120 VOLT MACHINES
Instructions for connection to the power
supply and the electrical ground.
This product must be grounded. If it should
malfunction or breakdown, grounding provides a path
of least resistance for electric current to reduce the
risk of electrical shock. This product is equipped
with a cord having an equipment-grounding conductor
and grounding plug. The plug must be inserted into
an appropriate oulet that is properly installed and
grounded in accordance with all local codes and
ordinances.
WARNING:Improper connection of the
equipment-grounding conductor can
result in a risk of electric shock. Check
with a qualified electrician or service
person if you are in doubt as to whether
the outlet is properly grounded. Do not
modify the plug provided with the
product. If it will not fit the outlet, have a
proper outlet installed by a qualified
electrician.
This product is for use on a nominal 120 volt circuit
and has a grounding attachment plug that looks like
the plug illustrated in Figure 1. Make sure that the
product is connected to an outlet having the same
configuration as the plug. No adaptor should be
used with this product.

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 contrac
tor.
WARNING: Have worn, cut or damaged
cords 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.
WARNING: If you use an extension
cord, use an extension cord with
minimum wire size 12 AWG. Do not use
an extension cord longer than 50 feet.
Do not join two extension cords.
This machine is shipped with the handle assembly
separate from the base. Assemble as follows:
1. Loosen but do not remove the two square head knobs
on the rear of the machine.
2. Insert the handle tube between the frame and handle
clamp until it bottoms.
3. Tighten the two square head knobs to secure the
handle tube.
4. Connect cord set to the motor pigtail.
Install a pad and the machine is ready to operate.

How To Install the Pads
WARNING: Always remove the electrical
plug from the electrical outlet
before installing or changing the
pad.
The pad driver assembly is on the bottom underside of
the machine. The pad holder holds the pad in position.
The machine has a screw-on pad holder. To install the
pad, follow this procedure:
1. With the handle locked in the operating position, tilt
burnisher back on the handle until the underside of the
burnisher is fully exposed. (See figure 2).
2. Remove the retainer from the pad holder by unscrewing
(turn counterclockwise).
3. Remove the center scored circle from a pad.
4. Place pad on pad driver.
5. Be sure pad is properly centered on the driver.
6. Reinstall the retainer on the pad holder until pad is
tightly secured (turn clockwise).
mable materials and vapors.
Do not use with or near flammables, such as: gasoline,
grain dust, solvents and
thinners.
CAUTION:Allowing the machine to run
without moving forward or
backward can cause serious
damage to the floor surface.
Make sure the machine is always moving when the pad is
rotating.
NOTE: You must have training in the operation of
this machine before you use it.
How To Start/Stop The Machine
The normal position of this burnisher, with the pad stationary, is tilted back with the pad off the floor.
1. Remove cable completely from cable hook.

2. With the handle in operating position and the power
cable plugged into the proper outlet, depress the
interlock button (1) and squeeze the levers beneath
the handle grips (2). (See figure 3).
3. As the motor reaches full speed (1-2 seconds), bring
the pad into contact with the floor.
NOTE: Make sure you hold the handle with both
hands.
How To Operate the Machine
For best results, use a clean pad and change frequently
as pad loads up. A motor overload could result from a
dirty, loaded pad. If the built-in circuit breaker trips, turn
off the machine, wait five (5) seconds, then depress the
reset button on the circuit breaker. Change the pad.
The Circuit Breaker
A circuit breaker is used to protect the motor. If the motor
draws high current, the circuit breaker will stop the motor.
The circuit breaker reset button is on the rear of the motor
cover. Push the reset button to reset the circuit breaker.
If the motor continues to stop, consult an authorized
service person.
This burnisher will give you many years of trouble-free
service provided it is given proper care. Throwing,
dropping, bumping across the thresholds and other
misuse may result in a damaged unit and invalidate the
warranty. When storing your burnisher, always remove
the pad.
Pads can be cleaned by washing in warm water and a mild
detergent, rinsing, and hanging up to dry.
The pad driver spindle bearings should be re-lubricated
once a year. Do not over lubricate. Allow grease to enter
bearings slowly.
NOTE: Do not store the machine resting on the
pad driver, the pad driver will warp and cause
vibration.
Inspections and Repairs

authorized repair location once a year for the maintenance
inspections.

before doing any repairs or
maintenance to the machine.
WARNING: Do not operate this machine
unless it is completely assembled.
WARNING: Keep all fasteners tight. Keep
adjustments according to
specifications.
Maintenance of the Motor
This machine has a DC permanent magnet motor that
uses a commutator, carbon brushes, and a rectifier.
Keep the machine clean. It will need fewer repairs and
have a longer life. Remove or blow dust from the motor
frequently.
The Indicator Light
This machine has an indicator light that illuminates
when the brushes are worn. The commutator must be
inspected each time the brushes are changed. After
the brushes have been replaced two times, have the
commutator surface turned. Have an authorized
service person make the repairs.
How to Check the Commutator and the Carbon
Brushes
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.
To check the commutator and the carbon brushes,
follow this procedure:
1. Remove the two top screws of the motor cover.
2. Remove the cover.
3. Pull back each spring and pull the brush out of the
holder. Keep the lead wire connected.
4. Turn the pad driver and look at the part of the
commutator that the brushes touch.
5. Take the machine to an authorized repair location if
you see any of the following conditions:
1.) Small holes in the surface of the commutator. See Figure 4 "A".
2.) Uneven color. Look for an even dark brown
color. Clean areas or very dark areas
indicate a problem. See Figure 4 "B".
3.) High mica. The mica insulation must be
lower than the commutator bars. See
Figure 4 "C".
6. Replace all four carbon brushes if any carbon
brush is shorter that 7/16 inch. To replace the
carbon brushes in the motor, follow this procedure:

1.) Remove the screws. Replace the brush and
lead. Install the screw.
2.) Use a hook to pull the spring out of the way.
Install the brush into the slot in the same
position as the original brush (the shunt wire
on the brush should be located above the
brush spring.) Put the spring into position
on the end of the brush. The lead must not
prevent free movement of the brush in the
holder.
3.) Install the motor cover.
Rectifier
If the machine has been adjusted, and still blows fuses
and runs at half speed, the rectifier may be damaged.
Take the machine to an authorized repair location to
have a Clarke Technology authorized repair person
replace the rectifier.
