2. Set the laser on a flat, horizontal surface approx. 20 cm from wall (A) and project the point of intersection of the laser lines on to wall (A).
3. Mark the point of intersection of the laser lines with a cross (1) on wall (A) and with a cross (2) on wall (B).
4. Place the laser on a flat, horizontal surface approx. 20 cm from wall (B) and project the point of intersection of the laser lines on to cross (1) on wall (A).
5. Adjust the height of the point of intersection of the laser lines so that the point of intersection coincides exactly with mark (2) on wall (B). Use a tripod or a wall mount if necessary.
6. Mark the point of intersection of the laser lines again with a cross (3) on wall (A).
7. Measure the offset D between crosses (1) and (3) on wall (A) (RL = room length).
8. Calculate the value R.
   • The value R should be less than 3 mm (1⁄8).
9. If the result is out of tolerance, consult Hilti Service.

**Checking the accuracy of the horizontal line 10, 11

**

1. Place the tool at the edge of a room that is at least 10 m in length.
   The floor surface must be smooth and horizontal.

2. Switch all the laser beams on and make sure that the pendulum lock is disengaged.

3. Make a mark at a distance of at least 10 m from the tool, so that the point of intersection of the laser
   lines coincides with the center of the mark (d0) and the vertical line of the mark runs exactly through the middle of the vertical laser line.

4. Pivot the tool 45° clockwise, as viewed from above.

5. Then mark the point (d1) on the mark where the horizontal laser line coincides with the vertical line of the mark.

6. Pivot the tool 90° counter-clockwise.

7. Then mark the point (d2) on the mark where the horizontal laser line coincides with the vertical line of the mark.

8. Measure the following vertical distances: d0-d1, d0-d2 and d1-d2. Determine the largest difference (dmax) and the smallest difference (dmin).

9. For d0-d1, d0-d2 and d1-d2 the following applies:

10. The largest vertical measured distance must be no greater than 5 mm at a working distance of 10 m.

    • dmax-dmin = distance between the highest mark and the lowest mark in millimeters/¹⁄₁₀ inch
    • D = distance between the tool and the mark in meters/feet

**Checking the accuracy of the vertical line 12, 13

**

This check requires a doorway or similar opening with a clear height of at least 2 m. At least 2.5 m space on each side is also needed

1. . Switch the tool on and make sure that the pendulum lock is disengaged.

2. Place the tool on the floor at a distance of 2.5 m from the door opening and align the vertical line with the middle of the doorway.

3. Mark the middle of the vertical line on the floor (1) and the top edge of the doorway (3) and on the floor at a distance of 2.5 meters past the doorway (2).

4. Place the tool immediately behind point (2) on the floor and align the laser beam to pass through points (2) and (1).

5. The deviation between the laser line and point (3) can be read off directly at the top edge of the doorway.
   This value corresponds to the deviation at twice the height.

6. Measure the height of the doorway.

7. The maximum permissible deviation is 3 mm per 10 m of height.

8. For the deviation obtained by the above method, the maximum permissible deviation is as follows:

9. The maximum permissible calculated deviation in millimeters must be less than 0.3 mm/m multiplied
   by twice the height in meters.

   • d = twice the measured deviation in millimeters/ ¹⁄₁₀ inch
   • H = doorway height in meters

Dealing with deviations

• If you find that deviations occur, consult Hilti Service.
