Bosch Power Tools

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-

stalling 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.

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 workshop apron capable of stop-

ping small abrasive or workpiece fragments. The eye

protection must be capable of stopping flying debris gen-

erated 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.

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-

cessory may contact hidden wiring 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.

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 spin-

ning 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 accu-

mulation 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. Us-

ing water or other liquid coolants may result in electrocu-

tion or shock.

Kickback and related warnings
f

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.

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 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.

Maintain a firm grip on the power tool and position your

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 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 over the power tool.

Additional safety instructions for grinding
f

Use only wheel types that are recommended for your

power tool and the specific guard designed for the se-

lected wheel. Wheels for which the power tool was not de-

signed cannot be adequately guarded and are unsafe.

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 wheel and sparks that

could ignite clothing.

Wheels must be used only for recommended applica-

tions. For example: do not grind with the side of the

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 cor-

rect size and shape for your selected wheel. Proper

wheel flanges support the wheel thus reducing the possi-

bility of wheel breakage. Flanges for cut-off wheels may be

different from grinding wheel flanges.

Do not use worn down wheels from larger power tools.

Wheels intended for larger power tools are not suitable for

the higher speed of a smaller tool and may burst.
