LOck-OFF BUTTON
See Figure 6, page 14.
The lock-off button reduces the possibility of accidental
starting. The lock-off button is located on the handle above
the switch trigger. The lock-off button must be depressed
before you pull the switch trigger. The lock resets each time
the trigger is released.
NOTE: You can depress the lock-off button from either the
left or right side.
AdJUSTiNG whEEL dEPTh
See Figure 7, page 14.
Always keep correct wheel depth setting. The correct wheel
depth setting for all cuts should not exceed 1/4 in. below the
material being cut. More wheel depth will increase the chance
of kickback and cause the cut to be rough. For more depth
of cut accuracy, a scale is located on the rear bracket.

Loosen the depth adjustment knob.
 Determine the desired depth of cut.
 Locate the depth of cut scale on the rear bracket.
 Hold the base flat against the workpiece and raise or
lower the saw until the indicator mark on bracket aligns
with the notch on the wheel guard.
 Tighten the depth adjustment knob securely.
OPERATiNG ThE SAw
See Figures 8 - 9, page 14.
It is important to understand the correct method for operat-
ing the saw. Refer to the figures in this section to learn the
correct and incorrect ways for handling the saw.
wARNiNG:
To make sawing easier and safer, always maintain proper
control of the saw. Loss of control could cause an ac-
cident resulting in possible serious injury.
wARNiNG:
When lifting the saw from the workpiece, the wheel is
exposed on the underside of the saw.
To make the best possible cut:

Hold the saw firmly with both hands.
 Avoid placing your hand on the workpiece while making
a cut.
 Support the workpiece so that the cut (kerf) is always to
your side.
 Support the workpiece near the cut.
 Clamp the workpiece securely so that the workpiece will
not move during the cut.
OPERATiON
 Always place the saw on the workpiece that is supported,
not the “cut off” piece.
 Place the workpiece with the “good” side down.
 Draw a guideline along the desired line of cut before
beginning your cut.
MAkiNG cUTS
Always draw the line to be cut on the tile using a marker or
grease pencil. If the tile is shiny and hard-to-mark, place
masking tape on the tile and mark the tape.
A common problem when cutting tile is straying from the
marked line. Once you’ve strayed from the mark, you can not
force the wheel back to the line by twisting the tile. Instead,
back up and recut the tile slicing off a small amount of tile
until the wheel is back on track.
To avoid this problem, use a straight edge guide whenever
possible for making cross cuts and miter cuts.
If wet cutting is desired, it should be performed outside.
TO MAkE A cROSS cUT
See Figure 10, page 14.
Cross cuts are straight 90º cuts. The material is fed into the
cut at a 90º angle to the wheel, and the wheel is vertical.

Using a marker or grease pencil, mark the area to be cut
on material.
 Secure the workpiece.
 If wet cutting is desired, fill the water bottle and attach
to saw as instructed. Then turn the water control valve
to start water flow.
 Depress the switch trigger to start the saw.
 Let the cutting wheel build up to full speed and wait for
the wheel to get wet before moving the wheel into the
material.
 When the cut is made, release the switch trigger. Wait
for the cutting wheel to come to a complete stop before
removing the saw from the material.
 Turn water control valve off.
TO MAkE A diAGONAL cUT
See Figure 11, page 15.
Diagonal cuts are also referred to as “long point to long
point cuts”.

Using a marker or grease pencil, mark the area to be cut
on material.
 Secure the workpiece.
 If wet cutting is desired, turn the water control valve to
start water flow.
 Depress the switch trigger to start the saw.
 Let the cutting wheel build up to full speed and wait for
the wheel to get wet before moving the wheel into the
material.
