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 brushes, 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, pump,
valve. The solution tank stores cleaning solution (water
and detergent) until it is delivered to the scrub system.
The strainer protects the pump from debris. The valve
automatically prevents solution flow unless the scrub
brushes are 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 two rotary type disk
scrub brushes, motors, scrub deck skirt and lift
actuator. The brushes scrub the floor as the motors
drive the brushes. The brush drive hubs allow the
scrub brushes to follow irregularities and changes in
the floor without loosing contact with the floor. The
scrub deck skirts control the cleaning solution on the
floor so that the squeegee can pick it up.
The scrub deck side squeegees control 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 filter, recovery bag. The squeegee wipes the dirty
solution off the floor as the machine moves for ward.
The vacuum motor provides suction to draw the dirty
solution off the floor and into the recovery bag. The
float ball filter protects the vacuum fan from debris and
foam. The recovery bag 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 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 steps off the
platform. The emergency stop/brake can be used to
hold the machine on slopes.
The scrub plus system consists of two cylindrical type
brushes, motors, scrub deck side squeegees, hopper,
lift actuator. The cylindrical scrub head is designed to
eliminate debris that may be caught in the squeegee
while scrubbing. Water is applied to the first scrubbing
brush turning in a clockwise rotation when viewed from
the right side of machine. The first brush scrubs dirt
and debris between the brushes. The second
scrubbing brush, turning in a counter clockwise
rotation, picks up debris and throws it into a removable
hopper. Water is allowed to drain out the hopper into
the squeegee path where it is recovered from the floor .

Filling Solution Tank
FOR SAFETY: Before leaving or servicing
machine; stop on level surface, turn off machine
and remove key.
1. Turn the machine power off.
2. Remove solution cover.
3. Fill the solution tank with clean water, leaving
enough room for the required amount of cleaning
solution. The solution tank capacity filled to fill inlet
is 25 gallons (95 liters). The water must not be hotter than 140° F (60°C) to prevent damage to the
tank.
4. Measure the chemical into the solution tank. The
solution cover is also a 2 oz. (60 ml) measuring
cup. 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.
NOTE: Read the chemical manufacturers
recommended proportion instructions.
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 for more than 2 seconds, the
solutions flow stops and brush motors stop. If either
forward or reverse travel is selected, the solution flow
will continue in the same setting and the scrub brush
motors will continue in their same setting once
movement of machine begins. Overlap the brush path
and avoid transporting over previously cleaned areas.
5. Replace solution tank cover.
Flammable materials can cause an explosion or
fire. Do not use flammable materials in the tanks
86317500 CHARIOT SCRUBBER 21
Operations
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. Stand on the operator platform. 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.
4. Position the function control knob to the desired
operation. The brush motors will start, the scrub
deck will lower, the solution will begin to flow, the
squeegee will lower to the floor and the vacuum
motors will start.
5. Drive machine forward to begin scrubbing.
NOTE: Shut machine off immediately if water or foam
is expelled from the machine.
NOTE: Solution flow is automatically shut off when
brush motors stop. When brush motors are
activated, flow automatically resumes.
Priming Pump
If the solution system has gone dry or has been unused
for a period of time, it may be necessary to follow the
pump priming procedure.
1. Fill solution tank.
2. Loosen, but do not completely remove the strainer
bowl. Solution should flow out of the strainer. If it
does not, check the strainer screen inside the solution tank. Insure it is clear of debris. Ti ghten the
strainer bowl.
3. Disconnect the squeegee hose from the recovery
dome.
4. Begin normal scrubbing. Solution flow should
begin within 2 minutes.
5. Connect squeegee hose to recovery dome.
22 86317500 CHARIOT SCRUBBER
Operations
To Stop Scrubbing
1. Rotate the function knob to either transport position. The brush motors will stop and the scrub deck
will rise to the park position. After 10 seconds the
squeegee will raise, and 10 seconds later the vacuum motor will turn off. This delay is to clear the
vacuum hose of recovered solution.
2. Allow the throttle pedal to return to neutral.
3. Turn machine power off.
FOR SAFETY: Before leaving or servicing
machine: stop on level surface, turn off machine
and remove key.
Double Scrub
For floors which are heavily soiled or have thick accumulations of floor finish, may not clean sufficiently with
one pass. In these cases it will be necessary to double
scrub.
Rotate the knob to the double scrub position.
Make the first pass over the surface being cleaned with
the squeegee up, vacuum off and the solution on. For
best results also remove the Aqua-mizer™, this will
allow the solution to stay in contact with the soil while
loosening the surface accumulation with the brushes.
Allow time for the first application to stay in contact with
the floor. Length of time between the first and second
pass depends on amount of accumulation and the type
of chemical being used. A second scrubbing with the
function knob in one of the normal scrubbing modes will
lower the squeegee and will keep the solution on and
brushes down to further loosen soil. The additional
application of solution will further assist the difficult
cleaning job.

BATTERIES (WET CELL ONLY)
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 certain
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).
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.
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.
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 that batteries from
the machine and clean the battery cases and
battery compartment.

Squeegee Blades
The front squeegee blade allows solution to pass
through channels in the blade into the squeegee
assembly while maintaining vacuum to provide lift. The
front blade has four wear surfaces and can be rotated
for extended life. The front blade should not require
regular replacement under normal use.
The rear blade wipes the floor to a near dry condition. It
is important the rear blade be in good condition to
properly do its job. As with the front, each squeegee
blade assembly has four wear surfaces for extended
service.
Check both the front and rear squeegee blades for
damage, wear , and adjustment ea ch day in th e pre-r un
check. Change the front blade if it is torn or has an
uneven edge. Change the rear blade if it is le ss th an 1/
2 the original thickness.
Adjusting Squeegee
Adjusting the squeegee is a two-part process. First, th e
squeegee assembly must have correct pitch in order for
the squeegee blade to have the same deflection at
each tip as well as the center. The rod on the
squeegee linkage controls the pitch adjustment. The
second adjustment is the deflection. Knobs on each
end of the squeegee control this.

Scrub Brushes
There are four different types of brushes available to
cover applications from cleaning heavily soiled floors to
polishing. A pad driver is also available to take
advantage of the many cleaning pads on the market.
Please refer to the following to assist in selecting the
proper brush or pad for the work at hand.
Uncoated Floors
Aggressive Grit is a nylon fiber impregnated with
silicone carbide grit. It grinds away stain, soil, and
removes surface material.
Mild Grit is a less aggressive silicone carbide grit
suitable for cleaning medium soil conditions. Advantages are faster ground speed than nylon bristles on
light solid applications.
Polypropylene is a general-purpose scrub brush with
stiff bristles. Polypropylene works well for maintaining
concrete, wood and tile floors.
Finished Floors
Nylon bristles are used in a variety of applications on
coated or uncoated surfaces.
White Pads (Polishing) are used for dry polishing to
achieve a high-gloss appearance, or surface washing
on highly polished or burnished floors.
Red Pads (Buffing) are used for light-duty scrubbing.
When used with a mild detergent they will provide
surface cleaning without removing the finsh.
Blue Pads (Scrubbing) are used for heavy-duty
scrubbing and light stripping. The blue pads remove
less finish than brown stripping pads, yet will remove
black marks, stains and dirt.
Black Pads (Strippin g) are used for easy and complete
removal of old floor waxes/finishes. They will quickly
remove ground in dirt, black heel marks, and spills.
When used with the proper stripper, this pad leaves the
floor clean and ready for finishing.
The scrub brushes should be checked before each
days work for wire, string, wear and damage.
