Dont buy one. 10 hours use from new and now has a scored piston and barrel. Stihl australia says there was saw dust in air filter so no warranty. Been chopping wood for 30 plus years and never a problem. 1500 bucks worth of crap. Just purchased a 455 husqvana. Shame on you stihl

had a old 029 for many years,[18 at least!], rugged reliable,great saw.,but it was getting a bit long in the tooth. my good wife decided i deserved a new one for my birthday. purchased a m s 391 along with stihl engine oil which gave me a extra 2 year warranty .[lol].it seemed ok, but the bar wear was surprising.after 4 months it blew a hole in piston . neither the agent or stihl aust., wanted to know, as i had obviously, used the wrong fuel mix, used old fuel,or flogged it.all of which is complete nonsense. have reverted to my older, smaller Victa pro, using the same fuel mix, cutting the same fence posts, no problem,.Comment anyone? Class action ??

Purchased new, used about 10 hours over a three year period. Always used Stihl oil and mix rate of 50-1, and never over worked. It died cutting stringybark. Pulled apart, bearings totally failed, major scores on the piston and bore. I’d say the crank is shot as well. Cost $1,100 new and now a piece of junk. Don’t want to throw good money away fixing it as more than likely it will fail again. Stihl have blotted there copy book with me that’s for sure!
Note have a little MS 170, done twice the work and runs like a dream ...

Farmboss died after <100 hrs.
I’ve always considered stihl a high quality brand but I’m done now. Bought this saw because advertised as having the grunt and longevity for farm work. Had it for 5 years, used it sparingly, wrapped it in cotton wool and the dealer said engine is done and you’ll need a new one. Would have been cheaper to buy wood for 5 years. It stihl looks new.... sorry couldn’t help myself.
So much for the “pulling the 20 year old stihl out of the shed and it starts first time” crap they dribble.

I have owned Stihl for over 30 years, I purchased my Farm Boss about 3 years ago, I keep it in a unheated Barn in sub zero Pocono Mountain weather. It always starts easily and is one of the best cutting saws I have ever used. The only thing I do special with this saw is I use the pre-mixed fuel Stihl fuel.

Probably got 10-15 hrs of use out of it. Didn’t use it much but it’s still barely out of warranty. Really like my ms290 but obviously quality has dipped dramatically.

Don't buy Stihl, I bought a stihl MS250 for $695 and motor died after 4 months ( or 10 medium tress cuts) . Stihl dealer said we didnt mixed enough oil and refused to pay the repair motor cost of $475, But we always mixed 100 per 5L. We bought the MS391 while we waiting for the dispute. Buy after few days use, the MS391 wont stop now we have to bring it back to repair. SO DO NOT buy STIHL produsts, waste time

I have owned many chainsaws over last 25 years through our hardwood timber biz, recently bought 3 units 391 and 1st unit lasted 4 weeks when compression died and can see a hole in piston after spark plug removed. all 3 units are not working with same problem, usage is moderate and maintained. enough power but no reliability and Stihl will not support unless we pay money to repair. very poor form. Careful what you buy and as newer Stihl saws too many electrics and lighter wight, not as robust. using my 20 year old 268 Husky rather than 391 with latest features but no performance. by the way my 18 month old 381 is running well!!

Bought the farm boss to cut blanks for turning and slab cutting for furniture. Had a fair bit of work clearing fallen trees after recent cyclone and some cuts of a full tank at a time doing slabs. After 11 months and about 20 hrs work it upped and died. Always used 40 to 1 mix but it had lost power and stopped 10 min into a slab cut,never to go again. Dealer says I cooked it but I would expect it to cope with long cuts at high revs. No fouling of air vents or other contributing factors. Starting always a bit of an issue. Never less than 6-8 pulls and often flooded and needed a rest

Husband very happy, wish we had bought one 20 years ago. Slices through sugar gum like butter, makes the job so much easier. Light to hold and to maneuvers. Received a free chain with it, so wuite a bargain. Wishes he hasn't wasted his time with inferior brands & got one of these years ago

The saw works great but the 2 bolts keep backing out on the muffler. I tried putting lock tight on the bolts but that didn't work either. I'm taking it back to the dealer to see what the problem is. I own 3 other Stihl saws have never had a problem. I think this is a design flaw my other saws have all thred bolts with nuts on the muffler this saw has bolts that go into a small hole in the muffler that are very hard to get to.

Crap chainsaw wouldn't start dealer said wrong fuel mix I said you told me 50/1 . Other 2 chainsaws still going on same fuel mix . They can fix it for $800 wow only used it 6 times .be careful when buying Stihl chainsaws and whatever they say don't use 50/1 mix asking for trouble

Stihl has two bolts that take two nuts supposed to hold the bar in place to enable holding the chain taught on the bar. The system does not work. I can cut just a small amount of brush, or a tree and the chain loosens and until I figured out the cause of this spanking new chain saw, the chain came off the bar several times. I feel cheated by the Manufacturer for building such a poor product.
