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 brush paths.
When scrubbing dead end aisles, start at the
closed end of the aisle and scrub your way out.
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. When approaching a corner, turn off the
solution flow before turning the corner. Turn on
the solution flow once the machine has completed
the turn.
When the recovery tank is full, the recovery tank
full indicator will stay lit, and the scrubbing
operations will shut off. 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 scrubbing application. The following are
recommendations for main scrubbing, and side
brush applications.
Polypropylene main scrub brush
-- A
general-purpose brush with stiff bristles for
aggressive action on slightly compacted soilage.
Works well on concrete, wood, and tile surfaces.
Nylon main scrub brush
-- Recommended for
scrubbing coated floors. Cleans without scuffing.
NOTE: Nylon scrub brushes require a different
hydraulic valve configuration.
Super abrasive bristle main 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.
