Rated 1 out of 5 by from won't start I own several STIHL products, and this one is just not one I would recommend to anyone. I've owned it 5 years now and been in the shop 7 times all because it won't start or once it starts it won't continue to run. I don't have time to continually take it into the shop on top of the money it's cost me to get it fixed all the time. If there was a trade in offer I'd be there in a second to get rid of it.

Rated 5 out of 5 by from typical Stihl Quality This is my forth Stihl product and it rates as high as all the others. After reading some of the reviews about being difficult to start, I was a little hesitant, but I have had zero problems. Going from an electric trimmer to gas was a game changer as the power and no cord to drag around made a dreaded chore one that is much easier.

Rated 5 out of 5 by from Another great Stihl product This is my fourth Stihl power tool purchase and it performs flawlessly. You can't go wrong with Stihl. Spend the money, you won't be sorry.

Rated 5 out of 5 by from I Would Buy It Again After reading several of the reviews on here I decided to put my two cents worth in on this particular product. Being a journeyman mechanic I fully understand the complaints leveled against this trimmer. Allow me to add what I have learned in the past couple of years. With out any doubt in my mind the biggest issue with the starting and carburetor problems comes from Ethanol blended fuels. Ethanol likes moisture and moisture likes ethanol. After all it is made from water to begin with. It will literally pull moisture out of the atmosphere and form little water puddles in the bottom of the fuel tank. I have seen a lot of the carburetor problems come directly from the use of these blended fuels. I had issues with all of my outdoor care products because of this. From my lawn mowers to my chain saws they all were having carb issues that resulted in hard to start and performance issues. After figuring out what the biggest issue was, I have since switched to non ethanol gas and my problems went away. I do agree that this particular trimmer is a little hard to start until I finally followed the instructions to the letter for initial start up. After the first cold start up though, I didn't have any more issues with starting. I realize in some states you can't buy non ethanol fuels. That is unfortunate. However there are premixed fuels available at the dealers for these tools that doesn't have ethanol in it. The problem with it is it is usually expensive. Personally I think it is worth it if you can avoid the cost of repairs . I like Still products. They can be a little bit heavy but if you want quality then it is usually going to be heavier than consumer grade products. You get what you pay for in other words. I would buy this trimmer again if I needed to. I would and have recommended it to friends and family.

Rated 1 out of 5 by from Stopped working Had various 2 cycle products. This trimmer has had the shortest life of all. Would not recommend it. Hard to start and finally it has stopped starting. Replaced carb, plug, filters but nothing seems to help.

Rated 5 out of 5 by from Light but powerful I have owned this product 10+ years and it has been a steady performer. Use it very often on shrub, it cuts thin and thick with ease. Never any running or cranking problems. I have replaced the blades 3 times but over 10 years is not bad the use one gets out of the blades. Have owned cheaper models and the gear box always tears up, this one never a problem.

Rated 1 out of 5 by from Always the same carburetor issues I´m from Brazil and bought this machine there almost 2 years ago and has been 10 times on the dealer. It´s getting carburetor blocked. It had 3 three carburetors in less than two years. I`m sick about it and spent much money to get it fixed so far. I´m not supposing selling cause my unity rarely works. I´ll buy an electric brazilian model instead even if I have to work with force cable. At least it will work.

Rated 1 out of 5 by from Good trimer bad at starting Bought at rural king this month followed the instuctrctions exact and very difficult to start. I bought Stihl because of their reputation but I have had much less expenceive gas trimer that start with no problem. There was a problem starting at the store and the salesman told me because it was the first time started. Not at all happy with this product. Wish I could get my money back.
