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 the miter guide whenever pos-
sible.
Another problem is cutting difficult material. To prevent chip-
ping of the material at the end of the cut, use a plunge cut.
NOTE: A more shallow cutting wheel adjustment may help
minimize chipping, see the Depth stop adjustments sec-
tion.
Clean the saw table and miter guide frequently during use.
Debris from the cut material can interfere with tool function.
WARNING:
Use of controls or adjustments or performance of
procedures other than those specified herein may
result in hazardous radiation exposure.
