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.
