CROSSLINE LASER LEVEL
CHECKING THE VERTICAL LINE
1. Position the device about 5 m from a wall. Fix a plumb bob with a line of 2.5 m length on
the wall, making sure that the bob can swing freely.
2. Switch on the device and align the vertical laser to the plumb line. The precision is within
the specified tolerance if the deviation between the laser line and the plumb line is not
greater than ± 2mm.
CHECKING THE HORIZONTAL LINE
1. Position the device about 5m from a wall and switch on the cross laser.
Mark point B on the wall.
2. Turn the laser cross approx. 2.5 m to the right and mark point C.
3. Check whether the horizontal line from point C is level with point B to within ± 2 mm.
