OPERATION
HOW THE MACHINE WORKS
The scrub components of the machine are a
solution tank, scrub brushes, a squeegee, a
vacuum fan, and a recovery tank.
Water and detergent, from the solution tank, flow
to the floor through a solution valve to the scrub
brushes. The brushes scrub the floor. As the
machine is moved forward the squeegee wipes
the dirty solution off the floor, which is then picked
up and drawn into the recovery tank.
The steering handles control the direction and
speed of the machine in forward or reverse. By
rotating the steering handles forward, the machine
propels forward. By rotating the handles towards
you the machine propels backward.
When using the ES mode, the dirty solution in the
recovery tank is filtered and returned to the
solution tank to be reused.
Three different widths of scrub heads and

OPERATION
FaST SCRUBBING SYSTEM (OPTION)
The FaST (Foam Scrubbing Technology) system
operates by injecting the FaST PAK concentrate
agent (A) into the system with a small amount of
water and compressed air. This mixture creates a
large volume of expanded wet foam.
The expanded foam mixture is then dispersed
onto the floor (B) while the machine is scrubbing.
When the squeegee picks up the mixture, the
patented foaming agent has collapsed and is
recovered into the recovery tank.
A
B
The FaST system can be used with all double
scrubbing and heavy duty scrubbing applications.
Using the FaST system can increase
productivity by 30% by reducing your dump/fill
cycle. It will also reduce chemical usage and
storage space. One FaST PAK of concentrated
agent can scrub up to 1 million sq. ft.
The safe scrubbing alternativet
NOTE: Do not enable the FaST system with
conventional cleaning detergents in the solution
tank. Drain, raise and refill the solution tank with
clear cool water only before operating the FaST
system. Conventional cleaning detergents/
restorers may cause failure to the FaST solution
system.
NOTE: Storage or transporting machines
equipped with FaST in freezing temperatures
requires special procedures. Check with a
TENNANT representative for advice.

result.
FOR SAFETY: When using machine,
always follow the handling instructions
on chemical container.
2. Empty the solution tank. See the DRAINING
AND CLEANING THE TANKS section of the
manual.
NOTE: When scrubbing with the FaST system
option, use clean water only. Do not add cleaning
agents in the solution tank. Conventional cleaning
agents/restorers may cause failure to the FaST

4. Place the FaST PAK carton in the carton
holder under the front cover of the machine.
Connect the supply hose to the FaST PAK
bag.
NOTE: If any dried concentrate is visible on the
supply hose connector or the on the FaST PAK
connector, soak and clean with warm water.
5. Make sure to connect the supply hose onto
the hose storing plug when the supply hose
is not connected to the FaST PAK. This will
prevent the FaST solution system from
drying out and clogging up the hose.
6. When replacing an empty FaST PAK carton,
allow the new FaST PAK detergent to
gravity feed into the system for several
minutes prior to operating the FaST system.
If the detergent does not flow out of the
FaST PAK, simply squeeze and release the
hose several times. If the previous FaST
PAK was run dry, it may take up to 3
minutes of operation to remove any air
pockets in the system before you achieve
maximum foaming.

LUBRICATION
REAR CASTERS
The rear casters each have one grease fitting on
the caster swivel. Lubricate the caster with a
grease gun containing Lubriplate EMB grease
(TENNANT part no. 01433--1) every 100 hours of
machine operation.
TRANSAXLE
Check the transaxle lubricant level every 1000
hours of operation by removing one of the orange
filler plugs. If needed, add SAE 90 weight gear
lubricant.
BATTERIES
The batteries are unique in that they hold their
power for long periods of time. The lifetime of the
batteries is limited by the number of charges the
batteries receive. To get the most life from the
batteries, charge them when the battery discharge
indicator blinks.
Periodically clean the top surface of the batteries
and the terminals, and check for loose
connections. Use a strong solution of baking soda
and water. Brush the solution sparingly over the
battery tops, terminals, and cable clamps. Do not
allow any baking soda solution to enter the
batteries. Use a wire brush to clean the terminal
posts and the cable connectors. After cleaning,
apply a coating of clear battery post protectant to
the terminals and the cable connectors. Keep the
tops of the batteries clean and dry.

MAINTENANCE
Keep all metallic objects off the top of the
batteries, which may cause a short circuit.
Replace any worn or damaged wires.
Check the electrolyte level in each battery cell
before and after charging, and after every 50
hours of operation. Do not charge the batteries
unless the fluid is slightly above the battery plates.
If needed, add just enough distilled water to cover
the plates. Never add acid to the batteries. Do not
overfill. Always keep the battery caps on, except
when adding water or taking hydrometer readings.
Measuring the specific gravity, using a
hydrometer, is a way to determine the charge
level and condition of the batteries. If one or more
of the battery cells test lower than the other
battery cells (0.050 or more), the cell is damaged,
shorted, or is about to fail.
NOTE: Do not take readings immediately after
adding distilled water. If the water and acid are not
thoroughly mixed, the readings may not be
accurate. Check the hydrometer readings against
the following chart to determine the remaining
battery charge level:

NOTE: If the readings are taken when the battery
electrolyte is any temperature other than 27_ C
(80_ F), the reading must be temperature
corrected. Add or subtract to the specific gravity
reading 0.004, 4 points, for each 6_ C (10_ F)
above or below 27_C (80_ F).

1. Position the rear of the machine at the
loading edge of the truck or trailer.
FOR SAFETY: Use truck or trailer that
will support the weight of the machine.
NOTE: Empty the recovery and solution tanks
before transporting the machine.
2. 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 is
380 mm (15 in) or less from the ground, the
machine may be pushed onto the truck or
trailer.
3. To winch the machine onto the truck or
trailer, attach the winching chains to the rear
tie down locations on either side of the
machine frame by the rear casters.
4. Unplug the drive motor from the electrical
harness before attempting to winch the
machine. The machine will become easier to
maneuver when it is unplugged.
FOR SAFETY: When loading machine
onto truck or trailer, use winch. Do not
push the machine onto the truck or
trailer unless the loading surface is
horizontal AND is 380 mm (15 in) or less
from the ground.
5. Position the machine onto the truck or trailer
as far as possible. If the machine starts to
veer off the centerline of the truck or trailer,
stop and straighten the machine.

installed, lower the squeegee, and set the
machine parking brake, if equipped when
transporting the machine. Block the machine
tires and tie down the machine to the truck
or trailer before transporting.
NOTE: Do not use the steering handles to
secure the machine for transport.
Secure a strap over the top of the machine
to prevent the machine from tipping.
The rear tie-down locations are on either
side of the machine frame by the rear
casters.
7. 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 pushed off the truck or
trailer.
FOR SAFETY: When unloading machine
off truck or trailer, use winch. Do not
push the machine off the truck or trailer
unless the loading surface is horizontal
AND 380 mm (15 in) or less from the
ground.

MACHINE JACKING
Empty the recovery and solution tanks before
jacking the machine. You can jack up the machine
for service anywhere under the recovery tank.
Use a hoist or jack that will support the weight of
the machine. Use a piece of wood to distribute the
machine weight load.
Always stop the machine on a flat level surface
and block the machine tires before jacking up the
machine.
FOR SAFETY: When servicing machine,
block machine tires before jacking
machine up.
FOR SAFETY: When servicing machine,
jack machine up at designated locations
only. Block machine up with jack
stands.
STORAGE INFORMATION
The following steps should be taken when storing
the machine for extended periods of time.
1. Drain and clean the solution and recovery
tanks.
2. Park the machine in a cool, dry area.
3. Remove the batteries, or charge them after
every three months.
FREEZE PROTECTION
1. Be sure the solution tank is empty.
2. Pour 3.8 L (1 gal) of pre-mixed
automotive-type windshield washer solution
into the solution tank.
3. Turn the machine power on.
4. Start the solution flow. Start the power wand
solution system or ESt system to circulate
the washer solution through the
components.
5. The washer solution does not need to be
drained from the solution tank.
