Starting Engine

Check to be sure that all controls are in neutral
and that all electrical components (lights, heater,
defroster, etc.) are turned off. Set parking brake.
Depress accelerator pedal approximately 1/4 to
1/3 o f travel from top.
Insert ignition key and turn clockwise to ON
position.

ENGINE OPERATION

NOTE:

If engine is being started at beginning of work shift be sure to perform all “CHECKS AND

SERVICES BEFORE STARTING ENGINE” (page 12).

Engaging starter motor while engine fly-
wheel is rotating can cause serious damage
to engine and/or starting motor.

NOTE: If temperature requires the use of a starting
installed ether starting aid,depress ether button one

Diesel engine ignition is accomplished by heat
generated when fuel/air mixture is compressed
within the cylinders. Because this heat may be
insufficient to start a cold engine in cold weather,
the use of starting aids has become common practice.

Because of the wide variety of starting aids available
it would be impractical to attempt to provide.

Normal Engine Operation

Observe gages frequently to be sure all engine
systems are functioning properly.

The ammeter shows the charge/discharge rate of the
battery charging system. With the engine running, a
discharge reading (-) or a continuing high charge
reading (+) indicates a problem in the battery
c h a r g i n g s y s t e m .

Be alert for unusual noises or vibration.

When

an unusual condition is noticed, stop machine in a
safe position and shut off engine. Determine cause

time while cranking engine. Repeat if necessary. If
you use a different starting aid, be sure to follow
manufacturer ’s instructions carefully. Excessive
ether may damage engine.

Turn key fully clockwise to engage starting
motor. Release key immediately when engine
starts. If engine fails to start within 20 seconds,
release key and allow starting motor to cool for a
few minutes before trying again.

After engine starts, observe oil pressure gage. If
gage remains on zero for more than ten seconds,
stop engine and determine cause.Correct cause of
malfunction before restarting engine. Normal
engine oil pressure (warm) should be in range of
35 - 50 psi (241 - 345 kPa).

Warm up engine at approximately l /2 throttle
until engine coolant temperature reaches
o p e r a t i n g r a n g e o f 1 8 0 - 2 0 0 ° F. ( 8 2 - 9 3 ° C . ) .

Avoid prolonged idling.

Idling causes engine

temperature to drop and this permits formation of
heavy carbon deposits and dilution of lubricating oil
by imcompletely burned fuel. If the engine is not
