[. . . ] If the mains cable is damaged or cut through while working, do not touch the cable but immediately pull the mains plug. S Do not drill, fasten or cut into blind areas where electric, gas or water lines may exist. Use appropriate detectors to determine if these lines are hidden in the work area or call the local utility company for assistance. Breaking into a water pipe will cause property damage or may cause an electric shock. [. . . ] Insert the saw blade 1 between the stroke rod 9 and the clamping plate 8. Take care that the securing pin of the stroke rod 9 engages in the hole of the saw blade (Saw blade cannot be pulled out). Before putting into operation, check the saw blade for secure seating. Check for correct mains voltage: The voltage of the power source must agree with the voltage specified on the nameplate of the machine. Light application of pressure on on/off switch 6 results in low stroke rate. A selection of the illustrated or described accessories can be found at the end of the operation manual. The required stroke rate can be preselected (also during operation) using the thumbwheel 7. After working for longer periods at low stroke rate allow the machine to cool down by running it at maximum stroke rate and no-load for approx. Wear protective gloves to avoid injury from the sharp cutting edges of the saw blade both during assembly as well as when checking afterwards. When changing the saw blade, take care that the blade holder is free of material residue (e. By means of the adjustable orbital action, the contact of the saw blade can be adapted to the material to be worked. The saw blade is lifted from the workpiece on the downward stroke which improves chip ejection and increases the service life of the saw blade. The switching can be made with the machine running: If the saw blade seizes, switch machine off immediately. When using tools such as files and rasps or to achieve clean cutting edges. D / E) Plunge cutting may only be used on soft materials, such as wood, aerated concrete, gypsum plaster boards, etc. However, this requires a certain practise and is only possible with short saw blades. ­ When the required cutting depth is reached, move machine to a vertical position and continue to saw along the cutting line. For working with soft materials such as light building materials, insulation material, etc. F) Elastic bi-metal saw blades allow to saw off projecting building elements (e. Apply saw blade directly to the wall and bend slightly with some lateral pressure on machine so that base plate 2 rests on the wall. [. . . ] Important: If for any reason the moulded plug is removed from the cable of this machine it must be disposed of safely. Damage attributable to normal wear and tear, overload or improper handling will be excluded from the guarantee. In case of complaint please send the machine, undismantled, to your dealer or the Bosch Service Centre for electric power tools.
