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 m
2
(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.
