    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 Great Saw Wonderful machine! I am very pleased with my purchase. I like how lightweight and well balanced it is. It is just a fantastic tool. If properly maintained it will last me many years. GO STIHL! September 26, 2016
Rated 5 out of 5 by Light weight but tuff It's been years since I've used a chain saw so I was very pleased with the easy starting, the quick break bar, the power in a small home use saw. Also my dealer was extremely helpful. September 26, 2016
Rated 5 out of 5 by Easy to start, light weight and enough power to handle all the jobs I need it for. Have owned several chain saws over the years, but this is my first Stihl. Maybe if I had purchased one sooner, I could have saved a lot of money and frustration over the years. September 25, 2016
Rated 5 out of 5 by my second Stihl saw don't use bad gas, keep it sharp! starts quick, much lighter than my previous Stihl 14" saw, September 24, 2016
Rated 5 out of 5 by Hercules! Hercules! Well mini Hercules. Great for little jobs. Lots of trees down now the clean up. Perfect little saw for the job. Good quality STIHL saw at a reasonable price. September 23, 2016
Rated 5 out of 5 by AWESOME SAW BEST FOR THE PRICE I HAVE NOW OWNED 4 OF THESE SAWS WE OPERATE THEM COMMERCIALLY FOR LANDSCAPING AND TREE WORK. THEY WORK GREAT (LIKE ALL STIHL SAWS) AND ARE SO INEXPENSIVE THAT WHEN WE FINALLY BREAK THEM WE CAN JUST REPLACE THEM. September 23, 2016
Rated 4 out of 5 by A little hard to start I've only had the saw a month or so, so I really can't speak to its reliability or durability. So far it has cut everything from small limbs to 9 inch limbs with no issues. It is always difficult to get started first thing. Once it is warmed up though it starts the first or second pull every time. September 23, 2016
Rated 4 out of 5 by Great Value / bad oiling design Great value , but oiling system is very finicky . Already burnt one bar up . removed clutch checked gear, filter, hoses , pulled pump . cleaned tank , although the saws barely used .My conclusion is the pump and or passages are simply to small .Ill be looking for a higher volume pump replacement . if you can post a part # that would be sweet . Love the size and ergonomics of it and power is good for the weight . We just "Need more oil Cap'n" September 22, 2016
