Overview:
This fan housing is a Genuine Stihl replacement part designed to protect the cooling fan and guide airflow on Stihl petrol hedge trimmers. Made from durable, impact‐resistant moulded plastic in the Stihl orange finish, it shields the flywheel fan from debris and knocks while helping to channel cooling air around the engine for reliable running. It is a direct-fit OEM component for HS 81 RC‐E and HS 81 TC‐E models, and is supplied to Stihl specification under MPN 4237 080 1812 (42370801812). Use it to replace cracked, warped, or missing housings and restore safe operation, correct airflow, and proper guard coverage around the fan area on professional and domestic hedge trimmers.
