5.15 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, please return the tool to Hilti Service for calibration.
5.16 Checking the vertical axis
1. Place the tool in the vertical position on the floor or ground, which should be as flat as possible, approx.
20 m (66 ft) from a wall.
2. Align the grips parallel to the wall.
3. Switch the tool on and mark the reference point (R) on the ground or floor.
4. With the aid of the receiver, mark point (A) low on the wall.
5. With the aid of the receiver, mark point (B) at a height of approx. 10 m (33 ft).
6. Pivot the tool through 180° and realign it with the reference point (R) on the ground or floor and with point
(A) at the base of the wall.
7. With the aid of the receiver, mark point (C) at a height of approx. 10 m (33 ft).
▶ When this procedure is carried out carefully, the horizontal distance between the two marked points
(B) and (C) should be less than 1.5 mm (at 10 m) (0.06 inch at 33 ft). If the deviation is greater than
this, please return the tool to Hilti Service for calibration.
