perators, a few specks of dirt and a dash
of water might seem harmless. But they are
deadly when it comes to the fuel system on
your Cat equipment.
Dirt clogs the fuel strainer or the filter.
Water can rust out the tank and damage the
engine’s injectors.
Keep your fuel supply clean by keeping it
covered and protected:
Drain water and sediment from the fuel
tank before you start up.
Before you refuel, wipe away any dirt
around the filler cap.
Be careful when you put the fuel nozzle
in the tank. You could tear a hole in the side
of the strainer or knock out its bottom.
Make sure the fuel tank strainer
is in place and in good shape. If
it’s damaged or missing, replace
it.

Good fuel PM will keep dirt and
moisture where they belong—outside.
Make sure the mechanic primes the
system after he changes the element,
too. Otherwise, you may not be able
to start your dozer.
Catch the fuel you drain in a clear
container. Drain until you get clean
fuel free of water. Dispose of this
drained fuel properly. If draining doesn’t
help, get the filter elements replaced.

you need a
fill up
.
When it’s raining or dust is blowing,
lay a clean rag around the nozzle while
you refuel.
When refueling’s done, replace the
cap and snug it down to keep dirt out
during operations.
Fill the fuel tank at the end of opera-
tions to help prevent condensation in
the tank.
When you start up, check the fuel
pressure gauge on the final filter. If the
gauge is reading out of the normal range,
shut down and drain the filters. If the
gauge isn’t working, get it replaced.
