24 | Englishu Keep bystanders a safe distance away from work area.Anyone entering the work area must wear personalprotective equipment. Fragments of workpiece or of abroken accessory may fly away and cause injury beyondimmediate area of operation.u Hold the power tool by insulated gripping surfacesonly, when performing an operation where the cuttingaccessory may contact hidden wiring or its own cord.Cutting accessory contacting a "live" wire may make ex-posed metal parts of the power tool "live" and could givethe operator an electric shock.u Position the cord clear of the spinning accessory. Ifyou lose control, the cord may be cut or snagged and yourhand or arm may be pulled into the spinning accessory.u Never lay the power tool down until the accessory hascome to a complete stop. The spinning accessory maygrab the surface and pull the power tool out of your con-trol.u Do not run the power tool while carrying it at yourside. Accidental contact with the spinning accessorycould snag your clothing, pulling the accessory into yourbody.u Regularly clean the power tool’s air vents. The motor’sfan will draw the dust inside the housing and excessiveaccumulation of powdered metal may cause electricalhazards.u Do not operate the power tool near flammable materi-als. Sparks could ignite these materials.u Do not use accessories that require liquid coolants.Using water or other liquid coolants may result in electro-cution 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. Pinch-ing or snagging causes rapid stalling of the rotating access-ory which in turn causes the uncontrolled power tool to beforced in the direction opposite of the accessory’s rotationat the point of the binding.For example, if an abrasive wheel is snagged or pinched bythe workpiece, the edge of the wheel that is entering into thepinch point can dig into the surface of the material causingthe wheel to climb out or kick out. The wheel may eitherjump toward or away from the operator, depending on direc-tion of the wheel’s movement at the point of pinching. Abras-ive wheels may also break under these conditions.Kickback is the result of power tool misuse and/or incorrectoperating procedures or conditions and can be avoided bytaking proper precautions as given below.u Maintain a firm grip with both hands on the power tooland position your body and arms to allow you to resistkickback forces. Always use auxiliary handle, ifprovided, for maximum control over kickback ortorque reaction during start-up. The operator can con-trol torque reactions or kickback forces, if proper precau-tions are taken.u Never place your hand near the rotating accessory.Accessory may kickback over your hand.u Do not position your body in the area where powertool will move if kickback occurs. Kickback will propelthe tool in direction opposite to the wheel’s movement atthe point of snagging.u Use special care when working corners, sharp edges,etc. Avoid bouncing and snagging the accessory.Corners, sharp edges or bouncing have a tendency tosnag the rotating accessory and cause loss of control orkickback.u Do not attach a saw chain woodcarving blade, seg-mented diamond wheel with a peripheral gap greaterthan 10 mm or toothed saw blade. Such blades createfrequent kickback and loss of control.Safety warnings specific for grinding and cutting-offoperations:u Use only wheel types that are specified for your powertool and the specific guard designed for the selectedwheel. Wheels for which the power tool was not designedcannot be adequately guarded and are unsafe.u The grinding surface of centre depressed wheels mustbe mounted below the plane of the guard lip. An im-properly mounted wheel that projects through the planeof the guard lip cannot be adequately protected.u The guard must be securely attached to the power tooland positioned for maximum safety, so the leastamount of wheel is exposed towards the operator.The guard helps to protect the operator from brokenwheel fragments, accidental contact with wheel andsparks that could ignite clothing.u Wheels must be used only for specified applications.For example: do not grind with the side of cut-offwheel. Abrasive cut-off wheels are intended for peri-pheral grinding, side forces applied to these wheels maycause them to shatter.u Always use undamaged wheel flanges that are of cor-rect size and shape for your selected wheel. Properwheel flanges support the wheel thus reducing the pos-sibility of wheel breakage. Flanges for cut-off wheels maybe different from grinding wheel flanges.u Do not use worn down wheels from larger power tools.A wheel intended for larger power tool is not suitable forthe higher speed of a smaller tool and may burst.u When using dual purpose wheels always use the cor-rect guard for the application being performed. Failureto use the correct guard may not provide the desired levelof guarding, which could lead to serious injury.Additional safety warnings specific for cutting-offoperations:u Do not “jam” the cut-off wheel or apply excessivepressure. Do not attempt to make an excessive depthof cut. Overstressing the wheel increases the loadingand susceptibility to twisting or binding of the wheel inthe cut and the possibility of kickback or wheel breakage.u Do not position your body in line with and behind therotating wheel. When the wheel, at the point of opera-tion, is moving away from your body, the possible kick-1 609 92A 5RE | (16.02.2022) Bosch Power Tools
