Maintain the legendary "Farm Boss" performance of your equipment with the STIHL Service Kit . This comprehensive maintenance set is specifically engineered for the STIHL MS 290, MS 310, and MS 390 chainsaws. Proactive servicing is the most effective way to protect your engine from fine dust and debris, ensuring reliable starts and consistent cutting power for demanding wood-cutting tasks.
The STIHL Service Kit provides a convenient, all-in-one solution for your seasonal tune-up. It includes a high-capacity Air Filter, a specialized Fuel Filter, and a matched Spark Plug. By replacing these three essential components together, you restore the factory-spec air-to-fuel ratio, helping your saw run cooler and more efficiently during heavy-duty use.
Maintenance Tip: To prevent power loss and increase engine longevity, STIHL recommends installing a fresh service kit every 25 to 50 hours of operation.
