VENTlLATlON
Good ventilation is needed to cool the engine and to
support combustion.
Avoid
recirculation
of ventilat-
ing air.
lnhalafion
of
exhausf gases might
i
resulf in serious personal injury
or
death.
Do
not use exhaust heat to warm a
room,
compartment or storage area.

EXHAUST
Pipe exhaust gas outside any enclosure: exhaust gas
is poisonous. Exhaust pipes must not terminate near
inlet vents. Avoid sharp bends. Use sweeping, large-
radius elbows. Use a section of seamless, flexible
tubing between the engine and any rigid pipe to res-
trict vibration.

BATTERIES
Check the condition
of
the starting batteries at least
every two weeks. See that connections are clean and
tight.
A
light coating of non-conductive grease will
retard corrosion at terminals. Keep the electrolyte at
the proper level above the plates by adding distilled
water. Check specific gravity; recharge if below
1.260.
DUST AND DIRT
1.
Keep inlet screen free of dirt, etc.
2. Service air cleaner as frequently as necessary.
3.
Change crankcase oil every
50
operating hours.
4.
Keep oil and fuel in dust-tight containers.
5.
Keep governor linkage clean.
HIGH
ALTITUDE
Maximum power will be reduced approximately
4
percent for each
1000
feet (310 m) above sea level,
after the first 1000 feet (310
m).

LOW TEMPERATURES
Use correct SAE
No.
oil for temperature condi-
tions.
Change
oil
only when engine
is
warm. If an
unexpected temperature drop causes
an emer-
gency, move engine to a warm location or apply
heated air (never use open flame) externally until
oil
flows
freely.
Use fresh fuel. Protect against moisture conden-
sation.
.
Keep fuel system clean, and batteries in a well
charged condition.
Use additional preheat cycles during cold starts.
Do
not exceed one minute preheat
periods; longerperiods can
ruin
the
heater elements.
OPERATOR AND SERVICE MAINTENANCE SCHEDULE
NOTE
1.
Water or foreign material
in
fuel can
ruin
the injection
system.
If
daily inspection shows water
or
excessive
dirt
in
sediment bowl fuel, handling and storing facili-
ties should
be
checked and situation corrected. Prirn-
ary and secondary fuel filters must
be
replaced follow-
ing
correction of fuel contamination problem.
2.
Thisservice
must
beconducted by trained diesel injec-
tion equipment personnel with suitable test facilities.
Omit this service until these conditions can be met.
3.
Tighten head boltsand adjust valve clearanceafterfirst
50
hours on an overhauled engine.
