Maintenance and Service
Out of Level. If the laser is tilted too
much and can not self-leveling (>5°),
the flashing laser beams will indicate
the laser is not plumb. Try to reposition
the laser on a level surface.
Using the Laser to Plumb. (Fig. 1)
To transfer a point from the floor to the
ceiling, center the plumb down beam
over the point you wish to transfer. The
laser will project a bright laser beam on
the ceiling. Mark the point as required.
Using the Laser to Square. (Fig. 2)
Place the unit on the floor or a fairly
level surface near the walls or the
objects to be squared. Measure from
one wall to the laser beam at two
points. One point near the unit and
at another point farther away. (Note: the
greater the distance between the two
points the greater the possible
accuracy). Rotate the unit until the two
measurements are equal. Do not move
the unit until the rest of the measuring
is completed. Now take two
measurements from the other wall to
that laser beam. If the measurements of
these two points are the same, then the
walls are square. If they are not equal,
move the second wall until the two
measurements are equal.
You can also square vertical surfaces to
horizontal surfaces by using a plumb
beam and a level beam.
Using the Laser to Level. Set the unit
on a surface that is at a convenient
height for marking a level reference
plane on walls or other surfaces. The
laser will generate a horizontal point of
referece onto the surface.
