Bosch Power Tools

If damaged, have the power tool repaired before use. 

Many accidents are caused by poorly maintained power 

tools.

f

Keep cutting tools sharp and clean. 

Properly maintained 

cutting tools with sharp cutting edges are less likely to bind 

and are easier to control.

f

Use the power tool, accessories and tool bits etc. in ac-

cordance with these instructions, taking into account 

the working conditions and the work to be performed. 

Use of the power tool for operations different from those 

intended could result in a hazardous situation.

Service

f

Have your power tool serviced by a qualified repair per-

son using only identical replacement parts. 

This will en-

sure that the safety of the power tool is maintained.

Cut-off machine safety warnings

f

The guard provided with the tool must be securely at-

tached to the power tool and positioned for maximum 

safety, so the least amount of wheel is exposed to-

wards the operator. Position yourself and bystanders 

away from the plane of the rotating wheel. 

The guard 

helps to protect operator from broken wheel fragments 

and accidental contact with wheel.

f

Use only diamond cut-off wheels for your power tool. 

Just because an accessory can be attached to your power 

tool, it does not assure safe operation.

f

The rated speed of the accessory must be at least equal 

to the maximum speed marked on the power tool. 

Ac-

cessories running faster than their rated speed can break 

and fly apart.

f

Wheels must be used only for recommended applica-

tions. For example: do not grind with the side of 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 diameter for your selected wheel. 

Proper wheel 

flanges support the wheel thus reducing the possibility of 

wheel breakage.

f

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.

f

The arbour size of wheels and flanges must properly fit 

the spindle of the power tool. 

Wheels and flanges with ar-

bour holes that do not match the mounting hardware of the 

power tool will run out of balance, vibrate excessively and 

may cause loss of control.

f

Do not use damaged wheels. Before each use, inspect 

the wheels for chips and cracks. If power tool or wheel 

is dropped, inspect for damage or install an undam-

aged wheel. After inspecting and installing the wheel, 

position yourself and bystanders away from the plane 

of the rotating wheel and run the power tool at maxi-

mum no load speed for one minute. 

Damaged wheels will 

normally break apart during this test time.

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, the cord may be cut or snagged and your hand 

or arm may be pulled into the spinning wheel.

f

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.

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. Pinching or snagging causes rapid stalling of 

the rotating wheel which in turn causes the uncontrolled 

power tool to be forced in the direction opposite of the 

wheel’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.
