OPERATION

HOW THE MACHINE WORKS

BRUSH AND PAD INFORMATION

Conventional scrubbing:
When using the conventional scrubbing mode, water
and detergent mixture from the solution tank flows to
the floor and the rotating brush(es)/pad(s) scrub the
floor clean. As the machine moves forward, the
squeegee with vacuum suction picks up the dirty
solution from the floor into the recovery tank.

For best cleaning results use the appropriate brush or
pad for your cleaning application. Listed below are
brushes and pads and the applications for which each
is best suited.

ec-H2O NanoClean Technology (option):
When using the ec-H2O NanoClean technology, normal
water passes through a module where it is electrically
converted into a cleaning solution. The electrically
converted water attacks the dirt, allowing the machine
to easily scrub away the suspended soil. The converted
water then returns to normal water in the recovery tank.

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.
Soft nylon bristle scrub brush (White) Recommended for cleaning coated floors without
removing finish. Cleans without scuffing.
Polypropylene bristle scrub brush (Black) This general purpose polypropylene bristle scrub brush
is used for scrubbing lightly compacted soilage. This
brush works well for maintaining concrete, wood and
grouted tile floors.
Super abrasive bristle scrub brush (Gray) Nylon fiber impregnated with abrasive grit to remove
stains and soilage. Strong action on any surface.
Performs well on buildup, grease, or tire marks.
Polishing pad (White) Used to maintain highly polished or burnished floors.
Buffing pad (Red) - Used for light duty scrubbing
without removing floor finish.
Scrubbing pad (Blue) - Used for medium to
heavy-duty scrubbing. Removes dirt, spills, and scuffs
and leaves surface clean ready for recoating.
Stripping pad (Brown) - Used for stripping of floor
finish to prepare the floor for recoating.
Heavy duty stripping pad (Black) - Used for
aggressive stripping of heavy finishes/sealers, or very
heavy duty scrubbing.
Surface preparation pad (Maroon) - Used for very
aggressive chemical free removal of floor finish to
prepare the floor for re-coating

SUPERVISOR CONTROLS
ATTENTION: The following instructions are intended
for supervisor use only. Remove pages from manual if
necessary.

Hold down the Zone Setting button until it blinks
three times to save the preferred supervisor control
mode (Figure 138). In this example, Lockout mode

SUPERVISOR CONTROLS
The supervisor controls feature allows a supervisor to
program the machine’s scrubbing settings for operator
use. The lockout functionality will prevent the operator
from changing or saving the Zone Settings.
The supervisor controls feature will lower machine
variability for consistent, repeatable cleaning results,
machine quality assurance regardless of user
experience, and reduce user training requirements.
NOTE: The T300e model is not equipped with the
supervisor controls feature.
