Excellent cooling capacity for a longer engine lifeOur new cooling system is optimised in every detail to give you a reliable chainsaw for any situation. |
Felling sight to last a lifetimeHaving a perfect sight is critical when using a chainsaw – so we made one that’s permanently molded into the chainsaw for long-lasting felling accuracy. |
AutoTuneAutoTune 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 crankcaseSturdily built crankcase withstands high rpms and tough professional use, ensuring a long service life. |
Snap-lock cylinder coverSaves time when changing spark plugs and cleaning. |
LowVib®System designed to reduce vibration levels to the operator, which lessens fatigue. |
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 pumpAllows you to control oil flow depending on application and weather conditions. |
Visible fuel levelTransparent fuel indicator makes it easy to check fuel level. |
Retained bar nutsThe retaining function prevents loosing the bar nuts. |
Quick-release air filterFacilitates cleaning and replacement of the air filter. |
Retained starter screwsA retaining function prevents the accidental loss of the screws holding the starter. |
