OPERATION

HOW THE MACHINE WORKS
The 1−STEP button makes it possible to
immediately begin scrubbing by operating all the
scrubbing functions.
When in the conventional Scrub mode, a water
and detergent mixture is used to scrub the floor.
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.
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
scrubbing applications.
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.
BRUSH AND PAD INFORMATION
For best results, use the appropriate brush or pad
for the cleaning application. Listed below are
brushes and pads 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 brush or
pad to use. Contact a Tennant representative for
specific recommendations.
Nylon brush (Disk)* − Softer nylon bristles are
recommended for scrubbing coated floors. Cleans
without scuffing.
Polyester brush (Cylindrical) − Softer general
purpose polyester bristles gently clean while
scrubbing. Perfect for sensitive floor surfaces.
Polyester does not absorb water so it is preferred
over Nylon in wet applications.
PolyPro brush (Cylindrical) − 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 (Cylindrical and Disk)* −
General purpose polypropylene bristles lift lightly
compacted dirt without scuffing high-gloss coated
floors.
Super AB brush (Cylindrical and Disk)* −
Nylon fiber with an abrasive grit to remove stains
and compacted dirt. Aggressive action on any
surface. Performs well on buildup, grease, or tire
marks.
*This brush is also available for the side brush.
Stripping pad (Brown)− Quickly and easily cuts
through old finish to prepare the floor for
recoating.
Scrubbing pad (Blue) − Removes dirt, spills, and
scuffs. Leaves a clean surface ready for
recoating.
Buffing pad (Red) − Quickly cleans and removes
scuff marks while polishing the floor to a high
gloss.
Polishing pad (White) − Maintains a high gloss.
Use for buffing very soft finishes and lower traffic
areas, and polishing soft waxes on wood floors.

OPERATION
15
T16 9008142 (1−11)
High productivity pad (Black) − Aggressively
strips floor finishes/sealers. Use for very
heavy−duty scrubbing. This pad can only be used
with the grip pad driver, not the tufted pad driver.
Surface preparation pad (Maroon) −
Aggressively strips floors without use of
chemicals.
Grip pad driver − The grip−face backing allows
pads to be fully used and holds pads in place
without penetrating the pad. The spring−activated
centering device works with all Tennant pads and
allows for fast, easy pad replacement.
Tufted pad driver − Standard pad driver has
short bristles, or “tufts,” on the back to hold the
pad in place. This driver works with all Tennant
pads except the black high productivity pad.
WHILE OPERATING THE MACHINE
Pick up oversized debris before scrubbing. Pick
up wire, string, twine, large pieces of wood, or any
other debris that could become wrapped around
or tangled in the brushes.
Drive in a 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.
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 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 slowly
on inclines and slippery surfaces.
The maximum rated incline for scrubbing with the
machine is 4or 7%. The maximum rated incline
during transport of the machine is 8or 14%.

SCRUBBING (ec−H2O MODE)
FOR SAFETY: Before leaving or servicing
machine, stop on level surface and turn off
machine.
1. Open the solution tank cover.
2. Fill the solution tank with only clean COOL
WATER (less than 21°C / 70°F).DO NOT use
hot water or add any conventional floor
cleaning detergents or a FaST or ec−H2O
system failure may result. Fill the solution
tank with water until the level is approximately
50 mm (2 in) below the indicator tab.
WARNING: Flammable materials can
cause an explosion or fire. Do not use
flammable materials in tank(s).
NOTE: Do not use the FaST or ec−H2O system
when there are conventional cleaning detergents
in the solution tank. Drain, rinse, and refill the
