back caused by a jammed cut-off wheel. Large workpieces tend to sag under their own weight. Workpieces must be supported on both sides of the wheel, near the cut and also along the edge. h) 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. 3.4 Safety Warnings Specific for Wire Brushing Operations: a) Be aware that wire bristles are lost by the brush even during ordinary operation. Do not overstress the wires by applying an excessive load to the brush. The wire bristles can easily penetrate light clothing and/or skin. b) Before using a brush, allow it to run for at least one minute at operating speed. Make sure that no one is positioned in front of or in line with the brush during this time. Loose wire bristles may be released during the running-in time. c) Direct the rotating brush away from you. When working with these brushes, remember that small particles and tiny wire bristles may be ejected at high speed and may penetrate the skin. 3.5 Additional Safety Instructions WARNING - Always wear protective goggles. Use elastic cushioning layers if they have been supplied with the abrasive and if required. Observe the specifications of the tool or accessory manufacturer! Protect the discs from grease or impacts! Abrasives must be stored and handled with care in accordance with the manufacturer's instructions. Never use parting grinder discs for roughing work. Do not apply pressure to the side of parting grinder discs. The workpiece must lay flat and be secured against slipping, e.g. using clamps. Large workpieces must be supported adequately. Keep hands away from the rotating tool! Remove swarf and similar material only when the machine is at a standstill. Prior to use, ensure that the coated abrasive is properly fitted and secured. Run the tool in idling for 60 seconds in a safe position and bring to a standstill immediately if there are significant vibrations or if other deficiencies are determined. If such a situation occurs, check the machine to determine the cause. Ensure that sparks produced during work do not constitute a risk to the user or other personnel and are not able to ignite inflammable substances. Endangered areas must be protected with flameresistant covers. Make sure that fire-risk areas are always provided with suitable fire extinguishers. Dust from material such as paint containing lead, some wood species, minerals and metal may be harmful. Contact with or inhalation of the dust may ENGLISH en cause allergic reactions and/or respiratory diseases to the operator 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 must only be treated by specialists. - Use a dust extraction device where possible. - The work place must be well ventilated. - The use of a dust mask of filter class P2 is recom- mended. Follow national requirements for the materials you want to work with. Materials emitting dusts or vapours that may be harmful to health (e.g. asbestos) must not be processed. When working in dusty conditions, ensure that ventilation openings are not blocked. If it becomes necessary to remove dust, first disconnect the power tool from the mains supply (use non-metallic objects) and avoid damaging internal components. Damaged, eccentric or vibrating tools must not be used. For safety reasons, always ensure the rubber sleeve is fitted while you work (4). Pull the plug out of the plug socket before any adjustments, conversions or servicing are performed. During machining, of metals in particular, conductive dust can form deposits inside the machine. This can lead to the transfer of electrical energy onto the machine housing. This can mean a temporary danger of electric shocks. This is why it is necessary when the machine is running to blow compressed air through the rear ventilation slots of the machine regularly, frequently and thoroughly. The machine must be held firmly in this case. We recommend using a stationary extractor system and connecting a residual current circuit-breaker (FI) upstream. When the machine is shut down via the FI circuit-breaker, it must be checked and cleaned. For information on cleaning the motor, see chapter 7. Cleaning.
