  CAUTION!
Lubricating the stone cutter before and during work is not needed. Exces-
sive 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 to be used with this stone cutter. Old or worn 
compressors, which emit oil through the air lines, can significantly shorten 
the life of the tool.
  helPful hInT: 
•  Air  throttle  lever  should  be  pressed  and  released  slowly  to 
allow the stone cutter 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  i s 
Recommended
 fIl TeR/ReGula ToR sysTem 
Having  a  Filter/Regulator  (See  Fig.  4) 
helps  prevent  pressure  drops  when 
using  a  large  volume  of  air,  so  you 
can  set  the  pressure  to  the  tools  at  85 
to  90  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. 
Alpha
®  recommends the F/R Manifold 106 CFM for use with the PSC-150 
stone  cutter.  (Part  Nos.  1030-0023/1030-0024).  All  F/R  manifolds  are  
available through our distributor network, and via our website.

This valve lets you adjust the flow of water to the blade.  When storing the 
stone cutter overnight, open the valve and drain all water from the supply 
hose and tool.

The new 1/2” x 15’ flexible air hose has a 3/8” Male NPT threaded fitting 
to connect to your air supply.  This hose is composed of a premium hybrid 
polymer  that  allows  the  hose  to  avoid  kinking  and  remains  flexible  down 
to -40°F.

maintenance and usage Tip:
•  Do not leave the stone cutter submersed in water. This could 
expose the inner moving parts to moisture, which will shorten 
the life of the stone cutter.
•  Excessive  force  or  impact  to  the  spindle  may  result  in 
premature failure of gears and/or bearings, which may not be 
immediately evident.
 sounD leVel  (heaRInG PRoTeCTIon musT be W oRn)
To  comply  with  OSHA  Occupational  Noise  Exposure  Standard  Number 
1926.52, this tool is equipped with an internal Silencer System. When the 
tool is operated correctly at 90 PSI, the sound level emitted should be less 
than  91.3  dBA.  The  internal  Silencer  System  is  also  used  to  maintain  a 
constant back pressure inside the tool; this helps prevent it from exceeding 
the recommended 8,500 RPM.  The exhaust deflector for this stone cutter 
also helps to reduce the noise level by venting the exhaust air.

Height  adjustment  is  possible  if  you  need  to  raise  the  PSC-150  body  to 
control the depth of cut. 
1.  Loosen the clamping lever (Part 
No.  3001-0057)  and  lift  the 
main body. When you reach the 
desired  cutting  depth,  tighten 
the adjustment lever.

set the tool to the desired angle, follow the steps below. 
1. Loosen both the screws of the front and rear using the Hex. wrench.
2. Tilt the PSC-150 to the desired angle. 
3. When the cutting angle is decided, re-tighten the screws.

StrAIGHt CuttING
1. One-pass  cutting  can  be  performed  on  all  thickness  materials  using 
the PSC-150. (2cm, 3cm & 4cm thickness materials)
NOTE:  ALPHA® ALWAYS RECOMMENDS STEP-CUTTING 
2.  Adjust the amount of water-flow to cool the blade and remove the waste.
3.  Set the base plate on the work piece and align to the cutting mark on 
the base plate to cut line on the material. 
4.  Press  the  throttle  level  and  allow  the  stone  cutter  to  attain  full  speed 
before starting to cut. 
5.  Advance  the  stone  cutter  slowly  allowing  the  blade  to  do  the  work, 
keeping the base plate flat on the stone and the cut mark in line with 
your cut line. (See Fig. 14)

  WARNING!
Support the sink cutout area; sinkhole cutout piece may drop to the 
floor at the end of cutting application, if not supported.  
1.  Support the sink cutout area prior to cutting; otherwise, the work piece 
may drop to the floor at the end of the cutting application. 
2.  Use  the  Alpha
®  Contour  Cutting  blade  only.  Application  with  inferior 
blades may cause damage to the stone cutter. 
3.  Plunge Cut into the material until the base of the stone cutter makes 
flush  contact  with  the  material,  then  proceed  to  cut  the  bowl  cut-out 
following the step-cutting process.  
4.  Do not force the stone cutter during the cutting application. Allow the 
blade to cut at its own pace. Excessive force may damage the stone 
cutter.
