2.1 General power tool safety warnings

WARNING Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury. Save all warnings and instructions for future reference. Work area safety ▶ Keep work area clean and well lit. Cluttered or dark areas invite accidents. ▶ 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 the dust or fumes. ▶ Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control. Electrical safety ▶ 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. ▶ Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded. ▶ Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock. ▶ 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. ▶ 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. ▶ Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries. Printed: 27.07.2017 | Doc-Nr: PUB / 5238733 / 000 / 0214 English ▶ Prevent unintentional starting. Ensure the switch is in the off‐position before connecting to power source, picking up or carrying the tool. Carrying power tools with your finger on the switch or energising power tools that have the switch on invites accidents. ▶ 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 overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations. ▶ 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. ▶ If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards. Power tool use and care ▶ Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed. ▶ Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired. ▶ Disconnect the plug from the power source from the power tool before making any adjustments, changing accessories, or storing power tools. 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 tool’s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained 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 accordance 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 person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.

2.2 General safety instructions applicable to grinding and polishing

▶ Do not use accessories not specifically intended and recommended for this power tool by the tool manufacturer. The fact that an accessory can be attached to the power tool does not necessarily mean that it can be used safely. ▶ 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 speed can disintegrate and fly apart. ▶ The outside diameter and the thickness of the accessory tool must be within the ranges stated for your power tool. Incorrectly sized accessory tools cannot be adequately guarded or controlled. ▶ Accessory tools with a threaded insert must match the thread of the drive spindle. Flange-mounted accessory tools must have a hole diameter matching the mandrel diameter of the flange. Accessory tools not correctly secured to the power tool rotate unevenly, vibrate excessively and can cause loss of control of the tool. ▶ Do not use damaged accessory tools. Check the condition of the accessory tool before each use, i.e. check abrasive discs for chips and cracks, and check backing pads for cracks, tears or excessive wear. If the power tool or accessory tool is dropped, inspect it for damage or use an undamaged accessory tool. After inspecting and installing an accessory tool, position yourself and bystanders away from the plane of the rotating tool and run the power tool at maximum no-load speed for one minute. If an accessory tool has been damaged it will usually break during this test period. ▶ Wear personal protective equipment. Wear a face shield, eye protection or safety goggles, as appropriate to the application. As appropriate, wear a dust mask, ear protection, protective gloves and a workshop apron to protect you from flying abrasive particles and fragments of the material you are working on. Make sure your eyes are protected against the flying debris created by various machining operations. The dust mask or respirator must be capable of filtering out dust particles resulting from use of the power tool. Prolonged exposure to high-intensity noise can cause hearing loss. Printed: 27.07.2017 | Doc-Nr: PUB / 5238733 / 000 / 02English 15 ▶ Keep bystanders a safe distance away from the work area. Anyone entering the work area must wear personal protective equipment. Fragments of the workpiece or of a broken accessory tool may fly off and cause injury beyond the immediate area of operation. ▶ Hold the power tool only by the insulated gripping surfaces when carrying out work in which the accessory tool can come into contact with concealed wiring or with the power tool's own supply cord. If the accessory tool comes into contact with a live wire, metal parts of the power tool can also become live, resulting in an electric shock. ▶ Keep the power cord well clear of rotating accessory tools. If you lose control, the power cord could be cut or snagged and your hand or arm pulled into contact with the rotating accessory tool. ▶ Never lay the power tool down before the accessory tool has come to a complete stop. If the rotating accessory tool is allowed to touch the surface on which you place the power tool, you could lose control of the power tool. ▶ Never start the power tool while carrying it around. Your clothing could be snagged by the rotating accessory tool, pulling the accessory tool into your body. ▶ Clean the ventilation slots on the power tool at regular intervals. The motor’s fan draws dust into the housing and a build-up of metallic dust can cause electrical hazards. ▶ Do not operate the power tool near flammable materials. Sparks could ignite these materials. ▶ Do not use accessory tools that require liquid coolants. Using water or other liquid coolants can cause electric shock. Kickback and the applicable safety instructions Kickback is the abrupt reaction to the sudden stalling of a pinched or snagged rotating disc, backing pad or other accessory tool. Pinching or snagging causes the rotating accessory tool to come to an abrupt stop. This causes an uncontrolled power tool to be forced in the direction opposite to the accessory tool’s direction of rotation at the point of binding. For example, if an abrasive disc is snagged or pinched by the workpiece, the edge of the disc entering the pinch point can dig into the surface of the material causing the disc to climb out or kick back. The disc then skips toward or away from the operator, depending on the disc’s direction of movement at the point of pinching. Abrasive discs can also break under these conditions. Kickback is the result of power tool misuse and/or incorrect operating procedures or conditions. It can be avoided by taking the proper precautions as described below. ▶ Maintain a firm grip on the power tool and position your body and arms to absorb kickback forces. Always use the auxiliary handle, if provided, for maximum control over kickback forces or torque reaction during start-up. By adopting suitable precautionary measures the operator can control the kickback and reaction forces. ▶ Always keep your hand well clear of the rotating accessory tool. Kickback could cause the accessory tool to pass across your hand. ▶ Keep your body clear of where the power tool will move if kickback occurs. Kickback will propel the power tool in the direction opposite to the disc’s direction of rotation at the point of snagging. ▶ Exercise special care when working at corners, sharp edges, etc. Avoid allowing the accessory tool to bounce off or jam in the workpiece. The rotating accessory tool has a tendency to jam at corners and sharp edges, or if it bounces off the workpiece. This causes loss of control or kickback. Special safety instructions applicable to grinding: ▶ Use only abrasive disc types approved for use with the power tool and the specific guard designed for the selected disc. Discs for which the power tool was not designed cannot be adequately guarded and are unsafe. ▶ Offset grinding discs must be fitted in such a way that their grinding face does not project past the plane of the guard edge. An incorrectly fitted grinding disc projecting past the plane of the guard edge cannot be adequately shielded. ▶ The guard must be securely attached to the power tool and positioned for maximum safety, so that the smallest possible segment of the abrasive disc is exposed toward the operator. The guard helps protect the operator from flying fragments, accidental contact with the abrasive disc, and flying sparks that could ignite clothing. ▶ Use abrasive discs for the recommended applications only. For example: Never try to use the flat side of an abrasive cut-off disc for grinding. Abrasive cut-off discs are intended for cutting at their peripheral edge. Lateral forces applied to these discs can cause them to shatter. ▶ Always use an undamaged clamping flange of the correct size and shape for your selected grinding disc. The correct flange supports the grinding disc, reducing the risk of disc breakage. Flanges for cut-off discs can differ from those for other grinding discs. Printed: 27.07.2017 | Doc-Nr: PUB / 5238733 / 000 / 0216 English ▶ Do not use worn-down, originally larger-diameter grinding discs from larger power tools. Grinding discs intended for a larger power tool are not suitable for the higher speed of a smaller tool and can break.

2.3 Additional safety instructions

Personal safety ▶ Only use the product if it is in perfect working order. ▶ Never tamper with or modify the tool in any way. ▶ Avoid touching rotating parts – risk of injury! ▶ Wear protective gloves also when changing the accessory tool. Touching the accessory tool presents a risk of injury (cuts or burns). ▶ Before starting work, check the hazard class of the dust that will be produced when working. Use an industrial vacuum cleaner with an officially approved protection class in compliance with the locally applicable dust protection regulations. Dust from materials such as lead-based paint, certain types of wood and concrete/masonry/stone containing quartz, minerals or metal may be harmful to health. ▶ Make sure that the workplace is well ventilated and, where necessary, wear a respirator appropriate for the type of dust generated. Contact with or inhalation of the dust may cause allergic reactions and/or respiratory or other diseases among operators or bystanders. Certain kinds of dust are classified as carcinogenic such as oak and beech dust, especially in conjunction with additives for wood conditioning (chromate, wood preservative). Material containing asbestos may be handled only by specialists. ▶ Take breaks between working and do physical exercises to improve the blood circulation in your fingers. Exposure to vibration during long periods of work can lead to disorders of the blood vessels and nervous system in the fingers, hands and wrists. Electrical safety ▶ Before beginning work, check the working area for concealed electric cables or gas and water pipes. External metal parts of the power tool may give you an electric shock if you damage an electric cable accidentally. Using and handling power tools with care ▶ Do not use cutting discs for grinding. ▶ Tighten the accessory tool and flange securely. If the accessory tool and flange are not tightened securely, the accessory tool may work loose from the spindle due to the braking effect of the motor after switching off. ▶ Comply with the manufacturer's instructions for handling and storing grinding discs. 3 Description
