HOW THE MACHINE WORKS
T12 With Cylindrical Brushes
T12 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 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
18 T12 9009918 (3--2013)
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)-- 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) -- F o r
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) -- F o r v e r y
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

T12 9009918 (3--2013)
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).
The maximum rated incline for scrubbing with the
machine is 7%. The maximum rated incline during
transport of the machine is 14.1%.
PRE--OPERATION CHECKLIST
Perform the following steps before operating the
machine:
-Check the machine for fluid leaks.
-Check the operating lights.
-Check left side squeegee for wear and
damage.
-Check main brushes for wear and damage.
Remove wire, string, or twine wrapped around
the main scrub brushes.
-Machines equipped with cylindrical brushes:
Confirm the debris tray is empty and clean.
-Machines equipped with side brush option:
Check for wire, string, or twine wrapped
around the scrub brush.
-Machines equipped with side brush option:
Check squeegee for wear and damage.
-Check the rear squeegees for wear and
damage.
-Check the recovery tank cover seals for wear
or damage.
-Confirm the vacuum fan inlet filter is clean.
-Check the right side squeegee for wear and
damage.
-ec--H2O Scrubbing: Confirm all conventional
cleaning agents/restorers are drained and
rinsed from the solution tank.
-ec--H2O Scrubbing: Confirm the solution tank
is filled with clear cool water only.
-Check the brakes and steering for proper
operation.
-Check the tires for damage.
-Check maintenance records to determine
maintenance requirements.

FILLING THE SOLUTION TANK
ec-H2O SCRUBBING (ec-H2O MODE)
FOR SAFETY: Before leaving or servicing
machine, stop on level surface, turn off
machine, and remove key.
1. Remove the cap from the solution tank.
2. Fill the solution tank with only clean COOL
WATER (less than 21qC/70qF).DONOTuse
hot water or add any conventional floor
cleaning detergents or an ec--H2O system
failure may result. Fill the solution tank with
water until the level is approximately 50 mm
(2 in) below the cap.
WARNING: Flammable materials can
cause an explosion or fire. Do not use
flammable materials in tank(s).
NOTE: Do not use the ec--H2O system when
there are conventional cleaning detergents in the
solution tank. Drain, rinse, and refill the solution

CONVENTIONAL SCRUBBING MODE
FOR SAFETY: Before leaving or servicing
machine, stop on level surface, turn off
machine, and remove key.
1. Open the solution tank cover.
2. Partially fill solution tank with water (not to
exceed 60qC / 140qF). Pour the required
amount of detergent into the solution tank.
Continue filling the solution tank with water
until the level is approximately 50 mm (2 in)
below the cap.
WARNING: Flammable materials can
cause an explosion or fire. Do not use
flammable materials in tank(s).
ATTENTION: For Conventional Scrubbing,
only use recommended cleaning detergents.
Machine damage due to improper detergent
usage will void the manufacturer warranty.
NOTE: Pour a recommended foam control
solution into the recovery tank if excessive foam
appears. For specific detergent recommendations,
contact a Tennant representative.
3. Close the solution tank cover.
ec-H2O BUTTON (OPTION)
The ec--H2O button enables the ec--H2O system

SETTING BRUSH PRESSURE
Under normal cleaning conditions, the brush
pressure should be set to the lowest setting.
Under heavy grime conditions, the brush pressure
can be set to a higher setting. Travel speed and
floor conditions will affect cleaning performance.
If brushes are worn, it may be necessary to
increase the brush pressure. The machine will
default to the last setting used when it is powered
on or off.
T12 Only: With the 1--STEP button activated,
press either the Brush pressure increase button
(+) or Brush pressure decrease button (--) to set
the brush pressure.

SETTING SOLUTION FLOW
With the 1--STEP button activated, press either
Solution increase button (+) or Solution decrease
button (--) to set the solution flow level. Travel
speed and floor conditions will affect scrubbing
performance. Under normal soilage conditions the
solution flow level should be set to the lowest
setting (the left light). Under heavy grime
conditions, the solution flow level should be set to
the higher settings (middle or right lights). The
machine will default to the last setting used when
the machine is powered on or off. The solution
