SPECIAL FEATURE  
TheAlpha® Air Polisher was designed with human engineering for operator comfort.  
It comes equipped with a silencer which reduces the level of noise as well as  
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.

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.  
7
 
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.
