OPERATION
When in the optional ES (Extended Scrub) mode,
the dirty solution in the recovery tank is filtered
through the ES system and returned to the
solution tank for reuse. Detergent is then injected
into the returned solution to revitalize the cleaning
capability of the solution.
HOW THE MACHINE WORKS
This machine can effectively scrub or sweep dirty
floors. The 1--STEP Scrub button and 1--STEP
Sweep button make it possible to immediately
begin scrubbing or sweeping.
When in the optional ec--H2O (electrically
converted water) mode, normal water passes
through a module where it is oxygenated and
charged with an electric current. The electrically
converted water changes into a blended acidic
and alkaline solution forming a neutral pH cleaner.
The converted water attacks the dirt, breaks it into
smaller particles, and pulls it off the floor surface
allowing the machine to easily scrub away the
suspended soil. The converted water then returns
to normal water in the recovery tank . The
ec--H2O system can be used with all double
scrubbing and heavy duty scrubbing applications.
The 1--STEP Sweep button operates all the dry
sweeping functions (without scrubbing). The
1--STEP Scrub button operates all the scrubbing
functions. (The machine also sweeps while
scrubbing).
When in the conventional Scrub mode, a water
and detergent mixture is used to scrub the floor.
When in the optional FaST (Foam scrubbing)
mode, the FaST scrubbing system mixes the
FaST--PAK concentrate with a small amount of
water, creating a large volume of expanded wet
foam. The FaST system can be used with all
double scrubbing and heavy duty scrubbing
applications.

OPERATION
BRUSH INFORMATION
WHILE OPERATING THE MACHINE
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.
Pick up oversized debris before scrubbing or
sweeping. Pick up wire, string, twine, large pieces
of wood, or any other debris that could become
wrapped around or tangled in the brushes.
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.
PolyPro brush -- Heavy duty polypropylene
bristles provide a more aggressive cleaning
performance and can more easily lift compacted
dirt, debris, and sand while offering excellent
scrubbing performance.
Polypropylene brush -- General purpose
polypropylene bristles lift lightly compacted dirt
without scuffing high-gloss coated floors.
Polyester brush -- Softer general purpose
polyester bristles lift light debris while sweeping
and gently clean while scrubbing. Perfect for
sensitive floor surfaces. Polyester does not
absorb water so it is preferred over Nylon in wet
applications.
Super AB brush -- Nylon fiber impregnated with
abrasive grit to remove stains and compacted dirt.
Aggressive action on any surface. Performs well
on buildup, grease, or tire marks.
Drive as straight a path as possible. Avoid
bumping into posts or scraping the sides of the
machine. Overlap the scrub/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, brush pressure, and
solution flow as required when scrubbing. Use the
lowest brush pressure and solution flow settings
for best performance. If the machine is equipped
with the FaST or ec--H2O system, use the FaST
or ec--H2O system for the best scrubbing results.
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. Scrub 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 scrubbing functions in areas where
the ambient temperature is below freezing 0_ C
(32_ F).
The maximum rated incline for scrubbing with the
machine is 10%. The maximum rated incline
during transport of the machine is14%.

FOR SAFETY: When servicing machine, use
cardboard to locate leaking hydraulic fluid
under pressure.
High pressure fluid escaping from a very small
hole can almost be invisible, and can cause
serious injuries.
00002
If using a locally-available hydraulic fluid, be sure
the specifications match Tennant hydraulic fluid
specifications. Substitute fluids can cause
premature failure of hydraulic components.
Consult a physician immediately if injury results
from escaping hydraulic fluid. Serious infection or
reaction can occur if proper medical treatment is
not given immediately.
ATTENTION! Hydraulic components depend
on system hydraulic fluid for internal
lubrication. Malfunctions, accelerated wear,
and damage will result if dirt or other
contaminants enter the hydraulic system.
Contact a mechanic or supervisor if a leak is
discovered.

CLEANING THE HOPPER DUST FILTER
WATER--Rinse the dust filter with a low pressure
garden hose through the dust filter opposite the
direction of the arrows.
Shake the dust filter before emptying the hopper
and at the end of every shift. Inspect and clean
the filter after every 20 hours of operation.
Replace damaged dust filters.
NOTE: The dust filter may need to be cleaned at
more frequent intervals if the machine is used in
extremely dusty conditions.
Use one of the following methods to clean the
dust filter:
SHAKING--Press the filter shaker button.
TAPPING--Tap the filter, with the dirty side down,
gently on a flat surface. Do not damage the
edges of the filter. The filter will not seal properly
in the filter frame if the edges of the filter are
damaged.
NOTE: If water is used to clean the dust filter, be
sure the filter is completely dry before reinstalling
it into the hopper. Do Not reinstall a wet dust
filter.
THERMO--SENTRY
The Thermo--Sentry, located inside the
hopper, senses the temperature of the air pulled
up from the hopper. If there is a fire in the hopper,
the Thermo--Sentry stops the vacuum fan and
cuts off the air flow. The Thermo--Sentry
automatically resets after cooling down.
AIR--Always wear eye protection when using
compressed air. Blow air through the dust filter
opposite the direction of the arrows. Never use
more than 690 kPa (100 psi) of air pressure and
never hold the nozzle closer than 50 mm (2 in) to
the filter. This may be done with the dust filter in
the machine.

PUSHING, TOWING, AND TRANSPORTING
THE MACHINE
PUSHING OR TOWING THE MACHINE
If the machine becomes disabled, it can be
pushed from the front or rear, but only towed from
the front.
The propelling pump has a bypass valve to
prevent damage to the hydraulic system when the
machine is being pushed or towed. This valve
allows a disabled machine to be moved for a very
short distance and at a speed to not exceed 1.6
kp/h (1 mph). The machine is NOT intended to be
pushed or towed a long distance or at a high
speed.
TRANSPORTING THE MACHINE
1. Raise the squeegee, scrub head, and
brushes. If necessary, raise the hopper for
additional ramp clearance.
FOR SAFETY: When loading machine onto
truck or trailer, drain tanks and empty hopper
before loading machine.
2. Position the rear of the machine at the loading
edge of the truck or trailer.
3. If the loading surface is not horizontal or is
higher than 380 mm (15 in) from the ground,
use a winch to load machine.
If the loading surface is horizontal and 380
mm (15 in) or less from the ground, the
machine may be driven onto the truck or
trailer.
ATTENTION! Do not push or tow machine for
a long distance or damage may occur to the
propelling system.
Turn the bypass valve located on the bottom of
the propelling pump 90_ (either direction) from the
normal position before pushing or towing the
machine. Return the bypass valve back to the
normal position when through pushing or towing
the machine. Do Not use the bypass valve during
normal machine operation.
FOR SAFETY: When loading machine onto
truck or trailer, use winch. Do not drive the
machine onto the truck or trailer unless the
loading surface is horizontal AND is 380 mm
(15 in) or less from the ground.
4. To winch the machine onto the truck or trailer,
attach the winching chains to the holes in the
rear jacking brackets behind the rear tires.

5. Position the machine as close to the front of
the trailer or truck as possible.
6. Set the parking brake and place a block
behind each wheel to prevent the machine
from rolling.
7. Lower the scrub head.
9. Route the tie--downs to the opposite ends of
the machine and hook them to the brackets
on the floor of the trailer or truck. Tighten the
tie--down straps.
NOTE: It may be necessary to install tie-down
brackets to the floor of the trailer or truck.
FOR SAFETY: When loading/unloading
machine onto/off truck or trailer, lower scrub
head and squeegee before tying down
machine.
8. Connect the tie--down straps to the holes in
the right and left lower corners in front of the
machine and the holes in the rear jacking
brackets behind the rear tires.
10. If the loading surface is not horizontal or is
higher than 380 mm (15 in) from the ground,
use a winch to unload machine.
If the loading surface is horizontal AND is 380
mm (15 in) or less from the ground, the
machine may be driven off the truck or trailer.
FOR SAFETY: When unloading machine off
truck or trailer, use winch. Do not drive the
machine off the truck or trailer unless the
loading surface is horizontal AND 380 mm
(15 in) or less from the ground.
