required
daily
maintenance
and
any

•
Open the fuel supply valve (if equipped).
NOTICE
All valves in the fuel return line must be open before
and during engine operation to help prevent high fuel
pressure. High fuel pressure may cause filter housing
failure or other damage.
If the engine has not been started for several weeks,
fuel may have drained from the fuel system. Air may
have entered the filter housing. Also, when fuel filters
have been changed, some air pockets will be trapped
in the engine. In these instances, prime the fuel
system. Refer to the Operation and Maintenance
Manual, “Fuel System - Prime” for more information
on priming the fuel system.
Engine exhaust contains products of combustion
which may be harmful to your health. Always
start and operate the engine in a well ventilated
area and, if in an enclosed area, vent the exhaust
to the outside.
• Do not start the engine or move any of the controls
if there is a
“
DO NOT OPERATE
”
warning tag or
similar warning tag attached to the start switch or
to the controls.
• Reset all of the shutoffs or alarm components (if
equipped).
• Ensure that any equipment that is driven by the
engine has been disengaged from the engine.
Minimize electrical loads or remove any electrical
loads.

Starting the Engine
1.
Disengage any equipment that is driven by the
engine.
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.
3.
When the warning light for the glow plugs is
extinguished turn the keyswitch to the START
position 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.
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 starter switch or button and wait two minutes to
allow the starting motor to cool before attempting to
start the engine again.
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.

Starting
with
Jump
Start
Cables
Improper jump start cable connections can cause
an explosion resulting in personal injury.
Prevent sparks near the batteries. Sparks could
cause vapors 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 further 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 engine has been switched OFF.
