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	mo-
tor 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	ap-
plicable 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-110/AWS-220 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.
3.  Place strips on base plate parallel with the 
blade and press into place.

 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 be-
tween the body and the base plate. (See 
Figure-6)
3.  Insert the plastic nozzle on the water feed assembly behind the height a\
djustment 
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 screw.

 WATER FLOW   
  DANGER!
 Always check that the GFCI unit is working correctly (reset, test, and \
reset) 
before using this tool in a wet condition.  Do not use the tool if the G\
FCI is not 
working properly
Connect the nylon hose onto the water valve, then 
connect the adapter on the nylon hose to the water 
faucet.
Simply	adjust	the	volume	 of	the	 water	 flow	by	turning 	
the handle on the water valve.
ADJUSTING CUTTING DEPTH
1. Loosen the wing screw on the depth indicator and move the base plate up or down 
to the desired cutting depth.  Re-tighten the wing screw to a hand tight condition as 
shown in Figure 11 and Figure 12.

  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
1. 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 wor\
k).
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-110 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 base plate (Figure-13). 
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-14). 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 pressure and 
your cuts will be 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 attach the 
pressing plates. Make sure that the pressing plates are securely fastene\
d. The AWS should 
be immobile within the carriage assembly. Slide the carriage onto the guide rail and proceed 
to cut. Maintain even cutting pressure.  Adjusting cutting depth should be:
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.

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. 
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	 bolt	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 blade pointing 
in the same direction as the arrow on the cover (blade will turn in a c\
lockwise 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-110 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 Circuit Inter-
rupter	(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.   
						

							19
REPLACING AND CHECKING THE CARBON BRUSHES
In order to keep your tool running correctly, you need to check your carbon brushes after 
every one hundred hours (100 hrs) of use.  Carbon brushes wear out ove\
r time based on 
tool’s usage.  If a carbon brush is worn out, it may cause the motor to malfu\
nction or fail 
to	run.		 The	carbon	 brushes	 should	be	replaced	 when	they	are	worn	 down	 to	a	quarter	 of	
an	inch	(1/4”)	in	size.
  DANGER!
Be sure to unplug the power cord from the outlet before assembling or disassembling the 
tool.  Accidental starting of the motor may cause bodily injury.
 CARBON BRUSH REPLACEMENT
1.  Locate the Carbon Brush Caps at the rear of the motor (one on each side\
) as shown 
in Figure 17.
2.  Unscrew cap completely until carbon brush assembly releases from brush h\
older as 
shown in Figure 18.
