machine has been powered on. This information is
useful when servicing the machine.
BA TTER Y DISCHARGE INDICATOR
The battery discharge indicator shows the charge
level of the batteries.
When the batteries are fully charged, the indicator
on the far right is lit. As the batteries discharge,
the indicator will move along the display to the left.
Recharge the batteries when the indicator flashes.
NOTE: The battery discharge indicator will not
reset from the flashing indicator unless the
batteries have been fully charged.

SOLUTION FLOW LEVER
The solution flow lever controls the amount of
solution flow to the floor.
Increase: Push the lever forward.
Decrease: Pull the lever backward.
NOTE: A solenoid valve dispenses the solution to
the scrub head. The valve opens when the
steering handles are rotated forward, and closes
when the steering handles are released in neutral
position.
NOTE: When using the FaST or ec--H2O system
(option), the solution flow lever is nonfunctional.
The FaST and ec--H2O system flow rates are
pre--set. The ec--H2O module has optional flow
rate settings. If solution flow adjustments are
required, contact an Authorized Service Center.
CIRCUIT BREAKERS
The circuit breakers are resettable electrical circuit
protection devices. They stop the flow of current in
the event of a circuit overload. Once a circuit
breaker is tripped, reset manually by pressing the
reset button after the breaker has cooled down.
If the overload that caused the circuit breaker to
trip is still there, the circuit breaker will continue to
stop current flow until the problem is corrected.
The circuit breakers are located on each side of
the operator console.
The chart shows the circuit breakers and the
electrical components they protect.

SOLUTION TANK HOSE
The solution tank hose is used to drain the
solution tank. The drain hose plug is removed by
turning the plug latch to loosen the plug and
pulling the plug out of the drain hose. The drain
hose is plugged by placing the hose plug in the
end of the hose and turning the plug latch to
tighten the plug.
RECOVERY TANK DRAIN HOSE
The recovery tank drain hose is used to drain the
recovery tank. The drain hose plug is removed by
turning the plug latch to loosen the plug and
pulling the plug out of the drain hose. The drain
hose is plugged by placing the hose plug in the
end of the hose and turning the plug latch to
tighten the plug.
SUPPORT ARM

the tank is lifted. The support arm engages when
the solution tank is lifted all the way open. The
arm is released by pulling up on it.

closing when the tank is lowered. Push the arm in
to lower the solution tank completely.
SQUEEGEE DOWN PRESSURE CAMS
The squeegee down pressure cams adjust the
squeegee deflection along the entire length of the
squeegee.

5680 330459 (6--05)
HOW THE MACHINE WORKS
The scrub components of the machine are a
solution tank, scrub brushes or pads, 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 or pads. The brushes or pads 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.
Three different widths of scrub heads and
squeegees are available for the machine.
The scrub head widths are as follows; the model
700 (700 mm), the model 800 (800 mm), and the
model 900 (900 mm). The 700 mm squeegee is
used with the 700 model scrub head, as well as
the 800 mm with the model 800, and the 900 mm
with the model 900.
OPERAT ION
5680 330459 (3--08)

FaST SCRUBBING SYSTEM (OPTION)
The FaST (Foam Scrubbing T e chnology) 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.
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.
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.

ec- H2O SYSTEM (OPTION)
The ec--H2O (electrically converted water) system
operates by producing electrically activated water
for cleaning.
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 applications.
NOTE: Do not enable the ec --H2O system with
conventional cleaning detergents in the solution
tank. Drain, raise and refill the solution tank with
clear cool water only before operating the ec--H2O
system. Conventional cleaning detergents/
restorers may cause failure to the ec--H2O
solution system.
NOTE: Storage or transporting machines
equipped with ec--H2O in freezing temperatures
requires special procedures. Check with a
TENNANT representative for advice.

PRE-OPERATION CHECKLIST
Check over this list of items before operating the
machine:
- Check under the machine for leaks.
- Check for wire, string, or twine wrapped
around the scrub brushes.
- Check the squeegees for wear or damage.
- Check the squeegee suction hose for
obstructions.
- Check the recovery tank cover seals for
wear or damage.
- Check that the vacuum fan inlet filter is
clean.
- FaST Scrubbing: Check the FaST PAK
(option) concentrate agent level, replace
carton as needed. See the INSTALLING
THE FaST PAK AGENT section of the
manual.
- FaST or ec- H2O Scrubbing: Check that all
conventional cleaning agents/restorers are
drained and rinsed from the solution tank.
- FaST or ec- H2O Scrubbing: Check that
solution tank is filled with clear cool water
only.

INSTALLING FaST PAK AGENT (OPTION)
NOTE: Machine must be equipped with the FaST
option before the FaST PAK agent can be
installed.
1. Remove the perforated knock--outs from the
FaST PAK Floor Cleaning Concentrate
carton. Do not remove the bag from the
carton. Pull out the bag’s hose connector on
the bottom of the bag and remove the hose
cap from the connector.
NOTE: The FaST PAK Floor Cleaning
Concentrate is specifically designed for use
with the FaST system scrubbing application.
NEVER use a substitute, machine damage will
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
solution system..
3. .Raise the solution tank and remove the front
cover to access the FaST PAK carton.
OPERAT ION
5680 330459 (10--08)

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.
