in figure 16. Pushing the scrub brush switch to up position will raise the scrub deck to the top position, the
scrub brushes will stop rotating, the water solenoid will de-energize and solution flow will stop. Pushing the
scrub brush switch down will lower the scrub deck to the set down pressure. The squeegee will lower and the
vacuum will activate. When the scrub brush and squeegee are on, they will be displayed as shown in figure 17.
The brushes will not rotate until the foot throttle is depressed. Releasing the foot throttle will raise the scrub
deck to the top position and the brushes will stop rotating.

SCRUB PRESSURE SWITCH

The scrub pressure switch is located on the left side of the console between scrub brush switch and the

OPERATING INSTRUCTIONS

• Scrub in straight paths. Do not bump posts. Do not scrape the sides of the machine.

Fig. 34

SCRUBBING PATH

• When the machine is in motion, do not push the directional/speed control pedal all the way forward.
This is the same as starting in “high” and will put a strain on the motor and drive system.

• Plan your sweeping and scrubbing in advance. Try to arrange long runs with minimum stopping and
starting. Sweep debris from narrow aisles out into main aisle ahead of time. Do an entire floor, or
section at on time.

• Pick up oversize debris before sweeping.

• Allow a few inches of overlap of sweep and scrub paths. This will eliminate leaving dirty patches.

• Allow a few inches of overlap of sweep and scrub paths. This will eliminate leaving dirty patches.

• Don’t turn steering wheel to sharply when machine is in motion. The machine is very responsive to

movement of the steering wheel; so avoid sudden turns.

• Try to follow as straight a path as possible. Avoid bumping into posts or scraping the sides of the
machine.

• When placing the machine in motion, avoid slamming the directional control pedal all the way
forward suddenly. This is equivalent to starting out in “HIGH” and puts needless strain on the drive
system. Periodically, turn the sweeping broom end for end to prevent the bristles from “settling” in
one direction.

TO STOP THE CLEANING OPERATION

Discontinue the cleaning operation when the low solution light or the high recovery light illuminates, this
indicates the solution tank is empty or recovery tank is full. Discontinue the scrubbing cycle, put all controls in
the forward position for transport and drive to the drain area.

NOTE

After stopping, perform these post operation checks.
