CIRCUIT BREAKERS
The machine is equipped with (4) circuit breakers to
protect machine from damage.
If circuit breakers should trip, the breakers will not
reset immediately upon tripping. Determine reason
why breaker tripped, allow motor to cool and reset.
Brush motor circuit breakers will trip due to excessive
overload on pad. Reduce pad pressure or replace pad
if breaker should trip.
The main and drive/vacuum circuit breakers are
located at the rear of machine. The brush motor circuit
breakers are located near the charging plug
(Figure 19).
