The term “power tool” used in the safety instructions refers to mains-powered electrical tools (with a mains cable) and battery-powered electrical tools (without a mains cable).

Workplace safety

• Keep work area clean and well lit. Disorganised and unlit work areas can result in 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 may cause you to lose control of the device.

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 use the cable for another purpose, for example, carrying or hanging the power tool or pulling the plug out of t he socket . Keep t he cable away from heat , oil, sharp edges or moving device par ts. Damaged or coiled cables increase the risk of an electric shock.
• If you work with an electric tool outdoors, only use extension cables that are also permitted for outdoor use. Using an extension cable suitable for outdoor use reduces the risk of an electric shock.
• If you cannot avoid using the electrical tool in a wet environment , use a fault- current circuit breaker. Use of an RCD reduces the risk of electric shock.

Personal safety

• Always remain attentive, pay attention to what you are doing and be sensible when working with electric tools. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of carelessness when using electrical tools can result in serious injuries.
• Use personal protective equipment. Always wear eye protection. Wearing personal protective equipment, such as dust masks, anti-slip safety shoes, safety helmet or hearing protection, depending on the type and use of the electric tool, reduces the risk of injuries.
• Prevent unintentional starting. Make sure the switch is in the off- position before connecting t o t he power supply, picking up or carrying t he electric tool. Keeping your finger on the switch when carrying the electric tool or having the device already switched on when connecting it to the power supply may result in accidents.
• Remove any adjusting key or wrench before turning the power tool on. A tool or spanner that is located in a rotating device part may result in injuries.
• 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 hair, clothing and gloves away from moving par ts. Loose clothes, jewellery or long hair can be caught in moving parts.
• If dust extraction and collection devices can be mounted, make sure that they are connected and used properly. Use of dust collection can reduce dust-related hazards.
• Do not allow yourself to be lulled into a false sense of security and do not ignore the safety rules for electric tools, even when you have used it many times and have become familiar with it. A careless action can cause severe injury within a fraction of a second.

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.
• Remove the plug from the socket before setting the device, changing accessories or putting the device away. 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 let people use the device who are not familiar with it or who have not read these instructions. Power tools are dangerous in the hands of untrained users.
• Maintain the electric tool with care. Check whether moving parts function properly and do not get stuck and whether par ts are broken or are damaged and thus adversely affect the electric tool function. Have damaged par ts repaired before using the device. 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 per formed. Use of the power tool for operations different from those intended could result in a hazardous situation.
• Keep the gripping surfaces dry, clean and free of oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.

Service

• Have your power tool ser viced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.

Safety instructions for all applications

Common safety instructions for grinding and sandpaper grinding:

• This electric tool is to be used as a grinder and sandpaper grinder. Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to observe the following instructions may result in electric shock, fire and / or serious injury.
• This electric tool is not suitable for working with wire brushes, polishing, and cut-off grinding. Operations for which the power tool was not designed may create a hazard and cause personal injury.
• Do not use accessories that 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 that rotate faster than permitted can break and fly off at high speed.
• The outside diameter and the thickness of your accessory must be within the capacity rating of your power tool. Incorrectly sized accessories cannot be adequately guarded or controlled.
• Insert tools with threaded inserts must fit exactly on the thread of the grinding spindle. For insert tools that are mounted by means of a flange, the hole diameter of the insert tool must match the mounting diameter of the flange. Insert tools that are not precisely attached to the electric tool rotate unevenly, vibrate very strongly and can cause a loss of control.
• Do not use a damaged accessory. Before each use, check insert tools such as grinding discs for chipping and cracks, grinding wheels for cracks, wear or heavy wear. If a power tool or accessory is dropped, inspect for damage or install an undamaged accessory. Once you have checked and used the insert tool, ensure that you and all other persons in the vicinity remain outside the plane of the rotating insert tool and allow the device to run for one minute at the maximum speed. Damaged insert tools usually break during the test period.
• Wear personal protective equipment. Depending on the application, use a face shield, safety goggles or safety glasses. Where appropriate, wear a dust mask, hearing protection, protective gloves or a special apron that will keep small grinding and material particles away from you. The eye protection must be capable of stopping flying debris generated by various operations. Dust or breathing masks must filter the dust generated during use. Prolonged exposure to high-intensity noise may cause hearing loss.
• 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 broken insert tools can fly away and cause injuries even outside the direct working range.
• When performing work during which the insert tool can meet with concealed power lines or its mains cable, only hold the electric tool by the insulated gripping surfaces. Contact with a live power line can also electrify metal device parts and lead to an electric shock.
• Position the cord clear of the spinning accessory. If you lose control of the device, the main cable can be severed or caught and your hand or arm pulled into the rotating insert tool.
• 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, 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 accumulation of powdered metal may cause electrical hazards.
• Do not operate t he 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.

Kick-back and corresponding safety instructions

Kick-back is the sudden reaction resulting from a caught or jammed rotating insert tool, such as a grinding disc, grinding wheel, wire brush, etc. Catching or jamming results in the rotating insert tool stopping abruptly. As a result, an uncontrolled electric tool is accelerated against the direction of rotation of the tool attachment at the blocking point.For example, if a grinding disc catches or jams in the workpiece, the edge of the grinding disc that plunges into the workpiece can get caught, causing the grinding disc to break away or kick back. The wheel may either jump toward or away from the operator, depending on the direction of the wheel’s movement at the point of pinching. Abrasive wheels may also break under these conditions. Kickback is the result of incorrect or deficient use of the electrical tool. It can be prevented by suitable precautionary measures, as described in the following.

1. Maintain a firm grip on the power tool and position your body and arm to allow you to resist kickback forces. Always use an auxiliary handle, if provided, for maximum control over kickback or torque reaction during start-up. The operator can control torque reactions or kickback forces if proper precautions are taken.
2. Never place your hand near the rotating accessory. The accessory may kick back over your hand.
3. Do not position your body in the area where the power tool will move if kickback occurs. Kickback will propel the tool in a direction opposite to the wheel’s movement at the point of snagging.
4. Use special care when working corners, sharp edges etc. Avoid bouncing and snagging the accessory. The rotating tool attachment tends to jam at corners, sharp edges or when it bounces back. This causes a loss of control or kickback.
5. Do not attach a saw chain woodcarving blade or toothed saw blade. Such blades create frequent kickback and loss of control.

Special safety instructions for grinding:

1. Only use the grinding bodies approved for your electric tool and the protective cover provided for these grinding bodies. Grinding bodies that are not intended for the electric tool cannot be adequately shielded and are unsafe.
2. Cranked grinding discs must be mounted so that their grinding surface does not protrude above the plane of the protective cover edge. An improperly mounted grinding disc that protrudes above the level of the protective cover edge cannot be adequately shielded.
3. The protective cover must be securely attached to the electric tool and, for maximum safety, adjusted so that the smallest possible part of the grinding body is open and facing the operator. The protective cover helps to protect the operator from fragments, accidental contact with the grinding body and sparks that could ignite clothing.
4. Grinding bodies may only be used for the recommended applications.For example: Never grind on the side surfaces of a cutting wheel. Cutting wheels are designed to remove material with the edge of the disc. Lateral forces on this grinding body can break it.
5. Always use undamaged clamping flanges of the correct size and shape for the grinding disc selected by you. Suitable flanges support the grinding disc and reduce the danger of the grinding disc breaking. Flanges for cut ting wheels may differ from flanges for other grinding discs.
6. Do not use worn grinding discs from large electric tools. Grinding discs for larger electric tools are not designed for the higher speeds of smaller electric tools and can break.

Additional safety instructions for sandpaper grinding

1. Do not use excessively oversized sanding disc paper. Follow manufacturer’s recommendations, when selecting sanding paper. Sanding sheets that protrude beyond the grinding wheel can cause injuries as well as jamming, tearing of the sanding sheets or kick-back.

Additional safety instructions

• Use the appropriate detection devices in order to detect hidden supply lines or consult the local utility company. Contact with electrical lines can result in fire and electric shock. Damage to a gas line can lead to an explosion. Penetrating a water pipe causes property damage or may cause an electric shock.
• Unlock the on/off switch and move it to the off position if the power supply is interrupted, e.g. by a power failure or unplugging the mains plug. This prevents an uncontrolled restart.
• Only use the electric tool for dr y grinding. Water entering a power tool will increase the risk of electric shock.
• Only run the electric tool against the workpiece when it is switched on and only switch it off after you have lifted it off the workpiece. The electric tool may move suddenly.
• Make sure that no persons are endangered by flying sparks. Remove combustible materials from the vicinity. When grinding metals, flying sparks occur.
• Do not use worn, torn or heavily clogged grinding tools. Damaged grinding tools can tear, be thrown away and injure someone.
• Do not use cutting or grinding discs or cup brushes. The electric tool is not suitable for use with these insert tools. There is a danger of injury!
• Always use the supplied suction hose and a suitable dust extraction unit when operating the electric tool. Using a dust extraction unit can reduce hazards caused by dust.
• Attention: Risk of fire! Avoid overheating the grinding material and the grinder. Always empty the dust tank before work breaks. Grinding dust in the dust bag, microfilter, paper bag (or in the filter bag or filter of the vacuum cleaner) can self-ignite under unfavorable conditions, such as flying sparks when grinding metals. There is a particular danger if the grinding dust is mixed with paint, polyurethane residues or other chemical substances and the sanding material is hot after working for a long time.
• Hold the electrical tool firmly with both hands and ensure firm footing. It is safer to guide the electrical tool with two hands.
• Wear hearing protection, safety goggles, dust mask and gloves if necessary. Use at least a particle filtering half mask of class FFP 2 as a dust mask.
• Use a dust extraction unit when machining stone. The vacuum cleaner must be permitted to extract stone dust. The use of these devices reduces dust hazards.
• Do not touch insert tools until they have cooled down. The insert tools become very hot when working.
• Wear protective gloves when changing the insert tools. Insert tools become warm during prolonged use.
• Do not machine materials that release hazardous substances, e.g. beech wood or oak wood dust, rock dust or asbestos. These substances are considered carcinogenic.
• Inform yourself about the valid regulations/laws regarding the handling of dusts hazardous to health in your country.
• Never touch the grinding tool when it is running. There is a danger of injury.
• If necessary, use scaffolding to work on. When working on a ladder, it is not possible for you to have a firm footing.
  Warning! This power tool generates an electromagnetic field during operation.This field can impair active or passive medical implants under certain conditions. In order to prevent the risk of serious or deadly injuries, we recommend that persons with medical implants consult with their physician and the manufacturer of the medical implant prior to operating the power tool.

Only perfect grinding tools provide good grinding performance and protect the device.

Grinding

• Hold the device firmly with both hands and ensure firm footing. It is safer to guide the device with two hands.
• Connect your extraction system (own or third-party extraction).
• With third-party extraction: If possible, work with the remote switch- off or automatic start /stop function of the vacuum cleaner. The vacuum cleaner switches on automatically and switches off again with a time delay to remove residual dust from the vacuum hose.
• Switch the device on. Place it with the entire grinding surface on the surface to be machined. Move it over the workpiece with moderate pressure.
• Ensure even contact pressure to increase the service life of the insert tools.
• Excessively increasing the contact pressure does not lead to a higher removal rate, but to greater wear of the device and the insert tool.
• Lift the device from the surface.
• For in-house extraction: Let the electric tool run for a few more seconds to remove any remaining dust from the suction hose (19).

Grinding close to the edge (Fig. 5, 6)
A cover segment (6) of the protection and extraction bonnet (4) can be removed for grinding close to the edge. This allows the inser t tool to reach closer to floor, wall and ceiling edges as well as existing installations such as pipes. The adjacent surfaces can thus be precisely machined.
Expect dust to be generated during this work, as the protective and extraction cover (4) is no longer closed.

• Pull the cover segment (6) forwards out of the protection and extraction cover (4).
• Machine the areas near the edges.
• Put the cover segment (6) back on the extraction cover (4) until it clicks into place.
