TO BEGIN THE CLEANING OPERATION

5. Move solution control lever to the desired setting.
6. Turn on the ESP Recycling system switch, if applicable.
7. Begin scrubbing operation.
Single scrub the average floor with light to medium soil. In this operation the cleaning is accomplished in one pass,
with simultaneous solution feed, sweeping, scrubbing and dirty water pick up. The rate of solution feed and the
speed of travel required will vary with floor condition. This knowledge will come with operator experience.
TO STOP THE CLEANING OPERATION
Discontinue the cleaning operation whenever a low level or Tank 1 high level warning or stop light is illuminated.
The low level light will illuminate when the solution tanks are empty. At this time, discontinue the scrubbing cycle,
put all controls in position for transport and drive to the drain area. See pages 30-32 for instructions on how to drain
and clean the tanks.
The Tank 3 high level warning light will illuminate approximately 5 minutes before loss of vacuum to the tank. This
warning period should give ample time to complete the scrubbing cycle and transport or scrub to the drain area.
