Controls And Displays Leveling knobs Use the leveling knobs to center the precision level vials (No. 5 and 10 below) for horizontal work (see pg. 8 for setting slope vial). The leveling knobs are also used during vertical alignment (see pg. 10) On / Off button When the on / off button is pressed, the laser beam will be projected.
Use the marks as a guide for later setups. Work as close to the laser as possible. You can work up to 500 feet (152 meters) from the L3 with the R5e receiver, or with the MC-1 machine control receiver. As with all instruments, the farther away you work, the more any error can build-up.
Maintenance Calibration There is no set interval for checking the calibration of the L3, but calibration should be checked from time to time in order to ensure that the highest possible quality of work is being done. Calibration should always be checked if the laser has been handled roughly or shipped by common carrier.
Note: The L3 transmitter is a class IIIa (less than 2.5mW) laser under the United States C.D.R.H. guidelines. The L3 is a class 3R laser under the 1993 IEC 825-1 laser safety standard (revised edition of the European Norm EN60825).

Note that there are three ways to project a level or sloped reference from the L3 , full 360º rotation, scanning beam and fixed beam. 360º rotation is used when working outdoors with a receiver (always use maximum rotation speed when working with a receiver), or when indoors and a full plane is needed (at any speed that allows visibility).
Plumb And Layout Setups When the is in vertical mode, it is completely manual in operation and will not turn off if it is disturbed (just as when it is in horizontal mode). Check the vertical vial and your benchmarks regularly to be sure your work will be accurate.
The mount can also be attached to a tripod for vertical setups. Check the vertical vial and your benchmarks regularly to be sure your work is accurate. The L3 is designed for vertical alignment up to two stories high.

• T-bar ceilings Vertical Alignment (see photo on page 10) Along with its ability to project a level reference plane, the L3 has a built-in manual vertical vial. When the L3 is in the vertical position, the vertical vial located under the window in the control panel is used to plumb the rotatable beam of laser light.
Magnetic Target The MT1 magnetic target is used to display the visible beam of the L3 and provide a relative position indication. Used when installing T-bar ceiling and steel stud wall framing, the magnetic target allows hands free alignment.
Checking And Adjusting Calibration Calibration should be checked from time to time. Although the L3 is calibrated at the factory and is an exceptionally rugged laser, it is well worth the effort to check calibration before you first use it (after shipping) and then from time to time to insure that you are doing the highest quality work possible.

Checking And Adjusting Calibration 7. Rotate the laser 90 degrees to aim the +Y-axis (control panel) at the target. Precisely re-level the bubbles in the precision level vials. Check the reading at the target. If the reading is on, or within tolerance of the true level mark, calibration is complete.
Troubleshooting The receiver does not pick-up the laser or performs strangely. • Be sure the laser is transmitting a beam (if in doubt, stop the rotation and view the laser spot on a target). Never look into the beam output window! Make sure that the laser beam is rotating (not scanning) and that the rotation speed is set to maximum.
