WARNING
personal injury.
Do not use the saw until the table is clear of
all tools, wood scraps, etc., except the work-
piece. Small debris, 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 dur-
ing 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 29).
Workpieces longer or wider than the miter saw
table can tip if not securely supported. If the
cutoff piece or workpiece 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 sup-
port. 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
or pressured
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
dowel rods or tubing. Rods have a tendency
to roll while being cut, causing the blade to "bite"
and pull the work with your hand into the blade.
When cutting irregularly shaped work-
pieces, plan your work so it will not slip and
pinch the blade and be torn from your hand.
A piece of molding, for example, must lie flat or
be held by a fixture or jig that will not let it twist,
rock or slip while being cut.
"READ ALL INSTRUCTIONS" — Failure to follow the SAFETY RULES identified by
BULLET ( ) symbol listed BELOW, and other safety precautions, may result in serious
by any other
"SAVE THESE INSTRUCTIONS"
Safety
let the blade reach full speed before con-
tacting the workpiece. This will help avoid
thrown workpieces.
If the workpiece or blade becomes jammed
or bogged down, turn miter saw "Off" by
releasing switch. Wait for all moving parts
to stop and unplug the miter saw, then work
to free the jammed material. Continued saw-
ing with jammed workpiece could cause loss of
control or damage to miter saw.
Braking action of the saw causes the saw
head to jerk downward. Be ready for this
reaction when making an incomplete cut or
when releasing the switch before the head is
completely in the DOWN position.
After finishing the cut, release the switch,
hold the saw arm down and wait for blade to
stop before removing work or cutoff piece.
If blade does not stop within five (5) sec-
onds, unplug the saw and follow the instruc-
tions in the Troubleshooting section.
REACHING WITH YOUR HAND UNDER A
COASTING BLADE IS DANGEROUS!
There are additional safety instructions
for particular operations of the saw in the
Saw Operations section. Read the rest of the
manual for safe operation.
The GCM12SD miter saw has an extremely
smooth action and requires the operator to
firmly grip the handle before turning "ON" the
saw. for slide-action cutting, first grip the
switch handle in the Up position and pull out
back to the fully extended position. The blade
must clear the workpiece. Make certain the
clamp does not interfere with the guard and
head assembly. Second, turn saw "ON" and
means
lower the saw to the table. Then pUSH saw
through the workpiece. Release the switch and
wait for the blade to completely stop before
raising the head assembly and removing the
workpiece. Never "pullcut," since blade may climb
the workpiece, causing KICKBACK.
for chop-action cutting, move the head
assembly to the rear as far as it will go and
engage the mechanism lock. Then turn the saw
"ON" and lower the head assembly to make
the cut. Release the switch and wait for the
blade to completely stop before raising the
head assembly and removing the workpiece.
Failure to lock the mechanism can cause the blade
to suddenly climb up on the top of the
workpiece and force itself toward you.
