ENGLISH
Once the wall mount is secured, its steel plate provides a surface to
which the magnetic pivot bracket (f) can be attached. The position
of the laser can then be fine-tuned by sliding the pivot bracket up or
down on the wall mount.
ALIGNING THE VERTICAL BEAM – FINE ADJUST (FIG. 4)
The fine adjustment knob (h) on the top of the MLL 150 is for lining
up the vertical beams. Place the MLL 150 on a flat surface and turn
the knob to the right to move the beam to the right or to the left to
move the beam to the left.
Rotating the fine adjustment knob adjusts the entire internal
mechanism, maintaining the 90° angle between the two vertical
beams.

As long as the MLL 150 laser is properly calibrated, the laser is self-
leveling. Each laser is calibrated at the factory to find level as long
as it is positioned on a flat surface within average ± 4° of level. No
manual adjustments are required.
