Additional Safety Warnings - Dremel 8260 Operating/Safety Instructions Manual

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
excessive pressure. Do not attempt to
make an excessive depth of cut.
Overstressing 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
kickback 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.
a. GFCI and personal protection devices
like electrician's rubber gloves and
footwear will further enhance your
personal safety.
b. Keep handles dry, clean and free from
oil and grease. Slippery hands cannot
safely control the power tool.
c. Develop a periodic maintenance
schedule for your tool. When cleaning
a tool be careful not to disassemble
any portion of the tool since internal

Additional Safety Warnings

g. 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.
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
objects 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
operation. Do not overstress the wires
by applying 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
bristles or wires will be discharged during
the run-in time.
c. Direct the discharge of the spinning wire
brush away from you. Small particles and
tiny wire fragments may be discharged at
high velocity during the use of these
brushes and may become imbedded in
your skin.
wires may be misplaced or pinched or
safety guard return springs may be
improperly mounted. Certain cleaning
agents such as gasoline, carbon
tetrachloride, ammonia, etc. may
damage plastic parts.
d. Ensure the switch is in the off position
before inserting battery pack. Inserting
the battery pack into power tools that
have the switch on invites accidents.
