Operators Manual - Chariot-2 iScrub 20

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 makes 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 floor, driven by a
single motor. The brush deck “floats” with constant
brush pressure. The side squeegees keep the cleaning
solution within the brush deck width, allowing the main
squeegee to pick the solution up.

To Begin Scrubbing

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

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.

Lorsque vous utilisez la machine en présence de
gens, portez une attention particulière aux mouvements inattendus. Soyez plus prudent, surtout en
présence d’enfants.

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

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 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.

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.

L’entretien n’est pas nécessaire pour toutes les
batteries. Les batteries AGM ne nécessitent pas
d’entretien. N'essayez pas d'enlever les bouchons

Configuring the IC650 Charger Using a USB Flash Drive
Using the Delta Q software, USB storage drives can be pre-programmed to certain charger configuration.
To use the USB port, follow these steps:
1. Insert the USB flash drive at any time, except during a charge cycle. Stop the charge cycle by removing AC
power or the DC connection to the batteries. The charger will power the USB port from the remaining AC
connection.
2. If there is enough disk space, the charger will write charge tracking data to the drive. The Fault/Error/USB
Indicator will flash green during reading and writing.
3. If the drive contains compatible configuration files, the charger will load them.
4. The IC650 Charger will briefly reset.
5. Remove the drive when the Fault/Error/USB Indicator is solid green.

Figure 4, Insert the USB flash drive to begin the reprogramming process. When complete, the Fault/Error/USB
Indicator will be solid green as shown.

Troubleshooting
If the alarm indicator flashes amber, note the error code and retry the update. If there is no response to inserting
the USB drive when the charger is being used off-board, check that AC power is available and connected. If the
charger is installed on-board, ensure that the charger either has AC power and / or batteries are connected.

Confirming a Software Update
After using a USB flash drive to update the charger firmware, the update can be confirmed by reviewing the .txt file
written to the flash drive by the charger. It will be located in the folder labelled ‘syslog’ (e.g.
F:\CHARGER\RESP\serialno\syslog\00000000.txt).
Open this file using a text editing program such as Notepad or Microsoft Word. If the update has been successful,
near the end of the text you will see a description resembling “SM Task: Successful upgrade at
Major[001].Minor[991].Build[000]variant[008].”

Charge Tracking Data
All IC650 Chargers record data such as amp hours returned, charge cycle completion or interruption, and the
charge profile being used. This data can be very useful in vehicle or machine diagnostics.
To retrieve this data, follow these steps:
1. After a charge cycle is complete, or the charger is disconnected from the battery pack, insert a USB flash drive
with at least 2MB of free space into the IC650 Charger’s USB hose port. The charger will automatically begin
to downlad the data, shown on the Fault/Error/USB Indicator with a flashing green light.
If you plan to download data from a large number of chargers, having more free space on your USB flash drive is
recommended. If you want to update the software on only some of your chargers, it is recommended that you use
separate USB flash drives for updating and downloading charge tracking data.

Figure 5, Insert the USB flash drive to begin the charge data download process. This step can be completed using
the same USB flash drive programmed to update the charger’s software. The process is completed when the USB
indicator is solid green, and no longer flashing.
2. The downloading process is complete when the Fault/Error/USB Indicator is solid green. The USB flash drive
can be removed from the charger.

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.

Polypropylene is a general-purpose scrub brush with
stiff bristles. Polypropylene works well for maintaining
routed tile floors.

Scrub Brush-Orbital
The orbital machine is designed for use on finished
floors. The pad driver is fixed to the machine and
accepts various pad types depending on the work to be
performed.

directly to pad driver. Damage to pad driver may
result.

Scrub Brush-Cylindrical
There are different types of brushes available to cover
applications from cleaning heavily soiled floors to
polishing.
White (Soft)

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.
Blue Pads (scrubbing) are used for heavy scrubbing
and light top scrubbing. The blue pads remove black
marks, stains and dirt. The blue pad may also remove
some floor finish.
Black pads (top scrubbing) are used to remove ground
in soil and the top layers of floor finish to prepare for recoating.

The scrub brushes should be checked before each
days work for wire, string, wear and damage.
