BEFORE USE
  DANGER!
Before using the machine, check the following items.  In particular, check items 1 to 5 before 
plugging the power supply cord into the power outlet.
1. Check the working voltage.
–  Be sure the voltage specified on the nameplate is the voltage available at the 
power outlet. If the machine is used with higher voltage than specified, the 
motor will burnout.  Any attempts to do so may damage the tool and/or cause an 
accident.
2.  Make sure the ON/OFF switch is off.
–  If you plug in the power supply cord without realizing that the switch i\
s ON, the 
machine will start and may cause an accident.
–  Make sure the switch is in the OFF position before plugging the cord in \
the power 
outlet.
3.  Inspect the protective cover.
– Do not remove the cover.  It will protect you if the saw blade breaks. 
– Be sure to firmly attach the saw blade or any optional accessory.
4.  Inspect the saw blade.
– Check if you have a specified blade.
– Never use cracked, chipped, or any damaged blades.
–  Follow the procedures specified in the instruction manual to properly attach 
applicable accessories.
5.  Check the power outlet.
–  When the plug of the power supply cord is easily pulled out of the power outlet, 
the outlet should be replaced.  For such tasks, consult an electrician.  If the power 
outlet is used on a continuous basis, it may overheat and cause accidents. 
6.  Perform test runs.

  WARNING!
1. Before turning the switch ON, make sure the rotating parts are not touch\
ing    
anything. If the switch is turned ON while they are in contact with anyt\
hing    
else, the blade may get damaged and it may cause injuries.
2. When a new blade is attached and the switch is turned ON, keep your body\
    
well away from the exposed sides of the tool for a moment until the mach\
ine    
reaches its full speed.
3. It is very dangerous to perform cutting operations using cracked, chipped or damaged 
blades. Before starting cutting operations, keep the tool away from anyo\
ne nearby. Be 
sure to perform a few test runs to check whether there are any abnormali\
ties.
  ABOUT DOUBLE INSULATION
This machine is designed with double insulation. Two insulations are used between the 
conductor and the outer body of the machine.  An Electric Machine with the double insulation 
highly improves safety from electric shocks.  Do not attach or replace unspecified parts and 
do not assemble incorrectly. This may cause the  insulation to malfunction.   
   LAWS AND REGULATIONS OF NOISE LEVELS
Please observe local laws and regulations regarding noise level in order to avoid disturbing 
surrounding areas.  Install a soundproof wall if required to comply with the local laws and 
regulations. 
 INSTRUCTIONS FOR INSTALLING THE FELT STRIPS ON THE
    AWS-125/AWS-225 BASE PLATE:
1.  Wipe base plate with a clean rag to remove 
any dirt or residue.
2.  Peel  off  film  from  the  pressure  sensitive 
adhesive on the enclosed felt strips.

 INSTALLATION OF WATER ATTACHMENT
1.  Remove the wing screw and washer for 
adjusting the cutting depth. 
 (See Figure-6)
2.  Raise cutting depth so there is room 
between the body and the base plate. 
(See Figure-6)
3.  Insert the plastic nozzle on the water-feed assembly behind the height adjustment 
slide. Make sure that the water valve bracket (Part No. 133094) is in \
front of the slide. 
If your blade is already installed, the plastic nozzles should be positi\
oned so that each 
nozzle directs water spray onto each side of the blade. (See Figure-7 & Figure-8)
4.  Align the water valve bracket with 
the wing nut hole and insert wing 
bolt. 
 (See Figure-9)
5.  Adjust the height of the blade and securely tighten the wing bolt.

  CAUTION!
Allow the saw blade to do the work, applying excessive forward pressure \
to the tool will slow 
down the RPM’s and burn up the motor, which voids the limited warranty of the tool.
This tools should only be used for cutting on a horizontal surface.
Be sure to follow daily maintenance before and after each use.
 
 OPTION 1: FREE-HAND CUTTING
If you are cutting stone or tile less than 20 mm (3/4”) thick, the cut can be done in 
one pass (allow saw blade to do the work).
2. If you are cutting stone or tile more than 20mm thick you will need to m\
ake the 
cut in two passes.  Adjust the height to 15-20mm for the first pass, then adjust 
the saw blade below the stone for the second pass ( allow the saw blade to do 
the work).
3. Adjust the amount of water-flow to cool the blade and remove the waste, excessive 
water flow will get inside the tool and trip the GFCI.
4. Set the base plate on the workpiece and align to the cutting mark on the\
 base plate 
to cut line on stone.
5. Press the on/off switch to start the motor and allow the tool to attain \
full speed before 
starting to cut.
6. Advance the tool 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.
7. Slow the cutting speed for the last 1/2” to prevent the tile or stone from chipping.
 
 OPTION 2: USING THE RULER GUIDE
Install the ruler on the AWS-125 by inserting the arms into the  appropriate slots on the 
base plate and tightening the screws to secure the ruler in place. When using the edge 
of the stone as your guide, install the ruler so that it is below the ba\
se plate (Figure-17). 
Measure the distance from the edge to the intended cut and use this measurement 
to set the ruler at the proper distance. When using a straight edge as a guide, install 
the ruler so that it is above the base plate (Figure-18). Measure the \
distance from the 
straight edge to the intended cut and use it to set the ruler at the proper distance. \
When cutting, simply keep the ruler in contact with the straight edge while 
maintaining even 
cutting pres-
sure and your 
cuts will b e

straight. 
 OPTION 3: USING THE CARRIAGE ASSEMBLY AND GUIDE RAIL
Install the guide rail 2-3/4 inches / 70mm from the intended cut. Take care to ensure that 
the guide rail is properly clamped in place and double check your measur\
ements. Attach 
the carriage assembly to the base plate by aligning the base plate prope\
rly and attaching 
the pressing plates. Make sure that the pressing plates are securely fas\
tened. The AWS 
should be immobile with in the carriage assembly. Slide the carriage onto the guide rail and 
proceed to cut. Maintain even cutting pressure. When finished, the rail is in position to polish 
the straight edge with the Alpha® Edgecrafter.  Adjusting cutting depth:
Loosen the wing bolt on the depth indicator and move the base floor up and down to the 
desired cutting depth and tighten the wing nut to fix the base floor.  
Remember to tighten the wing bolt after you finish the adjustment of the cutting depth each 
time.

 CURVE CUTTING APPLICATION
When cutting the curved line, you can remove the ruler guide and cut fre\
e-hand. (Figure-8) 
Step 1. Score along the cutting line (1/3 width of stone).
Step 2. Step-cut along scored line (2/3 width of stone).
Step  3. Plunge cut all the way to make full contact between bottom plate and sto\
ne, then 
maintain even cutting pressure to follow curved cut line. 
     WARNING!
Support the sink cutout area; sinkhole cutout piece may drop to the floor at the end of cut-
ting 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.  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.

BLADE INSPECTION, INSTALLATION, AND REMOVAL
  DANGER!
Be sure to unplug the power cord from the outlet before attaching or rem\
oving the 
saw blade from the tool.  Accidental starting of the motor may cause bodily injury. 
  WARNING!
Be sure to securely tighten the flange assembly and all loose screws before testing the unit.  
Please allow the saw blade to do the work.  Applying excessive force may damage the saw 
blade and cause premature failure of the bearings and gears.  Such action may decrease 
the rotation speed of the motor which reduces the efficiency of the dust suction because 
its power is driven by the spindle
Only use saw blades with 20mm arbors and maximum speed rating equal to or higher than 
the name plate of RPM of tool.
1. To remove the flange bolt from the spindle hold Flange II in position with the 22 mm 
spanner wrench (133097) while turning the flange bold with the T-handle wrench 
(133098) in a clockwise rotation until it is removed.
2. With the flange bolt removed, remove Flange II off of Flange I.
3. Install your 20mm arbor saw blade onto Flange I with the arrow on the bl\
ade pointing 
in the same direction as the arrow on the cover (blade will turn in a clockwise rotation), 
the cutting wheel should fit tightly on the Flange I.
4. Reinstall Flange II and then the flange bolt, turning counter-clockwise to install, once 
flange bolt is hand tight use the 22mm spanner wrench to hold Flange II in place and 
finish tightening the flange bolt with the T-handle wrench.

AWS-125 MAINTENANCE
 DAILY
1. Before daily start-up inspect tool, power cord, GFCI, and Saw Blade, loo\
king for chips 
and cracks.
2. If damage has occurred, repair affected areas before use.
3. Connect the tool to the correct power source and test the Ground Fault C\
ircuit Interrupter 
(GFCI) before using the tool.  Push the red RESET button and confirm that the red run 
light is on.  Push the yellow TEST button and confirm that the red run light is off, push 
the red RESET button to use the tool.
4. After daily use of the tool, clean and blow off the exterior of tool and\
 around air intake 
vents to remove any standing water or stone dust on the field coil, carbon brushes, 
and bearings.  Failure to do this will shorten the life of your tool, and could void your 
warranty.
 PERIODIC
Preventive maintenance performed by unauthorized personnel may result in\
 misplacing of 
internal wires and/or components which voids the warranty and could cause serious hazards.  
We recommend that tool service and repairs not covered in the manual be performed by 
an Alpha® Repair Center.
Periodic maintenance is done to check the tool and to minimize down time\
.  These checks 
are done based on hours of operation and operating conditions.  Operatin\
g condition can 
vary depending on the work surface and job being performed.  If the tool is not used for a 
long period of time the carbon brushes should be checked and the commuta\
tor cleaned, 
before putting the tool back into operation.
 BEARINGS AND GEARS
To minimize your tool’s downtime and expensive repairs, it is recommended to send the tool 
back to an Alpha® Repair Center after about 300 to 400 hours of operation, or every secon\
d 
carbon brush change.  The bearings should be replaced and the gears should be checked.  
If your tool starts to sound different, this could be an indication of a\
 worn bearing.  Continuing 
to use to use the tool in this condition could result in overheating or \
motor failure.
