HOW THIS MACHINE WORKS
The Chariot iExtract® is a battery powered, selfpropelled Carpet Extractor intended for commercial
use. The machine is designed to apply a cleaning
solution onto carpeted floor, sweep and scrub the
carpet with two counter-rotating brushes, then
vacuum 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 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 pump switch controls the
cleaning solution flow to the spray jets/accessory
port.
The function of the scrub system is to sweep and
scrub the carpet and lift and groom the carpet pile.
The scrub system consists of two cylindrical
brushes, motors, hopper, lift actuator, and controls.
The brushes scrub the carpet as the motors drive
the brushes. The counter-rotating action of the
brushes picks up debris and throws it into a
removable hopper. The actuator switch controls the
lift actuator and brush motors to lower the deck and
turn the motors on, or raise the deck and turn the
motors off. The brush motors will automatically turn
off when the throttle pedal is in neutral.
The function of the recovery system is to vacuum the
soiled water back into the recovery tank. The
recovery system consists of the v a cuum shoes,
vacuum motors, float ball filter, recovery bag and
controls. The vacuum shoes extract the dirty solution
from the carpet as the machine moves forward. The
vacuum motors provide 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.
3-3
86037880 CHARIOT EXTRACTOR 11/18/09
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, speed control switch,
drive reset switch, emergency stop/brake switch,
steering wheel, propel controller, drive wheel and
operator presence pedal prior to Serial Number(11*).
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 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.

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.
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.
4. Replace solution tank cover.
Flammable materials
can cause an
explosion or fire. Do not use flammable
materials in the tanks.
MACHINE OPERATION
NORMAL SCRUBBING
Plan the scrubbing pattern in advance.
For efficient operation, the runs should be the
longest possible without turning, stopping, or raising
or lowering scrub deck. The longest track is around
the perimeter of the area to be cleaned and a
collapsing rectangle pattern is most efficient.
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.
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. When
forward travel is resumed, the solution flow and the
scrub brush motors will continue. Overlap the brush
path and avoid transporting over previously cleaned
areas.

BATTERIES
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.
MAINTENANCE-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.
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

NOTE: If the readings are taken when the battery
electrolyte is any temperature other than 80°F
(27°C), the reading must be temperature corrected.
To find the corrected specific gravity reading when
the temperature of the battery electrolyte is other
than 80°F (27°): Add (+) to the specific gravity
reading 0.004 (4 points), for each 10°F (6°C) above
80° (27°C).
Subtract (-) from the specific reading 0.004 (4
points), for each 10°F (6°C) below 80°F (27°C).

SCRUB HEAD
The dual cylindrical scrub head is designed to
sweep and scrub the carpet. The brushes, turning in
a counterclockwise rotation, pick up the debris and
throw it into a removable hopper, and raise the pile
of the carpet, giving it a lush groomed appearance.
MAINTENANCE
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. 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 PerformAlert
bristles.
SCRUB BRUSH REMOVAL
The scrub brushes are removed from the sides of
the machine. The front is removed from the right
side and the rear is removed from the left side.
1. Unscrew knob on brush door but do not remove.
2. Pull out on top of door until lip on door clears
brush head.

MAINTENANCE-SCRUB DECK
SCRUB DECK ADJUSTMENT
Scrub deck adjustment consists of three 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. The third is to make the contact patterns
on the floor the correct width. Proper adjustment is
obtained when the contact patterns of the brushes
on the floor show two equal 1-1.5 inch (25-38 mm)
rectangles the width of the brushes. The rectangles
should be parallel to each other.
TESTING, ADJUSTMENT OF INDIVIDUAL
BRUSHES
1. Move the machine to an unfinished area of hard
floor to avoid marking carpet.
2. With pump off, lower scrub head to floor. Allow
brushes to run for approximately 30 seconds. 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.
1"-1 1/2"
Tapered
Pattern
CORRECT BRUSH PATTERN
Even and
Parallel
Pattern
INCORRECT BRUSH PATTERNS
Uneven
Pattern
ADJUSTMENT OF INDIVIDUAL BRUSHES
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 hex socket head screws on the
end of the housing.
3. Loosen the jam nut on the jackscrew and rotate
the jackscrew to move the motor assembly up or
down as needed.
4. Tighten the 3 hex socket head screws.
5. Tighten the jam nut on the jackscrew.
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. Links should be adjusted to equal lengths. 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.
ADJUSTING BRUSH PRESSURE
Changing the brush pressure is accomplished by
adjusting the take-up nuts on the deck counterbalance spring. To increase brush pressure or
pattern width, loosen the nuts. To decrease brush
pressure or pattern width, tighten the nuts.

MACHINE TROUBLESHOOTING-
CONTROLLER FAULT CODES
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.
