Always keep these operating instructions together with the tool. Ensure that the operating instructions are with the tool when it is given to other persons.

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. [. . . ] ­ A further press of the key switches the tool back to the long line. ­ The next press of the key switches the tool back to the medium-length line. ­ Press the key once more to switch to a short line. ­ Press the key again to project a laser spot. 6. 1. 8 Moving the laser line and spot The laser line or laser spot can be moved to the left or right by pressing the direction keys. Holding down the direction keys increases the speed of movement and the laser line or spot then move continuously. 4 6. 1. 9 Automatic alignment A basic prerequisite for auto alignment is that the PR 25 is set up exactly according to instructions. 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. This can only be done in conjunction with the PRA 25. Procedure: ­ Position the PR 25 at the reference point and with the correct axis in the direction in which alignment is to be performed (the operating range for auto alignment is a radius of 5­50 m). ­ Position the PRA 25 laser detector at the desired point. ­ 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. It is important that the axes correspond correctly, i. e. 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. An audible signal is emitted continuously during the search process. ­ 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. Only the axis that has been aligned is then shown in the display. If the process cannot be completed within a certain period of time, an error is indicated in the display.
