Operating Instructions for General Construction Applications
NOTE: A level plane of laser light is created by the rotating beam of the laser. The laser light can be
used to reference elevations with the use of a laser detector. (Fig. 4)
1. Place the instrument on a flat, level surface such as a tripod. Setup the instrument in an
area where it can not be obstructed and is set at a convenient height.
2: Press the (A) button. Allow the instrument to self-level.
3. Setup a "Benchmark" .
4. ALHV, ALHV-G ALGR Only – Set the Variable Speed Rotation (page 14 ) to the desired
rotation speed of the laser head. Ideal speed for use with laser detector is 600 RPM.
5. Take elevation readings using the plane of laser light as a reference.Follow the Detector
Operation Procedures in this manual.
Ceiling Grid Applications
1. Attach the laser to the optional wall-mount bracket. Be sure the control buttons are facing
outward. Tightening the locking screw will secure the instrument to the bracket.
2. After installing the first piece of ceiling trim, attach the wall-mount to it. Be sure the
wall-mount is secure to the trim.
3. Press the (A) button. Allow the instrument to self-level.
4. Adjust the distance of the instrument from the grid, typically 1.5-inch (38mm) below the grid.
Loosen the adjustment screw and slide the instrument up/down on the wall mount. When
the desired height has been reached, tighten the adjustment screw to secure the instrument.
5. Setup a "Benchmark" (page 11).
6. Install the ceiling grid. Attach the magnetic laser target to the ceiling trim being installed.
Adjust the height of the trim until the laser beam strikes the target.(Fig. 5)
Laydown Applications (ALHV, ALHV-G, ALGR)
1. Place the instrument in the laydown position on a flat, level surface.
2. Press the (A) button. Allow the instrument to self-level.(Fig. 6)
3. Setup a "Benchmark" (page 11).
