ENG ENGLISH 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. It is recommended to use a stationary extraction system and to place a ground fault circuit interrupter (GFCI) downstream. When the angle grinder is shut down via the FI circuit breaker, it must be checked and cleaned. See chapter 9 Cleaning for more information on cleaning the motor. 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 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 disconnect the power tool from the mains supply (use nonmetallic 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). Connect a FI circuit-breaker with max. release current (30 mA) upstream when using the machine outdoors! Pull the plug out of the socket before making any 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. Do not switch on the machine if tool parts or guard devices are missing or defective. 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. 5 Overview See page 3 (please unfold). 1 Support flange 2 Spindle 3 Spindle locking button 4 Lock (to prevent the machine from being switched on unintentionally, or for continuous operation)* 5 Trigger ( for switching on and off) 6 Button (to turn the main handle)* 7 Main handle 8 Additional handle / Additional handle with vibration damping * 9 Safety guard 10 Clamping nut * 11 2-hole spanner * 12 Lever (to adjust safety guard without the use of tools) * depending on equipment/not in scope of delivery 6 Commissioning Before plugging in, check to see that the rated mains voltage and mains frequency, as specified on the rating label, match your power supply. 6.1 Attaching the additional handle Always work with the additional handle attached (8)! Manually screw in the additional handle securely in the left, centre or right threaded hole (depending on requirements). 6.2 Attaching the safety guard (for work involving grinding wheels) For reasons of safety, the safety guard (9) should always be attached when roughing work is performed. For reasons of safety, the special parting guard should always be attached before 16
