Do not run the power tool while carrying it
at your side. Accidental contact with the
spinning accessory could snag your
clothing, pulling the accessory into your
body.
Regularly clean the power tool's air vents.
The motor's fan will draw the dust inside
the housing and excessive accumulation of
powdered metal may cause electrical
hazards.
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.
Use only in well-ventilated area. Working in
a safe environment reduces risk of injury.
Allow for sufficient space, at least 6",
between your hand and the spinning bit.
Do not reach in the area of the spinning
bit. The proximity of the spinning bit to your
hand may not always be obvious.
Do not touch the bit or collet after use.
After use the bit and collet are too hot to be
touched by bare hands.
Do not alter or misuse tool. Any alteration
or modification is a misuse and may result
in serious personal injury.
This product is not intended for use as a
dental drill, in human or veterinary medical
applications. Serious injury may result.
▶ Kickback and Related
Warnings
Kickback is a sudden reaction to a pinched
or snagged rotating wheel, backing pad,
brush or any other accessory. Pinching or
snagging causes rapid stalling of the
rotating accessory which in turn causes the
uncontrolled power tool to be forced in the
direction opposite of the accessory's
rotation.
For example, if an abrasive wheel is
snagged or pinched by the workpiece, the
edge of the wheel that is entering into the
pinch point can dig into the surface of the
material causing the wheel to climb out or
kickout. The wheel may either jump toward
or away from the operator, depending on
direction of the wheel's movement at the
point of pinching. Abrasive wheels may also
break under these conditions.
Kickback is the result of power tool misuse
and/or incorrect operating procedures or
Safety Rules for Rotary Tools
conditions and can be avoided by taking
proper precautions as given 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
control kickback
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 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
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.
▶ Safety warnings specific for
grinding and abrasive cutting-
off operations:
Use only wheel
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
excessive pressure. Do not attempt to
make an excessive depth of cut.
Overstressing the wheel increases the
5
forces, if proper
types that are
