Additional Safety Instructions For Grinding And Cutting-Off Opera- Tions; Additional Safety Warnings Spe- Cific For Abrasive Cutting-Off Op- Erations - Panasonic EY4640 Manual De Instrucciones

4) Use special care when working
corners, sharp edges etc. Avoid
bouncing and snagging the ac-
cessory. Corners, sharp edges or
bouncing have a tendency to snag
the rotating accessory and cause
loss of control or kickback.
5) Do not attach a saw chain wood-
carving blade or toothed saw
blade. Such blades create frequent
kickback and loss of control.
Additional safety instructions for
grinding and cutting-off opera-
tions
Safety warnings specific for Grinding
and Abrasive Cutting-off operations:
1) Use only wheel types that are
recommended for your power
tool and the specific guard de-
signed for the selected wheel.
Wheels for which the power tool
was not designed cannot be ade-
quately guarded and are unsafe.
2) The guard must be securely at-
tached to the power tool and po-
sitioned for maximum safety, so
the least amount of wheel is ex-
posed towards the operator. The
guard helps to protect operator
from broken wheel fragments and
accidental contact with wheel.
3) Wheels must be used only for rec-
ommended applications. For exam-
ple: do not grind with the side of
cut-off wheel. Abrasive cut-off wheels
are intended for peripheral grinding,
side forces applied to these wheels
may cause them to shatter.
4) Always use undamaged wheel
flanges that are of correct size and
shape for your selected wheel.
Proper wheel flanges support the
wheel thus reducing the possibility of
wheel breakage. Flanges for cut-off
wheels may be different from grind-
ing wheel flanges.
5) Do not use worn down wheels
from larger power tools. Wheel
intended for larger power tool is not
suitable for the higher speed of a
smaller tool and may burst.
Additional Safety Warnings Spe-
cific for Abrasive Cutting-Off Op-
erations:
1) Do not "jam" the cut-off wheel or
apply excessive pressure. Do
not attempt to make an exces-
sive depth of cut. Overstressing
the wheel increases the loading
and susceptibility to twisting or
binding of the wheel in the cut and
the possibility of kickback or wheel
breakage.
2) Do not position your body in line
with and behind the rotating
wheel. When the wheel, at the point
of operation, is moving away from
your body, the possible kickback
may propel the spinning wheel and
the power tool directly at you.
3) When wheel is binding or when
interrupting a cut for any reason,
switch off the power tool and
hold the power tool motionless
until the wheel comes to a com-
plete stop. Never attempt to re-
move the cut-off wheel from the
cut while the wheel is in motion
otherwise kickback may occur.
Investigate and take corrective ac-
tion to eliminate the cause of wheel
binding.
4) Do not restart the cutting opera-
tion in the workpiece. Let the
wheel reach full speed and care-
fully reenter the cut. The wheel
may bind, walk up or kickback if the
power tool is restarted in the work-
piece.
5) Support panels or any oversized
workpiece to minimize the risk of
wheel pinching and kickback.
Large workpieces tend to sag under
their own weight. Supports must be
placed under the workpiece near the
line of cut and near the edge of the
workpiece on both sides of the
wheel.
