g. Using the infra-red viewer to see the beam on the far point, adjust the
laser to center it's beam on the center of the mark made in step e.
h. If the vertical vial is not indicating level, loosen one of the screws that
attach the vial holder and pry the holder until a level indication is
achieved.
i. Tighten both screws and check that the laser is still on the mark and that
the bubble is still indicating level.
j. Re-install housing (see procedure #102) and check laser calibration.
2. Procedure without Infra-Red viewer.
a. Without removing the housing, attach the laser to the vertical mounting
accessory (model V1).
b. Set the laser so that its vertical plane of light is projecting
perpendicular to a wall about 30 feet (10 meters) away. The wall should
be as high as you have the ability to reach to the top. 15 feet (5 meters) is
sufficient. Level the vertical vial.
c. Using the laser receiver, make a mark at the bottom of the wall
indicating beam center. For maximum accuracy, make two marks at the
points where you just get an on-grade indication as you come in from each
side. Use the middle of the two marks for center.
d. Now, make a mark (or set of marks) at the top of the wall.
f. Return to the laser and turn it 180° so that the beam is projecting toward
the wall from the opposite side of the laser. Set the receiver at the bottom
mark and use the X axis leveling screw to align the laser to the receiver.
Re-level the vertical vial. Use the receiver to check the top mark(s). if
there is an error of more than 1/8 inch in 25 feet (3.2mm in 7.5 meters),
the sensor should be adjusted.
g. To adjust the vial, loosen the three screws that attach the housing to the
reference plate, but keep them just tight enough to hold the housing
against the reference plate. Align the laser with the bottom mark again.
Now, make a mark half between the two top marks made earlier. This
mark represents true vertical. Use the S axis leveling screw to adjust the
laser until it is in alignment with the top (true vertical) mark. Check that
the laser is still aligned with the bottom mark. Carefully remove the
housing and tilt the housing back just enough to allow
access to the vertical vial.
h. Loosen one of the screws that attach the vial holder and pry the holder
until a level indication on the vial is achieved.
i. Tighten both screws and check that the bubble is still indicating level.
j. Re-install housing (see procedure #102) and re-check the vertical
alignment.
