OPERATION

BRUSH INFORMATION

For best results, use the correct brush type for the
cleaning application.

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.

Polypropylene and Wire 8-double row Main
Brush − Recommended for general sweeping,

fine dust, and slightly impacted debris.

Polypropylene Sand Wedge Main Brush −

Recommended for heavy accumulation of sand
and other small particulates.

Polypropylene Window Main Brush −
Recommended for light litter, especially on
smooth floors.

Polypropylene 8-double row Main Brush −
Recommended for lighter duty sweeping
applications.

HOW THE MACHINE WORKS

Machines SN 000000 − 006500

Nylon 8-double row Main Brush −

Recommended for general sweeping, especially
on rough or irregular surfaces. Nylon has a long
wear life.

Nylon Full Fill Main Brush − Recommended for
accumulation of sand and other small particulates.
Nylon has a long wear life.

Nylon Patrol Main Brush − Recommended for
bulky debris swept at faster speeds.

Wire 8-double row Main Brush −
Recommended for general sweeping and slightly
impacted debris.

Natural Fiber and Full Fill Main Brush −
Recommended for accumulation of sand and
other small particulates.

Polypropylene Side Brush − Recommended for
general sweeping of light to medium debris.

Nylon Side Brush − Recommended for general
sweeping of rough or irregular surfaces. Nylon
has a long wear life.

Machines SN 006501 −

The steering wheel controls the direction of
machine travel. The directional pedal controls the
speed and forward/reverse direction. The brake
pedal slows and stops the machine.

The side brush sweeps debris into the path of the
main brush. The main brush sweeps debris from
the floor into the hopper. The vacuum system
pulls dust and air through the hopper and the dust
control system.

The machine also has a wet side brush dust
control option to help contain dust.

When sweeping is finished, shake the dust filter
and empty the hopper.

Flat Wire Side Brush − Recommended for
outdoor curb-side sweeping where dirt is heavy or
compacted.

STARTING THE MACHINE

OPERATION

4. Turn the ignition switch key until the engine
starts.

1. LPG powered machines: Slowly open the
liquid service valve.

NOTE: Opening the service valve too quickly may
cause the service check valve to stop the flow of
LPG fuel. If the check valve stops the fuel flow,
close the service valve, wait a few seconds, and
slowly open the valve again.

2. Sit in the operator seat and press the brake
pedal or set the parking brake.

FOR SAFETY: When starting machine, keep
foot on brake and directional pedal in neutral.

NOTE: Do not operate the starter motor for more
than 10 seconds at a time or after the engine has
started. Allow the starter to cool 15−20 seconds
between starting attempts or damage to the
starter motor may occur.

5. Allow the engine and hydraulic system to
warm up for three to five minutes.

WARNING: Machine emits toxic gases.
Severe respiratory damage or
asphyxiation can result. Provide
adequate ventilation. Consult with your
regulatory authorities for exposure
limits. Keep engine properly tuned.

3. S30: Place the Engine speed switch into the

idle position.

S30 XP and X4: The engine will automatically
start in the idle speed.

6. Turn on lights.

TURNING OFF THE MACHINE

1. Stop the machine and turn off all sweeping
functions.

2. Turn the ignition switch key counter clockwise
to turn off the machine. Remain in the
operator seat until the engine is off.

CAUTION: LPG engine will run for a few
seconds after key is turned off. Apply
parking brake before leaving machine.

NOTE: To protect engine emission components
on LPG powered machines, the engine will
continue to operate for a few seconds after the
ignition switch is turned off.

FOR SAFETY: Before leaving or servicing
machine, do not park near combustible
materials, dust, gases, or liquids. Stop on
level surface, set parking brake, turn off
machine, and remove key.

OPERATION

WHILE OPERATING THE MACHINE

Pick up oversized debris before sweeping. Pick
up wire, string, twine, large pieces of wood, or any
other debris that could become wrapped around
or tangled in the brushes.

Drive as straight a path as possible. Avoid
bumping into posts or scraping the sides of the
machine. Overlap the sweep paths by several
centimeters (a few inches).

Avoid turning the steering wheel too sharply when
the machine is in motion. The machine is very
responsive to the movement of the steering wheel.
Avoid sudden turns, except in emergencies.

Adjust the machine speed and brush pressure.
Use the lowest brush pressure for best
performance.

Keep the machine moving to prevent damaging
floor finishes.

If poor cleaning performance is observed, stop
cleaning and refer to MACHINE
TROUBLESHOOTING in this manual.

Perform the Daily Maintenance Procedures after
each use (see MACHINE MAINTENANCE in this
manual).

Drive the machine slowly on inclines. Use the
brake pedal to control machine speed on
descending inclines. Sweep with the machine up
inclines rather than down inclines.

FOR SAFETY: When using machine, go slowly
on inclines and slippery surfaces.

Do not operate machine in areas where the
ambient temperature is above 43_ C (110_ F). Do
not operate sweeping functions in areas where
the ambient temperature is below freezing 0_ C
(32_ F). With the proper hydraulic fluid and a
machine warm−up period, the machine is capable
of operating at much lower temperatures.

FOR SAFETY: Do not sweep on ramp inclines
that exceed 14% grade or transport (GVWR)
on ramp inclines that exceed 17% grade.
