Position the laser so that it's appropriate for your application needs. If necessary, align the laser beam(s) with a reference point(s). [. . . ] Wearing them longer than necessary can affect your eyes' sensitivity to seeing color. Checking Calibration Before each use, be sure to check the laser for signs of damage. If the laser has been dropped or subjected to other rough treatment, it should be checked for accuracy. Refer to the sketch for the location of the laser at each step and for the location of the marks made at each step. All marks can be made on the floor by following the beam to the floor. Locate an area at least 10 m x 5 m (30 ft x 15 ft) 1. Mark a point (A) on the floor at one end of the room. Place the laser so that the laser beams intersect over point A with one of the beams pointing toward the far end of the room. Mark a point (B) on the floor at about the center of the room, on the laser line. Note: To ensure accuracy, the distances from B to A, to C, and to D should be equal. Mark a point (C) on the far wall close to or on the floor. Place the laser so that the laser beams intersect over point B, making sure that one of the beams is on point C. Turn the laser 90° so that the intersecting laser beams are over point B, making sure that one beam is over point D and the other is pointing in the direction of point A. Mark point E as close as possible to point A. Measure the difference between points A and E and compare with the following: 90° angle is in calibration if the distance between A and E is: 10 m (30 ft) <3 mm (<1/8 inch) If the difference is more than shown in the chart, contact your local authorized service center for exchange or replacement.

However well the product is designed, mishaps do occur and the most common problems associated with these are covered in the following areas. Any damage to the laser caused by improper maintenance and care voids the warranty. Handling Precautions When transferring the laser from one location or job site to another, be sure to carry it in its protective carrying case. System Cleaning For maximum performance and accuracy always keep the lenses clean. Use only a good quality glass cleaner on a soft cloth to clean the exterior of the laser, its lenses, and the laser glasses. CAUTION: A dry cloth or abrasive organic cleaner could scratch or damage these surfaces. Storage When you're not using the laser, store it in its protective case. [. . . ] Customers should send products to the nearest Authorized Factory Service Center for warranty repairs, freight prepaid. In countries with Trimble Service Subsidiary Centers, the repaired products will be returned to the customer, freight prepaid. Any evidence of negligent, abnormal use, accident, or any attempt to repair equipment by other than factory-authorized personnel Trimble certified or recommended parts, automatically voids the warranty. Special precautions have been taken to ensure the calibration of the laser; however, calibration is not covered by this warranty. [. . . ]
