GENERAL CUT OFFS
Maintain a firm grip and operate the switch with
a decisive action. Never force the tool. Use a
light and continuous pressure (Fig. 10).
After completing a cut and the
W RNING
switch has been released, be
aware of the necessary time it takes for the
wheel to come to a complete stop during coast
down. Do NOT set the tool down until the
accessory has come to a complete stop.
1. Make sure material being cut is secured in a
vise or fixture before attempting to cut
2. Keep your body positioned to either side of
the wheel, but not in line with the wheel. It is
important to support the tool properly and to
position your body such as to minimize body
exposure from possible wheel binding and
recoil.

CUTTING TILE

Make sure material being cut is secured in a
vise or fixture before attempting to cut.
Turn the tool on and wait for the wheel to reach
full speed. For cuts that extend to the edge of a
tile, cut all the way through edge(s) along your
cut line.

CUTTING METAL

It is possible to perform limited cutting on small
stock such as copper pipe, conduit, coated wire
shelving, HVAC, aluminum sheet, cutter, and
fascia.
Do not make repeated cuts,
W RNING
or cut longer then 2 feet in
sheet metal. Sparks may damage guard.
Recommended Maximum
Material Thicknes
s
Threaded Rod 5/16" (7.9 mm)
Sheet Metal 1/32" (20 Gauge) (.91 mm)
Conduit 1/2" (12.7 mm)
Masonry Score and then break
When cutting, work with moderate feed,
adapted to the material being cut. Do not exert
side pressure onto the cutting wheel, tilt or
oscillate the tool.

3. Grip the tool firmly while cutting and always
be ready and able to manage the cut.
4. Avoid jamming, twisting or pinching the wheel
with the workpiece of otherwise applying
excessive side pressure to the wheel.
Score the tile first along your cut line, making
multiple passes to progressively cut through
the tile.
This tool does not use wheels designed for
face-grinding. If your cut requires a smooth,
finished edge, use an appropriate tile finishing
tool to refine the tile edge.
When cutting profiles and square bar, it is best
to start at the smallest cross section. Always
follow precautions for kickback.
Do not apply side pressure to cutting wheel to
reduce wheel speed. The tool should always
be used so that sparks are directed away from
user.
After each use, remove the wheel and clean
the inside and outside of the guard with
compressed air. Preventive maintenance of
the guard will reduce the probability of an
accident.
When cutting cylindrical metal materials such
as conduit, copper tubing, threaded rod and
wire shelving up to ½" in diameter, use the
SM846 chop saw attachment. See page 17
for instructions.
