1. Product information Functional description, continued Automatic cut-out In the case of automatic levelling of one or both directions, the servo system monitors adherence to the specified accuracy. Cut-out takes place: - if levelling is not achieved (levelling range exceeded or mechanical blockage) - if the tool is put out of plumb (shock/jolt).

Only then can the tool be operated safely. Laser classification The PR 15 rotating laser corresponds to laser safety class 2, based on the standards IEC825-1 / EN60825, and class II based on FDA 21 CFR. The eyelid closure reflex protects the eyes should anyone happen to look briefly into the laser beam.
- aligning equipment and elements in three axes. Electromagnetic compatibility (EMC) Although the Hilti PR 15 fulfils the strict requirements of the applicable directives, Hilti cannot completely exclude the following possibilities: - The PR 15 may cause interference which affects other equipment (e.g.
- Check the tool for possible damage before use. If the tool is damaged, have it repaired by a Hilti service centre. - If the tool has been dropped or subjected to other mechanical forces, its accuracy should be checked.
Page 20
- Although the tool is moisture resistant, it should be wiped dry before being put away in its carrying case. - The tool should be repaired only by Hilti service centres. Radiation in excess of class 2 may be emitted if the correct procedures are not observed when the casing is opened.

Checking horizontal rotation Checking the horizontal alignment of the PR 15 1 Set up the tripod at the mid point between wall A and wall B. The distance between A and B should be approx.
Page 28
4. Checks Checking horizontal rotation, continued 7 Loosen tripod screw a little and carefully turn the tool through 180°, taking care not to displace the tripod. Fix the tool on again. 8 Switch on using ON/OFF button 9 Using the beam catcher, mark the height of the reference line on walls A and B, marks A2 and B2.
Page 29
4. Checks Checking horizontal rotation, continued To check the other two directions, proceed in similar fashion: - Measure the first reference line in the position and then the second in the position Here too, the two markings must deviate by no more than 6 mm.
4. Checks Checking vertical rotation Procedure 1 Set up tool and switch on. 2 Set mode to 0 rpm using Speed button 3 Turn rotating head manually and mark a point A on the wall near the floor. 4 Turn the rotating head upwards and mark point B. 5 Turn the tool around 180°, and set the laser beam to point A again.
4. Checks Making adjustments Adjusting the tool - Adjustment of the PR 15 rotating laser should be carried out only by trained and experienced personnel. - Accuracy cannot be guaranteed if the adjustment instructions are not followed precisely. - The tool must be adjusted in all three axes (X, Y, Z).

Page 35
After calibration, the accuracy of the tool should be checked once more. If the Operation LEDs flash red alternating with green and the orange Incline LED, please contact your local Hilti agent.
2 Set up the tool 1 to 2 metres in front of wall A and align it horizontally. 3 Mark the reference lines at points a’ and b’. The differential value between Db and Da must be ≤ 4 mm. In the event of deviations > 4 mm, please contact your local Hilti agent.
5. Accessories 5. Accessories Manual detector At distances of greater than 30 metres and when lighting conditions are unfavourable, a manual detector should be used to detect the laser beam.
