CIRCUIT BREAKERS AND FUSES
CIRCUIT BREAKERS
Circuit breakers are resettable electrical circuit
protection devices that stop the flow of current
in the event of a circuit overload. Once a circuit
breaker is tripped, allow breaker to cool and
then press the reset button to manually reset the
breaker.
If the overload that caused the circuit breaker to
trip is still there, the circuit breaker will continue to
stop current flow until the problem is corrected.
The circuit breakers are located inside the battery
compartment next to the hour meter.
The chart shows the circuit breakers and the
electrical components they protect.

FUSES
The fuse is a one-time protection device designed
to stop the flow of current in the event of a circuit
overload. The 100 A fuse is located in the seat
support column near the scrub head actuator. The
fuse protects the machine controller.
NOTE: Always replace the fuse with a fuse of the
same amperage.
ELECTRIC MOTORS
FOR SAFETY: Before leaving or servicing
machine, stop on level surface, turn off
machine, and remove key.
The carbon brushes in the vacuum fan motor,
the propelling motor, and the scrub brush motors
should be inspected after the initial 500 hours of
machine operation and then every 100 hours after
the initial 500 hours.
