Before Starting Engine
Before the engine is started, perform the required
daily maintenance and any other periodic
maintenance that is due. Refer to the Operation
and Maintenance Manual, “Maintenance Interval
Schedule” for more information.
•
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
fi
lter 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
fi
lter housing. Also, when fuel
fi
lters 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.
•
Ensure that the coolant level is correct.
•
Ensure that the engine oil level is correct.

Cold Weather Starting
Do not use aerosol types of starting aids such as
ether. Such use could result in an explosion and
personal injury.
The engine will start at a temperature of
−
10 °C
(14 °F). The ability to start at temperatures below
10 °C (50 °F) will improve by the use of a cylinder
block coolant heater or a device which heats the
crankcase oil. This will help to reduce white smoke
and mis
fi
res when the engine is started in cold
weather.
If the engine has not been run for several weeks, fuel
may have drained. Air may have moved into the
fi
lter
housing. Also, when fuel
fi
lters have been changed,
some air will be left in the
fi
lter housing. Refer to
Operation and Maintenance Manual, “Fuel System -
Prime” in order to remove air from the fuel system.
Use the procedure that follows for cold weather
starting.
NOTICE
Do not engage the starting motor when
fl
ywheel 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 thirty seconds to
allow the starting motor to cool before attempting to
start the engine again.
1.
If equipped, press the start button. If equipped,
turn the keyswitch to the START position in order
to engage the electric starting motor and crank
the engine.
2.
Repeat step 1 three times if the engine fails to
start.
3.
If the engine fails to start, investigate the problem.
Use the Perkins electronic service tool. A system
fault may be indicated after the engine is started. If
this occurs the ECM has detected a problem with
the system. Investigate the cause of the problem.
Use the Perkins electronic service tool.
Note:
Oil pressure should rise within 15 seconds
after the engine starts. The electronic engine controls
monitor the oil pressure. The electronic controls will
stop the engine if the oil pressure is below normal.
