Air-Bleeding Fuel System
To bleed air from the fuel system:
・ Fill the fuel tank.
・
Turn the fuel cock to ON . (TG5330/5390)
・
Turn the main switch ’’ON’’ and turn the fuel cock to
’’AIR’’. (TG5470)
・
Loosen the air-bleeding screw of the fuel injection
pump and let air bubbles out of the pump.
FIG. 6-24: If the engine still fails to start, pressure injec-
tion line can be loosened where they attach to the injec-
tors. Turn the engine over several times, until fuel spouts
out, then tighten the lines and stop the engine.
NOTE: Normally, further air-bleeding is not required due
to electric fuel pump operating when main switch
in instrument panel is ON.
If engine will not start after several attempts, check
fuel pump fuses (see Electrical System ).
Fuel Tank Filler Cap
When fuel tank filler cap is removed, a hissing or popping
noise may be noticed. This is due to cap design and is a
normal condition. Do not alter cap or use unapproved
replacement as fuel leakage may occur in event of Tractor
upset.
Throttle Lever
FIG. 6-25: Hand throttle lever should remain in position
selected by operator. Through normal use, friction against
lever may decrease, causing lever to move out of selected
position. Turn adjusting nut, 1, as required to retain throt-
tle lever in position selected.
NOTE: Throttle lever friction adjustment is accessed by
removing rear steering column cover.
