NOTE: If engine is being started at beginning of work shift be sure to perform all “CHECKS AND
SERVICES BEFORE STARTING ENGINE” (page l2).
ENGINE OPERATION
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. 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.
Starting Engine
NOTE: Engine will not start unless forward/reverse
lever is in neutral.
Turn ignition key clockwise to ON position.
Turning Ignition switch to START position
while engine flywheel is rotating can cause
serious damage to engine and/or starting
motor.
Depress accelerator pedal approximately 1/4 to
1/3 of travel.
Turn ignition switch to START position to engage
starting motor. Release key immediately when
Cold Weather Starting Aids
Diesel engine ignition is accomplished by heat
generated when fuel 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
charging system.
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
and correct problem before continuing.

NOTE: If temperature requires the use of a starting
installed ether starting aid, depress button and release
while cranking engine. Repeat if necessary.
CAUTION: Excessive other can cause serious
damage to engine.
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
malfunctioning before restarting engine.
Minimum pressure at oixrating temperature:
Low idle: ...................................................... 10 psi (69kPa)
Full throttle under load: ............................... 30 psi (207kPa)
Warm up engine at approximately 1/2 throttle
until engine coolant temperature reaches
operating range.
specific instructions for their use in this manual.
Carefully follow instructions furnished with your
starting aid.
If you use a starting aid employing ether or a
similar subtance pay particular attention to
manufacturer’s warnings.
Avoid prolonged Idling. Idling causes engine
temperature to drop and this permits formation of
heavy carbon deposits and dilution of lubricating oil
by incompletely burned fuel. If the engine is not
being used, turn it off.
Always keep engine covers closed while
engine is running.
