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 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.

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.

1. KEY SWITCH

Controls the power for machine functions.

To turn the machine power on, rotate key clock-

wise.

To turn the machine off, rotate key counterclock-

wise.

When the key is turned on the battery symbol will

flash once and stay on continuously.

2. EMERGENCY STOP/BRAKE SWITCH

This safety feature is designed to cut all power to

the machine at any time and apply parking brake.

To shut the machine power off, push the

Emergency Stop Switch, this will also engage the

parking brake and cause the machine to stop

immediately.

To reset the machine, rotate the switch clockwise.

3. DIRECTIONAL CONTROL / DRIVE RESET

SWITCH

This safety feature is designed to ensure safe

engagement of propel drive. Each time the

machine power is turned on, or each time an

operator steps on to the platform, the Drive Reset

Switch must be pushed before machine will propel.

The switch controls the direction of travel of the

vehicle. The lighted arrow on the switch indicates

direction of travel.

To travel forward, press the top of the switch.

To travel in reverse, press the bottom of the switch.

Operations

4. THROTTLE PEDAL

Controls the speed of the vehicle within the speed control setting selected. Pressing the pedal causes the

machine to travel in the direction selected by the Directional Control Switch.

To increase speed, increase pressure on the pedal.

To decrease speed, decrease pressure on the pedal.

5. HORN BUTTON

The horn is activated by pressing the horn button.

6. STEERING WHEEL

The steering wheel turns the front wheel causing the machine to change direction.

7. SPEED CONTROL

Controls the maximum speed of the machine. There are two settings, slow and fast.

To change speed, rotate the dial to either slow or fast position. The slow position is to the left (counterclock-

wise), fast to the right (top position).

The throttle pedal will always regulate the speed between 0 and maximum.

Operations

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 charge, the display may initially indicate a full charge. It

will also indicate a full charge if the batteries are disconnected, then reconnected. After a few minutes of

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 scrub-

bing. 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.

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

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.

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°C): Add (+) to the specific gravity reading 0.004 (4

points), for each 10°F (6°C) above 80° (27°C). Subtract

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].”

Maintenance

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.

There are 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.

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.

Finished Floors

Polypropylene is a general-purpose scrub brush with

stiff bristles. Polypropylene works well for maintaining

routed tile 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 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 re-

coating.

The scrub brushes should be checked before each

days work for wire, string, wear and damage.
