ment devices can unexpectedly shift, causing loss of
control, loose rotating components will be violently
thrown.
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 materi-
als. Sparks could ignite these materials.
Do not use accessories that require liquid coolants.
Using water or other liquid coolants may result in elec-
trocution 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 modifica-
tion 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 acces-
sory. 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 mate-
rial 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 incor-
rect 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 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 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 direc-
tion 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 cut-
ting 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 abra-
sive 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 periph-
eral 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 shoul-
der 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
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
