2-6. OPERATING PROCEDURE (Continued)
WARNING
CARBON MONOXIDE (EXHAUST GAS) CAN KILL YOU
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. If someone is overcome, expose to fresh air; keep warm
and still; give artificial respiration if needed. (Refer to FM21-11.) Seek medical attention.
Administer oxygen, if available. GOOD VENTILATION IS THE BEST DEFENSE AGAINST EXHAUST
POISONING.
Do not smoke within 50 feet (15.2 m) of an operating pump unit. Smoking within this area creates
a fire and explosion hazard. All personnel within 15 feet (4.57 m) of an operating centrifugal pump
unit must wear approved ear protection equipment. Failure to do so may result in impairment or
loss of hearing.
CAUTION
Be sure the pump volute is filled with liquid to the bottom of the suction port before starting the
engine. The pump will not prime when dry. Extended operation of a dry pump will destroy the
seal assembly and cause overheating which could seriously damage the pump. Do not use ether
start kit except in extremely cold weather when engine will not start. See paragraph 2-8. To
prevent starter from overheating, do not crank engine with starter for more than 10 seconds.
Battery life will be lengthened if 60 seconds is allowed to elapse between starting attempts. Under
any condition, if engine does not start on initial attempt, allow engine rotation to stop completely
before again engaging starter.
NOTE
Be sure priming port dust cap is securely in place on the pump body.
