(1) Fuel Filter Cock
DEHYDRATE IN THE FUEL FILTER
1. Moistures and dusts included in fuel
are deposited in the filter. Please drain
the fuel filter by loosening its sensor
under the fuel filter.
2. Please tighten it out by hand after
drainage. (Not using tools)
3. Bleed the air by pushing down the prim-
ing pump by hand.
4. Bleed the air entirely, then lock the air
plug.
5. Start the engine, and checkfor oil
leakage.
IMPORTANT
When the air venting is finished,
fuel which does not contain air
bubbles will be filtered by the fuel
filter and sent to the fuel injec-
tion pump. Fill the fuel tank be-
fore it becomes empty. If a die-
sel system is allowed to run out
of fuel, it will become necessary
to eliminate air from the fuel sys-
tem after filling the fuel tank.
