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.
6) Use extra caution when making a
“pocket cut” into existing walls or
other blind areas. The protruding
wheel may cut gas or water pipes,
electrical wiring or objects that can
cause kickback.
