Delivers lower fuel consumption and reduced exhaust emission levels in accordance with the world´s most stringent environmental regulations.
AutoTune gives optimal engine performance throughout automatic engine settings. No time spent on carburettor adjustments. It compensates for different fuels, altitude, humidity, temperature and clogged air filter.
Rapid acceleration and higher chain speed for best limbing performance.
Extends the interval between filter cleaning, improving efficiency and increases engine life.
Two mass principle
Effectively minimising vibrations by isolating the engine from the handles reducing operator fatigue.
Adjustable oil pump
Adjustable oil pump allows you to adjust chain lubrication to suit all working applications.
Quick-release air filter
Facilitates cleaning and replacement of the air filter.
Combined choke/stop control
Combined choke/stop control allow for easier starting and reduces the risk of engine flooding.
