Dremel 8150 Instructions D’utilisation Et De Sécurité page 6

a. Maintain a firm grip on the power tool
and position your body and arm to allow
you to resist kickback forces. The opera-
tor can control kickback forces, if proper
precautions are taken.
b. Use special care when working corners,
sharp edges etc. Avoid bouncing and
snagging the accessory. Corners, sharp
edges or bouncing have a tendency to snag
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 di-
rection 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.
3. 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 example:
do not grind with the side of a cut-off
wheel. Abrasive cut-off wheels are intend-
ed for peripheral grinding, side forces ap-
plied 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. Overstressing
the wheel increases the loading and sus-
ceptibility to twisting or snagging of the
wheel in the cut and the possibility of kick-
back 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 attempt to
remove the cut-off wheel from the cut
while the wheel is in motion otherwise
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 pinch-
ing 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.
h. Use extra caution when making a "pocket
cut" into existing walls or other blind ar-
eas. The protruding wheel may cut gas or
water pipes, electrical wiring or objects
that can cause kickback.
4. 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
clothing and/or skin.
b. Allow brushes to run at operating speed
for at least one minute before using
them. During this time no one is to stand
in front or in line with the brush. Loose
