Better chip ejection avoids clogging
The clutch cover is designed to optimise rapid, safe saw chip ejection. Prevents clogging, even when cutting long fibre wood.
Better manoeuvrability provides full control
The front handle bar position is close to the center of gravity, giving you better cutting control.
Air Injection filters 98% of incoming dust
Gives you full working days with maintained performance and less wear on the engine.
10 times quicker air/fuel mix adjustment
AutoTune™ ensures a correctly tuned engine setting and optimised engine performance in all conditions.
Low vibrations
Husqvarna's anti vibration system efficiently separates your hands from the vibrations generated by the engine and the cutting equipment. This is to protect your body but also to reduce the fatigue in your arms and hands and in the end of the day contribute to make your workday more productive.
Soft cut-out system
The innovative system for engine control is designed to provide a long engine life. The system monitors the engine and assures that the engine always is protected from over-revving.
Visible fuel level
Transparent fuel indicator makes it easy to check fuel level.
Flip up tank caps
Easy to open and secure firmly, even when wearing thick winter gloves.
Felling sight to last a lifetime
Perfect sight is critical when felling - so we made one that will outlast the chainsaw itself.
AutoTune
AutoTune gives optimum engine performance throughout automatic engine settings.
No time spent on carburettor 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. Resistance in the starter cord is reduced by up to 40%.
X-Torq®
Delivers lower fuel consumption and reduced exhaust emission levels in accordance with the world's most stringent environmental regulations.
