FUEL SYSTEM
AIR
BLEEDING
If
fuel
is
exhausted and the engine stops or when the fuel
filter element
is
cleaned, air
is
induced into the fuel line.
In
such case, the fuel system must
be
bled after refilling
the fuel
tank.
If
air remains
in
the
fuel line,
the
engine can-
not
be
started_
FUEL FILTER AIR BLEEDING
Fill
the fuel
tank
up
to
proper leveL Loosen No.1 air vent
screw
sh
own
in
the above
photo
and tighten it up after
filling with fuel until no air
is
noticed. Then loosen
No.2
air vent screw,
fill
with fuel until no air
is
noticed and
tighten up
the
air vent screw
in
the
same manner.

the
fuel, tighten the screw.
NOTE
With this operation, the engine should start, but
if
not,
bleed the injection pipe.
FUEL PIPE AIR BLEEDING
Loosen the
nut
of
the injection nozzle
as
shown above and
shift the throttle lever
to
high speed position. Then, start
the engine
by
operating the starter
motor
and make sure
the
fuel
is
discharged properly at
the
loosened nozzle
connection. Tighten the
nut
to
the specified
torque.
Start
the engine according
to
the steps given
in
"OPE RAT-
ING
THE TRACTOR".
NOTE
Unless air
is
completely bled, the engine can
not
be
started;
in
such case, perform air bleeding again
to
let
remaining air completely
out
of the system.
