TO SCRUB
Plan the scrubbing in advance. Try to arrange
long runs with minimum stopping and starting. Do
an entire floor or section at one time.
Pick up oversize debris before scrubbing.
Remove bulky debris from aisles before
scrubbing. Pick up pieces of wire, twine, string,
etc., which could become entangled in brush or
brush plugs.
Allow a few inches overlap of brush paths.
Try to scrub as straight a path as possible. Avoid
bumping into posts or scraping the sides of the
machine.
Floor conditions, amount of soilage, type of
soilage, brush action, and squeegee action all
play an important role in determining the type and
concentration of detergent to be used. For
specific recommendations, consult the local
Tennant Company Representative.
WARNING: Flammable Materials Can
Cause An Explosion Or Fire. Do Not
Use Flammable Materials In Tank(s).
The recovery tank should be drained after the
solution tank is empty and whenever the float
rises and stops water vacuum. The recovery tank
may fill before the solution tank empties if
standing water is picked up in addition to the
solution put down by the machine.
For best scrubbing results, reduce speed to
one-half maximum machine speed. Shut off
solution flow to floor 5 ft (1.5 m) before making
turns. Always raise the rear squeegee before
backing machine. Adjust solution flow to floor with
solution flow control lever to match floor
conditions.
