a. Check the air filter indicator. If red does not
appear in the window, go to Step 6. If red
appears in the window, go to Step b.
b. Clean the primary air filter element, and attempt
to restart the engine. If the engine does not
restart, go to Step 6.
6. Cold ambient temperatures:
Do not operate the engine coolant heater in an
enclosed area. The heater produces combustion
gasses which may be harmful. Always start and
operate the heater in a well ventilated area.
a. If the temperature is above approximately 5°C
(40°F), go to Step 7. If the temperature is
between -32°C and approximately 6°C (-25°F
and 40°F), go to Step b. If the temperature is
below -32°C (-25°F), go to Step e.
b. Observe the start-aid indicator after moving the
start switch from OFF to ON. If the start-aid
indicator illuminates for approximately 30
seconds, go to Step d. If the start-aid indicator
does not illuminate, go to Step c.
c. Reset the start-aid circuit breaker and the intake
air heater circuit breaker. Observe the start-aid
indicator when the start switch is moved from
OFF to ON. If the start-aid indicator does not
illuminate, go to Step 7. If the start-aid indicator
illuminates, go to Step d.
d. Hold start-aid switch in the ON position for three
seconds, and attempt to start the engine. If the
engine does not start go to Step 7.
e. Turn the engine coolant heater ON. If the
indicator in the engine coolant heater switch
illuminates, go to Step g. If the indicator does
not illuminate, go to Step f.
f. Reset the engine coolant heater circuit breaker,
and turn the engine coolant heater ON. If the
indicator in the engine coolant heater switch
illuminates, go to Step g. If the indicator does not
illuminate, refer the problem to Unit Maintenance
for repair.
g. Allow the engine coolant heater to operate for
40 minutes. After a three-minute cool down
period, attempt to start the engine. If the engine
does not start, go to Step 7.
7. Batteries not providing sufficient voltage:
Follow the procedure given in Problem 1, Step 4.
Problem 3: Engine Runs Roughly After Starting
Probable Cause(s):
• Cold ambient temperatures
• Water in fuel
• Restriction in air intake system
1. Cold ambient temperatures:
Refer to the engine starting procedure for the
appropriate air temperature, and follow the steps in
the procedure to start the machine and warm it up.
If the machine does not run smoothly after 10
minutes, go to Step 2.
2. Water in fuel:
Diesel fuel is combustible. Do not smoke when
working around diesel fuel. Open flames or
sparks can cause a fire or explosion.
a. Check the water separator in the primary fuel
filter for water or sediment. If water or sediment
is not present, go to Step 3. If water or sediment
is present, go to Step b.
b. Drain the water and sediment from the water
separator into a container, and discard the fluid
in accordance with local regulations. Operate
the engine for several minutes. If the engine
does not run smoothly after several minutes of
operation, go to Step 3.
3. Restriction in air intake system:
a. Check the air filter indicator. If red does not
appear in the window, refer the problem to Unit
Maintenance for repair. If red appears in the
window, go to Step b.
b. Clean the primary air filter element, and check
the engine operation. If the engine does not run
smoothly, refer the problem to Unit Maintenance
for repair.
