the tool is left “ON” the tool could restart unexpected-
ly 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 suf-
ficient to inflict severe injury.
Do not alter or misuse tool. Any alteration or modifi-
cation 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.
Some dust created by power
sanding, sawing, grinding,
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 fil-
ter out microscopic particles.
