Remove the batteries from the measuring tool when not using it for extended periods. [. . . ] Working with Automatic Levelling (see figure F­G) Position the measuring tool on a level and firm support, attach it to the wall mount 13 or to a tripod 12. 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 lines or plumb 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 automatic levelling indicator 4 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° again, the operating-mode indication 5 lights up green 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 laser lines or plumb beams with regard to the reference points upon re-levelling. Working without Automatic Levelling When automatic levelling is switched off, you can hold the measuring tool freely in your hand or place it on an inclinded surface. English | 15 Turn the mounted measuring tool in such a manner that the bottom plumb beam 3 faces downward. If required, lightly fold up the holding plate again to loosen the 1/4" screw 17 for alignment of the measuring tool. Laser Viewing Glasses (Accessory) The laser viewing glasses filter out the ambient light. The laser viewing glasses are used for improved visualisation of the laser beam, but they do not protect against laser radiation. The laser viewing glasses do not afford complete UV protection and reduce colour perception. Working with the Tripod (see figure H) A tripod 12 offers a stable, height-adjustable measuring support. [. . . ] 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.
