system is enabled, it is turned on and off with the
scrub switch. Disable the FaST system before
using the machine for conventional scrubbing.
Disable FaST for conventional scrubbing: Press
the top of switch to the FaST system off position.
Enable the FaST system 1: Press the middle of
switch to the low FaST system solution flow
position.
Enable the FaST system 2: Press the bottom of
the switch to the high FaST system solution flow

ec−H2O SWITCH (OPTION)
The ec−H2O switch (option) enables the ec−H2O
(Electrically activated water) system. When the
ec−H2O system is enabled, it is turned on and off
with the scrub switch.
ec−H2O low setting: Press the top of the ec−H2O
switch.
ec−H2O high setting: Place the ec−H2O switch
into the middle position.
Conventional scrubbing: Press the bottom of the
ec−H2O switch.
NOTE: The ec−H2O system will not start until the
machine starts scrubbing.
NOTE: Do not enable the ec−H2O system with
conventional cleaning detergents in the solution
tank. Drain, raise and refill the solution tank with
clear cool water only before operating the ec−H2O
system. Conventional cleaning detergents/
restorers may cause failure to the ec−H2O
solution system.
CONTROL PANEL
The sweeping and scrubbing functions are
activated by the control panel. Features of the
control panel include six multi−function buttons
and graphics icons which display the current state
of the sweeping and scrubbing functions. The
control panel also features a display clock for
operator convenience, and a maintenance mode
that prompts the operator when to perform routine
machine maintenance.
By pressing the TENNANT logo switch, the
operator can cycle the control panel display
through the different function screens. Each
function screen allows the operator to enable or
disable different sweeping and scrubbing
functions.

BATTERY DISCHARGE INDICATOR
The battery discharge indicator shows the charge
level of the batteries with a segmented display.
When the batteries are fully charged, all the
segments are lit. As the batteries discharge, the
segments shut off.
The batteries should be recharged when all the
segments have shut off. At this point, the battery
icon will begin flashing, and all sweeping and
scrubbing functions will automatically shut off to
alert the operator of the battery condition. The
squeegee and vacuum can be operated, with the
rear squeegee switch, for an additional 30
seconds to pick up any excess water.
NOTE: Do not charge the batteries more often
than is necessary to prolong the life of the
batteries. Do not charge the batteries with a “top
off” charge if there is enough remaining charge in
the batteries for the next machine use. Discharge
the batteries to a 20% level, when the battery
discharge indicator segments shut off, before fully
charging the batteries. Do not allow the batteries
to become completely discharged as this will also
damage the batteries. See BATTERIES in the
MAINTENANCE section.
HOURMETER
The hourmeter records the number of hours the
machine has been operating.
The hourmeter will record time when the machine
is propelling or when the vacuum fan is operating.
This information is useful when maintaining the
machine.
