or sustains significant impact, the user should check calibration by following these steps:
Calibrating the Top and Bottom Beams
1.Choose your recalibration site. To get the most accurate calibration possible, it is best to use a floor/ceiling distance greater than 10’ (the greater distance, the better the accuracy). Floor/Ceiling (top of doorway) distance of approximately 10’.

2.Turn the tool off.
3.Remove the calibration plug on the side of tool with a flathead
4.Draw a straight line on the ceiling.
5.Turn the tool on.
6.Place the tool on the floor (on its accessory so that you can see the down laser beam on the floor).
7.Align the tool so that the top laser beam hits the line on the ceiling.
8.Mark the down laser beam on the floor, Mark D. Mark the up laser beam on the ceiling, Mark E.
9.Rotate the tool 180 degrees and align the down beam with the mark on the floor.

10.Mark the up beam on the ceiling, Mark F. You should have two marks on the ceiling.
11.Compare the two marks on the ceiling. If the two marks are on the same point, the unit does not need to be calibrated. If the two marks are not on the same point, proceed to step 12.
12.Turn the tool off.
13.Insert the 2mm Allen wrench into the side calibration port. The objective is to get the laser beam halfway between the two marks on the ceiling. Turn the Allen wrench clockwise or counter clockwise to move the laser beam.
14.Turn the tool on and check the position of the beam to see if it is exactly halfway between the marks on the ceiling. If the beam is not correctly positioned, repeat steps
15.Plug the side calibration plug on the tool.
16.Calibration is complete.
