• 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.
• 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.
• 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
and run the power tool at maximum no-load speed for one
minute. Damaged accessories will normally break apart during
thistest 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 filtering 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 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 shock the operator.
• 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.

nOTE: The above warning does not apply for power tools
specifically designed for use with a liquid system.
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.
• 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 reactions or kickback forces, if proper precautions
are taken.
• Never place your hand near the rotating accessory.
Accessory may kickback over your hand.
• Do not position your body in the area where power
tool will move if kickback occurs. Kickback will propel the
tool in direction opposite to the wheel's movement at the point
of snagging.
• Use special care when working corners, sharp edges etc.
Avoid bouncing and snagging the accessory. Corners, sharp
edges or bouncing have a tendency to snag the rotating accessory
and cause loss of control or kickback.
• Do not attach a saw chain woodcarving blade or toothed
saw blade. Such blades create frequent kickback and loss
of control.
Safety Warnings Specific for Grinding and Abrasive
Cutting-Off Operations
• Use only wheel types that are recommended for your
power tool and the specific guard designed for the selected
wheel. Wheels for which the power tool was not designed cannot
be adequately guarded and are unsafe.
• The grinding surface of centre depressed wheels must
be mounted below the plane of the guard lip. An improperly
mounted wheel that projects through the plane of the guard lip
cannot be adequately protected.
• The guard must be securely attached to the power tool
and positioned for maximum safety, so the least amount
of wheel is exposed towards the operator. The guard helps to
protect the operator from broken wheel fragments, accidental
contact with wheel and sparks that could ignite clothing.
• Wheels must be used only for recommended applications.
For example: do not grind with the side of cut-off wheel.
Abrasive cut-off wheels are intended for peripheral grinding, side
forces applied to these wheels may cause them to shatter.
• Always use undamaged wheel flanges that are of correct
size and shape for your selected wheel. Proper wheel flanges
support the wheel thus reducing the possibility of wheel breakage.
