Operations

How This Machine Works

The Chariot® is a battery powered, self-propelled, hard
floor scrubber intended for commercial use. The
appliance applies a cleaning solution onto a hard floor,
scrubs the floor with a brush, and then vacuums the
soiled water back into the recovery tank.

The machine's primary systems are the solution
system, scrub system, recovery system, and operator
control system.

The function of the solution system is to store cleaning
solution and deliver it to the scrub system. The solution
system consists of the solution tank, strainer, metering
valve and solenoid valve. The solution tank stores
cleaning solution (water and detergent) until it is
delivered to the scrub system. The strainer protects the
valves from debris. The solenoid valve automatically
prevents solution flow unless the scrub brush is turned
on and the machine is being propelled.

The function of the scrub system is to scrub the floor.
The disk scrub system consists of one rotary type disk

scrub brush, motor, scrub deck skirt and lift actuator.
The brush scrubs the floor as the motor drives the
brush. The brush drive hub allows the scrub brush to
follow irregularities and changes in the floor without
loosing contact with the floor. The scrub deck skirt
controls the cleaning solution on the floor so that the
squeegee can pick it up.

The function of the recovery system is to vacuum the
soiled water back into the recovery tank. The recovery
system consists of the squeegee, vacuum motor, float
ball, recovery tank. The squeegee wipes the dirty
solution off the floor as the machine moves forward.
The vacuum motor provides suction to draw the dirty
solution off the floor and into the recovery tank. The
float ball filter protects the vacuum fan from debris and
foam. The recovery tank stores the dirty solution.

The function of the operator control system is to control
the direction and speed of the machine. The directional
control system consists of the direction control drive
reset switch, throttle pedal, emergency stop/brake
switch, steering wheel, propel controller, and drive
wheel. The directional control drive reset switch signals
forward or reverse direction and make s sure the
operator is on the platform before machine will propel.
The controller interprets signals from the throttle pedal
to command the drive wheel to propel or slow the
machine. The steering wheel points the drive wheel in
the direction desired by the operator . The parking brake
automatically engages when the operator stop the
machine. The emergency stop/brake can be used to
hold the machine on slopes.

The cylindrical scrub system consists of two cylindrical
brushes, motor, side squeegees, and lift actuator. The
two counter rotating brushes scrub the floo r , driven by a
single motor. The brush deck “floats” with constant
brush pressure. The side squeegee s keep the cleaning
solution within the brush deck width, allowing the main
squeegee to pick the solution up.

8. BATTERY DISCHARGE INDICATOR

Indicates the charge level of the batteries.
The indicator will be illuminated if the batteries have a sufficient charge. A slow, continuous flash indicates the
batteries require charging.

The Battery Lockout function will activate when the batteries are low.
Once active, the LED status indicator will begin to flash slowly and the controller will inhibit the scrub motor and
water solenoid. The vacuum and drive remain functional. The “vacuum only” selection (position ‘B’) can be
used to vacuum up any remaining water. Return the unit to the charging station and charge the batteries.

NOTE: Continuing usage may damage the batteries.

When the machine is left overnight with less than a full charg e, the display ma y initially indicate a full ch arge. It
will also indicate a full charge if the batteries are disconnected, then reconnected. After a few minutes of
operation the indicator will give the correct charge level.

9. HOUR METER

Records the number of hours the machine has been in scrubbing operation. This information is useful in de te r­mining when to service the machine.

Operations

3. Measure the chemical into the solution tank. Liquid
chemicals should be added to the solution tank
after filling with water. Dry chemicals should be
thoroughly mixed before being added into solution
tank. Commercially available, high alkaline floor
cleaners, are suitable for use in the solution sys­tem.

Normal Scrubbing

Plan the scrubbing pattern in advance. The longest
track is around the perimeter of the area to be cleaned.
For efficient operation, the runs should be the longest
possible without turning, stopping, or raising or
lowering scrub deck/squeegee.

In order to achieve the best possible results, the area
which is to be cleaned should be swept before scrub­bing. Large debris, strings and wire must be removed to
prevent being caught in brushes or squeegee.

If the machine is allowed to stand in neutral with the
scrub deck down, the solutions flow stops and brush
motor stops. If either forward or reverse travel is
selected, the solution flow will continue in the same
setting and the scrub brush motor will continue once
movement of machine begins. Overlap the brush path
and avoid transporting over previously cleaned areas.

To Begin Scrubbing

When operating the machine around people, pay
close attention for unexpected movement. Use
extra caution around children.

Flammable liquids and/or reactive metals can
cause explosions or fire! Do not pick up.

1. St and on the operator plat form. Throttle pedal must
be in neutral position.

2. Turn machine power on.

3. Press the Drive Reset / Directional Control Switch,
selecting the desired travel direction.

Maintenance

Batteries (Wet Cell)

The batteries provide the power to operate the
machine. The batteries require regular maintenance to
keep them operating at peak efficiency.

The machine batteries will hold their charge for long
periods of time, but they can only be charged a certa in
number of times. To get the greatest life from the
batteries, charge them when their charge level reaches
25% of a full charge. Use a hydrometer to check the
charge level.

Do not allow the batteries to remain in a discharged
condition for any length of time. Never expose a
discharged battery to temperatures below freezing.
Discharged batteries will freeze causing cracked
cases. Do not operate the machine if the batteries are
in poor condition or if they have a charge level below
25% (specific gravity below 1.155).

When servicing machine, avoid contact with
battery acid.

Batteries emit hydrogen gas. Explosion or fire can
result. Keep sparks and open flame away. Keep
covers open when charging.

Wear eye protection and protective clothing when
working with batteries.

Keep all metallic objects off the top of the batteries, as
they may cause a short circuit. Replace worn or
damaged cables and terminals.

Check the electrolyte level in each battery cell before
and after charging the batteries. Never add acid to the
batteries, use distilled water . Do not allow water level to
fall below the battery plates. Portions of plates exposed
to air will be destroyed. Do not overfill. Keep plugs
firmly in place at all times.

Not all batteries require maintenance. AGM
batteries are maintenance free. Do not attempt to
remove sealed caps from AGM batteries. Warranty
is void if caps are removed from AGM battery.

Charge batteries in a well ventilated area.

Battery Maintenance

1. When cleaning the batteries, use a solution of
baking soda and water. Do not allow the cleaning
fluid to enter the battery cells, electrolyte will be
neutralized.

2. Maintain the proper electrolyte level in each battery
cell. If a cell should accidentally overflow, clean
immediately.

3. Wipe off the top of the batteries at least once a
week.

4. Test battery condition with a hydrometer at least
once a week.

5. Ensure that all connections are tight and all
corrosion removed.

6. Every 4 to 6 months, remove the batteries from the
machine and clean the battery cases and battery
compartment.

Checking Battery Specific Gravity

Use a hydrometer to check the battery specific gravity .

CHECKING GRAVITY

a. Hydrometer Battery
b. Battery

NOTE: Do not take readings immediately after adding

distilled water, if the water and acid are not thoroughly
mixed, the reading may not be accurate.

Check the hydrometer readings against this chart.

1.120 DISCHARGED

NOTE: If the readings are taken when the batt er y
electrolyte is any temperature other than 80°F (27°C),
the reading must be temperature co rr ect ed .

To find the corrected specific gravity reading when the
temperature of the battery electrolyte is other than 80°F
(27°C): Add (+) to the specific gravity reading 0.004 (4
points), for each 10°F (6°C) above 80° (27°C). Subtra ct
(-) from the specific reading 0.004 (4 points), for each
10°F (6°C) below 80°F (27°C).

Charging Batteries

When servicing machine, avoid contact with
battery acid.

Batteries emit hydrogen gas. Explosion or fire can
result. Keep sparks and open flame away. Keep
covers open when charging.

Wear eye protection and protective clothing when
working with batteries.

Charge batteries in a well ventilated area.

Use a 36 volt, 20 amp maximum output DC charger
which will automatically shut off when the batteries are
fully charged.

1. Stop the machine in a clean, well ventilated area
next to the charger.

2. Turn “OFF” machine.

FOR SAFETY: Before leaving or servicing machine;
stop on level surface, turn off machine and remove
key.

3. Remove rear cover, unplug batteries from
machine, unlatch battery tray and pull out to
expose batteries.

Batteries emit hydrogen gas. Explosion or fire can
result. Keep sparks and open flame away. Keep
covers open when charging.

4. Check the electrolyte level in each battery cell.
Before charging, add just enough distilled water to
cover the plates. After charging is complete, add
just enough distilled water to bring up the level to
the indicator ring. If the water level is too high
before charging, normal expansion rate of the elec­trolyte may cause an overflow resulting in a loss of
battery acid balance and damage the machine.

Carbon
Brushes

End Cap

If armature commutator is grooved, extremely pitted or not
concentric, the motor will need to be replaced or sent to a
qualified service center.

Inportant:
These brushes wear quicker as the length shortens due to
increased heat. Spring inside brush housing will damage
motor if brushes are allowed to wear away completely.

Periodically check the length of the carbon brushes. Replace
both carbon brushes when either is less tan 3/8" (9.5mm)
long.

RecoveryTDank Float Shut-off

When water is no longer being vacuumed from the floor
and the vacuum fan is operating, the ball float has
engaged. The vacuum motor will not vacuum water
with recovery tank full. The recovery tank must be
drained.
