HOW THE MACHINE WORKS
The steering wheel controls the direction of
machine travel. The directional pedal controls the
speed and forward/reverse directions. The brake
pedal slows and stops the machine.
The scrub components of the machine are a
solution tank, scrub brushes, rear and side
squeegees, a vacuum system, and a recovery
tank.
Water and detergent, from the solution tank, flow
to the floor through a solution valve to the scrub
brushes. The brushes scrub the floor. As the
machine is moved forward the squeegees wipe
the dirty solution off the floor, which is then picked
up and drawn into the recovery tank.
When using the ES
t
mode, the solution in the
recovery tank is filtered and returned to the
solution tank to be reused.
Two different widths of scrub heads are available
for the machine. The MaxPro
t
1000 scrub head
contains two disk scrub brushes. The MaxPro
t
1200 scrub head contains three disk scrub
brushes.
When finished scrubbing, drain and clean the
recovery tank. If using the ES
t
system, drain and
clean the solution tank, and clean the ES
t
filter.
