Safety Rules for Cordless Rotary Tools - (cont.)
adjustment devices can unexpectedly shift,
causing loss of control, loose rotating
components will be violently thrown.
Do not reach in the area of the spinning bit.
The proximity of the spinning bit to your hand
may not always be obvious.
Allow brushes to run at operating speed for
at least one minute before using wheel.
During this time no one is to stand in front
or in line with the brush. Loose bristles or
wires will be discharged during the run-in time.
Wire and bristle brushes must never be
operated at speeds
15,000/min. Direct the discharge of the
spinning wire brush away from you. Small
particles and tiny wire fragments may be
discharged 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/bristles 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
bristles/wire to be discharged.
Carefully handle both the tool and
individual grinding 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 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
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,
greater than
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.
