OPERATION
FOAM SCRUBBING SYSTEM (FAST MODE)
HOW THE MACHINE WORKS
The machine solution tank, scrub brushes,
squeegee, vacuum fan, and recovery tank work
together to effectively clean dirty floors.
Water and detergent from the solution tank flow to
the floor through a solution valve. The brushes
use the detergent and water solution to scrub the
floor clean. As the machine propels forward, the
squeegee wipes the dirty solution from the floor.
The suction created by the vacuum fan then
draws the dirty solution from the squeegee into
the recovery tank.
Unlike conventional scrubbing, the optional FaST
(Foam Scrubbing Technology) system operates by
injecting the FaST--PAK concentrate agent into
the system with a small amount of water and air.
This mixture creates a large volume of expanded
wet foam.
The expanded foam mixture is then dispersed
onto the floor 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 steering wheel controls the path of the
machine travel. The directional switch controls the
forward or reverse direction of the machine. The
propel pedal controls the speed of the machine.
The brake pedal slows and stops the machine.
The buttons on the control panel control the
machine scrubbing functions. The One Step
Scrub button turns the preset scrub functions on
and off. The FaST button controls use of the
Foam scrubbing system. The vacuum fan /
squeegee button turns the vacuum fan on/off and
raises and lowers the squeegee. The brush
pressure buttons control the scrub brush
pressure, and the solution buttons control the
solution flow.
There are two different types of scrub heads
available, cylinderical and disk. Both scrub heads
are available in two different widths. The Disk
scrub head is available in 650 mm (26 in) wide and
800 mm (32 in) wide. The Cylinderical scrub head
is available in 700 mm (28 in) wide and 800 mm
(32 in) wide.
NOTE: The amount and type of soilage play an
important role in determining the type of brushes
or pads to use. For specific recommendations,
see the BRUSH INFORMATION section of this
manual or contact a Tennant representative.
The FaST system can be used with all double
scrubbing and heavy duty scrubbing applications.
Using the FaST system improves safety and 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 90,000 m2 (1
million square feet).
NOTE: Do not use the FaST system with
conventional cleaning detergents in the solution
tank. Drain, rinse and refill the solution tank with
clear cool water before operating the FaST
system. Conventional cleaning detergents may
cause failure to the FaST system.

BATTERIES
LEAD ACID BATTERIES
The batteries are designed to hold their power for
long periods of time. The lifetime of the batteries
is limited to number of charges the batteries
receive. To get the most life from the batteries,
recharge them immediately when the battery
discharge indicator begins to blink.
Check the electrolyte level in each battery cell
before and after charging, and after every 50
hours of operation. Never add acid to the
batteries. Add distilled water only. Always keep
the battery caps on, except when adding water or
taking hydrometer readings.
FOR SAFETY: When servicing machine, wear
protective gloves when handling batteries or
battery cables. Avoid contact with battery
acid.
Using a hydrometer, measure the specific gravity
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 near failure.
Completely recharge the batteries and then retest.
After every 200 hours of use check for loose
battery connections and clean the surface of the
batteries, including terminals and cable clamps,
using a strong solution of baking soda and water.
Brush the solution sparingly over the battery tops.
Do not allow any baking soda solution to enter the
batteries. Use a wire brush to clean the terminal
posts and the cable connectors. Wipe off all
cleaning solution residue. 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.
Objects made of metal can potentially short circuit
the batteries. Keep all metallic objects off the
batteries. Replace any worn or damaged wires.
Replace any defective batteries. To dispose of
batteries, contact a battery dealer or your Tennant
Service representative.

MAINTENANCE
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).
CHARGING THE BATTERIES WITH
OFF--BOARD CHARGER
1. Drive the machine to a flat, dry surface.
NOTE: Make sure the area is well ventilated.
4. Lead acid batteries: Check the water level in
all battery cells. If the level is low, add just
enough distilled water to cover the plates. DO
NOT OVERFILL. The batteries can overflow
during charging due to expansion.
NOTE: Make sure the battery caps are in place
while charging.
FOR SAFETY: When servicing machine, wear
protective gloves when handling batteries or
battery cables. Avoid contact with battery
acid.
5. Plug the charger connector into the machine
battery charging connector.
2. Turn the machine ON/OFF key switch off.
