1.
The fuel system can be primed from the keyswitch
or from a remote mounted switch (2).
2.
Turn the fuel priming switch (2) to the ON position.
Hold the fuel priming switch in the ON position for
2 minutes. If the fuel system is being primed from
empty, then turn the switch off and then on again
for 2 minutes.
3.
After 2 minutes the fuel system should be primed
and the engine ready to start.
4.
Start the engine, refer to this Operation and
Maintenance Manual, Starting the Engine or refer
to the OEM for instructions on starting the engine.
5.
If the engine starts and the engine runs rough or
the engine misfires, operate at low idle until the
engine is running smoothly. If the engine cannot
be started, or if the engine continues to misfire or
smoke, repeat Step 2.
The fuel system can also be primed by using the key
switch. Turn the key to the ON position for 2 minutes.
After 2 minutes the fuel system should be primed. If
necessary, by cycling the key switch the system will
prime again for 2 minutes.

Fuel leaked or spilled onto hot surfaces or electri-
cal components can cause a fire. To help prevent
possible injury, turn the start switch off when
changing fuel filters or water separator elements.
Clean up fuel spills immediately.
NOTICE
Do not allow dirt to enter the fuel system. Thoroughly
clean the area around a fuel system component that
will be disconnected. Fit a suitable cover over any
disconnected fuel system components.
NOTICE
Do not fill fuel filters with fuel before installing
them. The fuel will not be filtered and could be
contaminated. Contaminated fuel will cause ac-
celerated wear to fuel system parts. The fuel sys-
tem should be primed prior to starting the engine.
Water in the fuel can cause the engine to run rough.
Water in the fuel may cause an electronic unit injector
to fail. If the fuel has been contaminated with water,
the element should be changed before the regularly
scheduled interval.
The primary filter/water separator also provides
filtration to help extend the life of the secondary fuel
filter. The element should be changed regularly. If a
vacuum gauge is installed, the primary filter/water
separator should be changed at 50 kPa to 70 kPa
(7.25 psi to 10.15 psi).
