OPERATION
PRE-STARTING
Preparations for the initial and each additional star-
ting operation should include careful checks of the
oil,
fuel,
cooling, and electrical systems. The cylinder
air housing door should be closed with all airshrouds
in place.
Before generator set is put in operation, check all
components for mechanical security. If an abnormal
condition,
defective part, or operating difficulty is
detected,
repair or service as required. Thegenerator
set should be kept free of dust, dirt, and spilled oil or
fuel.
Be sure proper operating procedure is followed.
Crankcase Oil: Use an oil with the API designation
CD/SD or CD/SE. However, to reduce oil consump-
tion to anormal level intheshortesttimepossibleona
new or rebuilt engine, use CC oil for the first fill only
(50 hours). Then use the recommended oil only.
Select the correct SAE grade oil by referring to the
following:
Above 30°
F
SAE 30
0
o
F to 30°
F
SAE 10W or 5W-30
Below 0
o
F SAE 5W-30
Multigrade oils are recommended for temperature of
30°
F
and below, but they are not recommended for
temperatures above 30°F. When adding oil between
oil changes, it is preferable to use the same brand as
various brands of oil may not be compatible when
mixed together.
Recommended Fuel: Although number 2 diesel fuel
gives the best economy for most operating
con-
ditions, number 1 diesel fuel can be used:
1.
When ambient temperatures are below 32°F;
2.
During long periods of light engine
load;
or,
3. If preferred by user.
Uselowsulfurcontentfuel having apourpoint (ability
to filter) of at least 10
o
F below the lowest expected
temperature. Keep the fuel clean and protected from
adverse weather. Leave some room for expansion
when filling the fuel tank.

Due to the precise tolerances of diesel injec-

tion systems, it is extremely important the fuel
be kept clean. Dirt in the system can cause severe damage to both
the injection pump and the injection nozzles.
Bleed air from fuel system as follows: Disconnect the
fuel return line. See Figure 12. Operate the hand
priming lever on diaphragm type fuel transfer pump
until there are no air bubbles in fuel flowing from the
fuel return line fitting. Then connect the fuel return
line.

If the camshaft's pump lobe is up, crank engine one revolution to
permit hand priming. When finished, return priming lever inward
(disengaged position) to permit normal pump operation.
Radiator: See Specifications for water capacity.
Check to see that the radiator drain valve is closed
and cylinder block drain plug is tight. Fill the radiator
with clean, soft (alkali free) water such as rain water.
The use of a good rust and scale inhibitor is
recommended.
If the set will be exposed to freezing temperatures,
use a standard anti-freeze solution. Use the correct
proportion of anti-freeze as recommended by the
anti-freeze manufacturer, to protect to at least 10
o
F
below the lowest expected temperature.
AC Generator: Periodic inspections, that coincide
with engine oil changes will ensure good perfor-
mance.
STARTING
SEQUENCE
The starting and stopping (Figure 13) sequence
shows the manual, mechanical, and electrical events
required for satisfactory start, run, and stop cycles.
PRE-HEATING
AND
STARTING
Extremes in starting temperatures may require ad-
ditional preheating. If enginefailsto startquickly, rest
engine several seconds and repeat starting sequence
applying preheat for a longer interval using heater
switch.
If the set control has a reset button, push it to reset
only after a shutdown resulting from oil pressure
failure occurs. Find the cause before restarting the
engine.
To prevent false starts, hold on start switch until the centrifugal
switch automatically disengages starter motor.
