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 haz-
ards.
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 envi-
ronment 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 spin-
ning 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 conditions and can be avoided by
taking proper precautions as given below.
Maintain a firm grip on the power tool and position your
6
body and arm to allow you to resist kickback forces. The
operator can control 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 rotat-
ing accessory and cause loss of control or kickback.
Do not attach a toothed saw blade. Such blades create fre-
quent 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 cut-
ters 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 con-
trol of the tool.
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 grind-
ing, side forces applied to these wheels may cause them to
shatter.
For threaded abrasive cones and plugs use only undam-
aged 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 pres-
sure. Do not attempt to make an excessive depth of cut.
Overstressing the wheel increases the loading and suscep-
tibility 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
