Starting and Warmup (+32F). (Cont)

TM 9-2320-273-10

CAUTION

If the engine fails to start within 15 seconds, release

the START button and allow the starting motor to cool

for two minutes before you try again to start the engine.

Never depress the START button while the starting

motor is still running from the previous try. If the

engine fails to start after four attempts, refer to

Table 3-1, Troubleshooting Procedures. Failure to

follow these precautions can result in serious damage

to the starting motor.

f. Press the START button while slightly depressing the accelerator pedal . The engine

should start. The engine temperature warning light should illuminate when the starter

button is depressed. Do not depress Engine Start button for more than 15 seconds

with two minute intervals between crankings.

CAUTION

During warmup do not operate the engine above 1000

rpm until normal engine idle speed oil pressure is indi-

cated on the Engine Oil Pressure gage. This allows time

for oil circulation to reach the turbocharger and for engine

parts to warm up gradually. (Range at idle speed is

5-20 psi.)

g. After the engine starts, maintain an idle speed of 580 to 650 rpm.

CAUTION

If there is no indication of oil pressure after 10 seconds

at idle, shut down the engine immediately by turning the

key switch to OFF and refer to Table 3-1 for trouble-

shooting and corrective action. DO NOT ATTEMPT TO

RESTART THE ENGINE UNTIL THE PROBLEM HAS

BEEN CORRECTED.

h. Simultaneously with step g., observe the oil pressure gage. At low idle speed the

gage should indicate 5-20 psi at normal operating temperature.
