HOW THE MACHINE WORKS
The scrub components of the machine are a
solution tank, scrub brushes or pads, a squeegee,
a vacuum fan, and a recovery tank.
The buttons on the control panel control the
machine scrubbing functions. The One Step
Scrub button turns the preset scrub functions on
and off. The FaST button (option) enables the
FaST (Foam Scrubbing Technology) system. The
ec- H2O button (option) enables the ec- H2O
(electrically converted water) system. The
vacuum fan / squeegee button turns the vacuum
fan on/off and raises and lowers the squeegee.
The brush pressure buttons control the scrub
brush pressure, and the solution buttons control
the solution flow.
The steering wheel controls the path of the
machine travel. The directional switch controls the
forward or reverse direction of the machine. The
propel pedal controls the speed of the machine.
The brake pedal slows and stops the machine.
There are two different types of scrub heads
available, cylindrical and disk. Both scrub heads
are available in two different widths. The Disk
scrub head is available in 650 mm (26 in) wide and
800 mm (32 in) wide. The Cylindrical scrub head is
available in 700 mm (28 in) wide and 800 mm
(32 in) wide.
NOTE:The amount and type of soilage play an
important role in determining the type of brushes
or pads to use. For specific recommendations,
see the BRUSH INFORMATION section of this
manual or contact a Tennant representative.
CONVENTIONAL SCRUBBING
Water and detergent from the solution tank flow to
the floor through a solution valve. The brushes
use the detergent and water solution to scrub the
floor clean. As the machine propels forward, the
squeegee wipes the dirty solution from the floor.
The suction created by the vacuum fan then
draws the dirty solution from the squeegee into
the recovery tank.
FOAM SCRUBBING SYSTEM (FaST MODEL)
Unlike conventional scrubbing, the optional FaST
(Foam Scrubbing Technology) system operates
by injecting the FaST- PAK concentrate agent into
the system with a small amount of water and air.
This mixture creates a large volume of expanded
wet foam.
The expanded foam mixture is then dispersed
onto the floor while the machine is scrubbing.
When the squeegee picks up the mixture, the
patented foaming agent has collapsed and is
recovered into the recovery tank.
The FaST system can be used with all double
scrubbing and heavy duty scrubbing applications.
Using the FaST system improves safety and can
increase productivity by 30% by reducing your
dump/fill cycle. It will also reduce chemical usage
and storage space. One FaST- PAK of
concentrated agent can scrub up to 90,000 m2(1
million square feet).
NOTE: Do not use the FaST system with
conventional cleaning detergents in the solution
tank. Drain, rinse and refill the solution tank with
clear cool water before operating the FaST
system. Conventional cleaning detergents may
cause failure to the FaST system.

OPERATION
8T7 331040 (9- 2013)
ec- H2O SCRUBBING (ec- H2O Model)
The ec- H2O (electrically converted water) system
operates by producing electrically converted water
for cleaning.
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 applications.
NOTE: Do not enable the ec- H2O system with
conventional cleaning detergents in the solution
tank. Drain, raise and refill the solution tank with
clear cool water only before operating the
ec- H2O system. Conventional cleaning
detergents/ restorers may cause failure to the
ec- H2O solution system.
NOTE: Storage or transporting machines
equipped with ec- H2O in freezing temperatures
requires special procedures. Follow the freeze
protection procedure located in the STORAGE
INFORMATION section.
BRUSH INFORMATION
For best results, use the correct brush type for the
cleaning application. The following are
recommended brush applications.
Non-scuff polypropylene brush (Cylindrical
and Disk) - This brush uses a softer, general
purpose polypropylene bristle to lift lightly
compacted soilage without scuffing high-gloss
coated floors.
Nylon brush (Cylindrical and Disk) - Softer
nylon bristles are recommended for scrubbing
coated floors. Cleans without scuffing
Super abrasive bristle brush (Cylindrical and
Disk) - Nylon fiber impregnated with abrasive grit
to remove stains and soilage. Strong action on
any surface. Performs well on buildup, grease, or
tire marks.
Surface preparation pad - This maroon pad is
for very aggressive floor stripping.
Heavy duty stripping pad - This black pad is for
stripping floors. Cuts through old heavy finishes
easier to prepare the floor for recoating.
Stripping pad - This brown pad is for stripping
floors. Quickly and easily cuts through old finish to
prepare the floor for recoating.
Scrubbing pad - This blue pad is for scrubbing
floors. Removes dirt, spills, and scuffs. Leaves a
clean surface ready for recoating.
Buffing pad - This red pad is for buffing floors.
Quickly cleans and removes scuff marks while
polishing the floor to a high gloss.
Polishing pad - This white pad is for polishing
floors. Maintains a high gloss. Use for buffing very
soft finishes and lower traffic areas, and polishing
soft waxes on wood floors.

the machine is in motion. The machine is very
responsive to the movement of the steering wheel.
Avoid sudden turns, except in emergencies.
When scrubbing dead end aisles, start at the
closed end of the aisle and scrub out towards the
opening.
Adjust the machine speed, brush pressure, and
solution flow as required when scrubbing. Use the
minimal brush pressure and solution flow settings
as possible.
Keep the machine moving to prevent damaging
floor finishes.
If poor scrubbing performance is observed, stop
scrubbing and refer to MACHINE
TROUBLESHOOTING.
Conventional Scrubbing: Pour a recommended
foam control solution into the recovery tank if
excessive foam appears.
ec- H2O SCRUBBING: If an alarm sounds and
the ec- H2O system indicator light begins to blink
red, the ec- H2O module must be flushed to
resume ec- H2O operation (See ec- H2O
MODULE FLUSH PROCEDURE on page 37)
NOTE: When the alarm sounds and the light
blinks red, the machine will bypass the ec- H2O
system. To continue scrubbing, turn the ec- H2O
switch off and change over to conventional
scrubbing.
Change or rotate pads as necessary.
Observe the battery discharge indicator to ensure
there is adequate charge for machine operation.
Observe the solution tank indicator to ensure the
solution tank is not empty. Always empty recovery
tank before refilling the solution tank.
Observe the recovery tank indicator to ensure the
recovery is not full.
Remove the key when leaving the machine
unattended.
Perform the Daily Maintenance Procedures after
scrubbing (see MACHINE MAINTENANCE).
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.

OPERATION

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 19.25%.
EMERGENCY STOP BUTTON
The Emergency Stop Button halts all power to the
machine in case of an emergency. Press the
button to halt the machine power. To restart the
machine, turn the Emergency Stop Button to the
right. Then turn the on/off switch to the off position
and then to the on position.

SOLUTION TANK EMPTY INDICATOR
The solution tank empty indicator comes on when
the solution tank is empty. When this happens,
the scrub functions are disabled. If necessary,
press the ONE STEP Scrub button for an
additional minute of operation to pick up standing
water or solution.
RECOVERY TANK FULL INDICATOR
The recovery tank full indicator comes on when
the recovery tank is full. When this happens, the
scrub functions are disabled. If necessary, press
the ONE STEP Scrub button for an additional
minute of operation to pick up standing water or
solution.
BATTERY DISCHARGE INDICATOR
The battery discharge indicator shows the charge
level of the batteries.
When the batteries are fully charged, all five lights
are lit. As the batteries discharge, the lights go out
until only the left light is blinking.
When the left light blinks, the scrubbing functions
will shut off to alert the operator of the battery
condition. The machine will still propel when the
light is blinking. Recharge the batteries when the
light blinks. If necessary, press the ONE STEP
Scrub button for an additional minute of operation
to pick up standing water or solution.
NOTE: Do not charge batteries more often than
necessary. Excessive charging could reduce the
life of the batteries. It is best to charge the
batteries only when the left light indicates that the
battery needs charging. See BATTERIES in the
MAINTENANCE section.
NOTE: The blinking left battery discharge light will
not reset from blinking until the batteries are fully
charged.
