FINAL TESTING AND ADJUSTMENTS - CONTINUED
EXHAUST GAS CAN KILL YOU
Exhaust gas is without color or smell, but can kill you. Breathing exhaust gas produces
symptoms of headache, dizziness, loss of muscular control, a sleepy feeling, and
coma. Brain damage or death can result from heavy exposure of exhaust fumes of fuel-
burning internal combustion engines. Exhaust gases can become dangerously concen-
trated under conditions of no air movement. Precautions must be followed to ensure
crew safety when the engine of any vehicle is operated for any purpose.
DO NOT operate vehicle engine inside building unless ample ventilation is available.
DO NOT idle engine for long periods without ventilator blower operating.
DO NOT drive any vehicle with inspection plates, cover plates, or engine compart-
ment doors removed unless necessary for maintenance purposes.
BE ALERT at all times during vehicle operation for exhaust odors and exposure symp
toms If either is present, IMMEDIATELY VENTILATE personnel compartments. If
symptoms persist, remove affected crew to fresh air; keep warm; DO NOT PERMIT
PHYSICAL EXERCISE; and, if necessary, give artificial respiration.
FOR ARTIFICIAL RESPIRATION, REFER TO FM 21-11.
BE AWARE; the field protective mask for chemical-biological-radiological (CBR)
protection will not protect you from exhaust gas fumes.
THE BEST DEFENSE AGAINST ENGINE EXHAUST FUMES IS GOOD VENTILATION.
To prevent damage to the turbocharger, do not accelerate the engine above 1000 rpm
until the reading on the oil pressure gage indicates normal oil pressure at idle speed.
12. Fuel pump (1)
Set for idle speed.
After engine starts, run at approximately 800 rpm, disconnect turbocharger oil drain
line, and observe oil drain. Oil should flow in 10 to 15 seconds. If no oil flows in 30
seconds, shut down engine and correct fault. Reconnect oil drain line when flow is
The manual override knob on forward end of electric shutdown valve allows valve to be
opened if power is not available during testing. To use, open valve by turning knob fully
clockwise. Each time engine is started, see Preliminary Starting Procedures,
