UNCRATING MACHINE
Carefully check machine for signs of damage. Report
damages at once to carrier. Contact distributor or Tennant
for missing items.
To uncrate the machine, remove straps, wheel blocks and
shipping brackets. Using the supplied ramp carefully back
the machine off the pallet. Make sure scrub head is in the
raised position.
ATTENTION: Do not remove machine from pallet
without using ramp, machine damage may occur.

battery charging data via IRIS are supplied with
a charger and set of batteries from the factory.
When a battery reaches its end of life and must
be replaced, Tennant highly recommends that
the same battery type be used to continue to
maximize the machines performance. In the event
a battery with a different amp hour (AH), type
(Flooded, AGM, Gel), or manufacturer is selected
for replacement please contact Tennant technical
service department for assistance in determining
the feasibility of the replacement batteries and
if so, selecting the correct charging profile.

T350 9016417 (09-2017)
OPERATION
HOW THE MACHINE WORKS
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.
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.
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.
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) - For maintaining highly
polished or burnished floors.
Buffing pad (Red) - For light duty scrubbing
without removing floor finish.
Scrubbing pad (Blue) −For medium to heavy
duty scrubbing. Removes dirt, spills, and scuffs.
Stripping pad (Brown) - For stripping of floor
finish to prepare the floor for recoating.
Polypropylene Side Brush −For general
sweeping of light to medium debris.
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.
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.
