You won’t need to clean the filter until you experience a noticeable drop in power and performance. This helps keep the air to fuel ratio on track and constant, allowing the engine to generate maximum power. This clever design delivers the correct amount of fuel to the carburetor based on the quantity and quality of air being processed through the filter. The MS 251 also features a compensator that prevents the air-fuel mixture from getting too rich as the air filter clogs. It works by ejecting larger dust and debris particles from the filter before re-routing the filtered air via the pre-separator duct. The air filter is often the source of maintenance issues, and extending its life saves the buyer both time and money by avoiding these problems further down the line. Stihl has developed and included an advanced air filtration system on the MS 251 that dramatically extends the life of the engine’s air filter. This greatly reduces their impact on the user’s body and allows them to continue to work over extended periods. Stihl has designed and incorporated a highly effective anti-vibration system that dampens the oscillations produced by the gas engine.
