Read all safety warningsand all instructions. Failure to followthe warnings and instructions may resultin electric shock, fire and/or seriousinjury.SAVE ALL WARNINGS AND INSTRUCTIONSFOR FUTURE REFERENCEThe term “power tool” in the warnings refers to yourmains-operated (corded) power tool or batteryoperated(cordless) power tool.1) WORK AREA SAFETYa) Keep work area clean and well lit.Cluttered or dark areas invite accidents.b) Do not operate power tools in explosiveatmospheres, such as in the presence offlammable liquids, gases or dust. Powertools create sparks which may ignite the dustor fumes.c) Keep children and bystanders away whileoperating a power tool. Distractions cancause you to lose control.2) ELECTRICAL SAFETYa) Power tool plugs must match the outlet.Never modify the plug in any way. Donot use any adapter plugs with earthed(grounded) power tools. Unmodified plugsand matching outlets will reduce risk ofelectric shock.b) Avoid body contact with earthed orgrounded surfaces such as pipes,radiators, ranges and refrigerators. Thereis an increased risk of electric shock if yourbody is earthed or grounded.c) Do not expose power tools to rain or wetconditions. Water entering a power tool willincrease the risk of electric shock.d) Do not abuse the cord. Never use thecord for carrying, pulling or unpluggingthe power tool. Keep cord away fromheat, oil, sharp edges or moving parts.Damaged or entangled cords increase therisk of electric shock.e) When operating a power tool outdoors,use an extension cord suitable for outdooruse. Use of a cord suitable for outdoor usereduces the risk of electric shock.f) If operating a power tool in a damplocation is unavoidable, use a residualcurrent device (RCD) protected supply.Use of an RCD reduces the risk of electricshock.3) PERSONAL SAFETYa) Stay alert, watch what you are doing anduse common sense when operating apower tool. Do not use a power tool whileyou are tired or under the influence ofdrugs, alcohol or medication. A moment ofinattention while operating power tools mayresult in serious personal injury.b) Use personal protective equipment.Always wear eye protection. Protectiveequipment such as dust mask, non-skidsafety shoes, hard hat, or hearing protectionused for appropriate conditions will reducepersonal injuries.c) Prevent unintentional starting. Ensurethe switch is in the off position beforeconnecting to power source and/orbattery pack, picking up or carrying thetool. Carrying power tools with your fingeron the switch or energising power tools thathave the switch on invites accidents.6

ENGLISHd) Remove any adjusting key or wrenchbefore turning the power tool on. Awrench or a key left attached to a rotatingpart of the power tool may result in personalinjury.e) Do not overreach. Keep properfooting and balance at all times. Thisenables better control of the power tool inunexpected situations.f) Dress properly. Do not wear looseclothing or jewellery. Keep your hair,clothing and gloves away from movingparts. Loose clothes, jewellery or long haircan be caught in moving parts.g) If devices are provided for the connectionof dust extraction and collection facilities,ensure these are connected and properlyused. Use of dust collection can reducedust-related hazards.4) POWER TOOL USE AND CAREa) Do not force the power tool. Use thecorrect power tool for your application.The correct power tool will do the jobbetter and safer at the rate for which itwas designed.b) Do not use the power tool if the switchdoes not turn it on and off. Any powertool that cannot be controlled with the switchis dangerous and must be repaired.c) Disconnect the plug from the powersource and/or the battery pack fromthe power tool before making anyadjustments, changing accessories, orstoring power tools. Such preventive safetymeasures reduce the risk of starting thepower tool accidentally.d) Store idle power tools out of the reachof children and do not allow personsunfamiliar with the power tool or theseinstructions to operate the power tool.Power tools are dangerous in the hands ofuntrained users.e) Maintain power tools. Check formisalignment or binding of moving parts,breakage of parts and any other conditionthat may affect the power tool’s operation.If damaged, have the power tool repairedbefore use. Many accidents are caused bypoorly maintained power tools.f) Keep cutting tools sharp and clean.Properly maintained cutting tools with sharpcutting edges are less likely to bind and areeasier to control.g) Use the power tool, accessories andtool bits etc., in accordance with theseinstructions taking into account theworking conditions and the work tobe performed. Use of the power tool foroperations different from those intendedcould result in a hazardous situation.5) SERVICEa) Have your power tool serviced by aqualified repair person using only identicalreplacement parts. This will ensure that thesafety of the power tool is maintained.ADDITIONAL SPECIFIC SAFETY RULESSafety Instructions for All Operationsa) This power tool is intended to functionas a grinder, sander, wire brush, polisheror cut-off tool. Read all safety warnings,instructions, illustrations and specificationsprovided with this power tool. Failure to followall instructions listed below may result in electricshock, fire and/or serious injury.b) Do not use accessories which are notspecifically designed and recommendedby the tool manufacturer. Just because theaccessory can be attached to your power tool,it does not assure safe operation.c) The rated speed of the accessory must be atleast equal to the maximum speed markedon the power tool. Accessories running fasterthan their rated speed can break and fly apart.d) The outside diameter and the thickness ofyour accessory must be within the capacityrating of your power tool. Incorrectly sizedaccessories cannon be adequately guarded orcontrolled.e) The arbour size of wheels, flanges, backingpads or any other accessory must properlyfit the spindle of the power tool. Accessorieswith arbour holes that do not match themounting hardware of the power tool will runout of balance, vibrate excessively and maycause loss of control.f) Do not use a damaged accessory. Beforeeach use inspect the accessory such asabrasive wheel for chips and cracks, backingpad for cracks, tear or excess wear, wirebrush for loose or cracked wires. If powertool or accessory is dropped, inspect fordamage or install an undamaged accessory.After inspecting and installing an accessory,position yourself and bystanders away fromthe plane of the rotating accessory and runthe power tool at maximum no-load speedfor one minute. Damaged accessories willnormally break apart during this test time.7

ENGLISHg) Wear personal protective equipment.Depending on application, use faceshield, safety goggles or safety glasses.As appropriate, wear dust mask, hearingprotectors, gloves and workshop aproncapable of stopping small abrasive orworkpiece fragments. The eye protection mustbe capable of stopping flying debris generatedby various operations. The dust mask orrespirator must be capable of filtrating particlesgenerated by your operation. Prolongedexposure to high intensity noise may causehearing loss.h) Keep bystanders a safe distance away fromwork area. Anyone entering the work areamust wear personal protective equipment.Fragments of workpiece or of a brokenaccessory may fly away and cause injurybeyond immediate area of operation.i) Hold power tool by insulated grippingsurfaces only, when performing an operationwhere the cutting accessory may contacthidden wiring or its own cord. Cuttingaccessory contacting a “live” wire may makeexposed metal parts of the power tool “live” andshock the operator.j) Position the cord clear of the spinningaccessory. If you lose control, the cord may becut or snagged and your hand or arm may bepulled into the spinning accessory.k) Never lay the power tool down until theaccessory has come to a complete stop. Thespinning accessory may grab the surface andpull the power tool out of your control.l) Do not run the power tool while carrying it atyour side. Accidental contact with the spinningaccessory could snag your clothing, pulling theaccessory into your body.m) Regularly clean the power tool’s air vents.The motor’s fan will draw the dust insidethe housing and excessive accumulation ofpowdered metal may cause electrical hazards.n) Do not operate the power tool nearflammable materials. Sparks could ignite thesematerials.o) Do not use accessories that require liquidcoolants. Using water or other liquid coolantsmay result in electrocution or shock.FURTHER SAFETY INSTRUCTIONSFOR ALL OPERATIONSCauses and Operator Preventionof KickbackKickback is a sudden reaction to a pinched orsnagged rotating wheel, backing pad, brush orany other accessory. Pinching or snagging causesrapid stalling of the rotating accessory which in turncauses the uncontrolled power tool to be forced inthe direction opposite of the accessory’s rotation atthe point of the binding.For example, if an abrasive wheel is snagged orpinched by the workpiece, the edge of the wheelthat is entering into the pinch point can dig into thesurface of the material causing the wheel to climbout or kick out. The wheel may either jump towardor away from the operator, depending on directionof the wheel’s movement at the point of pinching.Abrasive wheels may also break under theseconditions.Kickback is the result of tool misuse and/or incorrectoperating procedures or conditions and can beavoided by taking proper precautions as givenbelow:a) Maintain a firm grip on the power tool andposition your body and arm to allow you toresist kickback forces. Always use auxiliaryhandle, if provided, for maximum controlover kickback or torque reaction during startup. The operator can control torque reaction orkickback forces, if proper precautions are taken.b) Never place your hand near the rotatingaccessory. Accessory may kickback over yourhand.c) Do not position your body in the area wherepower tool will move if kickback occurs.Kickback will propel the tool in directionopposite to the wheel’s movement at the pointof snagging.d) Use special care when working corners,sharp edges etc. Avoid bouncing andsnagging the accessory. Corners, sharpedges or bouncing have a tendency to snag therotating accessory and cause loss of control orkickback.e) Do not attach a saw chain woodcarvingblade or toothed saw blade. Such bladescreate frequent kickback and loss of control.8

ENGLISHSafety Warnings Specific forGrinding and Abrasive Cutting-OffOperationsa) Use only wheel types that are recommendedfor your power tool and the specific guarddesigned for the selected wheel. Wheels forwhich the power tool was not designed cannotbe adequately guarded and are unsafe.b) The guard must be securely attached to thepower tool and positioned for maximumsafety, so the least amount of wheel isexposed towards the operator. The guardhelps to protect operator from broken wheelfragments and accidental contact with wheel.c) Wheels must be used only for recommendedapplications. For example: do not grind withthe side of cut-off wheel. Abrasive cut-offwheels are intended for peripheral grinding, sideforces applied to these wheels may cause themto shatter.d) Always use undamaged wheel flangesthat are of correct size and shape for yourselected wheel. Proper wheel flanges supportthe wheel thus reducing the possibility of wheelbreakage. Flanges for cut-off wheels may bedifferent from grinding wheel flanges.e) Do not use worn down wheels from largerpower tools. Wheel intended for larger powertool is not suitable for the higher speed of asmaller tool and may burst.Additional Safety Warnings Specificfor Abrasive Cutting-Off Operationsa) Do not “jam” the cut-off wheel or applyexcessive pressure. Do not attempt to makean excessive depth of cut. Overstressing thewheel increases the loading and susceptibility totwisting or binding of the wheel in the cut andthe possibility of kickback or wheel breakage.b) Do not position your body in line with andbehind the rotating wheel. When the wheel,at the point of operations, is moving away fromyour body, the possible kickback may propel thespinning wheel and the power tool directly atyou.c) When wheel is binding or when interruptinga cut for any reason, switch off the powertool and hold the power tool motionlessuntil the wheel comes to a complete stop.Never attempt to remove the cut-off wheelfrom the cut while the wheel is in motionotherwise kickback may occur. Investigateand take corrective action to eliminate the causeof wheel binding.d) Do not restart the cutting operation in theworkpiece. Let the wheel reach full speedand carefully reenter the cut. The wheel maybind, walk up or kickback if the power too isrestated in the workpiece.e) Support panels or any oversized workpieceto minimize the risk of wheel pinching andkickback. Large workpieces tend to sag undertheir own weight. Supports must be placedunder the workpiece near the line of cut andnear the edge of the workpiece on both sides ofthe wheel.f) Use extra caution when making a “pocketcut” into existing walls or other blind areas.The protruding wheel may cut gas or waterpipes, electrical wiring or objects that can causekickback.Safety Warnings Specific for SandingOperations(D28410, D28413, D28422 only)a) Do not use excessively oversized sandingdisc paper. Follow manufacturer'srecommendations, when selecting sandingpaper. Larger sanding paper extending beyondthe sanding pad presents a laceration hazardand may cause snagging, tearing of the discor kickback.Safety Warnings Specific forPolishing Operations(D28410, D28413, D28422 only)a) Do not allow any loose portion of thepolishing bonnet or its attachment stringsto spin freely. Tuck away or trim any looseattachment strings. Loose and spinningattachment strings can entangle your fingers orsnag on the workpiece.Safety Warnings Specific for WireBrushing Operationsa) Be aware that wire bristles are thrown bythe brush even during ordinary operation.Do not overstress the wires by applyingexcessive load to the brush. The wire bristlescan easily penetrate light clothing and/or skin.b) If the use of a guard is recommended forwire brushing, do not allow any interferenceof the wire wheel or brush with the guard.Wire wheel or brush may expand in diameterdue to work and centrifugal forces.9
