HOW THE MACHINE WORKS
The steering wheel controls the direction of
machine travel. The directional pedal controls the
speed and forward/reverse direction. The brake
pedal slows and stops the machine.
The side brush sweeps debris into the path of the
main sweeping brush. The main brush sweeps
debris from the floor into the hopper. The vacuum
system pulls dust and air through the hopper and
the hopper dust filter.
Water and detergent from the solution tank flows
to the floor through a solution valve to the scrub
brushes. The brushes scrub the floor. As the
machine is moved forward the squeegee wipes
the dirty solution off the floor, which is then picked
up and drawn into the recovery tank.
When using the ES
mode, the dirty solution in
the recovery tank is filtered and returned to the
solution tank to be reused.
When sweeping and scrubbing is finished, clean
the hopper dust filter, empty the hopper, and drain
and clean the recovery tank. If using the ES
system, drain and clean the solution tank, and
clean the ES
filter.
PRE-OPERATION CHECKLIST
Check under the machine for leaks (fuel, oil,
coolant, scrubbing solution).
