User manual BOSCH HSV744020N

[. . . ] cluttered or dark areas invite accidents. B) Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes. C) Keep children and bystanders away while operating a power tool. [. . . ] The tool insert jams when: -- the power tool is subject to overload or -- it becomes wedged in the workpiece. When working with the machine, always hold it firmly with both hands and provide for a secure stance. The power tool is guided more secure with both hands. A workpiece clamped with clamping devices or in a vice is held more secure than by hand. Always wait until the machine has come to a complete stop before placing it down. The tool insert can jam and lead to loss of control over the power tool. 20 | English Products sold in GB only: Your product is fitted with an BS 1363/A approved electric plug with internal fuse (ASTA approved to BS 1362). If the plug is not suitable for your socket outlets, it should be cut off and an appropriate plug fitted in its place by an authorised customer service agent. the replacement plug should have the same fuse rating as the original plug. The severed plug must be disposed of to avoid a possible shock hazard and should never be inserted into a mains socket elsewhere. Products sold in AUS and NZ only: Use a residual current device (RCD) with a rated residual current of 30 mA or less. Before any work on the machine itself, pull the mains plug. Dusts from materials such as lead-containing coatings, some wood types, minerals and metal can be harmful to one's health. Touching or breathing-in the dusts can cause allergic reactions and/or lead to respiratory infections of the user or bystanders. Certain dusts, such as oak or beech dust, are considered as carcinogenic, especially in connection with wood-treatment additives (chromate, wood preservative). Materials containing asbestos may only be worked by specialists. As far as possible , use a dust extraction system suitable for the material. ­ Provide for good ventilation of the working place. Use the dust/chip extraction only when working concrete, brick and brickwork. Wood or plastic chips can easily lead to clogging. Do not work metallic materials with the extraction device mounted. Hot metal chips can ignite parts of the extraction device. [. . . ] 26 | English Adjusting the Speed/Impact Frequency The speed/impact rate of the switched on power tool can be variably adjusted, depending on how far the On/Off switch 8 is pressed. Light pressure on the On/Off switch 8 results in low speed/impact rate. further pressure on the switch increases the speed/impact rate. Preselecting the Speed/Impact Frequency (PSB 650 RE/PSB 6500 RE/PSB 650 RA) With the thumbwheel for speed preselection 14, the required speed/impact frequency can be preselected even during operation.
