personal injury.
FOR SAFETY: To identify actions that
must be followed for safe operation of
equipment.
The following information signals potentially
dangerous conditions to the operator. Know
when these conditions can exist. Locate all safety
devices on the machine. Report machine damage
or faulty operation immediately.
WARNING: Lead-acid batteries emit
hydrogen gas. Explosion or fire
can result. Keep sparks and open
flame away. Keep covers open when
charging.
WARNING: Flammable materials or
reactive metals can cause an explosion
or fire. Do not pick up.
WARNING: Raised hopper may fall.
Engage hopper support bar.
WARNING: Lift arm pinch point. Stay
clear of hopper lift arms.
WARNING: Heavy object. Back injury
could result from improper lifting. Use
hoist when removing.
WARNING: Electrical Hazard
−Disconnect Battery Cables and
Charger Plug Before Servicing Machine.
−Do Not Charge Batteries with
Damaged Power Supply Cord. Do Not
Modify Plug.
If the charger supply cord is damaged or broken,
it must be replaced by the manufacturer or its
service agent or a similarly qualified person in
order to avoid a hazard.
This machine may be equipped with technology
that automatically communicates over the cellular
network. If this machine will be operated where
cell phone use is restricted because of concerns
related to equipment interference, please contact
a Tennant representative for information on how to
disable the cellular communication functionality.

INSTALLING BATTERIES
FLOODED/SEALED LEAD−ACID BATTERIES
WARNING: Fire Or Explosion Hazard.
Batteries Emit Hydrogen Gas. Keep
Sparks And Open Flame Away. Keep
Battery Hood Open When Charging.
FOR SAFETY: When servicing machine:
Keep all metal objects off batteries. Use a
non−conductive battery removal device. Use
a hoist and adequate assistance when lifting
batteries. Battery installation must be done by
trained personnel. Follow site safety guidelines
concerning battery removal.
BATTERY SPECIFICATIONS
Six 6−volt deep cycle lead acid batteries.
Maximum battery dimensions: 28.8 in / 731 mm W
x 19.9 in / 506 mm L x 15.6 in / 395 mm H.
1. Park the machine on a level surface and
remove the key.
2. Lift the battery compartment cover open and
engage the support.
3. Remove the bracket from the rear of the
battery compartment.
4. With adequate assistance carefully install the
batteries into the battery compartment tray
and arrange the battery posts as shown. Insert
the foam spacers along side the batteries as
shown if installing the smaller batteries.
5. Using the supplied battery post boots, connect
the cables to the battery posts, RED TO
POSITIVE (+) & BLACK TO NEGATIVE (−).
IMPORTANT: Before charging, make sure
that the charger setting is properly set for the
battery type.
6. Reinstall the bracket onto the rear of the
battery compartment.

S16 9045321 (09-2020)
OPERATION
OPERATION OF CONTROLS
BATTERY DISCHARGE INDICATOR
The battery discharge indicator displays the
charge level of the batteries while the machine is
operating.
When the batteries are fully charged, all five
indicators are illuminated. Recharge the batteries
when there is only one indicator illuminated. Do not
allow the batteries to discharge below 20% (last
indicator).
NOTE: The reading on the battery discharge
indicator is not accurate when the machine is first
powered on. Operate the machine a few minutes
before reading the charge level of the batteries.
NOTE: Lithium-ion Battery Model - Do not store
the machine for an extended period if battery is
discharged to the last bar, the battery may further
discharge to a level that is unrecoverable.
WORN BRUSH INDICATOR
The worn brush indicator flashes when the main
brush motor detects the main brush is worn. For
best sweeping performance it is recommended
that the main sweeping brush always be replaced
as soon as possible when the worn brush indicator
is flashing. The worn brush indicator will eventually
illuminate solid if the main sweeping brush is
not changed when the indicator is flashing, and
sweeping performance will continue to deteriorate.
See REPLACING THE MAIN SWEEPING BRUSH
in the MAINTENANCE section for instructions how
to change the main sweeping brush.
SMART-FILL ABW (AUTOMATIC BATTERY
WATERING INDICATOR) (OPTION)
The Smart-Fill ABW indicator illuminates when
there is not adequate water in the tank to fill the
batteries. All sweep functions will cease operating
and will remain inoperable if the machine is
operated for 10 hours past when the indicator
light is initially illuminated. See SMART-FILL ABW
(AUTOMATIC BATTERY WATERING) SYSTEM in
the MAINTENANCE section for instructions how to
fill the tank.

18 S16 9045321 (09-2020)
OPERATION
HEPA (HIGH EFFICIENCY PARTICULATE
ARRESTANCE) INDICATOR (MACHINES
EQUIPPED WITH HEPA FILTRATION SYSTEM
OPTION ONLY)
The HEPA indicator illuminates when the HEPA
filter needs to be replaced due to excessive
blockage preventing air from moving through the
filter. For best sweeping performance, always
replace the HEPA filter as soon as possible when
the HEPA indicator is illuminated. See REMOVING
/ REPLACING THE HOPPER DUST FILTER in
the MAINTENANCE section for instructions how to
replace the HEPA filter.
FAULT INDICATOR
The fault indicator illuminates when a fault code
is detected. See FAULT / ALERT CODES AND
INDICATORS for additional fault code information.
