−18 °C (0 °F) from the use of a jacket water heater
or extra battery capacity.
When Group 2 diesel fuel is used, the following items
provide a means of minimizing starting problems
and fuel prob
lems in cold weather: Engine oil pan
heaters, jacket water heaters, fuel heaters, and fuel
line insulation.
Use the procedure that follows for cold weather
starting.
Note: Do not adjust the engine speed control during
start-up. The electronic control module (ECM) will
control th
e engine speed during start-up.
1. Disengage any driven equipment.
2. Turn the keyswitch to the RUN position. Leave the
keyswitch in the RUN position until the warning
light for
the glow plugs is extinguished.
NOTICE
Do not engage the starting motor when flywheel is
turning
. Do not start the engine under load.
If the engine fails to start within 30 seconds, release
the star
ter switch or button and wait two minutes to
allow the starting motor to cool before attempting to
start the engine again.
3. When the warning light for the glow plugs is
extinguished turn the keyswitch to th e START
posit
ion in order to engage the electric starting
motor and crank the engine.
Note
: The operating period of the warning light for
the glow plugs will change due to the temperature
of the engine.
4. Allow the keyswitch to return to the RUN position
after the engine starts.
5. Repeat step 2 through step 4 if the engine fails
to start.
Note: The engine should not be “raced” in order to
speed up the warm up process.
6. Allow the engine to idle for three to five minutes, or
allow the engine to idle until the water temperature
in
dicator begins to rise. When idling after the
engine has started in cold weather, increase the
engine rpm from 1000 to 1200 rpm. This will
wa
rm up the engine more quickly. Maintaining
an elevated low idle speed for extended periods
will be easier with the installation of a hand
t
hrottle. Allow the white smoke to disperse before
proceeding with normal operation.
7. Operate the eng
ine at low load until all systems
reach operating temperature. Check the gauges
during the warm-up period.

Starting w ith Jump Start
Cables
Improper jump start cable connections can cause
an explosi
on resulting in personal injury.
Prevent sparks near the batteries. Sparks could
cause vap
ors to explode. Do not allow jump start
cable ends to contact each other or the engine.
Note: If
it is possible, first diagnose the reason for
the starting failure. Refer to Troubleshooting, “Engine
Will Not Crank and Engine Cranks But Will Not Start”
for furt
her information. Make any necessary repairs.
If the engine will not start only due to the condition
of the battery, either charge the battery, or start the
engine
by using another battery with jump start
cables.
The condition of the battery can be rechecked after
the eng
inehasbeenswitchedOFF.
NOTICE
Using a battery source with the same voltage as the
electric starting motor. Use ONLY equal voltage for
jump starting. The use of higher voltage will damage
the electrical system.
Do not reverse the battery cables. The alternator can
be damaged. Attach ground cable last and remove
first.
Turn all electrical accessories OFF before attaching
the jump start cables.
Ensure that the main power switch is in the OFF posi-
tion before attaching the jump start cables to the en-
gine being started.
1. Turn the start switch on the stalled engine to the
OFF position. Turn off all the engine's accessories.
2. Connect one positive end of the jump start cable
to the positive cable terminal of the discharged
battery. Connect the other positive end of the jump
start cable to the positive cable terminal of the
electrical source.
