Engine Starting

Before Starting Engine
Perform the required daily maintenance and other
periodic maintenance before the engine is started.
Inspect the engine compartment. This inspection can
help prevent major repairs at a later date. Refer to
the Operation and Maintenance Manual,
"Maintenance Interval Schedule" for more
information.
• Ensure that the engine has an adequate fuel
supply.
• 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.
• Ensure that any driven equipment has been
disengaged. Minimize electrical loads or remove
any electrical loads.

Cables
(Do Not Use This Procedure in
Hazardous Locations that have
Explosive Atmospheres)
The connection of battery cables to a battery and
the disconnection of battery cables from a battery
may cause an explosion which may result in in-
jury or death. The connection and the disconnec-
tion of other electrical equipment may also cause
an explosion which may result in injury or death.
The procedures for the connection and the dis-
connection of battery cables and other electrical
equipment should only be performed in a nonex-
plosive atmosphere.
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 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.
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.
