Bosch Power Tools 1 619 P11 460 | (26.11.13)

 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, sanding drums or any other

accessory must properly fit the spindle or collet of the

power tool. Accessories that do not match the mounting

hardware of the power tool will run out of balance, vibrate

excessively and may cause loss of control.

 Mandrel mounted wheels, sanding drums, cutters or

other accessories must be fully inserted into the collet

or chuck. If the mandrel is insufficiently held and/or the

overhang of the wheel is too long, the mounted wheel may

become loose and ejected at high velocity.

 Do not use a damaged accessory. Before each use in-

spect the accessory such as abrasive wheels for chips

and cracks, sanding drum 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 min-

ute. 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 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 power tool by insulated gripping surfaces only,

when performing an operation where the cutting ac-

cessory may contact hidden wiring. Cutting accessory

contacting a “live” wire may make exposed metal parts of

the power tool “live” and shock the operator.

 Always hold the tool firmly in your hand(s) during the

start-up. The reaction torque of the motor, as it acceler-

ates to full speed, can cause the tool to twist.

 Use clamps to support workpiece whenever practical.

Never hold a small workpiece in one hand and the tool

in the other hand while in use. Clamping a small work-

piece allows you to use both hands to control the tool.

Round material such as dowel rods, pipes or tubing have a

tendency to roll while being cut, and may cause the bit to

bind or jump toward you.

 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.

 After changing the bits or making any adjustments,

make sure the collet nut, chuck or any other adjust-

ment devices are securely tightened. Loose adjustment

devices can unexpectedly shift, causing loss of control,

loose rotating components will be violently thrown.

 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 accumu-

lation 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

 Kickback is a sudden reaction to a pinched or snagged rotat-

ing wheel, backing pad, brush or any other accessory.

Pinching or snagging causes rapid stalling of the rotating ac-

cessory which in turn causes the uncontrolled power tool to

be forced in the direction opposite of the accessory’s rota-

tion 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 di-

rection of the wheel’s movement at the point of pinching.

Abrasive wheels may also break under these conditions.

Kickback is the result of power tool misuse and/or incorrect

operating procedures or conditions and can be avoided 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.

The operator can control kickback forces, if proper precau-

tions are taken.

 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 use a toothed saw blade. Such blades create fre-

quent kickback and loss of control over the power tool.

 Always feed the bit into the material in the same direc-

tion as the cutting edge is exiting from the material

(which is the same direction as the chips are thrown).

Feeding the tool in the wrong direction causes the cutting

edge of the bit to climb out of the work and pull the tool in

the direction of this feed.

 When using rotary files, cut-off wheels, high-speed cut-

ters or tungsten carbide cutters, always have the work

securely clamped. These wheels will grab if they become

slightly canted in the groove, and can kickback. When a

cut-off wheel grabs, the wheel itself usually breaks. When

the rotary file, high-speed cutter or tungsten carbide cut-

ter grab, it may jump from the groove and you could lose

control of the tool.
