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

losing 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.

86398220 Operators Manual - Chariot-2 iScrub 20

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

operation the indicator will give the correct charge level.

9. HOUR METER

Records the number of hours the machine has been in scrubbing operation. This information is useful in deter-

mining when to service the machine.

Operations

Vacuum only mode

This mode is used for picking up solution only. The brush and water will both be up and off. In

this mode the machine will propel at fast speed. The squeegee is lowered and the vacuum will

come on.

Double Scrub cleaning (with chemical metering on equipped models)

This mode is used for putting down solution and scrubbing without picking it back up. The

squeegee is set manually by connecting the two double scrub support cables. In this mode the

machine will propel at a slow speed. The scrub deck will lower. The solution will flow. The brush

and water will shut off when the machine is in neutral. They will resume when propelling is

resumed.

Light cleaning with chemical metering

Chemical dilution rate to be set by chemical metering selection switch.

Deep cleaning with chemical metering

Chemical dilution rate to be set by chemical metering selection switch.

Finish removal (on select orbital models)

This mode is used for removing floor finish without the use of chemicals. In this mode the

machine will propel at a very slow speed. The 'floating' scrub deck and squeegee are in the

down position. The water will flow while propelling and will automatically shut off in neutral.

Water flow rate is controlled by the flow shut-off valve. The vacuum will draw water into the

recovery tank.
