Running out of fuel
Avoid running out of fuel as this will allow air to enter the fuel system,
which will make restarting the vehicle difficult.
If you have run out of fuel:
•
If your vehicle is equipped with dual fuel tanks,
add at least
15–19 liters (4–5 gallons) of fuel to each tank before attempting to
restart the engine.
•
If your vehicle is equipped with the Caterpillar 3126 B engine,
the fuel system must be primed before attempting to restart the
engine. Refer to the engine operator’s manual for instructions on
priming the engine.
•
Use caution not to overheat and damage the starter
by cranking
the engine for an excessive period of time. You may need to crank the
engine for a longer time than normal. If the engine fails to start in 30
seconds, turn the ignition to the OFF position and wait for two
minutes before cranking the engine again.
•
Any remaining trapped air will self-purge from the fuel system once
the engine starts running.
•
The engine may run rough and produce white smoke while air is in
the fuel system. This is normal and should stop after a short period of
time.
Fuel filter/water separator
Do not drain water separator while engine is running. Fuel may
ignite if separator is drained while engine is running or vehicle is
moving.
The fuel filter/water separator removes any contaminated particles
and/or water from the fuel before the fuel enters the engine.
The fuel filter/water separator should be drained as recommended in the
Scheduled Maintenance Guide.
