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
squeegees are available for the machine, along
with two different brush types.
The scrub head widths are as follows; the model
700 (700 mm (28 in)), the model 800 (800 mm
(32 in)), and the model 900 (900 mm (36 in)). The
700 mm (28 in) squeegee is used with the 700
model scrub head, as well as the 800 mm (32 in)
with the model 800, and the 900 mm (36 in) with
the model 900. The two available brush types are
disk and cylindrical.

5700 MM400 (6--04)
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.

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

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’s needle remains in the red zone of the
indicator.
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.
54
5700 MM400 (6--03)
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).
CHARGING THE BATTERIES
1. Drive the machine to a flat, dry surface in a
well-ventilated area.
2. Turn the machine power off and set the
parking brake if your machine has this
option.

MAINTENANCE
FOR SAFETY: Before leaving or
servicing machine, stop on level
surface, and turn off machine.
3. Lift up the solution tank to get access to the
batteries.
NOTE: The solution tank must be empty.
4. Check the water level in all the battery cells.
00879
5. If the level is low, add just enough distilled
water to cover the battery plates. DO NOT
