SCRUBBING AND BRUSH INFORMATION
Pick up oversized debris before scrubbing. Pick
up pieces of wire, string, twine, etc., which could
become wrapped around the scrubbing brushes.
Plan the scrubbing in advance. Try to arrange
long runs with minimum stopping and starting. Do
an entire floor or section at one time.
Drive as straight a path as possible. Avoid
bumping into posts or scraping the sides of the
machine. Overlap the scrub paths by several
centimeters (a few inches).
Avoid turning the steering wheel too sharply when
the machine is in motion. The machine is very
responsive to the movement of the steering
wheel. Avoid sudden turns, except in
emergencies.
When scrubbing dead end aisles, start at the
closed end of the aisle and scrub your way out.
Adjust the machine speed, scrub brush pressure,
and solution flow as required when scrubbing.
Use minimum scrub brush pressure and solution
flow required for the best results. The machine
has an edge clean feature for scrubbing against
an edge.
If you see poor scrubbing performance, stop
scrubbing and refer to MACHINE
TROUBLESHOOTING .
For best results, use the correct brush type for
your cleaning application. The following are
recommended brush applications.
Non-scuff polypropylene scrub brush -- This
brush uses a softer, general purpose
polypropylene bristle to lift lightly compacted
soilage without scuffing high-gloss coated floors.
Nylon scrub brush -- Recommended for
scrubbing coated floors. Cleans without scuffing.
Super abrasive bristle scrub brush -- Nylon
fiber impregnated with abrasive grit to remove
stains and soilage. Strong action on any surface,
performing well on buildup, grease, or tire marks.
Stripping pad -- This brown pad is for stripping
floors. Quickly and easily cuts through old finish to
prepare the floor for re-coating.
