en ENGLISH recommendations when selecting sanding paper. Larger sanding paper extending beyond the sanding pad presents a laceration hazard and may cause snagging, tearing of the disc or kickback. 3.6 Safety Warnings Specific for Wire Brushing Operations: a) Be aware that wire bristles are thrown by the brush even during ordinary operation. Do not overstress the wires by applying excessive load to the brush. The wire bristles can easily penetrate light clothing and/or skin. b) If the use of a guard is recommended for wire brushing, do not allow any interference of the wire wheel or brush with the guard. Wire wheel or brush may expand in diameter due to work load and centrifugal forces. 3.7 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! Grinding wheels 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 sufficiently supported. If accessories with threaded inserts are used, the end of the spindle may not touch the base of the hole on the grinding tool. Make sure that the thread in the accessory is long enough to accommodate the full length of the spindle. The thread in the accessory must match the thread on the spindle. See page 3and chapter 13. Technical Specifications for more information on the spindle length and thread. 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. Here, the machine must be held firmly. We recommend using a stationary extractor system and connecting a residual current circuit-breaker (FI) upstream. When the angle grinder is shut down via the FI circuit-breaker, it must be checked and cleaned. See chapter 8. Cleaning for more information on cleaning the motor. When working in dusty conditions, ensure that 8 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. Avoid damage to gas or water pipes, electrical cables and loadbearing walls (static). Pull the plug out of the socket before any making adjustments, converting or servicing the machine. A damaged or cracked additional handle must be replaced. Never operate a machine with a defective additional handle. A damaged or cracked safety guard must be replaced. Never operate a machine with a defective safety guard. This power tool is not suitable for polishing work. Improper use of the machine will void the warranty! The motor may overheat and damage the electric power tool. We recommend using our angle polisher for polishing work. Secure small workpieces. For example, clamp in a vice. Reduce dust exposure: Particles generated when working with this machine may contain substances that can cause cancer, allergic reactions, respiratory diseases, birth defects or other propagation defects. Some of these substances include: Lead (in paint containing lead), mineral dust (from bricks, concrete etc.), additives used for wood treatment (chromate, wood preservatives), some wood types (such as oak or beech dust), metals, asbestos. The risk depends on for how long the user or nearby persons are exposed to the substance. This dust must not be allowed to enter your body. Do the following to reduce exposure to these substances: Ensure good ventilation of the workplace and wear appropriate protective equipment, such as respirators able to filter microscopically small particles. Observe the relevant guidelines for your material, staff, application and place of application (e.g. occupational health and safety regulations, disposal). Collect the generated particles at the source, avoid deposits in the surrounding area. Use suitable accessories for special work (see chapter 10.), thus less particles enter the environment in an uncontrolled manner. Use a suitable extraction unit. Reduce dust exposure with the following measures: - Do not direct the escaping particles and the exhaust air stream at yourself or nearby persons or on dust deposits. - Use an extraction unit and/or air purifiers - Ensure good ventilation of the workplace and keep clean using a vacuum cleaner Sweeping or blowing stirs up dust - Vacuum or wash the protective clothing Do not blow, beat or brush
