2. Press the
button.
▶ The shock warning deactivation LED lights constantly, indicating that the function has been
deactivated.
To return to standard operating mode, switch the laser tool off and then switch it back on again.
5.6 Checking the main and transverse horizontal axes
1. Set up the tripod approx. 20 m (66 ft) from a wall and adjust the tripod head horizontally with a spirit level.
2. Mount the tool on the tripod and use the visual sighting method (front and rear sights) to aim the tool at
the wall.
3. Fig. a: Use the receiver to catch the laser beam and mark a point (point 1) on the wall.
4. Pivot the tool clockwise through 90° about its own axis. In doing so, ensure that the height of the tool
does not change.
5. Fig. b: Use the laser receiver to catch the laser beam and mark a second point (point 2) on the wall.
6. Fig. c and d: Repeat the two previous steps twice and use the laser receiver to catch the beam and mark
points 3 and 4 on the wall.
If the procedure has been carried out accurately, the vertical distance between the two marked
points 1 and 3 (main axis) or points 2 and 4 (transverse axis) should each be < 2 mm (at 20 m) (0.12" at
66 ft). If the deviation is greater than this, the tool should be returned to Hilti Service for calibration.
