Details
- Fully Covered by Husqvarna's 2-year commercial warranty - the longest in the industry!
- The new cooling system is optimized in every detail to give you a reliable chainsaw for any situation.
- 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.
- Sturdily built crankcase withstands high rpms and tough professional use, ensuring a long service life.
- The engine and starter have been designed so the machine starts quickly with minimum effort.
- Quick-release air filter facilitates cleaning and replacement of the air filter.
- System designed to reduce vibration levels to the operator, which lessens fatigue.
- Having 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.
- 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.
- The powerful and efficient X-Torq® engine cuts both engine emissions and fuel consumption, improving your working environment and saving you money at the gas pump.
