b. Add the correct grade of fuel to the fuel tank,
and attempt to restart the engine. If the engine
will not start, go to Step 2.
NOTE: If the fuel system was completely empty,
contact Unit Maintenance to prime the fuel system
before attempting to start the engine.
c. Check the grade of fuel which was last added to
the tank. If the fuel grade is not correct for the
current operating environment, refer the problem
to Unit Maintenance. If the fuel grade is correct
for the current operating environment, go to
Step 2.
2. Circuit breakers tripped:
Reset the following circuit breakers: main,
alternator, engine control, and transmission control.
Refer to “Monitoring Systems and Cab Features,
Circuit Breakers” and “Machine Features, Main
Circuit Breakers” in this section. Attempt to start
the engine again. If the engine will not start, go to
Step 3.
3. Water in fuel:
a. Check the water separator in the primary fuel
filter for water or sediment. If water or sediment
is not present, go to Step c. 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
according to local regulations. Attempt to start
the engine. If the engine does not start, go to
Step c.
c. Refer the problem to Unit Maintenance for
repair.
Problem 10: Engine Power Less Than Normal
Probable Cause(s)
• Restriction in air intake system
• Poor quality or wrong grade of fuel for operating
conditions
1. Restriction in air intake system:
a. Check the air filter indicator. If red does not
appear in the window, go to Step 2. If red
appears in the window, go to Step b.
b. Clean the primary air filter element, and operate
the machine. If the engine power is still below
normal, go to Step 2.
2. Poor quality or wrong grade of fuel for operating
conditions:
a. Check the grade of fuel which was last added to
the tank. If the fuel grade is not correct for the
current operating environment or the fuel quality
is poor, go to Step b. If the fuel grade is correct
for the current operating environment, go to
Step c.
b. Report the fuel grade or quality problem to Unit
Maintenance.
c. Report the low power problem to Unit
Maintenance for evaluation.
Problem 11: Transmission Will Not Go in Any
Gear
Probable Cause(s):
• Parking brake is engaged
• Low power train oil pressure
1. Parking brake is engaged:
a. Release the parking brake and go to Step b.
Refer to “Problem 14: Parking Brake Will Not
Release” in this manual.
b. With the service brake depressed, move the
transmission control lever to the desired gear. If
the transmission does not go into gear, go to
Step 2.
2. Low power train oil pressure:
a. Check the power train oil level. If the power train
oil level is low, go to Step b. If the power train oil
level is normal, go to Step d.
b. Check for visible leaks in the power train
hydraulic system. If leaks are found, go to Step
d. If no leaks are found, go to Step c.
c. Add the appropriate amount and grade of oil to
the power train hydraulic system, and attempt to
move the machine again. If the machine does
not move, go to Step d.
d. Refer the problem to Unit Maintenance for
repair.
