1 609 92A 0Y3 | (4.2.15) Bosch Power Tools

Keep cutting tools sharp and clean. Properly maintained

cutting tools with sharp cutting edges are less likely to bind

and are easier to control.

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

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

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.

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.

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.

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.

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.

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.

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.

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.

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

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, the cord may be cut or snagged and your 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 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 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.

Kickback and related warnings

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.

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.
