Keep work area clean and well lit. Cluttered and dark areas invite to accidents. Recommended by the manufacturer Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite dust or fumes. Further information see Page 26 Illustrated or described accessories are not necessarily included in the scope of delivery Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control. Technical modifications reserved Electrical safety Especially important note for safety. Always follow this note, otherwise it could result in severe injury. Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock. Warning of dangerous electrical voltage WS-EN / 0909 Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your EN body is grounded. Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock. Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations. Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock. Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts. When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock. If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock. Personal safety Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.

Such preventive safety measures reduce the risk of starting the power tool accidentally. Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users. Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tools operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools. Safety rules 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 accordance with these instructions and in the manner intended for the particular type of power tool, 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. English 19 The outside diameter and the thickness of your accessory must be within the capacity rating of your power tool. Incorrectly sized accessories cannot be ade- EN quately guarded or controlled. The arbour size of wheels, flanges, backing pads or any other accessory must properly fit the spindle of the power tool. Accessories with arbour 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. Service Have your power tool serviced by a qualified repair person using only original spare parts. This will ensure that the safety of the power tool is maintained. Machine-specific Safety Warnings Safety instructions for grinding, sanding with sanding discs, working with wire brushes and abrasive cutting-off operations This Power tool is intended to function as a grinder, wire bruch, polisher or cut-off tool. Read al safety warnings, instructions, illustations and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury. This power tool is not recommended for polishing. Operations for which the power tool was not designed may create a hazard and cause personal injury. Do not use accessories which are not specifically designed and recommended by the tool manufacturer. Just because the 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. Accessories running faster than their rated spees can break and fly apart. 1 min Do not use a damaged accessory. Before each use inspect the accessory such as abrasive wheels for chips and cracks, backing pad for cracks, tear or excess wear, wire brush for loose or cracked wires. If power tool or accessory is dropped, inspect for damage or install an undamaged accessory. After inspecting and installing 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 minute. Damaged accessories will normally break apart during this test time. Wear personal protective equipment. Depending o application, use face shield, safety goggles or safety glasses. As appropriate, wear dust mask, hearing protectors, gloves and workshop apron capable of stopping small abrasive or workpiece fragments. The eye protection 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. WS-EN / 0909 Safety rules 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 accessory may contact hidden wiring or its own cord. Cutting accessory contacting a “live“ wire may make exposed metal parts of the power tool “live“ and shock the operator. 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 accessory. Never lay the power tool down until the accessory has come to a complete stop. The spinning accessory 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, fulling 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 accumulation of powdered metal may cause electrical hazards. Do not operate the power tool near flammable materials. Sparks could ignite these materials. Do not use accessories that require liquid coolants. Using water or other liquid coolants may result in electrocution or shock. Kickback and Related Warnings Kickback is a sudden reaction to a pinched or snagged rotating wheel, backing pad, brush or any other accessory. Pinching or snagging causes rapid stalling of the rotating accessory which in turn causes the uncontrolled power tool to be WS-EN / 0909 forced in the direction opposite of the accessory‘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 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. Always use auxiliary handle, if provided, for maximum control over kickback or torque reaction during start-up. The operator can control torque or kickback forces, if proper precautions are taken. Never place your hand near the rotating accessory. Accessory may kickback over your hand. Do not position your body in the area where power tool will move if kickback occurs. Kickback will probel the tool in direction opposite to the wheel‘s movement at the point of snagging. Use special care when working corners, sharp edges etc. Avoid bouncing and snagging the accessory. Corners, sharp edges or bouncing have a tendency to snag the rotating accessory and cause loss of control or kickback. Do not attach a saw chain woodcarving blade or toothed saw blade. Such blades create frequent kickback and loss of control. Safety Warnings Specific for Grinding and Abrasive Cutting-Off Operations Use only wheel types that are recommended for your power tool and the specific guard designed for the selected wheel. Wheels for which the power tool was not designed cannot be adequately guarded and are unsafe. Safety rules The guard must be securely attached to the power tool and positioned for maximum safety, so the least amount of wheel is exposed towards the operator. The guard helps to protect operator from broken wheel fragments and accidental contact with wheel. Wheels must be used only for recommended applications. 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 correct size and shape for your selected wheel. Proper wheel flanges support the wheel thus reducing the possibility of wheel breakage. Flanges for cut-off wheels may be different from grinding wheel flanges. English 21 Do not restart the cutting operation in the workpiece. Let the wheel reach full speed and carefully reenter the cut. The wheel may bind, walk up or kickback it the EN power tool is restarted in the workpiece. Support panels or any oversized workpiece to minimize the risk of wheel pinching and kickback. Large workpieces tend to sag under their own weight. Support must be placed under the workpiece near the line of cut and near the edge of the workpiece on both sides of the wheel. Use extra caution when making a “pocket cut“ into existing walls or other blind areas. The protruding wheel may cut gas or water pipes, electrical wiring or objects that can cause kickback. Safety warnings specific for sanding operations Do not use worn down wheels from larger power tools. Wheel intended für larger power tool is not suitable for the higher speed of a smaller tool and may burst. Do not use excessively oversized sanding disc paper. Follow manufacturers recommendations, when selecting sanding paper. Larger sanding paper extending beyond the sanding pad presents a laceration hazard and may cause snagging, tearing of the disc, or kickback. Additional safety instructions for abrasive cutting-off operations Safety Warnings Specific Brushing Operations Do not “jam“ the cut-off wheel or apply excessive pressure. Do not attempt to make an excessive depth of cut. Overstressing the wheel increases the loading and susceptibility to twisting or binding of the wheel in the cut and the possibility of kickback or wheel breakage. Be aware that wire bristles are thrown by the brush even during ordinary operation. Do not overstress the wires by applying excessive load to the brush. The wire bristles can easily penetrate light clothing and/or skin. Do not position your body in line with and behind the rotationg wheel. When the wheel, at the point of operation, is moving away from your body, the possible kickback may propel the spinning wheel and the power tool directly at you. When wheel is binding or when interrupting a cut for any reason, switch off the power tool and hold the power tool motionless until the wheel comes to a complete stop. Never attempt to remove the cutoff wheel from the cut while the wheel is in motion otherwise kickback may occur. Investigate and take corrective action to eliminate the cause of wheel binding. for Wire If the use of a guard is recommended for wire brushing, do not allow any interference of the wire wheel or brush with the guard. Wire wheel or brush may expand in diameter due to work load and centrifugal forces. Additional warnings Wear protective glasses and hearing protection. Use suitable detectors to determine if utility lines are hidden in the work area or call the local utility company for assistance. Contact with electric lines can lead to fire and electric shock. Damaging a gas line can lead to WS-EN / 0909 explosion. Penetrating a water line causes property damage or may cause an electric shock. EN Always use the protective devices prescribed for the respective application. Protective devices which are unsuitable for the application do not adequately guard the wheel. During operation, always ensure that the mains and extension cable is to the rear away from the device. This prevents anyone from tripping over the cable while working. When working with the machine, always hold it firmly with both hands and provide for a secure stance. The power tool is guided more secure with both hands. Secure the workpiece. A workpiece clamped with clamping devices or in a vice is held more secure than by hand. SiO2 Do not work on stone containing crystalline silica (SiO2). This will produce dust which is dangerous to your health. Do not work on materials containing asbestos. Asbestos is considered carcinogenic! Take protective measures if there is danger of formation of combustible or explosive dust during operation that can be hazardous to health. Example: Some dusts can be carcinogenic. Wear a dust mask and work with a dust/chip extraction unit, if possible to connect. Keep your workplace clean. Blends of materials are particularly dangerous. Dust from light alloys can burn or explode. Do not clamp the machine into a vice. A vice does not have suitable protective devices and thus causes an increased risk of injury. Tools not in use must be locked away safely in a dry place out of the reach of children. To mark the machine, do not drill into the housing. The protective insulation would be bridged. Use stickers. WS-EN / 0909 Never use the machine with a damaged cable. Do not touch the damaged cable and pull the mains plug when the cable gets damaged during operation. Damaged cables increase the risk of electric shock. Residual risk. Although this information sheet and the operating manuals for our electrical tools contain extensive instructions on safe working with electrical tools, every electrical tool involves certain residual risks that cannot be completely prevented through safety mechanisms. Therefore, electrical tools must always be operated with the necessary caution.

Grinding and cutting discs become very hot while working; do not touch until they have cooled. Wear protective glasses and hearing protection. Do not strain the machine so heavily that it comes to a standstill. WS-EN / 0909 Rough Grinding The best roughing results are achieved when setting the machine at an angle of 30° to 40°. -WARNINGNever use a cutting disc for roughing. Move the machine back and forth with moderate pressure. In this manner, the workpiece will not become too hot, does not discolour and no grooves are formed. Abrasive cutting-off operations For cutting, always work with the protection guard for cutting 6. Do not exert pressure onto the cutting disc, tilt or oscillate the machine. Always work in reverse rotation with the angle grinder There is a danger of the grinder jumping out of the cut in an uncontrolled manner. When cutting, work with moderate feed, adapted to the material being cut. Rule of thumb: the harder the material, the slower the speed. Do not reduce the speed of running down cutting discs by applying sideward pressure. Cutting Metall For cutting metal, always work with the protection guard for cutting 6. Cutting Stone The machine may be used only for dry cutting/ grinding. For cutting stone, it is best to use a diamond cutting disc. Working with a diamond cutting disc For cutting expecially hard material, e. g., concrete with high pebble content, the diamond cutting disc can overheat and become damaged as a result. This is clearly indicated by circular sparking, rotating with the diamond cutting disc. In this case, interrupt the cutting process and allow the diamond cutting disc to cool by running the machine for a short time at maximum speed with no load. Noticeable decreasing work progress and circular sparking are indications of a diamond cutting disc that has become dull. Briefly cutting into abrasive material (e. g. lime-sand brick) can resharpen the disc again. Working with a cup-shaped wire brush Use the cup-shaped wire brush to derust and clean metal and stone and to prepare surfaces for soldering and welding work. Avoid motor overload If the motor housing of the angle grinder becomes hot, the load on the motor is too high (danger of the motor burning). Operate the machine at no-load speed to allow the motor to cool. Turning the machine handle (Option) Before carrying out any work on the machine, pull the mains plug. Bow-shaped handle 4 can be rotated 90° to the left and to the right in the direction of motor housing 3. This allows you to position On/Off switch II more conveniently for special working conditions; e. g. for abrasive cutting-off operations or for lefthanded people. Press handle unlocking device VII at at the same time, rotate bow-shaped handle 4 to the desired position until it engages. -WARNINGDo not use the tool unless the rotatable handle is secured.

purchase receipt together with the device to us or to the relevant service centre.

the sales agreement should we fail to eliminate any defects within a reasonable period of time.

8. This does not exclude compensation claims in accordance with §§ 463, 480 Para. 2, 635 BGB caused

by the failure of assured properties.

9. The provisions defined in Items 7 and 8 only apply to

the Federal Republic of Germany. Accessoires
