OPERATIONAL CHECK:
WARNING
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 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 (8) for leaks and/or rattles. Tighten screws (1 and 4) and nuts (7) as necessary
to prevent rattles. If muffler leaks, replace it.
