SPECIAL FEATURES
The Alpha® 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.

CONNECTION FITTINGS
The air and water hose ttings on the back of this tool are BSPP
(British standard parallel pipe or “G” thread). These ttings have
parallel threads and seal off on the at surface on the bottom of
the thread. This type of tting is usually supplied with an “O”ring or
sealing ring which we replaced with the silencer.

WARNING!
Trying to convert either tting to an American standard pipe thread
(NPT), which is tapered, will crack the end-case and is not covered
under warranty.

AIR PRESSURE AND VOLUME
The recommended air pressure for this tool is 87 PSI (6 BARS),
however, the range of 85 to 90 psi is acceptable. Any pressure over
90 PSI will exceed the max speed rating of the rotor bearings caus-
ing them to overheat and lock up.
The most important factor in running this tool is the volume of air being
supplied to the tool. The volume is the air consumption needed to run
this tool at a constant speed under light downward hand pressure.
The volume is measured in CFM (cubic foot per minute (ft3/min). You
need a minimum of 15 CFM per tool.
When choosing a compressor to run an AIR-658 polisher, we rec-
ommend a rotary screw type with a minimum of a 5hp motor/15-20
CFM and a 60 gallon tank, per tool. So if you want to run four tools,
you will need a compressor with a 20hp motor capability of 80+
CFM and an 80 to 100 gallon storage tank. It is also very important
to keep your air cool, dry, and clean, so look for a compressor with
a refrigerated dryer and high-efciency lter built in or purchase
a separate air dryer and lter unit rated for your compressors
CFM.
LUBRICATION (Lube oil is used to protect the tool from rust-
ing when not in use)
PROPER CAREAND LUBRICATIONARE IMPORTANT FACTORS
IN PREVENTING THIS TOOL FROM RUSTING ON THE INSIDE
WHEN NOT IN USE.
At the end of each workday, 2-3 drops of lubrication oil with rust inhibi-
tor (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 second
or two to distribute the oil and mist the inside of the tool. (Replace-
ment containers of oil may be purchased from Alpha® Professional
Tools Part No. AIR-008).
10
Lubricating the tool before and during working is not needed. Ex-
cessive oil will turn to a tar-like substance inside the tool, causing
the vanes to stick in the rotor and slow the tool down. This is the
reason we do not recommend automatic oilers be used with this
tool. Old or worn compressors, which emit oil through the air lines,
can signicantly shorten the life of the tool.
POLISHING AND USING THE TOOL
This tool and the Alpha® accessories approved for use with this tool
are designed to be used under light downward hand pressure. You
need to allow the polishing pads, core bits, and prolers to do their
job. Applying excessive downward pressure to the tool will cause
the vanes to wear out in the middle and fail prematurely.
SPINDLE SIZE
The Alpha® AIR-658 air polisher features a 5/8”-11 spindle. This
tool has been designed for portable/shop production and uses all
modern accessories. It is very important that you do not run any-
thing 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, prolers) on the spindle of tool for extended periods of
time; this may result in making it difcult 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.
