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 engine become concentrated with poor
ventilation. Operate engine in a ventilated area only.
While running engine, be alert for fumes. Keep area
ventilated. 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 (9) for leaks and/or rattles. Tighten screws (1 and 4) and nuts (8) as necessary to
prevent rattles. If muffler leaks, replace it.
