  • 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.
  • 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.
  • System designed to reduce vibration levels to the operator, which lessens fatigue.
  • Low, slender saw body makes the chainsaw easy and convenient to handle in any situation.
  • 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.
  • Flip-up fuel tank caps are easy to open and secure firmly, even when wearing thick winter gloves.
  • Sturdily built crankcase withstands high rpms and tough professional use, ensuring a long service life.
  • 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.
  • 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.
  • The large transparent tank window makes it quick and easy to check the fuel level at a glance without opening the fuel  tank’s lid.

* Free Shipping on All Saws – Please note your new saw will ship with the bar and chain un-mounted and may arrive in multiple boxes/shipments.

* Returns will NOT be accepted for any units that have been gassed or oiled. Contact customer service for help returning any unused items or for information relating to warranty claims.
