INSTALLING BATTERIES
WARNING: Batteries emit hydrogen gas.
Explosion or fire can result. Keep sparks and open
flame away when charging.
FOR SAFETY: When servicing machine, wear
appropriate personal protection equipment as
needed. Avoid contact with battery acid.
BATTERY SPECIFICATIONS
Requires four 6 volt deep-cycle batteries, ≤260 Ah @
20 hr.
Contact distributor or Tennant for battery
recommendations.
FOR SAFETY: Before leaving or servicing machine,
stop on level surface, turn off machine, remove key
and set parking brake if equipped.
1. Lift the recovery tank to access the battery
compartment (Figure 1).
FIG. 1
2. Carefully install the batteries into the battery
compartment tray and arrange the battery posts as
shown (Figure 2). Position foam spacer between
batteries as shown.
FOR SAFETY: When servicing machine, use a
hoist or adequate assistance when lifting batteries.
FOAM SPACER
FIG. 2
3. Using the supplied battery post boots, connect the
cables to battery posts, RED TO POSITIVE (+) &
BLACK TO NEGATIVE (-) (Figure 3).
BLACK
RED
FIG. 3
IMPORTANT: Before charging batteries, make sure
the battery charger and the machine's battery
discharge indicator are properly set for battery
type. Failure to properly set will result in battery
damage. See BATTERY CHARGER SETTINGS.
ATTENTION: Do not disconnect battery cables
while charger is plugged in, circuit board damage
may result.
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.

OPERATION
Tennant T500 (01-2017) 13
BRUSH AND PAD INFORMATION
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.
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 re-coating.
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.
Turf scrubbing pad (Green) - Used to scrub uneven
floor surfaces with crevices, cracks and deep grout
lines.

FILLING SOLUTION TANK
FOR SAFETY: Before leaving or servicing machine,
stop on level surface, turn off machine, remove key
and set parking brake if equipped.
The machine is equipped with two solution tank fill-port
locations. A front bucket fill-port and a rear hose fill-port

FIG. 19
1. Fill the solution tank with water until level reaches
the ”3/3” mark on the solution tank drain hose
indicator (Figure 20).
ec-H2O Scrubbing (Option)- Only use cool clean
water (less than 21ºC). Do not use hot water or add
conventional floor cleaning detergents. An ec-H2O
system fault will occur if cleaning detergents are
added.
Conventional Scrubbing - Use hot water (60ºC
maximum). Pour a recommended cleaning
detergent into the solution tank according to mixing
instructions on the container.
ATTENTION: For Conventional Scrubbing, only use
commercially approved cleaning detergents. Machine
damage due to improper detergent usage will void the
manufacturer's warranty.
WARNING: Flammable materials can cause an
explosion or fire. Do not use flammable materials
in tank(s).
NOTE: Do not use the ec-H2O system when there are
conventional cleaning detergents in the solution tank.
Drain, rinse, and refill the solution tank with clear cool
water before operating the ec-H2O system. See
DRAINING TANKS.
FIG. 20
2. After filling the solution tank make sure the front
and rear fill-port covers are securely in place
(Figure 21).
FIG. 21
