the rotating accessory and cause loss of
control or kickback.
c) Do not attach a toothed saw blade. Such
blades create frequent kickback and loss of
control.
d) always feed the bit into the material in
the same direction as the cutting edge
is exiting from the material (which is the
same direction as the chips are thrown).
Feeding the tool in the wrong direction
causes the cutting edge of the bit to climb
out of the work and pull the tool in the direc-
tion of this feed.
e) When using rotary files, cut-off wheels,
high-speed cutters or tungsten carbide
cutters, always have the work securely
clamped. These wheels will grab if they be-
come slightly canted in the groove, and can
kickback. When a cut-off wheel grabs, the
wheel itself usually breaks. When a rotary
file, high-speed cutter or tungsten carbide
cutter grabs, it may jump from the groove
and you could lose control of the tool.
safety warnings specific for grinding
and abrasive cutting-off operations:
a) use only wheel types that are recom-
mended for your power tool and only for
recommended applications. For exam-
ple: do not grind with the side of a cut-
off wheel. Abrasive cut-off wheels are in-
tended for peripheral grinding, side forces
applied to these wheels may cause them to
shatter.
b) For threaded abrasive cones and plugs
use only undamaged wheel mandrels
with an unrelieved shoulder flange that
are of correct size and length. Proper
mandrels will reduce the possibility of
breakage.
c) Do not "jam" a cut-off wheel or apply ex-
cessive pressure. Do not attempt to
make an excessive depth of cut. Over-
stressing the wheel increases the loading
and susceptibility to twisting or snagging of
the wheel in the cut and the possibility of
kickback or wheel breakage.
d) Do not position your hand in line with
and behind the rotating wheel. When the
wheel, at the point of operation, is moving
away from your hand, the possible kick-
back may propel the spinning wheel and the
power tool directly at you.
e) When wheel is pinched, snagged 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 complete stop. never at-
tempt to remove the cut-off wheel from
the cut while the wheel is in motion oth-
erwise kickback may occur. Investigate
and take corrective action to eliminate the
cause of wheel pinching or snagging.
f) Do not restart the cutting operation in
the workpiece. let the wheel reach full
speed and carefully re-enter the cut. The
wheel may bind, walk up or kickback if the
power tool is restarted in the workpiece.
g) support panels or any oversized work-
piece to minimize the risk of wheel
pinching and kickback. Large workpieces
tend to sag under their own weight. Sup-
ports must be placed under the workpiece
near the line of cut and near the edge of
the workpiece on both sides of the wheel.
h) 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 ob-
jects that can cause kickback.
safety warnings specific for wire brushing
operations:
a) be aware that wire bristles are thrown by
the brush even during ordinary opera-
tion. Do not overstress the wires by ap-
plying excessive load to the brush. The
wire bristles can easily penetrate light cloth-
ing and/or skin.
