Our most advanced saw for demanding professional use. It features our new X-Torq® engine that provides high torque over a very wide rpm range, combined with low fuel consumption and low exhaust emission levels. Ergonomically improved handles reduce fatigue. AutoTune always gives optimal engine setting, Smart Start® provides easy starting and Air Injection makes the saw run stronger and longer. Heated handles increases comfort in cold conditions.
Efficient heating coils in the front and rear handles make the saw more comfortable to use in cold and damp conditions.
AutoTune gives optimal engine performance throughout automatic engine setting. No time spent on carburettor adjustments. It compensates for different fuels, altitude, humidity, temperature and clogged air filter.
The engine and starter have been designed so the machine starts quickly with minimum effort. Resistance in the starter cord is reduced by up to 40%.
Inertia chain brake
Effective inertia-activated chain brake.
Deliver lower fuel consumption and reduced exhaust emission levels in accordance with the world´s most stringent environmental regulations.
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 reduce the risk of engine flooding.
