OPERATIONAL CHECK:
WARNING
Muffler and related components get hot enough during pump operation to cause severe burns.
Avoid contact with muffler and related components during checks described in this text.
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.
