Bosch Power Tools

f

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.

f

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.

f

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.

f

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.

f

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.

f

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.

f

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.

f

Do not operate the power tool near flammable materi-

als. 

Sparks could ignite these materials.

f

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.

f

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.

f

Never place your hand near the rotating accessory. 

Ac-

cessory may kickback over your hand.

f

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.

f

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.

f

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.

Safety warnings specific for Grinding and 

Abrasive Cutting-Off operations

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.

f

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.

f

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.

f

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.

f

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.

Additional safety warnings specific for abrasive 

cutting off operations

f

Do not “jam” the cut-off wheel or apply excessive pres-

sure. Do not attempt to make an excessive depth of cut. 

Overstressing the wheel increases the loading and suscep-

tibility to twisting or binding of the wheel in the cut and the 

possibility of kickback or wheel breakage.
