Safety Rules for Rotary Tools - (cont.)
grinding. Do not use a wheel that may be damaged.
Fragments from a wheel that bursts during operation
will fly away at great velocity possibly striking you or
bystanders.
Never use dull or damaged bits. Sharp bits must be
handled with care. Damaged bits can snap during
use. Dull bits require more force to push the tool,
possibly causing the bit to break.
Use clamps to support workpiece whenever
practical. Never hold a small workpiece in one hand
and the tool in the other hand while in use. Allow
for sufficient space, at least 6", between your hand
and the spinning bit. Round material such as dowel
rods, pipes or tubing have a tendency to roll while
being cut, and may cause the bit to "bite" or jump
toward you. Clamping a small workpiece allows you
to use both hands to control the tool.
Inspect your workpiece before cutting. When cutting
irregularly shaped workpieces, plan your work so it
will not slip and pinch the bit and be torn from your
hand. For example, if carving wood, make sure there
are no nails or foreign objects in the workpiece. Nails
or foreign objects can cause the bit to jump.
Never start the tool when the bit is engaged in the
material. The bit cutting edge may grab the material
causing loss of control of the cutter.
Avoid bouncing and snagging the wheel, especially
when working corners, sharp edges etc. This can
cause loss of control and kick-back.
The direction of feed with the bit into the material
when carving, routing or cutting is very important.
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.
If the workpiece or bit becomes jammed or bogged
down, turn the tool "OFF" by the switch. Wait for
all moving parts to stop and unplug the tool, then
work to free the jammed material. If the switch to
the tool is left "ON" the tool could restart
unexpectedly causing serious personal injury.
Do not leave a running tool unattended, turn power
off. Only when tool comes to a complete stop it is
safe to put it down.
Do not grind or sand near flammable materials.
Sparks from the wheel could ignite these materials.
Do not touch the bit or collet after use. After use the
bit and collet are too hot to be touched by bare hands.
Regularly clean the tool's air vents by compressed
air. Excessive accumulation of powdered metal inside
the motor housing may cause electrical failures.
Do not allow familiarity gained from frequent use of
your rotary tool to become commonplace. Always
remember that a careless fraction of a second is
sufficient to inflict severe injury.
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 personal injury may result.
When using the steel saws, cutoff wheels, high
speed cutters or tungsten carbide cutters, always
have the work securely clamped. Never attempt to
hold the work with one hand while using any of
these accessories. The reason is that these wheels
will grab if they become slightly canted in the groove,
and can kickback causing loss of control resulting in
serious injury. Your second hand should be used to
steady and guide the hand holding the tool. When a
cutoff wheel grabs, the wheel itself usually breaks.
When the steel saw, high speed cutters or tungsten
carbide cutter grab, it may jump from the groove and
you could lose control of the tool.

WARNING
drilling, and other construction activities contains
chemicals known to cause cancer, birth defects or
other reproductive harm. Some examples of these
chemicals are:
• Lead from lead-based paints,
• Crystalline silica from bricks and cement and other
masonry products, and
• Arsenic and chromium from chemically treated
lumber.
Your risk from these exposures varies, depending on
how often you do this type of work. To reduce your
exposure to these chemicals: work in a well ventilated
area, and work with approved safety equipment, such
as those dust masks that are specially designed to
filter out microscopic particles.
