tool, it does not assure safe operation.
Therated speed oftheaccessorymustbe atleastequal
to the maximum speed marked on the power tool. Ac-
cessories 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 grind-
er spindle thread. For accessories mounted by flanges,
the arbour hole of the accessory must fit the locating di-
ameter 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 in-
spect 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 in-
stall an undamaged accessory. After inspecting and in-
stallinganaccessory,positionyourselfandbystanders
away from the plane of the rotating accessory and run
the power tool at maximum no-load speed for one min-
ute.Damagedaccessorieswillnormallybreakapartduring
this test time.
Wear personal protective equipment. Depending on
application, use face shield, safety goggles or safety
glasses. As appropriate, wear dust mask, hearing pro-
tectors, gloves and shop apron capable of stopping
small abrasive or workpiece fragments. The eye protec-
tion must be capable of stopping flying debris generated

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 on-
ly, when performing an operation where the cutting ac-
cessorymay contact hiddenwiring or its own cord. Cut-
ting accessory contacting a “live” wire may make exposed
metal parts of the power tool “live” and could give the op-
erator an electric shock.

ing water or other liquid coolants may result in electrocu-
tion or shock.
Kickback and related warnings
Kickback is a sudden reactionto a pinched or snagged rotat-
ing wheel, backing pad, brush or any other accessory.
Pinching or snagging causes rapid stalling of the rotating ac-
cessory which in turn causes the uncontrolled power tool to
be forced in the direction opposite of theaccessory’s rota-
tion at the point of the binding.
For example, if an abrasive wheel is snagged or pinched by
theworkpiece,theedgeofthewheelthatis enteringintothe
pinch point can dig into thesurface 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 di-
rection 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.
