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 scrub deck side squeegees control the cleaning
solution on the floor so that the squeegee can pick it
up. The brush pressure switch controls the motors
and lift actuator to turn the motors on and lower the
deck, or turn the motors off and raise the deck. The
brush pressure switch also controls the down
pressure on the scrub deck.
The machine's primary systems are the solution
system, scrub system, recovery system, and
operator control system.
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 and controls.
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 bag. The float ball filter
protects the vacuum fan from debris and foam. The
recovery bag stores the dirty solution.
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 and controls. 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 solution control switch controls the
amount of cleaning solution delivered to the scrub
system by controlling the amount of time the pump is
on.
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 switch, throttle pedal, operator presence
pedal, speed control switch, drive reset switch,
emergency stop/brake switch, steering wheel, propel
controller, and drive wheel. The directional control
switch signals forward or reverse direction. The
controller interprets signals from the throttle pedal to
command the drive wheel to propel or slow the
machine. The drive reset switch is to make sure the
operator is on platform before machine will propel.
The operator presence pedal is to make sure the
operator keeps both feet safely on platform while
driving. 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 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, lift
actuator and controls. 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 one touch/brush switch controls the motors
and lift actuator to turn the motors on and lower the
deck, or turn the motors off and raise the deck. The
brush pressure switch controls the down pressure
on the scrub deck.
The scrub plus system consists of two cylindrical
type brushes, motors, scrub deck side squeegees,
hopper, lift actuator, and controls. 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.

MACHINE OPERATION
FILLING SOLUTION TANK
NORMAL SCRUBBING
FOR SAFETY: Before leaving or servicing
machine; stop on level surface, turn off machine
and remove key.
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.
1. Turn the machine power off.
2. Remove solution cover.
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.
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 140ꢀ F (60ꢀC) to
prevent damage to the tank.
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.
4. 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.
NOTE: Read the chemical manufacturers
recommended proportion instructions.
5. Replace solution tank cover.
Flammable materials
can cause an
explosion or fire. Do not use flammable
materials in the tanks.

MACHINE OPERATION
TO STOP SCRUBBING
DOUBLE SCRUB
1. BASIC AND CYLINDRICAL
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.
Raise the scrub deck, turn off scrub
brushes.
To double scrub, make the first pass over the
surface being cleaned with the squeegee up,
vacuum off, the solution on, Aqua-Mizer removed
and brushes down. This allows 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
squeegee down and again the solution and brushes
on will further loosen soil. The additional application
of solution will further assist the difficult cleaning job.
Raise squeegee, turn off vacuum.
DELUXE
Press the one-touch switch (#1) on the
control panel. The brush motors will stop
and the scrub deck will rise to the park
position. After 15 seconds the squeegee
will raise, and 15 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: When using machine, go slow on
inclines and slippery services.
FOR SAFETY: Before leaving or servicing
machine: stop on level surface, turn off machine

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.

SQUEEGEE BLADES
TO REMOVE SQUEEGEE ASSEMBLY
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.
1. With the squeegee in the up position, turn key
switch “OFF”.
2. Disconnect vacuum hose from squeegee and
loosen knob on left side of squeegee lifting
carrier.
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.
3. Pull squeegee assembly from the lifting carrier.
4. Inspect or repair as necessary and reinstall.
TO REPLACE OR ROTATE REAR SQUEEGEE
BLADES
Check both the front and rear squeegee blades for
damage, wear, and adjustment each day in the pre-
run check. Change the front blade if it is torn or has
an uneven edge. Change the rear blade if it is less
than 1/2 the original thickness.
1. With the squeegee in the up position, turn key
switch “OFF”.
FOR SAFETY: Before leaving or servicing
machine; stop on level surface, turn off machine

ADJUSTING SQUEEGEE
2. Remove the squeegee assembly from the
machine. Unlatch and remove blade retainer
strap and remove squeegee blade.
Adjusting the squeegee is a two-part process. First,
the 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.
3. Rotate the squeegee to new edge position or
replace as required. Each blade has four new
edge positions.

MAINTENANCE-SCRUB BRUSHES
SCRUB BRUSHES
FINISHED FLOORS
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.
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
finish.
UNCOATED FLOORS
Aggressive Grit is a nylon fiber impregnated with
silicone carbide grit. It grinds away stain, soil, and
removes surface material.
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.
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.
Black Pads (Stripping) 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.
Polypropylene is a general-purpose scrub brush
with stiff bristles. Polypropylene works well for
maintaining concrete, wood and tile floors.
The scrub brushes should be checked before each
days work for wire, string, wear and damage.

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. The larger debris
which might catch under the squeegee is collected
in the hopper. Water is allowed to drain out the
hopper into the squeegee path where it is recovered
from the floor.

The brushes should wear evenly side to side if
properly adjusted. Scrub brushes should be
exchanged front to back every 50 hours to ensure
even wear since the rear brush contacts the floor
with more force. It is not necessary to rotate end for
end since swapping front to back puts the brushes in
the opposite rotation, as well as balancing wear.
Scrub brushes should be replaced as a set when
bristle length wears to height of yellow

DUMPING HOPPER
ADJUSTMENT OF INDIVIDUAL BRUSHES
The removable hopper is located behind the rear
scrub brush. If the hopper becomes full, it will not
accept any more debris. Loosen knob on left side
squeegee and swing open. Remove the hopper by
sliding it out from the operator’s left side of the
machine. The hopper can then be dumped from the
top. Flush the hopper clean with running water.
The brush pattern is adjusted from the motor side
only of both brushes.
1. Determine if motor end is to be moved up or
down to balance the pattern.
2. Loosen the 3 allen head screws on the end of
the housing.
SCRUB DECK ADJUSTMENT
3. Loosen the jam nut on the jack screw and rotate
the jack screw to move the motor assembly up
or down as needed.
Scrub deck adjustment consists of two types of
adjustments. The first is to insure the individual
brushes make the same width pattern end to end.
Any tapered brush pattern should be adjusted out.
The second is to make the pattern of equal width
between front and rear brushes. Unequal patterns
are caused by the scrub deck not being parallel to
the floor. Proper adjustment is obtained when the
contact patterns of the brushes on the floor show
two 1” rectangles the width of the brushes. The
rectangles should be parallel to each other.
4. Tighten the 3 allen head screws.
5. Tighten the jam nut on the jack screw.
6. Re-test and readjust as necessary.
LEVELING THE SCRUB HEAD
Leveling the cylindrical head is accomplished by
adjusting the lower links that attach the deck to the
frame. To increase pattern width on rear brush,
loosen lock nuts and shorten the lower links by
screwing the rod into the threaded ends. To
increase pattern width on front brush, lengthen the
lower links by screwing the rod out of the threaded
ends. After adjustment, be sure to tighten lock nuts.
TESTING, ADJUSTMENT OF INDIVIDUAL
BRUSHES
1. Move the machine to an unfinished area of floor
to avoid marking finish.
2. With water valve off, lower scrub head to floor.
Allow brushes to run until automatic shut off
occurs. It may be necessary to repeat this step
in the same location until a good mark can be
seen on the floor. This can be accomplished by
touching lightly the throttle pedal to restart the
scrub deck without moving the machine.
3. Raise the scrub deck and note the brush
patterns on the floor. There should be two
rectangles with parallel sides. If the pattern is
tapered, proceed as follows.

Scrub head must be in the up position before
loading.
NOTE: When transporting the machine on a trailer
or in a truck, in addition to using tie-downs, be
sure to set the parking brake, and block the tires to
prevent the machine from rolling.
MACHINE TIE-DOWNS
There are two tie points located at front and each side
of foot box frame and two at the front side of frame.
Tie-down devices must be of the proper type and
strength. The combined strength of all tie-downs must
be strong enough to lift two times the weight of the
machine. Tie-downs must be positioned to prevent
the machine from moving forward, backward, or either
side to side. Use all four corners of the machine with
the tie-downs running out opposite directions. Tie-

PROPEL CIRCUIT BOARD TROUBLESHOOTING
Curtis 1228 LED DIAGNOSTICS- Basic and Cylindrical
During normal operation, with no faults present, the status LED is steadily on.
If the controller detects a fault, the status LED provides two types of information.
First, it displays a slow flash (2 Hz) or a fast flash (4 Hz) to indicate the
severity of the fault. Slow-flash faults are self-clearing; as soon as the fault is
corrected, the vehicle will operate normally. Fast-flash faults (“.” in Table 2) are
considered to be more serious in nature and require that the key switch be cycled
to resume operation after the fault is corrected.
After the severity indication has been active for 10 seconds, the status
LED flashes a 2-digit fault identification code continuously until the fault is
corrected. For example, code “1,4”—low battery voltage—appears as: one LED flash, followed by a pause,
then 4 LED flashes, and then repeats.
