Features
Excellent cooling capacity for a longer engine life
Our new cooling system is optimized in every detail to give you a reliable chainsaw for any situation.
Felling sight to last a lifetime
Perfect sight is critical when felling – so we made one that will outlast the chainsaw itself.
Retained bar nuts
The retaining function prevents loosing the bar nuts.
LowVib® Technology
Dampeners between the engine and chassis significantly reduce vibrations so you can work more comfortably
Low, slender saw body makes the chainsaw easy and convenient to handle in any situation.
Air Injection™ Technology
Centrifugal air cleaning system expels larger dust and debris particles before they reach the air filter to help improve engine life
Flip up tank caps
Easy to open and secure firmly, even when wearing thick winter gloves.
Quick-release air filter
Facilitates cleaning and replacement of the air filter.
Magnesium crankcase
Sturdily built crankcase withstands high rpms and tough professional use, ensuring a long service life.
Retained starter screws
The retaining function prevents loosing the screws holding the starter.
Snap-lock cylinder cover
Saves time when changing spark plugs and cleaning.
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.
Powerful and Efficient X-TORQ® Engine
Powerful X-TORQ® engine reduces emissions by up to 60% and increases fuel efficiency by up to 20%
Fuel Indicator
Transparent fuel indicator makes it easy to check fuel level
Three-piece crankshaft
Forged three-piece crankshaft for maximum durability for the toughest applications.
Side-mounted chain tensioner
Easier access to chain tensioning device.
Adjustable oil pump
Allows you to control oil flow depending on application and weather conditions.
