For your safety. Do not use this machine before you have thor- oughly read and completely understood theseop- erating instructions, including the figures, specifications, and safety regulations. Please also observe the relevant national industrial safe- tyregulations (e. g. in Germany: BGV A2, BGR 500). Non-observance of the safety instructions in the said documentation can lead to an electric shock, burns and/or severe injuries. This Instruction Manual should be kept for later use and enclosed with the power tool, should it be passed on or sold. Intended use of the machine. This machine is intended for grinding metal materials (except magnesium) and for grinding with the radius grinding module GRIT GXR or the cylindrical grinding device GRIT GXC using the grinding belts recom- mended by FEIN in weather-protected environments. Special safety instructions. Ensure stable positioning and a level set-up of the sub base. Fasten the sub base to the floor. If the sub base tips over during working, this can cause serious injuries. Use suitable mounting material to mount the machine to the sub base. Faulty assembly can cause the machine to loosen from the sub base during operation and lead to serious accidents. Wear personal protective equipment. Depending on application, use face shield, safety goggles or safety glasses. Where appropriate, wear dust mask, hearing protectors, gloves and workshop apron capable of stop- ping small abrasive or workpiece fragments. The eye protection must be capable of stopping flying debris generated by various operations. The dust mask or res- pirator must be capable of filtrating particles generated by your operation. Prolonged exposure to high inten- sity noise may cause hearing loss. While working, do not wear loose clothing, jewellery or open, long hair. Despite protective devices, loose objects can be snagged or caught by moving parts and lead to injury. Do not use worn, torn or heavily clogged grinding belts. Handle grinding belts carefully and store them accord- ing to the manufacturer’s instructions. Do not bend or fold grinding belts! Damaged grinding belts can tear, be flung away and injure someone. Do not use grinding belts or other accessories which are not specifically designed and recommended by the power tool manufacturer. Safe operation is not ensured merely because a grinding belt or accessory fits your machine. Always use the protective devices attached on the machine. The protective devices must be securely mounted to the machine in order to achieve maximum safety. The protective devices are supposed to protect the user from grinding particles thrown from the machine and from accidental contact with the grinding belt. Warning! Danger of fire and explosion! When grinding metals (e.g., aluminium), dust develops that may be combustible or explosive. Do not operate the machine near flammable materials. Sparks could cause these materials to ignite. Warning! Danger of fire! When grinding metals, glowing metal and sanding-belt particles develop that are col- lected in the chip/grinding-dust box. Before emptying, the contents of the chip/grinding-dust box must have cooled down sufficiently and may only be disposed of in suitable containers. Pay attention that other persons are not put at risk from sparking. Remove flammable materials in close vicinity. Sparking occurs when grinding metal. Keep bystanders a safe distance away from work area. Anyone entering the work area must wear personal pro- tective equipment. Fragments of workpiece or of a bro- ken accessory may fly away and cause injury beyond immediate area of operation. The workpiece must always lie securely on the grinding rest and the stop. Workpieces that are too small or too thin may not be worked. Danger of injury from work- pieces being thrown from the machine. The surface being worked can become very hot. Do not touch it with your hands. Never touch the running grinding belt. Danger of injury. In situations of danger, immediately press the safety pushbutton. The machine runs on for approx. 50 sec- onds. Clean the ventilation openings on the power tool at reg- ular intervals using non-metal tools. The blower of the motor draws dust into the housing. An excessive accu- mulation of metallic dust can cause an electrical hazard. The mains plug of the machine may be mounted only by a qualified electrician. The protective conductor in the mains socket outlet must be connected with the pro- tective earthing of the mains supply. Pull out the mains plug for maintenance and repair! Switching the machine on unintentionally can lead to serious injuries. Have the electrical safety of the machine checked reg- ularly in accordance with statutory regulations. For machines t hat have not been checked, there may be danger of electrical shock! Check the rotation direction of the motor before start- ing the operation of the machine for the first time. If the rotation direction of the motor is incorrect, the work- piece can be thrown from the machine and cause an accident. The rotation direction may be changed only by a qualifiedelectrician. Make sure that you or other persons are not standing directly next to the grinding belt when switching the machine on. The grinding belt can tear apart and cause serious injuries.15

Handling hazardous dusts For work procedures with this power tool where material is removed, dusts develop that can be hazard- ous to one’s health. Contact with or inhaling some dust types, e. g. asbestos and asbestos-containing materials, lead-containing coat- ings, metal, some wood types, minerals, silicate parti- cles from materials containing stone, paint solvents, wood preservatives, antifouling paints for vessels, can trigger allergic reactions to the operator or bystanders and/or lead to respiratory infections, cancer, birth defects or other reproductive harm. The risk from inhaling dusts depends on the exposition. Use dust extraction matched appropriately for the developing dust, as well as personal protective equipment and pro- vide for good ventilation of the workplace. Leave the processing of asbestos-containing materials to special- ists. Wood and light-metal dust, hot mixtures of grinding dust and chemical materials can self-ignite under unfa- vourable conditions or cause an explosion. Avoid sparking in the direction of the dust collector as well as overheating of the power tool and the materials being sanded, empty the dust collector/container in time, observe the material manufacturer’s working instruc- tions, as well as the relevant regulations in your country for the materials being worked.
