WARNING!
Never place hands near the
cutting area. Proper positioning of your body
and hands when operating the mitre saw will
make cutting easier and safer. keep children
away. Keep all visitors at a safe distance from
the mitre saw. Make sure bystanders are clear
of the saw and workpiece. Don’t force the
saw. It will do the job better and safer at its
designed rate. Forcing the saw may cause
overheating. It’s important to avoid overheating
the blade by keeping it too low when cutting
hardwood. This can create a thermal crack
in the carbide, causing tip fragments to fly
backward to possibly injure the operator.
In general, a blade with more teeth
makes a smoother cut but runs
hotter. To avoid overheating, three
to five teeth should be engaged during a rip
cut. For crosscuts and sheet goods, five to
seven teeth should do the work.
To maintain the correct engaged-tooth ratio,
a blade with fewer teeth for cutting thick stock
would be ideal. Another solution is to adjust
the blade’s height (with the blade guard in
place). Raising the blade higher reduces the
number of teeth in the cut. It also increases
the hook angle, which makes the blade more
aggressive, so the cut’s quality decreases.
