Technical Features

  • STIHL ErgoStart: A spring between the starter cord reel and crankshaft relieves the strain when starting, resulting in a convenient starting procedure with practically no excessive pulling on the cord needed.
  • STIHL 2-MIX engine: The two-stroke engine with STIHL 2-MIX technology saves up to 20% of fuel and reduces emissions by up to 70% compared to STIHL 2-stroke engines of the same performance class without 2-MIX technology.
  • Manual fuel pump (Purger): STIHL chainsaws with manual fuel pumps allow improved starting with a reduced number of starting pulls.
  • Side-mounted chain tensioning: Side-mounted chain tensioning makes it easy to tension the chain safely.
  • Tool-free fuel caps: Special caps to open and close the tank cap quickly, easily, and without tools.
  • Service-friendly air filter system: The carburetor can be accessed without tools, so you can clean the air filter in a single step.
  • STIHL anti-vibration system: Precisely calculated buffer zones minimize the transfer of engine and saw chain vibrations to the front and rear handles, allowing the user to save their strength and work longer.
  • Fold-out hook: The fold-out hook serves as a carrying rope attachment for lowering the arborist saw and for security.
  • Compensator: This controller in the carburetor prevents the fuel-air mixture from getting richer as the air filter becomes clogged.
  • Advanced combustion technology: Four overflow channels swirl the fuel-air mix before ignition, allowing for optimum combustion and highly efficient performance.
  • STIHL Ematic System: Compared to conventional bars without Ematic, the STIHL Ematic system reduces the consumption of chain lubricant by up to 50%, depending on the type of wood and the cutting attachment used.
