Performing the calibration check
3. Position the device as near as possible to the wall
at the height of point A1.
4. Turn the device through 180° and mark point A3.
The difference between points A2 and A3 is the tolerance.

! When A2 and A3 are more than 0.5 mm / m apart, an
adjustment is necessary. Contact your authorised dealer
or else the UMAREX-LASERLINER Service Department.
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 ± 2.5 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
± 2.5 mm. Repeat the process by turning the laser to the left.
!
Regularly check the calibration before use, after
transport and after extended periods of storage.
