Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
Do not use accessories that require liquid
coolants. Using water or other liquid coolants
may result in electrocution or shock.
Further safety warnings for all appli-
cations
Kickback and related warnings
Kickback is the sudden reaction to a pinched
or snagged rotating application tool, such as a
grinding wheel, sanding pad, wire brush, etc.
Pinching or snagging causes the rotating appli-
cation tool to rapidly stop. This causes an
uncontrolled power tool to be forced in the
direction opposite of the application tool's
rotation direction.
For example, if a grinding wheel is snagged or
pinched in the workpiece, the edge of the
grinding wheel that is entering into the work-
piece can be caught, causing the grinding
wheel to break out or cause kickback. The
sanding disc may either jump toward or away
from the operator, depending on the direc-
tion of the wheel at the point of blocking.
Grinding wheels can also break under these
conditions.
Kickback is the result of power tool misuse or
incorrect operating procedures. It can be
avoided by taking proper precautions as
described below.
Maintain a firm grip on the power tool and
position your body and arm to allow you to
resist kickback forces. The operator can con-
trol kickback forces, if proper precautions are
taken.
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.
Do not attach a toothed saw blade. Such
blades create frequent kickback and loss of
control.
Always feed the bit into the material in the
same direction as the cutting edge is exiting
from the material (which is the same direc-
tion 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 direction of this feed.
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 become 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.
Additional safety instructions for
grinding and cutting-off operations
Safety warnings specific for grinding
and abrasive cutting-off operations:
Use only wheel types that are recommended
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 intended for peripheral grinding,
side forces applied to these wheels may cause
them to shatter.
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.
Do not "jam" a cut-off wheel or apply exces-
sive 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.
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.
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 com-
plete stop. Never attempt to remove the cut-
off wheel from the cut while the wheel is in
motion otherwise kickback may occur. Inves-
tigate and take corrective action to eliminate
the cause of wheel pinching or snagging.
