Preparing the calibration check:
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). Please use a tripod.
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.

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 0.2 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 ± 1 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 ± 1 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.
