USING THE LASER WITH THE WALL MOUNT (FIG. 3)
The laser wall mount (J)
FIG. 3
offers more mounting
options for the DW089
laser. The wall mount has a
clamp (K) at one end which
can be fixed to a wall angle
for acoustic ceiling
installation. At each end of
the wall mount is a screw
hole (L), allowing the wall
mount to be attached to
any surface with a nail or
screw.
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 DW089 is for lining up the vertical
beams. Place the DW089 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.
LEVELING THE LASER
As long as the DW089 laser is properly calibrated, the laser is self-

is positioned on a flat surface within average ± 4° of level. No manual
adjustments are required.
