GENERAL SAFETY CONDITIONS

NOTE! Get acquainted with all the instructions below. Failure to observe them may lead to an electric shock, fi re or injuries. The notion of electric tool used in the instructions applies to all the tools which are powered with electric current, both wire tools and wireless ones.

OBSERVE THE FOLLOWING INSTRUCTIONS

Place of work The place of work must be properly illuminated and clean. Disorder and poor illumination may be a cause of accidents. Do not work with electric tools in explosive environments, or those which contain infl ammable liquids, gases or vapours. Electric tools generate sparks, which may cause a fi re in case of contact with infl ammable gases or vapours. Do not allow children and outsiders to the place of work. A lack of concentration may result in a loss of control over the tool. Electric safety The plug of the power supply cable must fi t the mains socket. Do not modify the plug. Do not use any adapters whatsoever in order to adapt the plug to the socket. Unmodifi ed plug which fi ts the socket reduces the risk of an electric shock. Avoid contact with grounded surfaces, such as pipes, heaters and refrigerators. Grounding of the body increases the risk of an electric shock.14

ORIGINAL INSTRUCTIONS Do not expose electric tools to precipitation or humidity. Water and humidity which gets into the electric tool increases the risk of an electric shock. Do not overload the power supply cable. Do not use the power supply cable in order to carry the tool or to connect and disconnect the plug from the mains socket. Avoid contact of the power supply cable with heat, oils, sharp tools and moving elements. Damage to the power supply cable increases the risk of an electric shock. In case work is realised outside closed areas, it is necessary to use extension cords designed for applications outside closed areas. Using a correct extension cord permits to reduce the risk of an electric shock. If operating a power tool in a damp location is unavoidable, use a residual current device (RDC) protected supply. Use of an RCD reduces the risk of electric shock. Personal safety Commence work in good physical and psychological conditions. Pay attention to what you do. Do not work if you are tired or under eff ects of medicines or alcohol. Even a moment’s inattention during work may lead to serious injuries. Always use individual means of protection. Always wear goggles. Using individual means of protection, such as dust-masks, protective shoes, helmets and hearing protections permits to reduce the risk of serious injuries. Avoid accidental activation of the tool. Make sure the switch is in the OFF position, before you connect the tool to the mains. Holding the tool with a fi nger on the switch or connecting an electric tool when the switch is in the ON position may lead to serious injuries. Before you turn an electric tool on remove all the spanners and other tools, which have been used for adjustments. A spanner left on rotating elements of the tool may lead to serious injuries. Keep your balance. Maintain an appropriate position. It will permit to control the electric tool in case of unpredicted situations during its operation. Use protective clothes. Do not wear loose clothes or jewellery. Keep your hair, clothes and gloves away from moving elements of the electric tool. Loose clothes, jewellery or long hair may get caught on moving elements of the tool. Use dust extractors or dust containers, if the tool is equipped with any. Make sure they are properly connected. Using of dust extractors permits to reduce the risk of serious injuries. Operation of the electric tool Do not overload the electric tool. Use a proper tool for the given purpose. A correct selection of the tool for the given work will result in a more effi cient and safer work. Do not use the electric tool if the switch is not functioning properly. A tool which may not be controlled by means of a switch is dangerous and must be repaired. Disconnect the plug from the mains socket before any adjustment, replacement of accessories or storage of the tool. It will permit to avoid accidental activation of the electric tool. Store the tool away from children. Do not allow untrained persons to operate the tool. An electric tool may be dangerous in hands of an untrained person. Make sure the tool is properly maintained. Check the tool in order to detects any unfi tting or loose moving elements. Check whether the elements of the tool are not damaged. In case any damaged elements of the tool are detected, they must be repaired before the electric tool is operated. Many accidents are caused by improper maintenance of tools. Cutting tools must be sharp and clean. Properly maintained cutting tools are easier to control during work. Use electric tools and accessories in accordance with the aforementioned instructions. Use the tool in accordance with its purpose, taking into account the kind and conditions of work. Should the tool be used for other applications than the ones it has been designed for, the risk of a dangerous situation increases. Repairs The tool may be repaired only by authorised service centres, which must use solely original spare parts. It will guarantee a proper level of safety of operation of the electric tool.

ADDITIONAL SAFETY INSTRUCTIONS

The tool has been designed exclusively for grinding, grinding with abrasive paper, grinding with wire brushes and cutting. Get acquainted with all the warnings, instructions, illustrations and specifi cations supplied along with the electric tool. If the instructions below are not observed, there is a risk of electric shock, fi re and / or serious injuries. It is prohibited to use the tool as a polishing machine or in a way which does not comply with the manual. Using the tool for jobs it is not designed for implies a risk and may cause injuries. Do not use accessories which have not been designed and are not recommended by the manufacturer. The fact that accessories may be installed in the tool does not mean work with them is safe. The maximum rotational speed of the accessories must be higher than or equal to the maximum rotational speed of the tool. Accessories of a lower rotational speed than the speed of the tool may break during work. The outer diameter and the thickness of accessories must fall within the range of dimensions indicated for the tool. Accessories of incorrect dimensions cannot be properly protected and operated.15 ORIGINAL INSTRUCTIONS

Threaded mounting of accessories must match the grinder spindle thread. The dimensions of the hole in which wheels, disks, fl anges and other accessories are installed must comply with the dimensions of the spindle of the tool. Accessories in which the dimensions of the fi xing hole do not comply with the dimensions of the spindle of the tool, will vibrate after start, which may preclude a proper control of the tool. Do not use damaged accessories. Before each use, make sure the accessories are not splintered, broken or excessively worn. If accessories are dropped make sure they are not damaged or install new accessories. Once accessories have been inspected and installed, all persons must remain away from the plane of rotation of the accessories, and start the tool for a minute with the maximum rotational speed. During the test damaged accessories will be destroyed. Use individual protection means. Depending on the job, wear face protections or safety goggles. If it is required use dust masks, hearing protectors, gloves and aprons protecting from small fragments of the accessories or materials generated during work. Eye protection must stop fl ying pieces generated during work. The dust mask must fi lter dust generated during work. Excessive exposition to noise may lead to hearing impairment. While realising tasks during which the disc may come into contact with a hidden live electric wire or a power supply cable hold the grinder by insulated handles. If the disc touches a live wire, the metal elements of the tool may cause electric shock to the operator of the tool. Maintain a safe distance between the place of work and third persons. Persons who approach the place of work must use individual protection means. Chips generated during work or fragments of damaged accessories may be ejected beyond the direct vicinity of the place of work. Place the power supply cord away from the rotating wheels. In case the operator loses the control over the tool, the cord may be cut or caught, and the hand or arm of the operator may be drawn into the rotating elements of the machine. Never put down the tool until the rotating elements have stopped completely. The rotating elements may „catch” the ground and impede the control of the tool. Do not start the tool while carrying it. Accidental contact with the rotating elements may cause drawing clothes and contact of the tool with the body of the operator. Clean the ventilating holes of the tool regularly. The ventilator of the motor pulls the dust generated during work into the tool. Excessive accumulation of metal particles contained in the dust increase the risk of electric shock. Do not operate the tool in the vicinity of infl ammable materials. The sparks generated during work may cause a fi re. Do not use accessories which require cooling with liquids. Water or cooling liquid may cause an electric shock. Size of thread of accessories must match the grinder’s spindle thread. In case of accessories mounted by means of fl anges, the mounting hole of accessories must match the size of mounting fl ange. Accessories that do not match the fi tting of a power tool will cause imbalance, excessive vibrations and may result in loss of control. Warnings related to the possibility of the tool rebounding towards the operator Rebounding of the tool towards the operator is caused by a sudden reaction to blocked or seized discs or polishing belts or another accessory, which causes a sudden stop of the rotating accessory and a turn of the electric tool opposite to the direction of rotation. For example, if the grinding disc is seized by the object being processed, the edge of the disc, which is at the point of seizure may get deeper into the surface of the material, and thus get ejected. The disc may also move towards or away from the operator, depending on the direction of movement of the grinding wheel at the place of seizure. Grinding wheels may also break. Rebounding of the tool towards the operator is caused by incorrect operation and / or inobservance of the indications contained in the operating manual. It may be prevented if the following recommendations are followed. Hold the tool fi rmly and adopt an adequate position of the body and the hands, which will permit you resist the force generated when the tool rebounds. Always use the additional handle, if it has been supplied with the tool, which will ensure a maximum control when the tool rebounds or turns inadvertently during start. The operator is able to control the turning or rebound of the tool, if adequate safety measures have been taken. Do not ever place hands close to the rotating elements of the tool. The rotating elements may, in case the machine rebounds, get into contact with the hand. Do not remain within the area into which the tool will move in case of rebound. A rebound will propel the tool in the direction opposite to the rotation of the grinding disk, where it is seized. Be particularly careful during work close to corners, sharp edges, etc. Avoid fl icking up and seizure of the grinding disk. During work on corners or edges there is an increased risk of seizure of the grinding disk, which may imply a loss of control over the tool or rebound of the tool. Do not use disks with cutting chains or disk saws. The edges cause frequent rebounds, which may lead to a loss of control over the tool. Warnings related to grinding and cutting with abrasive disks Use only disks which are adequate for the tool and guards designed for the given type of disk. Disks which are not compatible with the tool cannot be properly protected and are not safe. The convex disc must be mounted in such a way that its grinding surface must not protrude beyond the plane of cover protective collar. Incorrectly mounted disc that protrudes above the cover poses a threat to safety during operation.16

ORIGINAL INSTRUCTIONS The grinding surface of centre depressed wheels must be mounted below the plane of the guard lip. An improperly mounted wheel that projects through the plane of the guard lip cannot be adequately protected. The guard must be secured to the tool and placed in a position which ensures maximum safety, so that the smallest possible area of the disk is unprotected towards the operator. The guard helps to protect the operator from broken fragments of the disk and prevents accidental contact with the disk. The disk must be used as intended. For example: do not grind with disks designed for cutting. Abrasive disks for cutting are designed for circumferential load, and the lateral forces applied to such a disk may destroy it. Always use undamaged fi xing disks, whose dimensions must be compatible with the grinding disk. Adequate fi xing disks for the abrasive disk reduce the risk of damaging the grinding disk. The fi xing disks for cutting disks may diff er from the fi xing disks designed for grinding disks. Do not use worn abrasive disks from bigger tools. An abrasive disk of a bigger diameter is not adapted to a bigger rotational speed of smaller tools and may break. Warnings related to grinding with abrasive paper Do not use discs with abrasive papers of an excessive size. While selecting the grinding wheel, follow the guidelines of the manufacturer. Abrasive paper which signifi cantly exceeds the size of the disc may cause injuries and increases the risk of seizure, tearing or rebounding towards the operator. Warnings related to work with wire brushes Be careful, since fragments of wires are ejected from the brush also during normal work. Do not overload the wires exerting excessive force on the brush. The wires may easily perforate light clothes and/or the skin. If it is recommended to use guards while working with wire brushes, preclude any contact of the brush with the guard. The diameter of the wire brush may increase due to the load and the centrifugal force.

INSTALLATION OF THE EQUIPMENT

Install the grinding disk guard Place the disc guard on the cylindrical section of the body around the spindle and using screws or a clamping ring fi x it so that the guard is straight and safe. Position the grinding disk guard so that the unprotected area of the disk is as far as possible from the hand which holds the handle. Do not ever work with the grinder without a properly installed disk guard! The grinder is provided along with a protection which guarantees proper protection only while grinding with abrasive discs and discs with abrasive paper as well as certain wire brushes. Once installed on the spindle, the disc must not protrude beyond the edge of the protection. In case of any other permitted task, contact the manufacturer in order to purchase a guard for such kind of work. Installation of the additional handle If required install the handle screwing it securely to the head of the tool.

USING ABRASIVE DISKS

ATTENTION! Installation of the abrasive disks must be realised with the power supply off . Remove the plug of the cord of the grinder from the socket Installation of abrasive disks Disconnect the tool. Remove the plug from the socket! During installation make sure the edges A (IV) at the bottom spindle mandrel and the fi xing disks align precisely. Place the upper fi xing disk on the spindle. Place the abrasive disk on the spindle and the installed fi xing disk. Screw the lower fi xing disk onto the spindle. Press the spindle blockade and tighten the lower fastening disk with a spanner and release the blockade. Insert the plug of the power supply cord of the tool into the socket, turn the grinder on and observe its operation without any load for approximately one minute. Remove the plug from the socket and make sure the disk is installed securely. Position of the fi xing disks Please note that the discs may have diff erent thickness in the area in which they are installed on the spindle. Depending on the abrasive disks used - thin ones whose thickness does not exceed 3.2 mm or thick ones whose thickness exceeds 3.2 mm) the position of the fi xing disk diff ers (III). Do not use the discs thicker than 6 mm. Removal of the abrasive disks Turn the grinder off and remove the plug of the electric cord of the grinder from the mains socket.17 ORIGINAL INSTRUCTIONS

Press the spindle blockade and unscrew the lower fi xing disk using a spanner, and remove the abrasive disk from the spindle. Clean the spindle and the fi xing discs removing dust and other contamination generated during work. Kinds of abrasive discs For work with the grinder it is possible to use any grinding disc for angular grinders whose acceptable tangential velocity is at least 80 m/s and whose fi xing and external diameters are those indicated in the technical data table. If the abrasive disc has an unthreaded fi xing hole, then it is required to use a fi xing disc. It is also possible to use discs whose external diameter complies with the values indicated in the technical data table with an M14 threaded hole. In such cases it is required to use fi xing discs, and the disc must be fi xed directly to the spindle, locking it with the button, and tightening the disc securely with a fl at wrench (which is not provided with the grinder). In case of discs which permit installation of abrasive paper circles with a Velcro fastener, it is only permitted to use abrasive paper circles whose diameter complies with the value indicated in the technical data table. The circles must be placed on the disc concentrically. The edge of the circle must not be behind the edge of the disc. It is also possible to use diamond abrasive discs of dimensions complying with the values indicated in the technical data table, designed for dry cutting and grinding. Installation must be carried out in the same manner as in the case of abrasive discs. In case of work with metals, it is recommended to use grinding wheels made of materials designed for processing of the given metal. Get acquainted with the documentation provided with the abrasive disc. For processing of ceramic materials you may use grinding wheels designed for stone or diamond discs for dry tasks. Wire brushes and discs with abrasive paper should be used to remove old paint from metal elements. It is prohibited to modify the fi xing hole, the spindle or using adapter rings in order to adapt the diameter of the fi xing hole to the diameter of the spindle. It is prohibited to use abrasive discs whose fi xing diameter diff ers from the value indicated in the technical data table. It is prohibited to use discs with cutting chain or circular saws, since they increase the risk of rebounding towards the operator. Attention! It is prohibited to use other discs than those permitted in this manual, even if they can be installed on the spindle of the grinder. Inappropriate discs may not resist the load generated during work with the angular grinder. Damaged and breaking grinding discs imply a danger of serious injuries or death.

OPERATION OF THE GRINDER

Remove the plug from the socket! Before work with the tool make sure the body of the tool and the connection cable are not damaged. If any damage is detected, it is prohibited to connect the grinder to the mains! Install the grinding disk guard and the handle. Do not ever operate the grinder if the grinding disk guard is not installed! Select an adequate grinding disk and install the disk on the spindle of the grinder.

The processed material must be appropriately fi xed so that it does not move during processing, for example using an anvil or clamps. The disc of the grinder rotates with a high velocity and improper fi xing of the material to be processed may cause its movements during work, which implies an increased risk of serious injuries. In case of cutting the material being cut must be supported at both sides of the cutting line, although in a manner that during cutting does not cause seizure of the cutting disc. The supports must be placed close to the edge of the material being cut and close to the cutting line. Wear protective goggles, hearing protectors and protective gloves. Make sure the switch is off and insert the plug of the power supply cord of the grinder into the socket. Adapt a correct position which ensures equilibrium and start the grinder with the switch. If the switch is in the upper section or on the lateral part of the body of the grinder, then in order to turn it on it is required to press the switch at its rear part, and without releasing it, move it forward towards the symbol „I”. The switch is equipped with a catch that permits to lock it in this position, which facilitates long operation. In order to turn the grinder off , press the switch at its rear part and let it retract. If the grinder is equipped with a switch located in the lower part of the handle, then press it and hold the lock button, and afterwards press the switch. A pressed switch must be held during work, but it is not necessary to hold the lock button. Releasing the sw itch will turn the grinder off . Such switch cannot be locked during work. Proceed to work applying the correct surface of the disk to the material: - in case of abrasive discs for grinding, it is required to grind with the lateral surface and/or the front surface, - in case of grinding with fl ap discs, it is required to grind with the lateral surface so that the abrasive paper move parallel to the material being processed, - in case of discs with Velcro fasteners to fasten abrasive paper, grinding must be realised with the lateral surface, - in case of wire brushes grinding must be realised with the tips of the wires and not their lateral surfaces, - in case of cutting disc sit is required to cut with the front surface, do not polish with the front surface of cutting discs. While grinding with the lateral surface, it is required to maintain the grinder at an angle which does not exceed 30° to the18

ORIGINAL INSTRUCTIONS processed surface (V). Move the grinder with smooth movements towards you and away from you. During cutting the cutting disc should be at the straight angle to the surface being cut. Do not cut at any other angle. It is prohibited to change the angle of the cutting disc to the processed material during cutting. Cutting must be realised along a straight line. Otherwise the risk of the disc being seized in the material increases, which may cause rebounding of the tool towards the operator, or the disc may break. During cutting the grinder must be moved in the same direction as the rotation of the disc (VI). During work with the grinder do not exert excessive pressure against the material and do not make violent movements, so as to avoid seizure or breaking of the grinding disk. Do not overload the grinder – the temperature of the external surfaces must not exceed 60°C. once the work has fi nished, unplug the grinder and inspect it. Attention! The disc may rotate for some time once the grinder has been turned off . Before any inspection wait until the disc has cooled down. During work both the disc and the processed material may heat up to a high temperature. Remember! While operating the angular grinder: Always wear protective goggles. Do not use grinding wheels whose maximum acceptable tangential velocity is lower than 80 m/s! Do not use grinding wheels whose maximum acceptable rotational speed is lower than the rotational speed of the grinder. The declared total value of vibrations was measured with a standard method and may be used to compare diff erent tools. The declared total value of vibrations may be used at the preliminary evaluation of exposition. Attention! Emission of vibrations during work with the tool may diff er from the declared value, depending on how the tool is used. Attention! It is required to determine the safety measures to protect the operator, which are based upon evaluation of exposition under real conditions of operation (including all the stages of the working cycle, e.g. when the tool is off or idling, as well as when the tool is on).

MAINTENANCE AND OVERHAUL

ATTENTION! Before any adjustment, technical service or maintenance operations unplug the tool. Once the operations have been fi nished, the technical conditions of the tool must be assessed by means of external evaluation and inspection of the following elements: body and handle, conductor with a plug and defl ection, functioning of the electric switch, patency of ventilation slots, sparking of brushes, noise level of functioning of bearings and gears, start-up and smoothness of operation. During the guarantee period, the user cannot dismantle the electric tools or change any sub-assemblies or elements, since it will cancel any guarantee rights. All irregularities detected at overhaul or during functioning of the tools are a signal to have the tool repaired at a service shop. Once the functioning has been concluded, the casing, ventilation slots, switches, additional handle and protections must be cleansed with a stream of air (at a pressure not exceeding 0.3 MPa), with a brush or a cloth without any chemical substances or cleaning liquids. Tools and handles must be cleansed with a clean cloth.19 ORIGINALANLEITUNG
