4. Batteries not providing voltage:
Batteries produce flammable gasses. Do not
smoke when working around batteries. Open
flames or sparks can cause an explosion.
Remove jewelry and dog tags when working with
batteries. Metal shorting across battery poles can
cause electrical shock.
Batteries contain a strong acid solution. Wear
protective gloves and safety glasses or goggles
when working around batteries.
a. With the start switch in the ON position, observe
the position of the needle in the voltmeter. If the
needle lies within the first green zone, go to Step
b. If the needle in the voltmeter points to the first
red zone, go to Step c.
b. The batteries are fully charged. Refer the
problem to Unit Maintenance for repair.
c. Inspect the battery for damage, or loose or
corroded connections. Clean and apply grease
to the battery terminals and terminal clamps.
Tighten terminal clamps to the battery terminal
clamps. Proceed to Step d.
d. Attempt to start the engine again. If the engine
does not crank, refer the problem to Unit
Maintenance for repair.
Problem 2: Engine Cranks but Will Not Start
Probable Cause(s):
• No fuel or incorrect fuel
• Engine in crank-without-inject mode
• Needle valve open
• Engine oil level low
• Restriction in air intake system
• Cold ambient temperatures
• Batteries not providing sufficient voltage
1. No fuel or incorrect fuel:
Diesel fuel is combustible. Do not smoke when
working around diesel fuel. Open flames or
sparks can cause a fire or explosion.
a. With the start switch in the ON position, observe
the position of the needle in the fuel gauge. If the
needle is above the empty mark and there is fuel
visible in the tank, go to Step c. If the needle is
on the empty mark, go to Step b.
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 is completely empty, contact
Unit Maintenance to prime the fuel system before
attempting to start the engine.
c. Refer the problem to Unit Maintenance for
repair.
2. Engine in crank-without-inject mode:
a. With the start switch in the ON position and the
blackout light switch in STOP LIGHT, observe
the crank-without-inject indicator. If the indicator
is not illuminated, go to Step 3. If the indicator is
illuminated, go to Step b.
b. Refer the problem to Unit Maintenance for
repair.
3. Needle valve open:
Ensure that the needle valve on the remote
hydraulic tool manifold is closed. Refer to
“Maintenance Features, Remote Hydraulic Tool
Ports” in this section. If the needle valve is open,
close the valve, and attempt to start the engine. If
the needle valve is closed, go to Step 4.
4. Engine oil level low:
a. Check the engine oil level. If the engine oil level
is normal, go to Step 5. If the engine oil level is
low, go to Step b.
b. Fill the crankcase with the appropriate type of
engine oil, and attempt to start the engine again.
If the engine does not start, go to Step 5.
5. Restriction in air intake system:
