en ENGLISH kickback. Large workpieces tend to sag under their own weight. Supports must be placed under the workpiece near the line of cut and near the edge of the workpiece on both sides of the wheel. f) 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. 4.5 Safety Warnings Specific for Sanding Operations: a) Do not use excessively oversized sanding disc paper. Follow manufacturer's 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. 4.6 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. 4.7 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 discs 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 2 and chapter 14. Technical Specifications for more information on the spindle length and thread. Use of a fixed extractor system is recommended. Dust from material such as paint containing lead, some wood species, minerals and metal may be 14 harmful. Contact with or inhalation of the dust may 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. - Where the use of a dust extraction device is possible it shall be used. - The work place must be well ventilated. - The use of a dust mask of filter class P2 is recommended. Follow national requirements for the materials you want to work with. Materials that generate 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 remove the battery pack (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 load-bearing walls (static). Remove the battery pack from the machine before any adjustments, conversions or servicing are performed. Before fitting the battery pack, make sure that the machine is switched off. 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. 4.8 Safety instructions for battery packs: Protect battery packs from water and moisture! Do not expose battery packs to naked flame! Do not use faulty or deformed battery packs! Do not open battery packs! Do not touch or short-circuit battery packs! Slightly acidic, flammable fluid may leak from defective Li-ion battery packs! If battery fluid leaks out and comes into contact with your skin, rinse immediately with plenty of water. If battery fluid leaks out and comes into contact with your eyes, wash them with clean water and seek medical attention immediately. 5.
