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.
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.
Magnesium crankcase
Sturdily built crankcase withstands high rpms and tough professional use, ensuring a long service life.
Smart Start®
The engine and starter have been designed so the machine starts quickly with minimum effort.
Snap-lock cylinder cover
Saves time when changing spark plugs and cleaning.
Visible fuel level
Transparent fuel indicator makes it easy to check fuel level.
Retained bar nuts
The retaining function prevents loosing the bar nuts.
Quick-release air filter
Facilitates cleaning and replacement of the air filter.
Retained starter screws
The retaining function prevents loosing the screws holding the starter.
Flip up tank caps
Easy to open and secure firmly, even when wearing thick winter gloves.
LowVib®
System designed to reduce vibration levels to the operator, which lessens fatigue.
Felling sight to last a lifetime
Perfect sight is critical when felling – so we made one that will outlast the chainsaw itself.
Air Injection®
Centrifugal air cleaning system removes larger dust and debris particles before reaching the air filter. This results in reduced air filter cleanings and improved engine life.
Adjustable oil pump
Allows you to control oil flow depending on application and weather conditions.
Easy to start
Combined start/stop switch and fuel pump make the saw very easy to start.
Side-mounted chain tensioner
Easier access to chain tensioning device.
Slimmed-down design
Low, slender saw body makes the chainsaw easy and convenient to handle in any situation.
X-Torq®
Delivers lower fuel consumption and reduced exhaust emission levels in accordance with the world´s most stringent environmental regulations.
Three-piece crankshaft
Forged three-piece crankshaft for maximum durability for the toughest applications.
