Install heat shield (3).

OPERATIONAL CHECK:
Touching exhaust system during test can cause severe burns.
Exposure to exhaust gases produces symptoms of headache,
dizziness, loss of muscular control, drowsiness, or coma.
Brain damage or death can result from severe exposure.
Fumes from engines become concentrated with poor venti-
lation. Operate engine in a ventilated area only.
While running engine, be alert for fumes. Keep area venti-
lated. If someone is overcome, expose to fresh air; keep
warm and still; give artificial respiration if needed. Seek
medical attention. Administer oxygen, if available.
GOOD VENTILATION IS THE BEST DEFENSE AGAINST
EXHAUST POISONING.
Start engine and observe muffler (8) for leaks and/or rattles. Tighten screws (1 and 4) and nuts
(7) as necessary to prevent rattles. If muffler leaks, replace it.
