Threaded mounting of accessories must
match the grinder spindle thread. For
accessories mounted by flanges, the
arbour hole of the accessory must fit the
locating diameter of the flange.
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.
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 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.

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.
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.
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 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. 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.
