  Long life air filter

  Pre-separating the STIHL air filter offloads the following filter elements and significantly lengthens filter cleaning intervals. Thus, STIHL chainsaws equipped with pre-separated long-life air filters have a longer service life than those equipped with standard filter systems. (View image)

  STIHL 2-MIX engine with air scavenging

  With the gas scavenging by air, a layer of clean fuel air is created between the already burned mixture in the combustion chamber and the fresh charge in the precompression crankcase. Advantage: fewer fuel losses, more ecological and up to 20% less fuel consumption compared to conventional two-stroke engines (See clarifying image).

  STIHL Side Chain Tensioner

  STIHL Ematic System

  This system reduces the consumption of chain adhesive oil. It consists of the Ematic bar, the Oilomatic chain. With these components, the chain oil reaches where it is really needed without losses. In this way, chain oil consumption can be reduced by up to 50%.

  STIHL Carburetor Preheat

  During the cold winter you can also rely on STIHL chainsaws: with winter operation the preheated suction air enters the carburettor preventing frost. You only have to change a simple lever to put the service of winter or summer. (View image)
