HOW THE MACHINE WORKS
This machine can effectively scrub or sweep dirty
floors. The 1−STEP Scrub button and 1−STEP
Sweep button make it possible to immediately
begin scrubbing or sweeping.
The 1−STEP Sweep button operates all the dry
sweeping functions (without scrubbing). The
1−STEP Scrub button operates all the scrubbing
functions. (The machine also sweeps while
scrubbing).
When in the conventional Scrub mode, a water
and detergent mixture is used to scrub the floor.
When in the optional FaST (Foam scrubbing)
mode, the FaST scrubbing system mixes the
FaST−PAK concentrate with a small amount of
water, creating a large volume of expanded wet
foam. The FaST system can be used with all
double scrubbing and heavy duty scrubbing
applications.
When in the optional ES (Extended Scrub) mode,
the dirty solution in the recovery tank is filtered
through the ES system and returned to the
solution tank for reuse. Detergent is then injected
into the returned solution to revitalize the cleaning
capability of the solution.
BRUSH INFORMATION
For best results, use the correct brush type for the
cleaning application. Listed below are the brushes
and the applications for which each is best suited.
NOTE: The amount and type of soilage play an
important role in determining the type of brushes
to use. Contact a Tennant representative for
specific recommendations.
PolyPro brush − Heavy duty polypropylene
bristles provide a more aggressive cleaning
performance and can more easily lift compacted
dirt, debris, and sand while offering excellent
scrubbing performance.
Polypropylene brush − General purpose
polypropylene bristles lift lightly compacted dirt
without scuffing high-gloss coated floors.
Polyester brush − Softer general purpose
polyester bristles lift light debris while sweeping
and gently clean while scrubbing. Perfect for
sensitive floor surfaces. Polyester does not
absorb water so it is preferred over Nylon in wet
applications.
Super AB brush − Nylon fiber impregnated with
abrasive grit to remove stains and compacted dirt.
Aggressive action on any surface. Performs well
on buildup, grease, or tire marks.
When in the optional ec−H2O (electrically
converted water) mode, normal water passes
through a module where it is oxygenated and
charged with an electric current. The electrically
converted water changes into a blended acidic
and alkaline solution forming a neutral pH cleaner.
The converted water attacks the dirt, breaks it into
smaller particles, and pulls it off the floor surface
allowing the machine to easily scrub away the
suspended soil. The converted water then returns
to normal water in the recovery tank . The
ec−H2O system can be used with all double
scrubbing and heavy duty scrubbing applications.

WHILE OPERATING THE MACHINE
Home
Find...
Go To..
Pick up oversized debris before scrubbing or
sweeping. Pick up wire, string, twine, large pieces
of wood, or any other debris that could become
wrapped around or tangled in the brushes.
Drive as straight a path as possible. Avoid
bumping into posts or scraping the sides of the
machine. Overlap the scrub/sweep 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.
Adjust the machine speed, brush pressure, and
solution flow as required when scrubbing. Use the
lowest brush pressure and solution flow settings
for best performance. If the machine is equipped
with the FaST or ec−H2O system, use the FaST
or ec−H2O system for the best scrubbing results.
OPERATION
Keep the machine moving to prevent damaging
floor finishes.
If poor cleaning performance is observed, stop
cleaning and refer to MACHINE
TROUBLESHOOTING in this manual.
Perform the Daily Maintenance Procedures after
each use (see MACHINE MAINTENANCE in this
manual).
Drive the machine slowly on inclines. Use the
brake pedal to control machine speed on
descending inclines. Scrub with the machine up
inclines rather than down inclines.
FOR SAFETY: When using machine, go slow
on inclines and slippery surfaces.
The maximum rated incline for scrubbing with the
machine is 6 or 11%. The maximum rated incline
during transport of the machine is 8 or 14%.
