Safety instructions

Using class 2 lasers



  • Do not look into the direct or reflected beam.
  • Do not point the laser beam towards persons.
  • If a person‘s eyes are exposed to class 2 laser radiation, they should shut their eyes and immediately move away from the beam.
  • Under no circumstances should optical instruments (magnifying glass, microscope, binoculars) be used to look at the laser beam or reflections.
  • Do not use the laser at eye level (1.40 … 1.90 m)
  • Reflective, specular or shiny surfaces must be covered whilst laser devices are in operation.
  • In public areas shield off the laser beam with barriers and partitions
Safety instructions
  • Dealing with electromagnetic radiation
  • The measuring device complies with electromagnetic compatibility regulations and limits in accordance with the EMC Directive 2014/30/EU.
  • Local operating restrictions – for example, in hospitals, aircraft, petrol stations or in the vicinity of people with pacemakers – may apply. Electronic devices can potentially cause hazards or interference or be subject to hazards or interference.

Special product features and functions

The rotary laser aligns itself automatically. It is set to the required initial position (to within an operating angle of ± 4°) and the automatic system then performs the necessary fine adjustment, with three electronic measurement sensors detecting the X, Y and Z axes.

The anti-drift system (ADS) prevents erroneous or inaccurate measurements. How it works: continuous monitoring of the alignment of the laser is activated 30 seconds after the ADS is switched on. If the device moves due to the influence of external factors or the laser loses its height reference, the laser will come to a standstill. Additionally, the laser flashes and the tilt LED is lit continuously. To continue working, press the tilt button again or switch the device off then on again. Erroneous and inaccurate measurements are thus prevented simply and reliably. The ADS is not active following switch-on. Once the device has been set up, press the tilt button to activate the ADS, enabling you to protect the laser from changes in position caused by the device being disturbed by external factors. The tilt LED flashes to indicate that the ADS function is active; see the diagram below.


The ADS does not activate the monitoring function until 30 seconds after the laser levelling procedure has been completed (set-up phase). The tilt LED flashes every second during the set-up phase, rapid flashing, when ADS is active.

Green laser technology

The DLD laser modules produce a high quality, green laser light. Unlike previous generations they are more temperature stable and energy efficient. Furthermore, the human eye has a higher sensitivity to the wave range of the green laser than the red laser, for example. Thismakes the green laser diode appear much brighter than the red one. Green lasers, especially in the DLD design, thus offer advantages with regards to how visible the laser line is under unfavourable conditions.

Battery charging

  • Use the power supply/charger unit only in closed rooms; do not expose to moisture or rain otherwise risk of electric shock.
  • Charge the device‘s battery completely prior to use. – Connect the power pack/charger to the mains power supply and socket (G). Please only use the power
  • pack/charger supplied. Using any other power pack/charger will invalidate the warranty.
  • The LED on the power pack/charger (H) lights red while the battery is charging. When the LED changes to green, charging is complete. The LED on the power
  • pack/charger (I) flashes when the laser is not connected to the power pack/charger.
  • The battery can also be charged while using the device.
  • The status indicator (4) flashes when the battery charge is low.

Horizontal leveling and vertical levelling

  • Horizontal: Position the device on a level surface or on a tripod.
  • Vertical: Place the device on its side with the stand and wall bracket fitted. The operator panel should be at the top. The device with the stand and wall bracket can be
  • mounted on a tripod for vertical use.
  • Press the „ON/OFF“ switch

auto/slope function LED OFF: Automatic alignment

  • The device levels itself automatically to within a range of ± 4°. During the set-up phase, the laser flashes and the prism head remains stationary. When levelling is complete, the laser lights up continuously and rotates at maximum speed. Refer also to the sections about „Sensor Automatic“ and „ADS Tilt“

If the device has been placed on a surface with a slope of more than 4°, the prism head will remain stationary and the laser as well as the auto/slop LED will start to flash. The device must then be placed on a  more even surface

Slope function
Steeper slopes can be set using the angle plate, which is available as an optional extra (product ref. 080.75). TIP: Allow the device to align itself automatically and set the angle plate to the zero position. Then press the auto/slope button to switch the automatic sensor off. Finally, incline the device  to the angle you require.

Auto/slope function LED ON: Manual alignment

Laser modes

Rotary mode
The following speeds can be set using the rotary button: 0, 30, 330, 600 rpm

Spot mode
You access spot mode by pressing the rotary button repeatedly until the laser stops rotating. The laser can then be rotated to the required position using the positioning buttons.

Scan mode
The scan button can be used to activate and set a lightintensive segment in 4 different widths. You position the segment via the direction buttons.

Hand receiver mode
Working with the laser receiver (available as an optional extra): Set the rotary laser to maximum speed and switch on the laser receiver. Refer to the operating instructions for the respective laser receiver about this.

Working with the reference laser
The device has one reference laser. In vertical mode the reference laser is used to align the  device. Align the reference laser parallel to the wall for this purpose. This aligns the vertical laser plane at a right angle to the wall, see illustration.


EU directives and disposal
This device complies with all necessary standards for the free movement of goods within the EU. This product is an electric device and must be collected separately for disposal according to the European Directive on waste electrical and electronic equipment.

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. Switch the device on. The best calibration results are achieved if the device is mounted on a tripod. IMPORTANT: The automatic sensor must be active (auto/slope LED is off).

  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.

FIG-16 Performing the calibration check

  1. Position the device as near as possible to the wall at the height of point A1. Now adjust the device in the X axis.
    4. Turn the device through 180° and mark point A3. The difference between points A2 and A3 is the tolerance for the X axis.
    5. To check the Y and Z axis, repeat steps 3 and 4


If points A2 and A3 are more than 0.15 mm / m apart on either the X or Y axis, the device is in need of adjustment. Contact your ! authorised dealer or else the UMAREX-LASER LINER Service Department.

Adjustment mode

  • Take the alignment of the rotary laser into account when performing adjustment work.
X-axis adjustment
  • Activate adjustment mode: Switch on the Cubus. Simultaneously press the ON/OFF button and the auto/slope button until the LED auto/slope flashes rapidly.

Adjustment: Use the positioning buttons to move the laser from its current position to the height of reference point A2. Keep pressing the positioning buttons at second
intervals until the required position is reached.

  • Cancel adjustment: Switch the device off.
  • Save: Pressing the scan button saves the new adjustment settings
Adjust the Y and Z axes
  • Activate adjustment mode: Switch on the Cubus. Simultaneously press the ON/OFF button and the auto/slope button until the LED auto/slope flashes rapidly.

  • Switch to the Y axis using the tilt button. (LED auto/slope)

  • Adjustment: Use the positioning buttons to move the laser from its current position to the height of reference point A2. Keep pressing the positioning buttons at second intervals until the required position is reached.

  • Cancel adjustment: Switch the device off.

  • Save: Pressing the scan button saves the new adjustment settings

  • To adjust the Z axis, set up the device vertically and proceed in the same manner as for the X axis adjustment.

Regularly check the adjustment before use, after transport and after extendedperiods of storage. Always make sure to control all axes.
