the area well lit.
4. KEEP CHILDREN AND VISITORS AWAY. All visitors should be kept a safe
distance from the work area. Keep out of reach of children.
5. DON’T FORCE TOOL. It will do the job better and safer at the rate for

10. ALWAYS SECURE WORK PIECE. Use clamps or a vise to hold work. It’s
safer than using your hand and it frees both hands to operate tool.
11. DON’T OVERREACH. Keep proper footing and balance at all times.
12. DISCONNECT TOOLS WHEN NOT IN USE. Always disconnect tool before

14. MAINTAIN TOOLS WITH CARE. Keep tools clean at all times for best
and safest performance. Follow instructions for lubricating and changing
accessories. Keep handles dry, clean and free of oil or grease. Inspect
moving parts for alignment and binding as well as for breakage and improper
mounting.
15. AVOID ACCIDENTAL STARTING. Don’t carry a “connected” tool, or make
adjustments, or change discs without making sure the air valve is in the off
position to prevent the flow of air.
16. USE ONLY RECOMMENDED ACCESSORIES. The use of any accessories
other than what is listed or recommended for this particular tool may be
hazardous.
17. KEEP HANDS AWAY FROM ALL MOVING PARTS.
18. USE SIDE HANDLES. Supplied with tool for control and safety.
19. USE RECOMMENDED GRINDING WHEELS ONLY. Do not use
conventional abrasive grinding wheels with this tool. Only use diamond

guiding the cold exhaust air away from an operator during the polishing process.
This feature also eliminates excess lubricant dripping on the work piece. Portions
of the body design are made with synthetic materials and covered with rubber to
prevent fatigue and coldness to hands.

this manual. Please take time to familiarize yourself with the features of the tool.
Be sure to fill out the registration card enclosed, and mail it back to the distribution
center today.
AIR FITTINGS AND PRESSURE
Your new Alpha® polisher is designed for continuous duty polishing. When select-
ing your compressor, buy a system
which can handle a constant flow
of air. We recommend that you
purchase a heavy duty two stage
cast iron type unit. The system
should include a regulator and a
moisture trap.

•
•
Each tool requires: 87 PSI (0.6Mpa / 6 bars); however the range of 85-90 PSI
is acceptable.
(6 kg / cm2) of air pressure and 15 CFM (420 l / min.) of air flow.
We suggest a minimum of 5 HP air compressor with a holding tank of 50
cubic feet (1,400 l) capacity for one tool.
•
•
Air hose fitting is 1/4” BSPP
The use of heavy duty 3/8” (10mm) hose is suggested for all lines.
LUBRICATION (Lube Oil is used to protect the tool from rusting when not in use)
PROPER CAREAND LUBRICATIONARE IMPORTANT FACTORS IN THE USEFUL
LIFE OF THIS TOOL.
At the end of each workday, 2-3 drops of lubricant oil, solvent free oil (included with
each polisher) should be placed in the air inlet at the base of the tool. Rotate the
spindle counter clockwise, by hand 3-4 revolutions. Reinstall the air hose and run
the tool for a minute or two. (Replacement containers of oil may be purchased from
Alpha Professional Tools® Part # AIR-008.)
Maintenance and Usage Tip
Automatic oilers are not recommended: the volume, grade, and composition of oil
used may cause premature failure. In-line air dryers are recommended to extend
the life of the tool. Old or worn compressors, which emit oil through the air lines,
can dramatically shorten the life of the tool.
SPINDLE SIZE
The Alpha® AIR-658 air polisher features a 5/8”-11 size spindle. This tool has
been designed for portable/shop production and uses all modern accessories.
It is very important that you do not run anything heavier than the recommended
accessories on this machine. A drop of oil should be applied to the outside
threads whenever attachments are changed to facilitate removal and prevent
rust. A 22mm Spindle Wrench is provided to assist in changing accessories.
Maintenance and Usage Tip
• Do not leave the tool submersed in water. This could expose the inner
moving parts to moisture, which will shorten the life of the tool.
• Do not leave threaded accessories (backer pads, core drill bits, profilers) on
the spindle of tool for extended periods of time; this may result in making it
difficult to remove these accessories.
• Excessive force or impact to the spindle may result in premature failure of
gears and/or bearings, which may not be immediately evident.

AIR VALVE LEVER
The valve lever controls the flow of air through the tool.
It has two positions- ON or OFF. Run the tool at the
recommended range of 85-90 PSI, with the lever pointing
to the ON position. This will produce 3,500 RPM. Do not
try to vary the speed. The tool works best at full throttle
only. Do not attempt to exceed the recommended speed
by excess pressure.
WATER CONTROL VALVE
This valve lets you adjust the flow of water through the spindle. It may be used to
shut off the water entirely when changing discs. When storing the tool overnight,
open the valve and drain all water from the supply hose and tool.
SILENCER / MUFFLER
To comply with OSHA Occupational Noise Exposure Standard Number 1926.52,
this polisher is equipped with a Silencer. When the polisher is operated correctly
at 87 PSI, the sound level emitted should be 80 dBA. The Silencer is also used
to maintain a constant back pressure inside the tool; this helps to prevent it from
exceeding the recommended 3,500 RPM.
The exhaust hose for this tool also helps to reduce the noise level by venting the
exhaust air and residual air-line, thus eliminating the risk of excess lubricant drip-
ping on the work piece.
Silencers should be replaced when dirty or clogged to provide optimum performance.
A spare silencer is included with the purchase of a new polisher.
Maintenance and Usage Tip:
• Operating the tool at a pressure that exceeds the recommended operating
specifications or without the silencer may result in premature failure of the
tool.
• The silencer, Part # 658-52, should be replaced when it no longer allows air
to flow freely. This is indicated by a dark, shiny appearance.
WARNING!
Tools sent in for repair, where the silencer is removed or blown out,
are not covered under our Limited Warranty!

SPLASH / SAFETY GUARD
For operator comfort and safety, a splash guard has been provided. The guard
should remain in place for all grinding and polishing operations.
C-SHAPE HANDLE / REVERSIBLE SIDE HANDLE
The C-Shape handle: During use with Alpha® Core Bits and Alpha® Profilers,
use of the “C-Shape” handle is recommended. C-Shape handle will allow
operator to have more control and ease of operation during these applications.
Reversible Side Handle: Attach the handle into the threaded socket on either
the left or right side of the tool. A locknut is slipped onto the threads to keep the
handle safely in position.
Maintenance and Usage Tips:
Do not apply more force or pressure than the force created by the weight of the
polisher itself. The polishing discs are designed to work properly under lightweight
pressure. Applying excessive force or pressure may damage the disc and could
shorten the life of the tool.
WATER SUPPLY HOSE
This hose may be connected to any garden hose using a clamp. The hose is com-
posed of a special material to avoid kinks. Replacements are available should the
hose become damaged, Part # 133229.
