Rated 4 out of 5 by from Instructions Why will Stihl not let you print instructions and manuals. Would like stringing printing instructions for the first 38.

Rated 1 out of 5 by from Never worked Bottom Line: impossible to start, constantly out of adjustment so stalls frequently and string head rarely feeds properly. I have been a long time Stihl customer and I always discount reviews that are this negative. Regardless, I have to be honest. This is a terrible product. It's the New model of the one I purchased 16 years ago (FS35 now FS38) but this one is a plastic toy compared to it.

Rated 1 out of 5 by from Not a Sthil level product I could not believe this product has the Sthil name on it. It is underpowered, hard to use and not fit for general purpose trimming. It stalled in relatively short grass time after time. After a few minutes of use you need to stop and add new cutting wire. the dual design of the spool allows very little cutting wire to be loaded each time. % minutes later you get to do it all over again. I have 2 Sthil chain saws and a "big boy" grass blower. They are all fine products and do a great job. If you're going to but a Sthil trimmer, buy a larger one. You'll be disappointed with the FS 38.

Rated 4 out of 5 by from Great power for an entry level trimmer, would buy it again. Nice trimmer for my average size yard. Lots of power for a small engine. Pay attention to the starting procedure and follow it exactly or it will flood. Also make sure to turn the switch on every time, it's a true on and off switch. It is old school 2 cycle, so it is harder to start but rewards you with simplicity and durability of older designs.
