the line of the cut. Bent or warped workpieces
can twist or rock and may cause binding on the
spinning saw blade while cutting. Also, make sure
there are no nails or foreign objects in the work-
piece.
• Do not use the saw until the table is clear of all
tools, wood scraps, etc., except the work-
piece. Small debris or loose pieces of wood or
other objects that contact the revolving blade can
be thrown with high speed at the operator.
• Do not feed workpiece into the blade or cut
"freehand" in any way. Workpiece must be
stationary and clamped or braced by your
hand. Saw must be fed through the workpiece
smoothly and at a rate which will not overload the
saw's motor.
• Cut only one workpiece at a time. Multiple
workpieces cannot be adequately clamped or
braced and may bind on the blade or shift during
cutting.
• Be certain the miter saw is mounted or placed
on a level, firm work surface before using. A
level and firm work surface reduces the risk of the
miter saw becoming unstable.
• plan your work. provide adequate support
accessories such as tables, saw horses, table
extension, etc. for workpieces wider or longer
than the table top (see page 21). Workpieces
longer or wider than the miter saw table can tip if
not securely supported. If the cutoff piece or work-
piece tips it can lift the lower guard or be thrown
by the spinning blade.
• Do not use another person as a substitute for
a table extension or as additional support.
Unstable support for the workpiece can cause the
blade to bind or the workpiece to shift
during the cutting operation pulling you and the
helper into the spinning blade.
• The cutoff piece must not be jammed against
or pressured by any other means against the
spinning saw blade. If confined, i.e. using length
stops, it could get wedged against the blade and
thrown violently.
• Always use a clamp or a fixture designed to
properly support round material such as
