Features
AutoTune
AutoTune gives optimal engine performance throughout automatic engine setting. No time spent on carburetor adjustments. It compensates for different fuels, altitude, humidity, temperature and clogged air filter.
Air Injection™ Technology
Centrifugal air cleaning system expels larger dust and debris particles before they reach the air filter to help improve engine life
Powerful and Efficient X-TORQ® Engine
Powerful X-TORQ® engine reduces emissions by up to 60% and increases fuel efficiency by up to 20%
LowVib® Technology
Dampeners between the engine and chassis significantly reduce vibrations so you can work more comfortably
Easy to start
Combined start/stop switch and fuel pump make the saw very easy to start.
Easy to start
