When A2 and A3 are more than 5 mm / 10 m apart, an 
adjustment is necessary. Contact your authorised dealer 
or else the UMAREX-LASERLINER Service Department.

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.

It is possible for you to check the calibration of the laser. To do this, 
position the device midway between 2 walls, which must be at 
least 5 metres apart. Do this by turning the unit on, thus releasing 
the transport restraint (cross laser on). See Section „Horizontal and 
vertical levelling“ about this.
1. Mark point A1 on the wall.
 2.  Turn the device through 180° and mark point A2. You now have 

a horizontal reference between points A1 and A2.

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.
