Airflow & Engine Protection
The air guide shroud is part of the engine housing and airflow system. It helps direct cooling air around the engine while providing protection for internal components.
A damaged, cracked, or missing shroud can interfere with the intended airflow and protection provided by the engine housing. Replacing the component with the correct OEM part helps maintain the original configuration of the equipment.
Genuine STIHL Replacement Part
The 4149 080 0903 is designed as a genuine STIHL replacement component for the listed equipment.
Since several of the compatible models have serial-number restrictions, matching only the model name may not be sufficient. Always compare your machine’s model, serial number, and parts diagram before purchasing.
Installation & Maintenance
Before replacing the air guide shroud:
-
Stop the engine and allow it to cool completely.
-
Disconnect the spark plug boot when applicable.
-
Clean dirt and debris from the surrounding engine housing.
-
Remove the existing shroud according to the appropriate STIHL service procedure.
-
Inspect nearby components for damage or excessive wear.
-
Install the replacement shroud in the correct position.
-
Reinstall and secure all fasteners.
-
Make sure cooling-air passages are clear.
-
Verify the housing is correctly assembled before starting the equipment.
For internal engine repairs or service requiring specialized procedures, use a qualified technician when appropriate.
