4.
Turn the key in the ignition switch to the ON
position. The electric fuel pump will begin
operation, forcing air out around air bleed screw.
Leave the key in the ON position until a solid
stream of fuel flows out around the screw.
Tighten the screw and turn the key to OFF.
Note: Normally, the engine should start after
these bleeding procedures. However, if it
doesn't, air may be trapped between the injection
pump and the injectors; refer to Bleeding Air
from the Injectors, page 31
Checking the Interlock System
The purpose of the safety interlock system is to
prevent the engine from cranking or starting unless the
traction pedal is in neutral and the power take-off
switch is in the OFF position. Also, the engine will
stop when the power take-off control is engaged or the
traction pedal is depressed with operator off the seat
or when the parking brake is engaged.
CAUTION
If the safety interlock switches are disconnected or
damaged, the machine could operate unexpectedly
and cause personal injury.
•
Do not tamper with the interlock switches.
•
Check the operation of the interlock switches
daily and replace any damaged switches before
operating the machine.
•
Replace switches every two years, regardless of
whether they are operating properly.
1.
Move the power take-off switch to the OFF
position and remove your foot from the traction
pedal.
2.
Turn the ignition key to START. The engine
should crank. If the engine cranks, go to step 3.
If the engine does not crank, there may be a
malfunction in the interlock system.
3.
Rise off the seat and engage the power take-off
switch while the engine is running. The engine
should stop within 2 seconds. If the engine stops,
the switch is operating correctly; go to step 4. If
the engine does not stop, there is a malfunction in
the interlock system.
4.
Rise off the seat and depress the traction pedal
while the engine is running the power take-off
lever is disengaged. The engine should stop
within 2 seconds. If the engine stops, the switch
is operating correctly; go to step 5. If the engine
does not stop, there is a malfunction in the
interlock system.
5.
Engage the parking brake. Depress the traction
pedal while the engine is running and the power
take-off lever is disengaged. The engine should
stop within 2 seconds. If the engine stops, the
switch is operating correctly; continue operation.
If the engine does not stop, there is a malfunction
in the interlock system.
