capacity rating of your power tool. Incorrectly sized accessories cannot be
adequately guarded or controlled.
f)
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.
g)
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.
h)
Wear personal protective equipment. Depending on application, use a face
shield, safety goggles or safety glasses. As appropriate, wear dust mask,
hearing protectors, gloves and workshop apron capable of stopping small
abrasive or work piece 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.
i)
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.
j)
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.
k)
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.
l)
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.
m) 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.
o)
Do not operate the power tool near flammable materials. Sparks could ignite
these materials.
p)
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.
a)
Maintain a firm grip on the power tool and position your body and arm to allow
you to resist kickback forces. Always use auxiliary handle, if provided, for
