(1) Fuel Pipe (3) Fuel Filter Pot
(2) Air Vent Cock
AIR MUST BE ELIMINATED FROM THE FUEL
SYSTEM IN THE FOLLOWING CASES :
1. When the fuel filter and pipes are
removed.
2. When tank is completely empty.
3. After the tractor has not been used
for a long period of time.
CAUTION
Do not bleed the fuel system
when the engine is hot.
4. In order to eliminate air from the fuel
system, proceed as follows.
5. Fill the fuel tank with fuel and open the
fuel cock.
6. Open the air plug of the fuel filter, and
operate the priming pump, then lock it
after the air is bleeded completely.
7. When there are no more air bubbles in
the fuel line which flows out, tighten
as before.
ADJUSTING FAN BELT TENSION
(1) Bolt
(A) Check the belt tension
Proper
fan belt
tension
A deflection of between
7 ~ 9 mm (0.28 ~ 0.34 in.)
when the belt is pressed
in the middle of the span.
CAUTION
To avoid personal injury:
Be sure to stop the engine be-
fore checking belt tension.
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 injection pump. Fill the fuel tank
before it becomes empty. If a diesel sys-
tem is allowed to run out of fuel, it will
become necessary to eliminate air from
the fuel system after filling the fuel tank.
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.
