The rated speed of the accessory must be at
least equal to the maximum speed marked on
the power tool. Accessories running faster
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.
Application tools with threaded insert must
exactly fit the thread size of the spindle. For
application tools mounted by flanges, the
arbor hole of the application tool must fit the
mounting hole diameter of the flange. Appli-
cation tools that are not precisely mounted to
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, backing pad for
cracks, tear or excess wear, wire brush for
loose or cracked wires. If power tool or acces-
sory 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 testtime.
Wear personal protective equipment. Depend-
ing on application, use face shield, safety
goggles or safety glasses. Where appropriate,
wear dust mask, hearing protectors, gloves
and workshop apron capable of stopping
small abrasive or workpiece fragments. The
safety glasses must be capable of protecting
against flying particles generated by the vari-
ous operations. Prolonged exposure to high
intensity noise may cause loss of hearing.
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 acces-
sory may fly away and cause injury beyond
immediate area of operation.
Hold the power tool by insulated gripping sur-
faces only, when performing an operation
where the cutting accessory may contact hid-
den 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.
Position the cord clear of the spinning acces-
sory. 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 acces-
sory.
Never lay the power tool down until the acces-
sory has come to a complete stop. The spin-
ning 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 spin-
ning accessory could snag your clothing, pull-
ing 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 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.

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 uncontrolledpower
tool to be forced in the direction opposite 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
wheel that is entering into the pinch point can
dig into the surface of the material causing the
wheel to climb out or kick out. 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.
