(8) Check that charging indicator light has gone out. This indicates batteries are being adequately charged by
alternator.
(9) Adjust engine speed to 2800 RPM and lock THROTTLE T-handle, then prime the centrifugal pump as
described below.
f. Priming Centrifugal Pump.
WARNING
Carbon monoxide is produced by the internal combustion engine of this pump. Death may result
if personnel fail to observe safety precautions.
Carbon monoxide is a colorless, odorless, deadly poisonous gas which, when breathed, deprives
the body of oxygen and causes suffocation. Exposure to air contaminated with carbon monoxide
produces symptoms of headache, dizziness, loss of muscle control, or apparent drowsiness.
Coma, permanent brain damage, or death can result from severe exposure.
Carbon monoxide occurs in the exhaust fumes of internal combustion engines and becomes
dangerously concentrated 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 maintaining 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 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.
Prime the centrifugal pump as soon as possible after engine starts. Rotation of impeller without
water in volute will damage pump components.
Pump shall prime within 1 minute. If pump volute does not fill with water, check suction hose
connection and suction hose for leaks. Be sure that suction hose end is completely immersed in
water to be pumped.
(1) Open cock valve.
(2) Swing handle over onto exhaust valve.
