Air-Bleeding Fuel System
If any of the following conditions have occurred, system
should be bled:
Fuel tank has been permitted to run dry.
Fuel lines, filter element(s) and other components within
system have been disconnected or removed.
If engine has not been operated for a considerable period
of time.
If engine fails to start, or if it starts but stops again after a
few minutes of operation.
FIG. 73: Make sure fuel tank is full to provide gravity flow
of fuel to filter. Turn valve, 2, on fuel filter to
AIR position (handle to front).
Allow air bubbles and fuel to drain from overflow pipe, 3,
until air bubbles disappear and only fuel drains out.
Turn valve, 2, to ON position (handle down).

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, ch-
eck 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. 74: Hand throttle lever should remain in position
selected by operator. Through normal use, friction against
lever may decrease, causing lever to move out of select-
ed position. Turn adjusting nut, 1, as required to retain
throttle lever in position selected.
NOTE: Throttle lever friction adjustment is reached by re-
moving the steering column cover, and instrument
panel.
