Safety Rules for Cordless Rotary Tools - (cont.)
Do not reach in the area of the spinning bit.
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.
Wire and bristle brushes must never be
operated at speeds
15,000/min. Direct the discharge of the
spinning wire brush away from you.
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.
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.
Never use dull or damaged bits. Sharp bits
must be handled with care.
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.
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.
Never start the tool when the bit is engaged
in the material.
Avoid bouncing and snagging the wheel,
greater than
especially when working corners, sharp
edges etc.
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).
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.
Do not leave a running tool unattended,
turn power off.
Do not grind or sand near flammable
materials.
Do not touch the bit or collet after use.
Regularly clean the tool's air vents by
compressed air.
Do not allow familiarity gained from
frequent use of your rotary tool to become
commonplace.
