MAINTENANCE
This laser level left the factory fully calibrated. Kapro
recommends checking the accuracy of the laser periodically,
or if the unit falls or is mishandled.
To do so, first check the height accuracy of the horizontal
line, then check the leveling accuracy of the horizontal line,
and finally 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 flat 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
