User manual BOSCH PLL 360 REV 12-2009

[. . . ] This measuring tool produces laser class 2 laser radiation according to IEC 60825-1. Do not use the laser viewing glasses as safety goggles. The laser viewing glasses are used for improved visualisation of the laser beam, but they do not protect against laser radiation. Do not use the laser viewing glasses as sun glasses or in traffic. [. . . ] After switching on, the levelling function automatically compensates irregularities within the self-levelling range of ±4°. The levelling is finished as soon as the laser beams do not move any more. Because the surface on which the measuring tool stands deviates by more than 4° from the horizontal plane, the levelling warning indicator 9 lights up red and the laser is automatically switched off. In this case, bring the measuring tool to the level position and wait for the self-levelling to take place. As soon as the measuring tool is within the self-levelling range of ±4°, the levelling warning indicator 9 goes out and the laser is switched on. When not within the self-levelling range of ±4°, working with automatic levelling is not possible, because it cannot be assured that the laser lines run at a right angle to each other. In case of ground vibrations or position changes during operation, the measuring tool is automatically levelled in again. To avoid errors, check the position of the horizontal and vertical laser line with regard to the reference points upon relevelling. Working without Automatic Levelling (see figure E) When working without automatic levelling, press the "Lock" button 7. When the automatic levelling is switched off, indicator 11 lights up red. When the automatic levelling is switched off, the measuring tool can be held by hand or placed on an inclined surface. In cross-line operation, the two laser lines do not necessarily run at a right angle to each other. After switching on, the measuring tool is in crossline operating mode with automatic levelling. to change the operating mode , press the "Mode" button 8 until the requested operating mode is indicated by the corresponding illuminated operating-mode indication 10. The following operating modes are available: Indication Operating Mode Cross-line operation (see figures A, B and E): The measuring tool generates a horizontal laser plane (360° rotating laser line) and a vertical laser line. All three operating modes can be selected either with or without automatic levelling. 14 | English Laser Viewing Glasses (Accessory) The laser viewing glasses filter out the ambient light. This makes the red light of the laser appear brighter for the eyes. Do not use the laser viewing glasses as safety goggles. The laser viewing glasses are used for improved visualisation of the laser beam, but they do not protect against laser radiation. Do not use the laser viewing glasses as sun glasses or in traffic. The laser viewing glasses do not afford complete UV protection and reduce colour perception. [. . . ] Only for EC countries: Do not dispose of measuring tools into household waste!According the European Guideline 2002/96/EC for Waste Electrical and Electronic Equipment and its implementation into national right, measuring tools that are no longer usable must be collected separately and disposed of in an environmentally correct manner. Battery packs/batteries: Do not dispose of battery packs/batteries into household waste, fire or water. battery packs/ batteries should be collected , recycled or disposed of in an environmental-friendly manner.
