Safety Rules for Rotary Tools
chuck or any other adjustment devices
are securely tightened. Loose adjustment
devices can unexpectedly shift, causing
loss of control, loose rotating
components will be violently thrown.
p. Do not run the power tool while carrying
it at your side. Accidental contact with
the spinning accessory could snag your
clothing, pulling the accessory into your
body.
q. Regularly clean the power tool’s air
vents. The motor’s fan will draw the dust
inside the housing and excessive
accumulation of powdered metal may
cause electrical hazards.
r. Do not operate the power tool near
flammable materials. Sparks could ignite
these materials.
s. Do not use accessories that require
liquid coolants. Using water or other
liquid coolants may result in electrocution
or shock.
t. Use only in well-ventilated area. Working
in a safe environment reduces risk of
injury.
u. Allow for sufficient space, at least 6”,
between your hand and the spinning bit.
Do not reach in the area of the spinning
bit. The proximity of the spinning bit to
your hand may not always be obvious.
v. Do not touch the bit or collet after use.
After use the bit and collet are too hot to
be touched by bare hands.
w. Do not alter or misuse tool. Any
alteration or modification is a misuse and
may result in serious personal injury.
x. This product is not intended for use as a
dental drill, in human or veterinary
medical applications. Serious injury may
result.
Kickback and Related
Warnings
Kickback is a sudden reaction to a pinched
or snagged rotating wheel, backing pad,
brush or any other accessory. Pinching or
snagging causes rapid stalling of the
rotating accessory which in turn causes the
uncontrolled power tool to be forced in the
direction opposite of the accessory’s
rotation.
For example, if an abrasive wheel is
snagged or pinched by the workpiece, the
edge of the wheel that is entering into the
pinch point can dig into the surface of the
material causing the wheel to climb out or
kickout. The wheel may either jump toward
or away from the operator, depending on
direction of the wheel’s movement at the
point of pinching. Abrasive wheels may also
break under these conditions.
Kickback is the result of power tool misuse
and/or incorrect operating procedures or
conditions and can be avoided by taking
proper precautions as given below.
a. Maintain a firm grip on the power tool
and position your body and arm to allow
you to resist kickback forces. The
operator can control kickback forces, if
proper precautions are taken.
b. Use special care when working corners,
sharp edges etc. Avoid bouncing and
snagging the accessory. Corners, sharp
edges or bouncing have a tendency to
snag the rotating accessory and cause
loss of control or kickback.
c. Do not attach a toothed saw blade. Such
blades create frequent kickback and loss
of control.
d. 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.
e. When using rotary files, cut-off wheels,
high-speed cutters or tungsten carbide
cutters, always have the work securely
clamped. These wheels will grab if they
become slightly canted in the groove, and
can kickback. When a cut-off wheel grabs,
the wheel itself usually breaks. When a
rotary file, high-speed cutter or tungsten
carbide cutter grabs, it may jump from
the groove and you could lose control of
the tool.
Safety warnings specific for
grinding and abrasive
cutting-off operations:
a. Use only wheel types that are
recommended for your power tool and
only for recommended applications. For
example: do not grind with the side of a
cut-off wheel. Abrasive cut-off wheels are
intended for peripheral grinding, side
forces applied to these wheels may cause
them to shatter.
