ADJUSTING THE 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 5 and Figure 6.
 
RULER GUIDE USAGE OPTION
According to the application, there are two options for using the ruler \
guide.
1.  Install the ruler on the Ecocutter by inserting the arms into the approp\
riate slots on the 
base plate and tightening the screws to secure the ruler in place as shown in Figure  7 
and Figure 8.

2.  When cutting, simply keep the ruler in contact with edge of stone or the\
 straight edge 
while maintaining even cutting pressure to ensure the cuts will be strai\
ght.
 OPTION A - GUIDE BELOW THE BASE PLATE
When using the edge of the stone as your guide, install the ruler guide down-
ward so that the ruler guide would be below the base plate and the inner\
 
side of the ruler guide would follow the edge of the stone.  Measure the 
distance from the edge to the indented cut and use this measurement to set 
the ruler at the proper distance. (See Figure 9)
 OPTION B - GUIDE ABOVE THE BASE PLATE
When using the straight edge as a guide, install the ruler guide upward \
so 
that the ruler guide would be above the base plate and the outer edge of\
 the 
ruler guide would follow the edge of the straight edge.  Measure the dis\
tance 
from the straight edge to the intended cut and use it to set the ruler a\
t the 
proper distance. (See Figure 10)

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
1.	 Remove	flange	bolt
 (left-hand thread) as 
shown in Figure 17.
2.	 Remove	 outer	flange	 as	
shown in Figure 18.

3.  Set the rotation direction of the blade so that it matches the Ecocutter\
 rotation arrow 
located on the guard as shown in Figure 19.
4.	 Slide	the	blade	between	the	inner	flange	and	guard	as	shown	in	Figure	20.

							ECOCUTTER MAINTENANCE
 DAILY
1. Before daily start-up inspect tool, power cord, circuit breaker assembly, and saw blade 
looking for chips and cracks.  Inspect the dust bag for holes or if it i\
s full and needs 
to be replaced.
2. If damage has occurred, repair affected areas before use.
3. Turn	the	unit	 on	to	ensure	 that	the	fan	is	running	 and	the	dust	 bag	is	inflating,	 a	new 	
bag	will	not	inflate	until	the	pores	in	the	material	start	to	fill	with	stone	dust.
4. After daily use of the tool, clean and blow off the exterior of tool and around air intake 
vents on rear of motor housing.
 PERIODIC
Preventive maintenance performed by unauthorized personnel may result in misplacing of 
internal wires and/or components which voids the warranty and could caus\
e 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 commutator 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 shou\
ld 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.

 CARBON BRUSH REPLACEMENT
1.  Locate the Carbon Brush Caps at the rear of the motor (one on each side\
) as shown 
in Figure 23.
2.  Unscrew cap completely until carbon brush assembly releases from brush h\
older as 
shown in Figure 24.
Carbon Brush Cap
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 di\
sassembling the 
tool.  Accidental starting of the motor may cause bodily injury.

							Proper Alignment
4.  Install new carbon brush with the proper alignment of the brush holder f\
ollowed by the 
cap as shown in Figure 26.

damaged.
