  • Page 10: Operating Instructions

    OPERATING INSTRUCTIONS Working in Automatic mode (self-leveling): In Automatic mode, the laser will level itself in a ± 3° range and project horizontal, vertical or both lines simultaneously 1. Remove the laser from the case and place it on a solid, flat, vibration free surface or on a tripod.
  • Page 11 Working in Manual mode: In Manual mode the 872G’s self-leveling mechanism is disabled and the laser lines can be set at any slope required. The laser beams will flash every 3 seconds to let you know that you are working outside the self-leveling range and the beams may not be leveled.
  • Page 12 Working in Pulse mode with a detector: For outdoor work, under direct sunlight, bright conditions or for extended indoor ranges up to 60 meters, use the Pulse mode with a Detector. When the Pulse mode is activated, the laser lines will flash at very high frequency (invisible to the human eye) allowing the detector to detect the laser lines.

  • Page 13: Maintenance

    MAINTENANCE To maintain the accuracy of your project, check the accuracy of your laser level according to the field calibration tests procedures. • Change the batteries when the laser beams begins to dim. • Wipe the aperture lens and the body of the laser level with a clean soft cloth.

  • Page 14: Field Calibration Test

    FIELD CALIBRATION TESTS This laser level left the factory fully calibrated.

Check the leveling accuracy of the horizontal beam.
  • Page 15 5) Turn the laser 180° towards wall B and mark the center of the cross beams as b1 on the wall (see figure 2). 6) Move the laser level towards wall B and position it approximately 0.5 meter from wall B. 7) Mark on wall B the center of the cross beams as b2 (see figure 3).
  • Page 16 8) Turn the laser 180° towards wall A, and mark on the wall the center of the cross lines as a2 (see figure 4). 9) Measure the distances: Δa= |a2-a1| Δb= |b1-b2| 10) The difference | Δa – Δb| should be no more than 2 mm, otherwise send the laser level to a qualified technician for repair.
  • Page 17 3) Mark point a1 on the wall, in the middle of the horizontal line at the left edge of the horizontal beam (see figure 5). 4) Turn the laser level counterclockwise until the right edge of the horizontal line reaches near a1, mark a point a2 on the wall in the middle of the horizontal beam (see figure 6).
  • Page 18 5) The distance between a1 and a2, should be no more than 1 mm, otherwise, send the laser level to a qualified technician for repair. Checking the Accuracy of the Vertical beam. 1) Hang an approximately 4 meter/13 feet plumb line on a wall. 2) After the plumb line has settled, mark point a1 on the wall behind the plumb line, near the plumb cone.
  • Page 19 6) Mark point a2 on the wall, in the middle of the vertical beam at the same height as a1. (see figure 8). 7) The distance between a1 and a2, should be no more than 1mm, otherwise send the laser level to a qualified technician for repair.
