 aI r  ValV e   le V er  
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 4,000 
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.  This  will  significantly 
shorten the life of the tool.
 WaT er  C on T rol ValV e  
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.

T
o  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 87 PSI, the sound 
level emitted should be less than 80 dBA. The internal Silencer Sys-
tem is also used to maintain a constant back pressure inside the tool; 
this helps prevent it 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 lubricant dripping on the work piece.  The new Silencer 
System is designed to allow small particle of contamination and dust 
to pass through, however if your air supply has particles larger than 
1mm you will need to clean out the Silencer.    
						

							12
maintenance and usage Tip:
The  Silencer is located on the rear of the polisher under the air and 
water  fittings.   A  clogged  Silencer  would  be  indicated  by  a  loss  of 
power or lower RPM’s from the tool.  To clean the Silencer remove 
the air and water fittings, use a small screwdriver or pick to remove 
the hard plastic silencer and blow it out with compressed air from the 
outside (flat side of silencer).  Reinstall the Silencer with the recessed 
side of the Silencer toward the tool, the Silencer should fit into the 
encase tightly, leaving a flat surface on the outside of the tool.  
  WARNING!
 
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. 
m

aintenance and  u sage 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  disc  and  could  shorten  the  life 
of the tool.
 WaT er   su PP ly  hose  
This  hose  may  be  connected  to  any  garden  hose.    The  hose  is 
composed of a special material to avoid kinks.  Replacements are 
available should the hose become damaged,  Part No. 133229.
