Parking Brake Circuit
Note:
The parking brake has a proximity switch
associated with the interlock system.
The switch contact point is activated through
the operation of the brake pedal, controlling
starting and stopping of the engine.
Warning
Be sure to stop the engine before adjusting
the proximity switch.
Park in a flat location and make sure to
chock the wheels so that the machine
does not move.
Depress the brake, engage the latch of the
parking brake lock lever into the second
notch, and apply the parking brake.

Turn the key switch to "ON."
Loosen the bolts.
Move and adjust the proximity switch
mounting board so that the relay
generates a sound when the proximity
switch magnet part comes to the position
of the sensing part.
If the sound is not generated even after
adjustment, inspect the individual relay
and proximity switch.
If there is no abnormality in the relay,
check the traveling pedal/neutral circuit.
Tighten the bolts.
