SWEEPING, SCRUBBING, AND BRUSH
INFORMATION
Pick up oversized debris before sweeping. Flatten
or remove bulky cartons from aisles before
sweeping. Pick up pieces of wire, twine, string,
etc., which could become entangled in brush or
brush plugs.
Plan the sweeping and scrubbing in advance. Try
to arrange long runs with minimum stopping and
starting. Sweep debris from very narrow aisles
into main aisles ahead of time. 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 brush paths.
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.
Adjust the machine speed, scrub brush pressure,
and detergent and solution flow as required when
scrubbing. Use minimum scrub brush pressure
and solution flow required for the best scrubbing
results. The machine has an edge clean feature
for scrubbing against an edge.
When the recovery tank is almost full, the
recovery tank full indicator will light. The recovery
tank will have to be drained and cleaned. Then
refill the solution tank with clean water and
detergent and continue cleaning.
For best results, use the correct brush type for
your sweeping and scrubbing application. The
following are recommendations for main
sweeping, scrubbing, and side brush applications.
Nylon 5-double and 8-double Row Main Brush
– Recommended for general sweeping, and has
good hopper loading. Nylon has the longest life of
the bristle types. Use this brush for sweeping
rough or irregular surfaces.
Nylon 24-row Main Brush – Recommended for
severe dust conditions on rough surfaces. This
brush has excellent pickup and long life.
Polypropylene 8-double Row Main Brush –
Superior pick-up of sand, gravel, and paper litter.
Polypropylene retains its stiffness when wet, and
can be used indoors or out with equal
performance. Not recommended for
high-temperature debris.
