GENERAL INFORMATION

To meet the various requirements of the original
equipment manufacturers (OEMs), some
engines are shipped without exhaust systems.

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.

DANGER
Running engines produce heat.
Temperature of muffler and surrounding
areas can reach 150°F (65°C). Severe burns
can occur on contact.
•
Allow muffler, engine cylinder finds and
radiator to cool before touching.
•
Remove accumulated combustibles
from muffler area and cylinder area.
•
Install and maintain in working order a
spark arrestor before using equipment
on forest-covered, brush-covered
unimproved land. The state of
California requires this (Section 4442
