Checking the vertical line:

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. 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 ± 1.5 mm.

Checking the horizontal line:

Position the device about 5 m from a wall and

switch on the cross laser. Mark point B on the

wall. Turn the laser cross approx. 2.5 m to the

right and mark point C. Check whether the

horizontal line from point C is level with point B to within ± 2 mm.

Repeat the process by turning the laser to the left.

Regularly check the adjustment before use, after transport and after

extended periods of storage.
