will ensure that the safety of the power tool is maintained.

ADDITIONAL SPECIFIC SAFETY RULES

Safety Instructions for All Operations

a ) This power tool is intended to function as a grinder.
Read all safety warnings, instructions, illustrations
and specifications provided with this power tool.
Failure to follow all instructions listed below may result in
electric shock, fire and/or serious injury.
b ) Operations such as sanding, wire brushing, polishing
and cutting-off are not recommended to be
performed with this power tool. Operations for which
the power tool was not designed may create a hazard and
cause personal injury.
c ) Do not use accessories which are not specifically
designed and recommended by the tool manufacturer.
Just because the accessory can be attached to your power
tool, it does not assure safe operation.
d ) 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.
e ) The outside diameter and the thickness of your
accessory must be within the capacity rating of
your power tool. Incorrectly sized accessories can not 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 wheel 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 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.
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 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 electrical 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.
n ) 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.

OPERATIONS

Causes and Operator Prevention of Kickback

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 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
maximum control over kickback or torque reaction
during start up. The operator can control torque reaction
or kickback forces, if proper precautions are taken.
