OPERATION OF CONTROLS
PROPEL CONTROL HANDLES
The propel control handles control the direction of
the machine.
To move the machine forward, wrap the fingers
around the stationary handle, then press the
palms of the hand against the propel handle. To
stop the machine, release the handle.
To move the machine backward, squeeze the
reverse propel handle. To stop the machine,

automatic filter shaker. When the switch is in the
“on” position, the filter shaker motor will shake the
dust from the filter for 20 seconds when the
machine is turned off. The switch should be in the
“on” position during normal operation.
When the switch is in the “off” position, the filter
shaker motor will not operate when the machine is
turned off. The switch should be in the “off”
position when servicing the machine.

BATTERY CHARGE INDICATOR
The battery discharge indicator shows the charge
level of the batteries.
When the batteries are fully charged, all seven
lights are lit.
As the batteries discharge, the lights go out until
only the left light is blinking. Sweeping functions
will continue. Recharge the batteries when only
the left light is blinking.
When the red light lights up, the machine will
completely shut down.
NOTE: Do not charge batteries more often than
necessary. Excessive charging could reduce the
life of the batteries. It is best to charge the
batteries only when the left light indicates that the
battery needs charging. See BATTERIES in the
MAINTENANCE section.
NOTE: The blinking left battery discharge light will
not reset from blinking until the batteries are fully
charged.
BATTERY CHARGER PANEL
The battery charger panel shows the status of
charging after the charger has been plugged into
a wall outlet.

CIRCUIT BREAKERS AND FUSES
Circuit breakers are resettable electrical circuit
protection devices that stop the flow of current in
the event of a circuit overload. Once a circuit
breaker has tripped, allow breaker to cool and
then press the reset button to manually reset the
breaker.
The fuse is a one-time protection device designed
to stop the flow of current in the event of a circuit
overload. The 15 A fuse is located behind the
hopper on the main frame.
NOTE: Always replace the fuse with a fuse of the
same type and amperage.
The following chart shows the various circuit
breakers and fuses and the electrical components
they protect.

BRUSH INFORMATION
For best results, use the correct brush type for the
cleaning application. Listed below are the brushes
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 brushes
to use. Contact a Tennant representative for
specific recommendations.
Nylon 6-Double Row Main Brush --
Recommended for general sweeping, and has
good hopper loading. Nylon has the longest life of
the bristle types. Use this brush for sweeping
rough or irregular surfaces.
Polypropylene 6-Double Row Main Brush --
Superior pick-up of sand, gravel, and paper litter.
Polypropylene retains its stiffness when wet and
can be used indoors or outdoors with equal
performance. Not recommended for
high-temperature debris.
Fiber and Wire 6-Row Main Brush -- Offers
good sweeping action and pickup in heavy dust
concentrations. This brush is recommended
where soilage is slightly encrusted. The brush is
not recommended for heavy buildup or hard
packed soilage.
Natural Fiber 18- Row Main Brush -- T h e
natural choice for cleaning fine debris on carpet
and sweeping very heavy dust and other fine
particles on hard surfaces.

MACHINE OPERATION
PRE--OPERATION CHECKLIST
-Check the battery charge level.
-Check the hopper lip skirt for damage and
wear.
-Check the hopper seal for damage and wear.
-Check the dust filter for damage.
-Check the condition of the main brush.
Remove any string, banding, plastic wrap, or
other debris wrapped around the brush.

long runs with minimum stopping and starting.
Overlap brush paths. Sweep as straight a path as
possible. Avoid bumping into posts or scraping the
sides of the sweeper. Sweep debris from very
narrow aisles into main aisles ahead of time. Do
an entire floor or section at one time.
Pick up oversize debris before sweeping. Pick up
pieces of wire, twine, or string, which could
become entangled in brush or brush plugs.
1. Turn the on--off switch key to the on
position.
2. Release the machine parking brake, if
equipped.
