Safety Rules for Rotary Tools - (cont.)
4
any other accessory must properly fit the
spindle or collet of the power tool.
Accessories that do not match the mounting
hardware of the power tool will run out of
balance, vibrate excessively and may cause
loss of control.
Mandrel mounted wheels, sanding drums,
cutters or other accessories must be fully
inserted into the collet or chuck. If the
mandrel is insufficiently held and/or the
overhang of the wheel is too long, the mounted
wheel may become loose and be ejected at
high velocity.
Do not use a damaged accessory. Before
each use inspect the accessory such as
abrasive wheels for chips and cracks,
sanding drum for cracks, tear or excess
wear, wire brush for loose or cracked wires.
If power tool or accessory is dropped,
inspect for damage or install an undamaged
accessory. After inspecting and installing
an accessory, position yourself and
bystanders away from the plane of the
rotating accessory and run the power tool
at maximum no-load speed for one minute.
Damaged accessories will normally break apart
during this test time.
Wear personal protective equipment.
Depending on application, use face shield,
safety goggles or safety glasses. As
appropriate, wear dust mask, hearing
protectors, gloves and workshop apron
capable of stopping small abrasive or
workpiece fragments. The eye protection
must be capable of stopping flying debris
generated by various operations. The dust
mask or respirator must be capable of filtrating
particles generated by your operation.
Prolonged exposure to high intensity noise may
cause hearing loss.
Keep bystanders a safe distance away from
work area. Anyone entering the work area
must wear personal protective equipment.
Fragments of workpiece or of a broken
accessory may fly away and cause injury
beyond immediate area of operation.
Hold the power tool by insulated gripping
surfaces only, when performing an
operation where the cutting accessory may
contact hidden wiring or its own cord.
Cutting accessory contacting a “live” wire may
make exposed metal parts of the power tool
“live” and could give the operator an electric
shock.
Always hold the tool firmly in your hand(s)
during the start-up. The reaction torque of the
motor, as it accelerates to full speed, can cause
the tool to twist.
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. Clamping a small workpiece
allows you to use your hand(s) to control the
tool. Round material such as dowel rods, pipes
or tubing have a tendency to roll while being
cut, and may cause the bit to bind or jump
toward you.
Position the cord clear of the spinning
accessory. If you lose control, the cord may be
cut or snagged and your hand or arm may be
pulled into the spinning accessory.
Never lay the power tool down until the
accessory has come to a complete stop.
The spinning accessory may grab the surface
and pull the power tool out of your control.
After changing the bits or making any
adjustments, make sure the collet nut,
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.
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.
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.
Do not operate the power tool near
flammable materials. Sparks could ignite
these materials.
Do not use accessories that require liquid
coolants. Using water or other liquid coolants
may result in electrocution or shock.
Use only in well-ventilated area. Working in a
safe environment reduces risk of injury.
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.
Do not touch the bit or collet after use. After
use the bit and collet are too hot to be touched
by bare hands.
Do not alter or misuse tool. Any alteration or
