General information 1. 1 Safety notices and their meaning -CAUTIONDraws attention to a potentially dangerous situation that could lead to minor personal injury or damage to the equipment or other property. 1. 2 Pictograms Warning signs Symbols General warning Read the operating instructions before use. Contents 1. [. . . ] ­ Check that no obstacles prevent communication between the PR 25 and the PRA 25. ­ Activate the auto alignment function by pressing the X or Y key three times within one second. when X (Y) is to be aligned with the reference point, auto alignment of the X (Y) axis must be enabled by way of the PRA 25. ­ As long as the PR 25 is not in line laser mode, it then switches automatically to medium rotation speed and begins the search process. The auto align function is indicated in the display by the axis currently being aligned and by blinking arrows. ­ The direction of the search process can be changed by pressing the direction arrows. ­ The beam moves to the zero point (reference plane) as soon as the laser beam strikes the target area on the PRA 25 detector. ­ After reaching this point (finding the reference plane), a signal sounds briefly indicating that the process is complete. If the process cannot be completed within a certain period of time, an error is indicated in the display. -NOTE- If an error is displayed Please check that the PRA 25 is positioned within the inclination range (+/­5°) and that no obstacles are located between the rotating laser tool and the laser detector. Manual alignment A basic prerequisite for manual alignment is that the PR 25 is set up accurately. The PR 25 must be set up so that the correct axis (X or Y) is positioned in the direction in which alignment is to be performed. The monitoring function is indicated in the display ­ the LEDs for the axis to be aligned and the arrows blink alternately. ­ The auto alignment process then begins as previously described. en 5 en ­ The auto alignment process stops as soon as the zero point has been found. In contrast to full auto alignment, no audible signal is emitted at the end of the process. ­ A check is carried out at regular intervals to ensure that laser plane has not been displaced. If it is found to have been displaced, the laser plane is again brought into alignment with the zero point (as long as the laser beam is still within the detector target area and line of sight between the rotating laser and the detector has not been interrupted for a long period). -NOTE- If an error is displayed Please check that the PRA 25 is positioned within the operating range (within a 5­50 m radius, inclination range +/­ 5°). Check that the line of sight between the two devices is not obstructed during the entire monitoring period. 6. 2. 2 Pairing It is possible to configure the PR 25 and the PRA 25 as a pair. When the two devices are paired, the rotating laser and the detector are assigned to each other. The rotating laser then receives commands only from its "own" detector/remote control unit. [. . . ] In many countries, Hilti has already made arrangements for taking back old tools and appliances for recycling. Ask Hilti Customer Service or your Hilti representative for further information. Should you wish to return the tool or appliance yourself to a disposal facility for recycling, proceed as follows: Dismantle the equipment as far as is possible without need for special tools. Separate the individual parts as follows: Part/assembly Housing Control panel, display Electronics Batteries Screws, small parts Main material Plastic Various Various Alkaline manganese Steel Recycling Plastics recycling Electronics scrap Electronics scrap * Scrap metal en * Dispose of batteries in accordance with national regulations.
