Operating/Safety Instructions
IMPORTANT: Read Before Operating Equipment
To avoid accidents or injury, keep work area clean, well lit, and well
Always wear eye, hand, and all other appropriate protective apparel
when operating saw.
Keep all other people, children, and small farm animals away while
operating saw.
Use only properly grounded, GFCI protected electrical outlet. GFCI
must be tested every 2 months.
Warning: Do NOT turn machine on or off with the GFCI safety switch.
Turn machine toggle switch off before resetting the GFCI.
Ensure that the electrical system in your work location meets all codes
and regulations prior to operating saw.
Do not modify the plug on the saw or use any adapters between the saw
and the electrical outlet.
Do not allow water to run directly on the motor or any other electrical
If power cord or any other part of the saw is damaged, discontinue use
immediately until damaged parts can be replaced.
Keep saw blade clear of clothing, jewelry, hair, cords, hoses, or any other
object while in operation.
Ensure that the saw is switched off (trigger released) before plugging or
unplugging it.
Ensure that blade is clamped firmly between flanges and spinning freely
prior to operating.
Do not stand directly in front of or behind the saw while in operation.
Keep hands on top of the saw and away from the blade while operating.
Never force the saw if it seems to be stuck or if it seems to be moving
with difficulty.
Use only blades of correct size and shape. Do not modify blades.
Do not force bolts; most have been assembled with a threadlocking
adhesive for safety.

Operating Instructions
Installing/Replacing Blade:
Note: This saw is designed for stone and masonry applications
exclusively. For optimal performance use only blades from Omega
Place the saw on the rail (with rail rubber side down) providing
clearance for installing the blade. Loosen Vertical Adjustment lock and
raise motor to full height.
Remove the left-hand threaded bolt
holding the flanges to the shaft. If bolt is
tight, use the included wrench to turn it.
(To lock the shaft, press and hold the shaft
lock pin behind the blade guard and rotate
the flange until the pin locks.)
Shaft lock pin located on
front of motor.
Remove the front flange (and old
blade, if applicable) and slide the new
blade against the rear flange top first. Ensure that the blade is flat against
the rear flange with rotation direction arrow facing clockwise. Arrow
and other blade labels might be facing the motor or facing out, depending
on blade manufacturer (see Spin Direction, pg 6).
Replace the front flange so the blade is sandwiched between the two
flanges. Replace the left-hand threaded bolt and tighten with included
wrench. (To lock the shaft, press and hold the shaft lock pin behind the
blade guard and rotate the flange until the pin locks.)

Typical Operation:
Note: For most cutting operations, it is recommended that you lay your
slab on top of a foam sheet at least 1” (3cm) thick. (1.5” (4cm) is
preferred for less crumbling).
1) Lay the rail on the slab along the line to be cut.
2) Allow the rails to overhang enough for the blade to clear the stone
where you will begin your cut. It may be necessary to clamp the rails to
the stone to prevent wandering. Clamp onto provided angle bolted to
one side of rail.
3) Put the saw on the left side of the rail. (Blade outside stone with the
handle pointed over the stone.)
4) Adjust the blade height to just enter the stone about ¼ inch (3mm)
5) Turn the water valve on and adjust desired flow.
6) Turn saw on before blade touches the stone. Do not stand directly in
front of or behind the blade while cutting.
7) Slowly begin your cut by pulling the saw into the stone. After
entering the cut, draw the saw along the stone at good speed to finish the
“strike” cut. You may need to apply pressure to the top of the saw to
keep it from “climbing” out of the cut
8) After clearing the stone on the right side of the slab, re-position the
motor to the lowest position the blade can be set. The deeper the blade
cuts through the stone, the easier and faster the blade will cut.
9) Slowly enter the cut by pushing the saw into stone. If you enter the
cut too fast, the saw will bog down too far and may trip the electrical
breaker, and can also cause the blade to wander.
10) Once you have initiated the cut you must not go to slow or the
diamonds on the blade will glaze over, and the cutting speed will drop
dramatically. The speed of cut should be just below the point of bogging
the motor.
Example: On a 2 cm thick slab of Absolute Black granite try to
maintain a cutting speed of about 4 fpm (1 meter per minute) or faster.

Blade seems to be cutting slowly or not cutting at all?
Suggestions: Make sure the blade is mounted to spin in the proper
direction (See Spin Direction, pg 6).
The material being cut may have “loaded” or “glazed” the diamond.
Use a dressing stone or “green stone” to free the diamond.
Blade binds or “freezes.”
Suggestions: The blade may be cutting at a slight angle. Check
alignment. Make sure that the saw is rolling freely on the rails and the
rails are not damaged or bent. Make sure that the motor is securely
fastened to the mounting plate.
Saw shuts off after a few minutes of use and/or fails to turn
on at all.
Suggestions: Check circuit breaker. If that is on and it still fails to
start, the motor may have overheated and may need to be replaced.
Also check the brushes in the motor. If these are worn out you can
either order them from us, directly from the motor manufacturer, or pick
them up from your local hardware store.

Spin Direction
Some of the supported motors have an arrow on the guard indicating
the spin direction of the blade. If the spin direction of the blade is not
indicated, then it may be safe to assume that it spins in a clockwise
