 131R system. I love the system over all however I am sorry to say I hate and regret buying the FS-KM Line Head Trimmer. Like many of the other reviews I too spend more time re-feeding the line than I actually do edging. I have tried all the recommendations set forth in the reviews to no avail. Please save yourself the headache and do not buy this head trimmer. I also own the tree hedger, extension pole and the rotatable chain saw and love them. Just don't buy this product until STIHL offers an improved version. I wish I could return it and get my money back.

Rated 2 out of 5 by from Motor runs great, but feeder head needs work. I own a lawn service and wanted a quality tool, so naturally I purchased a Stihl. I purchased the KM 131 power head, the bed edger, the string trimmer, and the BR700. I expected a quality feeder head like the other components. Within one minute of beginning to use the trimmer for the first time, the line broke at the out feed location. I spent more time taking the head apart multiple times at my first customer, than using the trimmer. Not only is it hard to take apart and restring, it's a pain to do. What I don't understand is why they didn't put a speed loader on a commercial unit knowing time is money to us commercial mowers. I've read the review saying to soak the line. I've never had to soak line for any string trimmer I've purchased. Never had this issue with any other string trimmer.
