LASER LIGHT IS EMITTED FROM THIS APERTURE B A 1.3 Technical specifications Recommended Operating Distance 1,000 ft. (300 m) diameter Leveling Accuracy +/- 3/32’ at 100 ft. (+/- 7.5mm at 100 m) Leveling Range +/- 10%, 5.
GAT220-08-2007 7/10/07 22:38 Page 6 If the laser is disturbed while in H.I. Alert mode, the head will stop rotating, the beam will turn off, the LED indicator will be on continuously, and an alarm will sound for 30 seconds. Turn the laser off and turn it on again. Check to see if the beam elevation has changed from its original benchmark position. The laser is no longer in H.I. Alert mode. Press H.I. to return to H.I. Alert.

Charge it for 15 hours. Check and calibrate in this order: Check both sides of X axis. • If X is within spec, proceed to check both sides of Y. • If X needs calibration, calibrate X 3.3 Later recharges The CL250 can be charged when working, if electricity is available on the jobsite.

Rotate the laser 180 degrees so that X faces the wall. 5. Mark the location of the center of the beam near the first mark so that both marks are in line, one above the other. 6. At 100 ft., the marks should be no more than 3/16" apart (at 30m, no more than 5mm apart). This is within the stated accuracy of ±3/32" at 100 ft. (± 0.0075%). 7.
GAT220-08-2007 7/10/07 22:38 Page 12 Final X to Y Check As a final check, compare X and Y axes to be sure that your adjusted calibration is within the specs of ±3/32. The marks for X, X’, Y, and Y’ should be no more than 3/16" apart at 100 ft. (5 mm at 30 m). 4.3 Cone error checking 1. Set up your CL250 2 ft. or 1 meter from a wall (a) or a pole and 100 ft. or 30 meters from another wall or pole (b). 2. Turn the laser on. 3.
