2en2. Description2.1 PR 25 rotating laserThe PR 25 is a rotating laser featuring a visible rotatinglaser beam plus a point laser beam set at 90° to the rotat-ing beam, which can be used to indicate the vertical,horizontal or inclined planes.2.2 FeaturesThe tool allows a single person to level or align in anyplane quickly and with great accuracy.Automatic leveling (within ±5° inclination): The tool lev-els itself automatically after switching on. The laser beamis emitted only when the specified accuracy has beenachieved.LEDs indicate the tool's operating status.Speed of rotationThe tool features 4 speeds of rotation. These are: sta-tionary spot (zero rotation), slow rotation, medium-speed rotation and fast rotation.It is possible to switch between functions such as “Rotat-ing laser” and “Line laser”. This can be done from thePR25 rotating laser or by way of the PRA 25 (combinedlaser receiver and remote control unit).Shock warningThe built-in shock warning function becomes active oneminute after switching on: The tool switches to warningmode (all LEDs blink, laser stops rotating) when broughtout of level as a result of vibration or an impact duringoperation. All LEDs blink and the laser stops rotating.Automatic cut-outIf movement of the mechanism is physically impededor the tool is set up outside its self-leveling range, thelaser remains switched off and all LEDs blink.The tool can be set up on a tripod with a 5/8″ thread orstood directly on some other steady surface (free ofvibration).-NOTE-In some versions sold, the PRA 25 is not supplied asstandard with the PR 25. In this case, the functions canbe controlled directly from the PR 25 rotating laser itself(excluding auto alignment/surveillance, which is possi-ble only in conjunction with the PRA 25).2.3 Description of functions2.3.1 Horizontal plane (automatic leveling)When switched on, the tool levels itself automatically byway of the 2 built-in servo motors for the X- and Y-direc-tions.2.3.2 Inclined plane (any desired inclination)Inclination can be set up in alignment with given marksby pressing the X- and Y-keys on the PRA 25 or PR 25.2.3.3 Automatic cut-outDuring automatic leveling in one or both directions, theservo system monitors compliance with the specifiedaccuracy.The tool switches itself off in the following situations:– Leveling is not accomplished (tool set up outside its leveling range or the mechanism is physicallyimpeded).– The tool is brought out of level (due to vibration or im-pact).After automatic cut-out, rotation of the laser beam stopsand all LEDs blink.Items supplied1 PR 25 rotating laser1 PRA 25 laser receiver*1 PR 25 operating instructions1 PRA 25 operating instructions*1 PR 25/PRA 25 operating instructions*1 PRA 50/1 target plate1 producer certificate3 batteries (size D cells)2 batteries (size AA cells)1 Hilti case* Depending on the version purchased, this may not beincluded in the items supplied.

7en7. Operation7.1 Switching the tool onPress the on/off key.7.2 Selecting the speed of rotationThe speed of rotation can be adjusted by pressing therotation speed control key (PR 25 or PRA 25). Afterswitching on, the PR 25 is set to rotate at medium speed,as standard.– Press the key once to set rotation to medium speed.– Press the key again to set rotation to high speed.– Press the key once more to return to medium speed.– Press the key yet again to set rotation to low speed.– A further press of the key stops rotation (spot).– The next press of the key sets rotation to low speed.– This procedure repeats itself.7.2.1 Selecting the line function After pressing the line function key, the PR 25 projectsa laser line. The line can be lengthened or shortened bypressing the key again.– Press the key once to project a short line.– Press the key again to project a medium-length line.– Press the key once more to project a long line.– Press the key yet again to project an extra-long line.– A further press of the key switches the tool back to thelong line.– The next press of the key switches the tool back to themedium-length line.– This procedure repeats itself.7.2.2 Moving the laser line and spotThe laser line or laser spot can be moved to the left orright by pressing the direction keys (PR 25 or PRA 25).Holding down the direction keys increases the speed ofmovement and the laser line or spot then move contin-uously.7.2.3 Working in the horizontal plane– Mount the tool suitably, depending on the application,e.g. on a tripod.– Press the on/off key.-NOTE-The laser beam switches on and begins to rotate as soonas the tool has leveled itself.7.2.4 Working in the vertical plane– Stand the tool on a level surface in a suitable positionfor the application.*– Press the on/off button.-NOTE-*In order to ensure that the specified accuracy is main-tained, the tool should be stood on an approximatelylevel surface.-NOTE-The X LED does not light (the X-direction is brought intovertical alignment automatically and monitored).The Y LED lights red (the Y-direction can be aligned man-ually by way of the servo keys, the laser plane remainsperpendicular).7.2.5 Automatic alignmentA basic prerequisite for auto alignment is that the PR 25is set up accurately. The PR 25 must be set up so thatthe correct axis (X or Y) is positioned in the direction inwhich alignment is to be performed. This can only bedone in conjunction with the PRA 25.Procedure:– Position the PR 25 at the reference point and with thecorrect axis in the direction in which alignment is tobe performed (the operating range for auto alignmentis a radius of 5-50 m).– Position the PRA 25 laser receiver at the desired point.– Check that no obstacles prevent communication betweenthe PR 25 and the PRA 25.– Activate the auto alignment function by pressing theX or Y key three times within one second. It is impor-tant that the axes correspond correctly, i.e. when X (Y)is to be aligned with the reference point, auto align-ment 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 thenswitches automatically to medium rotation speed andbegins the search process. The auto align function isindicated in the display by the axis currently beingaligned and by blinking arrows. An audible signal isemitted continuously during the search process.– The direction of the search process can be changedby pressing the direction arrows.– The beam moves to the zero point (reference plane)as soon as the laser beam strikes the detection areaon the PRA 25 laser receiver.– After reaching this point (finding the reference plane),asignal sounds briefly indicating that the process iscomplete. Only the axis that has been aligned is thenshown in the display.
8enIf the process cannot be completed within a certain periodof time, an error is indicated in the display.-NOTE- If an error is displayedPlease check that the PRA 25 is positioned within theinclination range (+/– 5°) and that no obstacles arelocated between the rotating laser and the laser receiver.7.2.6 Manual alignment with the PR 25 A basic prerequisite for manual alignment is that the PR 25 is set up accurately. The PR 25 must be set up sothat the correct axis (X or Y) is positioned in the direc-tion in which alignment is to be performed.Procedure:– Position the PR 25 at the reference point and with thecorrect axis in the direction in which alignment is tobe performed (the operating range for manual align-ment is a radius of 5–50 m).Setting the X-direction manually– Press one of the X-servo keys twice within 2 seconds.– The X-servo keys can then be used to perform man-ual alignment.-NOTE-The X LED lights red.Setting the Y-direction manually– Press one of the Y-servo keys twice within 2 seconds.– The Y-servo keys can then be used to perform man-ual alignment.-NOTE-The Y LED lights red.7.2.7 Manual alignment using the PRA 25A basic prerequisite for manual alignment is that the PR 25 is set up accurately. The PR 25 must be set up sothat the correct axis (X or Y) is positioned in the direc-tion in which alignment is to be performed.Procedure:– Position the PR 25 at the reference point and with thecorrect axis in the direction in which alignment is tobe performed (the operating range for manual align-ment is a radius of 5–50 m).– Check that no obstacles prevent communication between the PR 25 and the PRA 25.– Activate the manual alignment function by pressingthe X or Y key twice within 1 second. It is importantthat the axes correspond correctly, i.e. when X (Y) isto be aligned with the reference point, auto alignmentof the X (Y) axis must be enabled by way of the PRA 25.– The laser beam can be moved to the desired positionby pressing the direction keys. Holding down the direc-tion keys increases the speed of movement and thelaser line or spot then move continuously.– The manual alignment function is indicated in the dis-play by the axis currently being aligned and by sta-tionary (constantly lit) arrows. An audible signal is alsoemitted continuously during the search process.– The system switches to normal operation when no keyis pressed within 5 seconds. Only the axis that hasbeen aligned is then indicated in the display.7.2.8 SurveillanceThe surveillance function checks to ensure that no dis-placement of the aligned plane has occurred (e.g. dueto vibration). If displacement has occurred, the laserplane is realigned to the zero point (as long as it is stillwithin the detection area). An additional laser receiveris required for working with the surveillance function.A PRA 20 or PRA 25 may be used to detect the laserbeam.As surveillance begins by way of the auto alignmentfunction, the PR 25 must be 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 beperformed.Procedure:– Position the PR 25 at the reference point and with thecorrect axis in the direction in which alignment is tobe performed (the operating range for auto alignmentis a radius of 5–50 m).– Position the PRA 25 laser receiver at the desired point.– Check that no obstacles prevent communication betweenthe PR 25 and the PRA 25.– Activation of this function requires the PRA 25 to beswitched off. While pressing and holding the X or Ykey (the key for the axis you wish to align), switch onthe laser receiver by pressing the on/off key.– The system is then in surveillance mode. The moni-toring function is indicated in the display – the LEDsfor the axis to be aligned and the arrows blink alter-nately.– The auto alignment process then begins as previouslydescribed.– The auto alignment process stops as soon as the zeropoint has been found. In contrast to full auto align-ment, no audible signal is emitted at the end of theprocess.– A check is carried out at regular intervals to ensurethat laser the plane has not been displaced. If it is foundto have been displaced, the laser plane is again broughtinto alignment with the zero point (as long as the laserbeam is still within the detection area and line of sightbetween the rotating laser and the laser receiver hasnot been interrupted for a long period). In the event ofprolonged interruption of the line of sight between thetwo devices, an error is indicated after 30 seconds.
9en-NOTE- If an error is displayedPlease check that the PRA 25 is positioned within theself levelling range (+/– 5°) and that no obstacles arelocated between the rotating laser and the laser receiver.After successfully setting to the zero point, take care toensure that the line of sight between the two devices isnot interrupted.7.2.9 PairingIt is possible to configure the PR 25 and the PRA 25 asa pair. When the two devices are paired, the rotating laserand the detector are assigned to each other. The rotat-ing laser then receives commands only from its “own”detector/remote control unit. The devices can be pairedby pressing and holding down the on/off keys on bothdevices simultaneously.-NOTE-The PR 25 and PRA 25 are not paired when supplied.Each unpaired rotating laser receives commands fromany unpaired laser receiver.Pairing procedure:– The devices can be paired by pressing and holdingdown the on/off keys on the PR 25 and PRA 25 simul-taneously, as previously described, for more than 3seconds. Successful pairing is confirmed by an audi-ble signal emitted by the PRA 25 and by the LEDs onthe PR 25 blinking.Cancelling pairing:– Pairing can be cancelled by pressing and holding downthe on/off keys for more than 3 seconds. Cancellationof pairing can only be successful when the on/off keyson the PR 25 and PRA 25 are not pressed simultane-ously. Successful cancellation of pairing is confirmedby the PRA 25 by the emission of an audible signaland by the symbol “!” displayed. The PR 25 confirmscancellation of pairing by causing all LEDs to blink.7.2.10 Working with the target plate The target plate improves visibility of the laser beam.The target plate for the PR 25 is particularly useful inbright conditions or wherever better visibility of the laserbeam is required.7.2.11 Working with the laser receiverPlease refer to the PRA 25 operating instructions forinformation about the laser receiver.7.2.12 Continuing work in manual mode after arestartIn order to continue working in manual mode after arestart, it is necessary to press one of the “servo” keyson the PR 25 within 3 seconds.7.2.13 Returning to standard modeTo return to standard mode, switch the tool off and thenrestart it.
