MAINTENANCE
This laser level left the factory fully calibrated. Kapro
recommend that the user will check the accuracy of the laser
periodically, or if the unit falls or is mishandled.
To do so rst check the height accuracy of the horizontal
line, then check the leveling accuracy of the horizontal line,
and nally check the leveling accuracy of the vertical line.
Checking the Height Accuracy of the Horizontal Line.
(Up and down deviation)
1) Set up the laser on a tripod or on a solid surface between
two walls A and B, approximately 5 meters apart.
2) Position the laser level approximately 0.5 meter from wall A
3) Unlock the pendulum and press the button to project the
horizontal and the vertical cross lines towards wall A.
4) Mark on the wall the center of the cross lines as a1
(see gure 1).
