Do not use accessories which are not spe-
cifically designed and recommended by the
tool manufacturer. Just because the acces-
sory can be attached to your power tool, it
does not assure safe operation.
The rated speed of the accessory must be at
least equal to the maximum speed marked
on the power tool. Accessories running fast-
er than their rated speed can break and fly
apart.
The outside diameter and the thickness of
your accessory must be within the capacity
rating of your power tool. Incorrectly sized
accessories cannot be adequately guarded
or controlled.
The arbor size of wheels, flanges, backing
pads or any other accessory must properly
fit the spindle of the power tool. Accesso-
ries with arbor holes that do not match the
mounting hardware of the power tool will run
out of balance, vibrate excessively and may
cause loss of control.
Do not use a damaged accessory. Before
each use inspect the accessory such as
abrasive wheels for chips and cracks, back-
ing pad 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. De-
pending on application, use face shield,
safety goggles or safety glasses. As appro-
priate, wear dust mask, hearing protectors,
gloves and workshop apron capable of stop-
ping small abrasive or workpiece frag-
ments. The eye protection must be capable
of stopping flying debris generated by vari-
ous operations. The dust mask or respirator
must be capable of filtrating particles gener-
ated 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 ac-
cessory may fly away and cause injury be-
yond immediate area of operation.
Hold power tool by insulated gripping sur-
faces only, when performing an operation
where the cutting accessory may contact
hidden wiring. Cutting accessory contacting
a "live" wire may make exposed metal parts
of the power tool "live" and shock the opera-
tor.
Position the cord clear of the spinning ac-
cessory. If you lose control of the power tool,
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 ac-
cessory has come to a complete stop. The
spinning accessory may grab the surface and
pull the power tool out of your control.
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 pow-
dered metal may cause electrical hazards.
Do not operate the power tool near flamma-
ble materials. Sparks could ignite these ma-
terials.
Do not use accessories that require liquid
coolants. Using water or other liquid cool-
ants may result in electrocution or shock.
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 accesso-
ry which in turn causes the uncontrolled
power tool to be forced in the direction op-
posite of the accessory's rotation at the
point of the binding.
For example, if an abrasive wheel is snagged
or pinched by the workpiece, the edge of the
