The brush pressure gauge shows how hard the
scrub brush motors are working. The brush

Operating in the red zone indicates excessive
brush pressure, and will cause the scrub brush
circuit breakers to trip.
Adjust the brush pressure during scrubbing with
the scrub brushes switch.
SCRUB BRUSHES DOWN LIGHT
The scrub brushes down light comes on when the
scrub brushes are lowered enough to touch the
floor. The light goes off when the scrub brushes
are raised off the floor.
