When an engine is running it continuously takes in air. This air passes through a filter before it reaches the engine, in order to guarantee that the combustion process runs as smoothly as possible, and to keep wear and tear to a minimum. This is to filter out unwanted particles such as concrete dust, wood splinters and other fine debris from the surrounding air and to stop them from entering the engine, where they can easily cause damage. That’s why many STIHL chainsaws and all STIHL cut-off machines include an innovative long-life air filter system.

The innovative cyclone routing system means no need for daily filter cleaning and a much longer filter service life. This is how the air filter system works in detail:
Long-life air filter systems offer a whole host of advantages.
