86037810 Chariot iVacuum 9

Operations

How This machine Works

The Chariot® iVacuum™ is a battery powered, selfpropelled, carpet vacuum intended for commercial use.

The appliance vacuums debris and dirt from the carpet and collects it in a disposable bag.

The machine's primary systems are the brush system, vacuum system, and operator control system.

The function of the brush system is to brush the carpet.

The brush system consists of two cylindrical type brushes, motor, brush deck, and controls.

The front brush turns clockwise when viewed from the right side of the machine. The rear brush turns counterclockwise. Both brushes work to agitate the carpet and to route the debris up in to the central vacuum nozzle.

The function of the vacuum system is to vacuum dirt and debris into the vacuum bag. The recovery system consists of the vacuum nozzle, vacuum motor, cloth vacuum bag and paper vacuum bag. The vacuum nozzle captures the dirt off the floor as the machine moves forward. The vacuum motor provides suction to draw the dirt into the vacuum bag. The vacuum bag stores the dirt.

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(17*). 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.

Operations

Normal Vacuuming

Plan the vacuuming 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 or stopping.

In order to achieve the best possible results, the area which is to be cleaned should be picked up before vacuuming. Large debris, strings and wire must be removed to prevent being caught in brushes.

If machine is allowed to stand in neutral with the vacuum deck down for more than 2 seconds, the brush motor stops. If either forward or reverse travel is selected, the brush motor will continue once movement of machine begins. Overlap the brush path and avoid transporting over previously cleaned areas.

Recommended Path

Maintenance

Batteries (Wet Cell Only)

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.

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 battery cell. If a cell should accidentally overflow, clean immediately.

3.

Wipe off the top of the batteries at least once a week.

4.

Test battery condition with a hydrometer at least once a week.

5.

Ensure that all connections are tight and all corrosion removed.

6.

Every 4 to 6 months, remove that batteries from the machine and clean the battery cases and battery compartment.

Checking Battery Specific Gravity

Use a hydrometer to check the battery specific gravity.

Charging 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.

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°): 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).

Charge batteries in a well ventilated area.

Use a 36 volt, 20 amp maximum output DC charger which will automatically shut off when the batteries are fully charged.

1.

Empty recovery tank.

2.

Stop the machine in a clean, well ventilated area next to the charger.

3.

Turn "OFF" machine.

FOR SAFETY: Before leaving or servicing machine; stop on level surface, turn off machine and remove key.

4.

Unplug the machine from the battery pack.

Remove front cover. Disconnect recovery hose from "Y" tube. Raise recovery tank and verify prop rod latch is safely engaged.

Batteries emit hydrogen gas. Explosion or fire can result. Keep sparks and open flame away. Keep covers open when charging.

5.

Check the electrolyte level in each battery cell.

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.

26 86037810 Chariot iVacuum

Brush Deck Adjustment

Brush deck adjustment consists of one adjustment to make the pattern of equal width between front and rear brushes. Unequal patterns are caused by the deck not being parallel to the floor. Proper adjustment is obtained when the contact patterns of the brushes on the floor show two rectangles the width of the brushes.

The rectangles should be parallel to each other.

Adjustment Deck Levelness Testing

1. Move the machine to an area of hard floor to avoid damaging carpet.

2. Lower brush 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 brush deck and note the brush patterns on the floor. There should be two rectangles with parallel sides. The width of the front and rear rectangle should be equal.

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.
