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 acces-
sory 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, position yourself and bystand-
ers 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. Depending on
application, use face shield, safety goggles or safety
glasses. Where appropriate, wear dust mask, hearing
protectors, gloves and workshop apron capable of stop-
ping small abrasive or workpiece fragments. The eye
protection must be capable of stopping flying debris
generated by various operations. The dust mask or res-
pirator must be capable of filtrating particles generated
by your operation. Prolonged exposure to high inten-
sity noise may cause hearing loss.
Keep bystanders a safe distance away from work area.
Anyone entering the work area must wear personal pro-
tective equipment. Fragments of workpiece or of a bro-
ken 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 acces-
sory 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 of the power tool, 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 materi-
als. Sparks could ignite these materials.
Do not use accessories that require liquid coolants.
Using water or other liquid coolants may result in elec-
trocution or shock.
Kickback and related warnings
Kickback is a sudden reaction to a pinched or snagged
rotating wheel, backing pad, brush or any other acces-
sory. Pinching or snagging causes rapid stalling of the
rotating accessory which in turn causes the uncon-
trolledpower tool to be forced in the direction oppo-
site 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 oper-
ator, 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 kick-
back 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. Cor-
ners, sharp edges or bouncing have a tendency to snag
the rotating accessory and cause loss of control or kick-
back.
Do not attach a saw chain woodcarving blade or
toothed saw blade. Such blades create frequent kick-
back and loss of control over the power tool.
Safety warnings specific for grinding and abra-
sive 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.
