3 609 929 C82 | (21.3.14) Bosch Power Tools
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
matchthemountinghardwareof thepowertoolwillrunout
of balance, vibrate excessively and may cause loss of con-
trol.
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,positionyourselfand bystanders
away from the plane of the rotating accessory and run
the power tool at maximum no-load speed for one min-
ute.Damagedaccessorieswillnormallybreakapart during
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
byvariousoperations.Thedustmaskorrespiratormust be
capable offiltrating particlesgeneratedby youroperation.
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 ac-
cessory may contact hidden wiring or itsown 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.
Position the cord clear of thespinning accessory.If you
losecontrol,the cordmay be cutorsnaggedandyour hand
or arm may be pulled into the spinning wheel.
Never lay the power tool down until the accessory has
come to a complete stop. The spinning wheel may grab
the surface and pull the power tool out of your control.
Do not run the power tool while carrying it at yourside.
Accidentalcontact with thespinning accessory couldsnag
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 ac-
cumulation of powdered metal may cause electrical haz-
ards.
Do not operate the power tool near flammable materi-
als. Sparks could ignite these materials.
Do not use accessories that require liquid coolants. Us-
ing water or other liquid coolants may result in electrocu-
tion or shock.
Kickback and related warnings
Kickback is a sudden reaction to a pinched or snagged ro-
tating 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 accesso-
ry’s rotation at the point of the binding.
Forexample, ifanabrasive wheelis snagged or pinchedby
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 pinch-
ing. Abrasive wheels may also break under these condi-
tions.
Kickback is the result of power tool misuse and/or incor-
rect operating procedures or conditions and can be avoid-
ed by taking proper precautions as given below.
Maintainafirmgrip on the powertoolandpositionyour
body and arm to allow you to resist kickback forces. Al-
ways 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. Ac-
cessory 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 orbouncinghave atendency tosnag the
rotating accessory and cause loss of control or kickback.
Do not attach a saw chain woodcarving blade or
toothedsaw blade.Such bladescreate frequentkickback
and loss of control.
Additional safety instructions for grinding
Use only wheel types that are recommended for your
power tool and the specific guard designed for the se-
lectedwheel. Wheelsforwhich thepower tool wasnotde-
signed cannot be adequately guarded and are unsafe.
The grinding surface of the centre depressed wheels
must be mounted below the plane of the guard lip. An
improperlymountedwheelthatprojectsthrough theplane
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 operator from broken wheel frag-
ments, accidental contact with wheeland sparks that
could ignite clothing.
