instructions
Using class 2 lasers
- Attention: 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 wherever possible and identify the laser area with warning signs.
- Tampering with (making changes to) the laser device is not permitted.
- This device is not a toy – keep out of the reach of children.
Always turn off all lasers and latch the pendulum in place before transporting, ON/OFF switch in its „OFF“ position!
Inserting batteries
Open the battery compartment and insert batteries (2 x type AA) according to the symbols. Be sure to pay attention to polarity.

Horizontal and vertical levelling
Release the transport restraint, set the ON/OFF switch to „ON“. The laser
cross will appear. The laser lines can be switched individually with the
selection button.
The transport restraint must be released for horizontal and vertical
levelling. The LED (2) shows a permanent green light. The laser lines flash
and the LED (2) lights red as soon as the device is outside the automatic
levelling range of 5°. Position the device such that it is within the
levelling range. The LED (2) switches back to green and the laser lines stop
flashing (steady light).
Slope mode
Do not release the transport restraint, set the ON/OFF switch to „OFF“. Select and switch on the laser with the selection button. Sloping planes can now be measured. This mode cannot be used to perform horizontal or vertical levelling as the laser lines are no longer aligned automatically. The LED (2) lights are constantly red.
Hand receiver mode
Optional: Working with the laser receiver RX
Use an RX laser receiver (optional) to carry out levelling at great distances or when the laser lines are no longer visible. To work with a laser receiver, switch the line laser to hand-held receiver mode by keeping button 1 (handheld receiver mode on / off) pressed. The laser lines will now pulsate with high frequency, making the laser lines darker. The laser receiver can detect these pulsating laser lines. Observe the laser receiver‘s operating instructions for line lasers.
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 (LASER CROSS ON). The best calibration results are achieved if the device is mounted on a tripod.
-
Mark point A1 on the wall.
-
Turn the device through 180° and mark point A2.
You now have a horizontal reference between points A1 and A2. Performing the calibration check -
Position the device as near as possible to the wall at the height of point A1.
-
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- LASER LINER 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.
