    STIHL has developed a system for minimizing the vibration levels of handheld outdoor power equipment. The STIHL anti-vibration system helps reduce operator fatigue and provides a more comfortable working experience.

    IntelliCarb™ Compensating Carburetor
    The IntelliCarb™ Compensating Carburetor is designed to automatically adjust the air/fuel ratio when the air filter becomes restricted or partially clogged and maintains the engine’s correct RPM. IntelliCarb™ uses air from the clean side of the air filter to control the diaphragm and flow of fuel. As the air filter becomes dirty and less air is available for the carburetor, the IntelliCarb™ system adjusts the fuel flow to compensate for the decrease in air flow. This is in contrast to typical carburetors that utilize this air from the “dirty” side of the air box.
  • Zoom
    Ematic™ Lubrication System
    The Ematic™ guide bar, when used with STIHL OILOMATIC® saw chain, will provide proper lubrication and less oil consumption than conventional methods. The system works because two ramps, strategically placed in the guide bar rail, help contain the flow of oil and direct all lubrication to the sliding faces of the bar and chain links as well as the rivets and driver holes, which in turn can reduce bar oil consumption up to 50%.

Rated 5 out of 5 by from Great Saw for the job I bought this saw at the hardware store. Even though I've been running saws for 35 years, the salesman wanted to go over the saw with me. I didn't mind at all. He showed me how to correctly start it so there wouldn't be any problems. He also assured me to bring it back if I had any issues.I bought this saw for light work such as small trees and limbs. I have a couple of bigger and heavier saws for large work. This is a great saw for what I needed. I have had it for 2 months and have ran it for at least 30 hours. No problems what so ever.If proper starting procedure and maintenance is followed this saw should not give any troubles. I would definitely recommend this saw.

Rated 5 out of 5 by from Everything I need Pretty powerful little saw actually. Great bang for the buck. Cut down a full size 40-45 foot pine tree from top to bottom no hesitation. Recommended for anyone

Rated 1 out of 5 by from I am not pleased at all. My saw was a gift for my birthday bought by my wife. We have a lot of tallow (chicken) trees in the horse pasture that i wanted to take down. I used the saw for maybe 3 hours and the chain came off and i couldn’t get it back going. I got it all put back together and then it just would not run, idle, run the chain, nothing ! My father in law, who is very handy even worked on it. We could not get it back going and i returned it on Monday. I was told that they do not do returns and will fix it for me. I do not recommend this saw at all and customer service where it was purchased was not good and extremely rude about the questions i had. I just hate the fact that I’m stuck with a brand new saw that is already giving trouble. Not happy at all.

Rated 5 out of 5 by from Awesome Saw Have owned other manufacture saws and they in no way compare to this one. Yes it is a little smaller, but in no way lacks in power and ability. Had 6 huge white oaks taken down and used this saw to buck all of it. Amazed at how easy it cut and quality of the saw. Wish I would have just bought a Stihl to begin with. Worth every penny; enjoy!

Rated 2 out of 5 by from Good for saplings Purchased at my local truvalue, Not know much about saws the sales associate sold me what was on sale, not what I needed for the job. It’s a good saw for saplings or very small trees, other than that it Boggs down. I wish I purchased a bigger saw
