PolIshING ANd usING The T ool
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	profilers	 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-680	 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 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	Double	 End	Wrench 	
(19mm/22mm)	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, keyways and bearings, which may 
not be immediately evident.
 AIR VAl Ve 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 
pressure of 85 PSI, with the lever 
pointing	 to	the	 ON	 position.	 This	will	
produce	 4,000	RPM.	Do	not	 try	to	vary	
the speed.  The tool works best at full 
  CAUTION!  
						

							12
throttle	only.	Do	not	 attempt	 to	exceed	 the	recommended	 speed	by	
excess	 pressure.	 This	will	significantly	 shorten	the	life	of	the	 tool.	
When storing the tool overnight, disconnect from the air supply and 
open the valve.
    helPful hINT : 
•	 Air valve lever should be opened and closed slowly to allow 
the tool to accelerate and decelerate during all applications. 
Rapid acceleration and deceleration can wear out the ball 
bearings prematurely.
   helPful hINT : 
•	 Using a Filter Regulator System is 
Recommended
 fIl TeR/ReGulAT oR sysTem 
Having a Filter/Regulator helps prevent 
pressure drops when using a large 
volume of air, so you can set the 
pressure to the tools at 85 PSI, while the main system can run at 
125 PSI. The F/R unit will also remove any water from the air supply 
while	 also	filtering	 the	air	of	contamination	 down	to	five	 microns.	 By	
only using aluminum and brass after the F/R unit, you are eliminating 
any rust and contamination from getting into the air tools. 
The Alpha
® F/R Manifold System comes in two sizes, 53 CFM & 106 
CFM	 and	three	 adapter	 blocks:	3/8”,	1/2”	and	3/4”,	 and	is	designed	
for installation at the point of use.  All F/R manifolds are custom-
configured	 to	a	clients	 specific	 needs	and	are	available	 through	our	
distributor network, and via our website. 
 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	an	internal	 Silencer	
System. When the polisher is operated correctly at 85 PSI, the sound 
level emitted should be less than 80 dBA. The internal Silencer 
System is also used to maintain a constant back pressure inside the 
tool, to prevent the rotor assembly from exceeding the max speed 
of the bearings; this helps prevent the polisher from exceeding the 
recommended 4,000 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 rust inhibitor oil dripping 
on the work piece. 
Tools sent in for repair, where the body gasket or silencer is removed 
or	modified,	are	not	covered	under	our	Limited	Warranty.
 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 Tip:
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 light downward hand pressure.  Applying excessive 
force or pressure may damage the vanes and could shorten the life 
of the tool.
