Stihl Service Kit 15 (MS 231, MS 251)

STIHL Service Kit 15 for MS 231 & MS 251

The STIHL Service Kit 15 helps you perform essential maintenance on MS 231 and MS 251 chainsaws with ease. It includes a fleece air filter, spark plug, and fuel filter—everything you need to support engine performance and prolong saw life.

Efficient Fleece Air Filter

The kit includes a fleece-style air filter that captures coarse dust on its surface and finer particles within its layers. As a result, it keeps abrasive debris out of the engine, helping to maintain fuel efficiency and protect internal components.

Reliable Spark Plug

Also included is a genuine spark plug that promotes clean combustion and easier starts. Moreover, regular replacement ensures smoother power delivery and reduces misfire risk under varied conditions.

Protective Fuel Filter

The fuel filter prevents particles from entering the fuel system. Therefore, it safeguards your carburetor and engine, decreasing the chance of poor running conditions or costly repairs.

Quick DIY Maintenance

You don’t need extra tools to complete the service—just use the combination wrench that came with your chainsaw and the included cardboard hook for fuel filter removal. Consequently, you can perform maintenance quickly, whether you're in the field or the workshop.

Benefits of Regular Service

By fitting fresh filters and a spark plug at the recommended interval, you’ll restore smooth operation, improve fuel economy, and reduce emissions. Ultimately, regular servicing helps extend the lifespan of your MS 231 or MS 251 chainsaw.
