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 breaker will trip due to excessive

overload on pad. Reduce pad pressure or replace pad

if breaker should trip. Brush motor circuit breaker is

located near charger plug.

The main (15amp) and drive/vacuum (35amp) circuit

breakers are located at rear of machine (
