Appearance Care
Exhaust Pipe and Muffler
Maintenance
Refer to Saf ety Precautions
The exhaust pipe and muffler are stainless
steel but may become stained by mud or
dust.
To remove mud or dust, use a wet sponge
and a liquid kitchen abrasive, then rinse
well with clean water. Dry with chamois
or a soft towel.
If necessary, remove heat stains by using a
commercially available fine texture
compound. Then rinse by the same
manner as removing mud or dust.
