the rear bumper door / step in the lowered
position. Do not carry passengers on any part
of the machine.

OPERATION
16 T17 9020160 (5−2014)
HOW THE MACHINE WORKS
T17 With Cylindrical Brushes
T17 With Disk Brushes
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 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.

OPERATION
17
T17 9020160 (5−2014)
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 (Cylindrical and Disk)* −Softer
nylon bristles are recommended for scrubbing
coated floors. Cleans without scuffing.
Heavy Duty Polypropylene brush (Disk) −
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)−For stripping of floor
finish to prepare the floor for recoating.
Scrubbing pad (Blue) −For medium to
heavy−duty scrubbing. Removes dirt, spills, and
scuffs.
Buffing pad (Red) −For light duty scrubbing
without removing floor finish.
Polishing pad (White) −For maintaining highly
polished or burnished floors.
High productivity stripping pad (Black) −For
aggressive stripping of heavy finishes or sealers,
or 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) −For very
aggressive chemical free removal of floor finish to
prepare the floor for re−coating
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.

OPERATION
18 T17 9020160 (5−2014)
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.
Do not operate machine in areas where the
ambient temperature is above 43C (110F). Do
not operate scrubbing functions in areas where
the ambient temperature is below freezing 0C
(32F).
FOR SAFETY: When using machine, do not
scrub on ramp inclines that exceed 8.7%
grade or transport (GVWR) on ramp inclines
that exceed 12% grade.
