Cold Weather Starting.
CAUTION
Avoid overloading the air intake manifold with highly volatile starting fluid while attempting to
start the engine using the COLD START button (6, Figure 5-1). Do not attempt more that
three consecutive cold weather starts without first allowing the starting fluid in the air intake
manifold to dissipate. Failure to follow this caution could result in overloading the air intake
manifold with starting fluid which could result in a minor explosion and damage to the engine.
NOTE
The correct grade of oil for the prevailing temperature should be used in the crankcase to
prevent hard cranking.
NOTE
Diesel fuel should have a pour point of 10 (-12 ) less than the lowest expected
F
C
temperature. In case of emergency, white kerosene may be added to the fuel to bring the
pour point down to the required temperature to prevent clogging of filters and small passages
by wax crystals. The addition of kerosene is NOT recommended for general use. If low
temperatures are ONLY expected at startup, it is advisable to use starting aids such as
preheating, starting fluid metering equipment, or starting fluid spray application into the air
cleaner intake.
a. To start the engine, place the IGNITION switch (28, Figure 5-1) to the START position and push the COLD
START button (6) for two seconds and release.
b. If the engine does not start within 30 seconds, allow the starter to cool for approximately two minutes and
repeat the procedure.
5-3.3
Shutdown Procedure.
a. Allow the engine to operate at fast idle speed for approximately five minutes to avoid high internal heat
rise and allow for heat dissipation.
