2. Consider work area environment
Do not expose power tools to rain. Do not use power tools in damp or wet locations
without GFCI protection. Keep work areas well lit. Do not use the tool in presence of
ammableliquidsorgases.
3. Guard against electric shock
Prevent body contact with grounded surfaces. For example: pipes, radiators, ranges,
and refrigerator enclosures; use grounded outlets.
4. Keep children and visitors away
Do not let visitors contact tool or extension cord. All visitors should be kept away from
work area. Keep out of reach of children.
5. Tool Storage
When not in use, tools should be stored in a secure dry location. A locked storage area
or high shelf out of children’s reach is ideal.
6. Do not force the tool
It will do the job better and be safer at the rate for which it was intended.
7. Use the right tool
Do not force a small tool or attachment to do the job of a heavy-duty tool. Do not use
the tool for purposes it is not designed for – (for example – do not use circular saw for
cutting tree limbs or logs.)

parts. Rubber gloves and non-skid footwear are recommended when working outdoors.
Wear protective hair covering to contain long hair.
9. Use safety glasses
Always wear safety glasses and if necessary, a face or dust mask also.
10. Do not abuse the electrical cord
Never carry the tool by the electrical cord or pull it to disconnect from receptacle. Keep
the electrical cord away from heat, oil and sharp edges.
11. Secure workpiece
Use clamps or a vise to hold workpiece rather than using your hands.
12. Do not overreach
Keep proper footing and balance at all times.
13. Maintain tools with care
Keep tools sharp and clean for better and safer performance. Follow instructions for
lubricating and changing accessories. Inspect the electrical cord periodically and
if damaged, have it repaired by authorized service facility. Inspect extension cords
periodically and replace if damaged. Keep handles dry, clean and free from oil and
grease.

3. Hold the polisher tightly at start-up.
Failure to do so may cause an injury due to high impact at initial start up.
4. Stop using the polisher immediately when noticing any malfunctions or any
suspicious abnormal noises.
Turn the power switch OFF and contact your dealer or Alpha Professional Tools for
repair.
5. Handle the polisher with care.
If you accidentally drop the polisher, do not use it until checking that it is not cracked,
deformed, or damaged in any way.
6. Donotpourwateroranyliquidsontoorinsidethepolisher.
It may cause electric shocks.
7. Do not hold the polisher in a vice.
8. Do not touch any rotating parts.
Never touch the polishing disc of the polisher during operation with your hands.
9. Donotleavethediscwhilespinningonthebench,oororsurfaceofyour
workpiece.
It may cause an accident or injury.

WARNING!
10. Attach the backer pad and polishing disc correctly by following the procedure
in this instruction manual.
Attaching the polishing discs incorrectly may cause an accident.
11. Observe any suspicious abnormal noises when a polishing disc is attached for

cause an accident.
ABOUT DOUBLE INSULATION
This polisher is designed with double insulation. Two insulations are used between the
conductor and the outer body of the polisher. An Electric Polisher with the double insulation
highlyimprovessafetyfromelectricshocks.Donotattachorreplaceunspeciedpartsand
do not assemble incorrectly. This may cause the insulation to malfunction.

PREPARATION BEFORE OPERATION
1. GFCI Information.
– Since the Alpha®Wet Polisher is designed with double insulation, an in-line GFCI is
provided as a standard accessory. For your safety and to prevent possible electric
shocks, it is strongly advised to test the GFCI on a regular basis.
Note: The GFCI must be used for your safety when this polisher is
used anywhere in a damp environment, when used with water, or
when it is used on metal plates, steel frames or platens.
Never attach a damaged extension cord to the polisher.
Note: Use the appropriate extension cord as referred below. The
table shown below is for 115V use. For 220V use, the maximum
length of a cord may be twice as long as the cord for 115V.
LAWS AND REGULATIONS OF NOISE LEVELS
Please observe local laws and regulations regarding noise level in order to avoid disturbing
surroundingareas.Installasoundproofwallifrequiredtocomplywiththelocallawsand

GROUND FAULT CIRCUIT INTERRUPTER (GFCI)
A Ground Fault Circuit Interrupter is built in line with the power supply cord.
The GFCI goes OFF when water enters inside the tool’s housing preventing the operator
from electric shocks.
When the GFCI goes OFF, this could be the result of water entering the polisher
housing.

air inside the motor cover through the air vents.
2. Re-connect power supply and press the GFCI reset button. The polisher is ready
to start working once the reset button is pressed down.
TESTING IN-LINE GFCI UNIT (Before Each Use Of The Polisher)
1. Connect polisher to a single phase AC power supply.
2. Verify that the indicator lens shows red (indicating output voltage).
3. Press the test button to verify that the red in the indicator lens disappears.
4. Press the reset button to verify the red indicator is visible.
5. The GFCI is now ready for use.

MAINTENANCE
DAILY:
Before servicing polisher turn the switch off and disconnect from power supply.
1. Before daily start-up inspect polisher, power cord, GFCI, and water feed system for
loose hardware and/or damage.
2. If damage has occurred, repair affected areas before use.

PERIODIC:
Carbon brushes wear out over time base on the polisher usage. If a carbon brush is worn
out, it may cause the motor to malfunction or fail to run. Whenever the length of the carbon
brush reaches the wear limit, replace with a new set.
NOTE - To maintain even wear, both brushes should be replaced at the same time.
The carbon brushes in this polisher are located underneath the Rear Cover (Part # 52)
as shown in Figure 13.
