c. Starting Procedures.

During cold weather,

when ambient temperature is below 30 degrees

F, use engine manifold flame heaters to start

engine.

Note.

Do not attempt an engine start until the

fuel shutoff solenoid is connected and ascer-

tained to be operative.

Caution:

Do not operate the starter motor

continuously for more than one minute. Allow a

two-minute cool-off period before re-energizing

the starter.

(1) Remove pipe plug (F, fig. 6 245 or 8-1),

purge system and bleed the secondary fuel filter

or water separator filter to remove trapped air.

Install pipe plug.

(2) Crank the engine several revolutions

with the fuel shutoff switch in the “OFF ”

position to make certain the engine is no t

hydrostatically locked and is otherwise free.

(3) Turn on the master switch.

(4) Start engine by operating electri c

starting motor with throttle in idle position

(Refer

to

Caution,

above.)

(5) When engine oil pressure does not reach

the minimum 15 psi pressure within 20 seconds,

STOP THE ENGINE IMMEDIATELY

b y

holding the fuel shutoff switch in the “OFF”

position. Determine the cause of low pressure.

Refer to troubleshooting, paragraph 3-9.

Note.

After starting engine, run at idle, 675

to 725 rpm, for five minutes to permit the engine

to warm up and to circulate the oil. Check oil

level and add sufficient oil to bring oil level to

“FULL” mark on oil level gage. Oil level must

be determined with engine idling. Check all

items vital to safe engine operation, such as fuel

lines, oil lines, oil pressure, throttle control,

mounting bolts, coupling, thermocouple harness,

etc.

d. Run-in Schedule.

An overhauled engin e

should be started and tested in accordance with

the schedule (table 8-1).

e. Performance Curve.

Figure 8-3 is a mean

performance curve. A variation of

is

acceptable.
