I bought this chainsaw based on the reviews. However. I seriously wish I'd never bought it now. It is an absolute nightmare to get going .Everytime I want to use it I have to return to the store to get the staff to get it going. I deeply regret buying it and wished I'd got and electric chain saw.

Purchased in April 2018 at Braschs for $250.00.

cheap rubbish


was ok to use at the start, used this chainsaw 8 times and nothing but troubles. under powered, no decent tuning ability and now it is not running in the high rpm range. it is unable to be tuned like most decent chainsaws and i have decided to bin it as the cost of repair does not warrant the return to service. i will go buy a decent echo next or a cheap bunnings chainsaw i think.

Purchased in December 2017 for $300.00.

Worked great3 times. Took in to the dealer they said i mixed the fuel too lean. And scored the piston took the spark plug out bought a new one plugged it the coil wire gripped it my hand and got a Very little tingle!! Called Stihl got no reply back from the West coast rep.

Absolute rubbish


Have had this rubbish Stihl chainsaw for four years and it has always been difficult to start. It has been "serviced" by the dealer twice, and is no easier to start. My previous chainsaw - a Husqvarna - was great and was always very easy to start. I will be tossing this Stihl chainsaw in the garbage.

worst chain saw ive ever owned


one of the most pethatic and useless saws ive ever owned bought it 12 months ago and ive been back to the dealer 7 times due to faults on the machine, this saw is just terrible, ive previously owned husqvarna saws and they have worked wonderful for me not a problem, i only bought a stihl on the advise of a mate saying they were alot better, its heavier, its louder, it struggles even on small logs with a sharp chain, this machine is everything that is wrong in the world!
this saw needs to go back to the drawing board cause ive had that many problems with it its not funny,
i would never buy one of this saws again!

Can a person put a heavier chain on the ms170?

Yes you can! It is the same bar/chain combo on the MS211.

Your running a .043 bar and chain, u can go with a .050 bar and chain.. wouldnt recommend though because you power to bar and chain are mediocre you put on larger, it will require more power to run the loop and there for cut slower

Sure can though dealers are instructed to tell you it can’t be done.
Some say it will void the warranty but if you spend the extra on Stihl parts you can argue the case easily provided you don’t go overboard.
Contrary to a couple of comments I’ve seen it’ll improve your saw a great deal though you’ll have to be mindful of bearing down on it, it’s just a baby after all, just take a little time & get used to its new & greatly improved character, you won’t be sorry.

I keep sharpening my chain on my mini boss but it just won't go through small pieces of wood just keeps burning through on matter how sharp the chain is what am I doing wrong?

Make sure you have the correct size file for the chain and are sharpening at the proper angle. Sharpen from inside to outside of tooth using a forward motion only. I initially had the wrong size file and it wouldn't sharpen the chain at all.


Hi Rick,the problem is the rakers, those bumpy things in front of the teeth. Get a small flat file and give each one a couple strokes, file in the same direction as if sharpening. Try cutting again, there should be chips not dust. Repeat this process, until chips are achieved. The more you file, the more the chain digs in. You don't need to do this every time you sharpen your chain, only when you notice dust or the problem you have now. Good luck and may you spit chips.

Stihl makes a offset file that has a flat file and 2 round files in the tool. Ie as you sharpen the tooth the flat file also takes the rake down to proper height. If rakes are not correct, sharp cutters will not be able to penetrate wood
