MASONRY
This tool
is not recommended
for continuous
and general
usage with metal or masonry

saw for cutting
these materials,
use the appropriate

wheel
and washers
that
comply
with
Occupational
Safety
Health
Administration
standards.
Oo not use any cut-off
wheel beyond
its safe speed.

across the grain, the fibers of the wood have a

OF
BLADES
A dull or damaged
blade slows the speed of cutting
and
places a heavy
load on your
saw motor,
and can cause
Kickback.
Keep extra blades on hand so that you always have
shara, efficient
blades ready to replace a dull or damaged one.
Always
use blades with correct size holes. Never use defective
or incorrect
blade washers or bolts, Remove all nails before
cutting;
hitting
a nail while cutting
seriously
damages the
blade. If this happens stop cutting, unplug the saw and replace
the blade before continuing.
Blades become dull even from cutting
regular lumber.
If you
find yourself
forcing
the saw forward
to cut, instead of just
guiding it through
the cut, chances are the blade is dull and
should be replaced.
Wher_ cleaning
gum and wood pitch from blade, unplug the
saw and remove the blade. Remember,
blades are designed to
cut,
so handle
carefully.
Wipe the blade with
kerosene
or
similar
solvent
to remove
the gum and pitch. Unless you are
experienced
in sharpening
blades, we recommend
you not try.
