• Heavy-Duty Air Filter - This easy accesible filter is designed to handle the high volume of airflow specific to a large professional saw.
  
  
• Improved handle design - The rear handle is asymmetrically designed with comfort inserts for a more stable and less tiring grip.
  
  
• Optimized saw body - No protruding parts, a smooth underside, rounded starter cover and well protected controls make the saw easy to handle.
  
  
• Smart Start® - The engine and starter havs been designed so the machine starts quickly with minimum effort. Resistance in the starter cord is reduced by up to 40%.
  
  
• Adjustable oil pump - Allows you to control oil flow depending on application and weather conditions.
  
  
• Snap-lock cylinder cover - Saves time when changing spark plugs and cleaning.
  
  
• Front handle ergonomics - Better grip and an offset handle reduces fatigue.
  
  
• Magnesium crankcase - Sturdily built crankcase withstands high rpms and
  tough professional use, ensuring a long service life.
  
  
• Three-piece crankshaft - Forged three-piece crankshaft for maximum
  durability for the toughest applications.
  
  
• Air Injection - 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.
  
  
• Side-mounted chain tensioner - Easier access to chain tensioning device.
  
  
• Felling marks - Distinct marks for better felling precision.
  
  
• X-Torq® - Delivers lower fuel consumption and reduced exhaust emission levels
  in accordance with the world´s most stringent environmental regulations.
