SAFETY RULES FOR ROTARY TOOL (CONTINUED)
dropped while 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 when-
ever practical. Never hold a small work-
piece 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 work-
pieces, 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 with
compressed air. Excessive accumulation of
powdered metal inside the motor housing
may cause electrical failures.
Do not allow familiarity gained from fre-
quent 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 med-
ical applications. Serious 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 cant-
ed 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 cut-
off wheel grabs, the wheel itself usually
breaks. When the steel saw, high speed cut-
ters or tungsten carbide cutter grab, it may
jump from the groove and you could lose
control of the tool.
Some dust created by
power drilling and other
construction activities, contains chemi-
cals known to cause cancer, birth defects
or other reproductive harm. Some exam-
ples 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.
