OPERATION
10 Tennant T5 (06- 15)
HOW THE MACHINE WORKS
Conventional Scrubbing:
Water and detergent from the solution tank flow to the
floor through a solution valve. The brushes use the
detergent and water to scrub the floor clean. As the
machine moves forward, the squeegee wipes the dirty
solution from the floor into the recovery tank.
ec-H2O NanoClean Scrubbing (ec-H2O Model):
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.
Foam Scrubbing (FaST Model):
(FaST-Foam activated Scrubbing Technology)
Unlike conventional scrubbing, the FaST system injects
the FaST- PAK concentrate formula with a small
amount of water and air onto the floor. The mixture
creates a large volume of expanded wet foam for the
brush to scrub the floor clean. As the machine moves
forward, the foam collapses and the squeegee
recovers the dirty solution into the recovery tank
leaving the floor clean dry and slip free.
BRUSH AND PAD INFORMATION
For best cleaning results use the appropriate brush
type for your cleaning application. Refer to the Parts
manual for part number information.
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.
Soft Nylon Bristle Scrub Brush (White) -
Recommended for cleaning coated floors without
removing finish. Cleans without scuffing.
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.
