[. . . ] 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. [. . . ] The trade names of the individual measuring tools may vary. When inserting, pay attention to the correct polarity according to the representation on the inside of the battery compartment. always replace all batteries at the same time. Only use batteries from one brand and with the identical capacity. Remove the batteries from the measuring tool when not using it for extended periods. When storing for extended periods, the batteries can corrode and discharge themselves. 12 | English Working with Automatic Levelling (see figures A­B) Position the measuring tool on a level and firm support, hold it by the contact surfaces 6 against a vertical surface or attach it to a tripod 11. 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 indicator 2 lights up red and the laser is automatically switched off. In this case, bring the measuring tool to the level position or hold it by the contact surfaces 6 straightly against a vertical surface, and wait for the selflevelling to take place. As soon as the measuring tool is within the self-levelling range of ±4° again, the indicator 2 lights up green and the laser beams are switched on. When not within the self-levelling range of ±4°, working with the measuring tool is not possible, because it cannot be assured that the laser beams 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 re-levelling. Laser viewing glasses (Accessory) The laser viewing glasses filter out the ambient light. [. . . ] 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. [. . . ]
