Anti-Vibration System
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. -
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 All4mtb from Love this saw! I use it for trimming trees around the house, around the farm and for cutting fallen trees out of local mountain biking trails. It is light enough to carry out on the trails when we have to walk for a ways to cut a tree that is blocking the trail. Great saw!!

Rated 4 out of 5 by tm55 from good value on sale at $159. Reliable, quick starting, light and easy to operate. Use of a lot of plastic parts may be a factor in long-term durability of the saw. I keep my equipment maintained and use for many years. Hopefully, this tool will hold up under light to moderate home use.

Rated 5 out of 5 by AdamK from Great homeowner saw! I bought the saw to clear out trees and brush for a shed. I ran the saw for 2 days few hours each day and had no issues. First time chainsaw user and I was impressed how easily it handles. Chain got dull after I cut into some dirt but I replaced the chain for a few dollars and it runs as new.
