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,

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.
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.
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.
