Wire and bristle brushes must never be operated
at speeds greater than 15,000/min. Direct the dis-
charge of the spinning wire brush away from you.
Small particles and tiny wire fragments may be dis-
charged at high velocity during the "cleaning" action
with these brushes and may become imbedded in
your skin. Bristles or wires will be discharged from
the brush at high speeds.
"Wear protective gloves and face shield with wire
or bristle brushes. Apply wire or bristle brushes
lightly to the work as only the tips of the wire/bris-
tles do the work. "Heavy" pressure on bristles will
cause the wire or bristle to become overstressed,
resulting in a wiping action and will cause the bris-
tles/wire to be discharged."
Carefully handle both the tool and individual grind-
ing wheels to avoid chipping or cracking. Install a
new wheel if tool is 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 dur-
ing use. Dull bits require more force to push the tool,
possibly causing the bit to break.
Use clamps to support workpiece whenever practi-
cal. 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 cut-
ting 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 mater-
ial causing loss of control of the cutter.
Avoid bouncing and snagging the wheel, especial-
ly 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 unexpect-
edly 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 fail-
ures.
Do not allow familiarity gained from frequent use
of your rotary tool to become commonplace.
Always remember that a careless fraction of a sec-
ond is sufficient to inflict severe injury.
