GENERAL INFORMATION
To meet the various requirements of the original
equipment manufacturers (OEMs), some
engines are shipped without exhaust systems.
Exhaust systems for these engines are serviced
and supplied by the OEM. Contact the original
equipm ent manufacturer for speci fic service
information on non-Briggs & Stratton exhaust
systems.
CAUTION:
When replacing exhaust system
components, replacement parts must be the
same as originally specified by the OEM. This
may include some mounting brackets and
hardware. Follow the procedures recommended
by the OEM for disassembly and assembly.

whenever the exhaust system is disassembled.
Never reinstall broken or damaged components.

can occur on contact.
•
Allow muffler, engine cylinder finds and
radiator to cool before touching.
•
Remove accumulated combustibles
from muffler area and cylind er area.
