DANGER: Using a machine with a damaged power cord could result in an electrocution. Do not use the machine if the power cord is damaged. To prevent damage to the power cord, do not let the brush touch the power cord when the machine is running. Always lift the power cord over the machine. Do not use the electrical cord to move the machine.

DANGER: Electrocution could occur if maintenance and repairs are performed on a unit that is not disconnected from the power source. Disconnect the power supply before changing the brush or accessories or attempting any maintenance or service.

Maintenance and repairs must be done by authorized personnel.

WARNING: Operating a machine without observing all labels and instructional information could result in injury or damage. Read all machine labels before attempting to operate.

Clarke Technology distributor for assistance.

WARNING: To prevent electrical shock, do not use this machine on wet surfaces. Protect the machine from rain, Keep the machine in a dry building. Always clean the machine with a clean dry cloth.

CLARKE TECHNOLOGY Operator's Manual 577 Carpetmaster Page 3

HOW TO PREPARE THE MACHINE FOR OPERATION

WARNING: To prevent electric shock, do not vacuum liquids or wet surfaces with this machine.

The Model 577 has five brush settings (1). The adjustment lever

(2) is at the rear of the machine. See Figure 1.

To set the brush height, do the following:

1. Place your foot behind one wheel.

NOTE: Do not push the handle release lever.

2. Pull back on the handle a little.

3. With your other hand, pull the adjustment lever.

4. Put the adjustment lever in the "High" setting.

5. Move the adjustment lever toward the "Low" setting.

6. When the brush comes in contact with the carpet, push the adjustment lever in the detent.

NOTE: Do not set the brush too low. Shag carpets are generally best cleaned by the brush in the highest setting.

CAUTION: Be careful when cleaning long shag, the carpet can go around the brush, and slow or stop the brush.

120 VOLT MACHINES

INSTRUCTIONS FOR CONNECTION

TO THE POWER SUPPLY

AND THE ELECTRICAL GROUND

The machine must be connected to the electrical ground to protect the operator from electric shock. The machine has an approved power cord with three conductors and a plug with three terminals. Connect the plug to a receptacle that has three holes and is connected to the electrical ground.

For maximum protection against electric shock, use a circuit that is protected by a ground fault circuit interrupter.

The green (or green and yellow) conductor in the cord is the ground wire. Never connect this wire to any terminal other than the ground terminal.

This machine uses a 120 volt AC 60 cycle electrical circuit.

Make sure you have the correct frequency and voltage before connecting the power cord to an outlet. The machine has a plug as shown in Figure 4. If a receptacle connected to the electrical ground as shown in Figure 4 is not available, have one installed by an electrical contractor. Do not use an adapter.

WARNING: To prevent possible electric shock, protect the machine from rain. Keep the machine in a dry building.

WARNING: To prevent possible electric shock, always use a 3-wire electrical system connected to the electrical ground.

For maximum protection against electrical shock, use a circuit that is protected by a ground fault circuit interrupter. Consult your electrical contractor.

WARNING: Do not cut, remove or break the ground pin. If the outlet does not fit the plug, consult your electrical contractor.

WARNING: Have worn, cut, or damaged cords and plugs replaced by an authorized service person.

EXTENSION CORDS

Use only an approved extension cord with three conductors, a plug with three terminals, and a connector body with three holes. The machine has a power cord with wire size 14

AWG (AWG means American Wire Gauge).

WARNING: If you use an extension cord, use an extension cord with minimum wire size 16 AWG. Do not use an extension cord longer than 50 feet. Do not join two extension cords.

Maintenance Of The Vacuum Motor

This machine uses a universal motor that has a commutator and carbon brushes. The commutator and carbon brushes must be checked every six months, or 600 hours of operation, whichever comes first.

WARNING: Electrical inspections must be made by a person authorized to do maintenance.

Electrical repairs must be made by a person authorized to make electrical repairs.

WARNING: To prevent electrical shock, always remove the electrical plug from the electrical outlet before doing any repairs or maintenance to this machine.

How To Check The Commutator and The Carbon Brushes

To check the commutator and the carbon brushes, follow this procedure:

1. Remove the screws that hold the motor baffle. The motor baffle is at the rear of the machine.

2. Remove the baffle.

3. Remove the wire clip mounting screw and the grounding mounting screw.

4. Remove the wire nuts.

5. Remove the vacuum motor mounting screws.

6. Remove the motor from the tank.

7. Inspect the commutator. Take the machine to a Clarke Technology Authorized Repair Location if you see any of the following conditions: a. Small holes in the surface of the commutator. See figure 15A b. Uneven color. Look for an even dark brown color.

Clean areas or very dark areas indicate a problem.

See figure 15B c. High mica. The mica insulation must be lower than the commutator bars. See figure 15C

8. Remove the carbon brush assemblies and check the carbon brushes. Replace both carbon brush assemblies if either brush is shorter than 3/8 inch. If either brush is shorter than

1/2 inch, order replacement brushes. Be ready to replace both carbon brushes earlier than the normal inspection time.

9. Install the motor, the motor baffle, and the fasteners.

WARNING: The machine must be tested for electrical safety after electrical repairs are made.

NOTE: For safe operation have your machine checked by a Clarke Technology

Authorized Repair Person every 12 months. Always use Clarke Technology replacement parts.
