Description
Overview:
This Service Kit for Stihl FS38, FS45, FS55 brushcutters (OEM 4140 007 4100) is a genuine Stihl maintenance pack designed to restore reliable starting and clean running. It combines a fleece air filter, a BPMR7A spark plug, and an in‐tank fuel filter to address the three essentials of combustion: air, spark, and fuel. The air filter uses fleece media to trap fine dust typical of grass and light brush work, while the fuel filter helps protect the carburettor from debris. The spark plug is matched to Stihl small two‐stroke engines for consistent ignition. Suitable for popular machines such as the FS38 and FS45, this kit supports routine servicing at home or on site. Not suitable for 2‐MIX engines; for those, use 4140 007 4103.
