Application Notes
On many FS, FC, KM, BT, and FB models, the 4180 141 8602 Hose is shown within the muffler and air-filter assembly. Proper hose routing is important because an incorrectly installed or damaged hose can affect the engine's air system.
For HT models, the parts catalog may identify the hose based on the engine configuration rather than the same assembly description used on the FS models.
Signs the Hose May Need Replacement
Inspect the hose if you notice:
-
Cracks or splits.
-
Hardened or brittle rubber.
-
Visible deformation.
-
Loose connections.
-
Air leakage.
-
Poor engine performance.
-
Difficulty maintaining engine speed.
-
Damage caused by heat, vibration, or age.
Why Replace the Hose?
Engine hoses are exposed to heat, vibration, fuel-system conditions, and normal wear. Over time, rubber components can become brittle or develop cracks.
Replacing a damaged hose with the correct STIHL OEM component helps restore the original connection and routing within the engine assembly.
