3. Pump the fuel pump knob(1) located on the top of the
fuel filter. The fuel pump knob will pump easily at first
and with added resistance as air is purged from the
system. To make sure air is completely purged, pinch
the fuel overflow hose with fingers, if a pulsation is felt
when the knob is pumped, then, no air remains.
4. Set the hand throttle lever at the maximum speed
position, turn the key switch to start the engine, and
then reset the throttle lever at the mid speed (around
1500 rpm) position.
If engine doesn't start, try it several times at 30 second
intervals.
A
Do not hold key switch at engine start position for more
than 10 seconds continuously. If more engine cranking
is needed, try again after 30 seconds.
5. Accelerate the engine to remove the small portion of
air left in the fuel system.
6. If air still remains and the engine stops, repeat the
above steps.
7. Close the air vent cock.
A
Always close the air vent cock except for bleeding fuel
lines. Otherwise, engine runs irregularly or stalls
frequently.
B Replacing Fuse
The tractor electrical system is protected from potential
damage by fuses.
A blown fuse indicates that there is an overload or short
somewhere in the electrical system.
If any of the fuses should blow, replace with a new one of
the same capacity.
A
Before replacing a blown fuse, determine why the fuse
blew and make any necessary repairs. Failure to
follow this procedure may result in serious damage to
the tractor electrical system. Refer to the
"TROUBLESHOOTING" section of this manual or your
local KUBOTA Dealer for specific information dealing
with electrical problems. (1) Air vent cock (A) "CLOSE"
