SuperCross-Laser 2
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.

Note:
If points A2 and A3 are more than 5 mm / 10 m, the device is in need of calibration. Contact
your authorised dealer or else the UMAREXLASERLINER 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 deviati-
on 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.

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.

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
