WARNING
Carbon monoxide occurs in the exhaust fumes of internal
combustion engines and becomes dangerously concen-
trated under conditions of inadequate ventilation. Observe
the following safety precautions whenever the engine is
running:
Operate engine in a ventilated area only.
Do not idle the engine for long periods without maintain-
ing adequate ventilation.
Be alert at all times for exhaust odors and exposure
symptoms.
Be aware: the field protective mask for chemical
biological radiological (CBR) protection will not protect
you from carbon monoxide poisoning.
Expose victims to fresh air, keep warm, and do not permit
physical exercise. For artificial respiration, refer to
FM21-11. Seek medical attention. Administer oxygen, if
available.
GOOD VENTILATION IS THE BEST DEFENSE AGAINST
EXHAUST POISONING.
Priming discharge mixture of water and exhaust gases may
cause severe burns or injury. Wear gloves and safety
glasses when priming pump.
Stand clear of venturi during priming.
CAUTION
Prime the centrifugal pump as soon as possible after engine
starts. Rotation of impeller without water in volute will
damage pump components.
15. Engine,
Start engine. Ammeter on control panel should in-
alternator,
dicate zero or a positive current flow. If ammeter in-
and ammeter
dicates a negative current flow, check batteries and
electrical system (paragraphs 4-13 and 4-15). If bat-
tery and electrical systems are operating properly,
replace alternator. If condition still exists, recheck
batteries and electrical system, then replace am-
meter in accordance with paragraph 4-16.
