Instruction Manual
Completely read through the operating instructions, the “Warranty and Additional Information” booklet as well as the latest information under the internet link at the end of these instructions. Follow the instructions they contain. This document must be kept in a safe place and if the laser device is passed on, this document must be passed on with it.
Function /Application
Green cross-line laser for vertical and horizontal alignment
– The slope-mode feature is an extra that permits gradients to be laid out.
– Additional plumb laser at top and bottom
– Individually selectable laser lines and plumb laser
– Out-Of-Level: is indicated by optical signals when the unit is outside its
self-leveling range.
– With the magnetic clamp and wall bracket the device can be used as a
standalone unit, in a combination as well as in horizontal and vertical
positions.
– Ideal for mounting horizontally and vertically on drywall construction
profiles.
– Automatic leveling range 3°, accuracy ± 0,2 mm / m
General safety instructions
– The device must only be used in accordance with its intended purpose and
within the scope of the specifications.
– The measuring tools and accessories are not toys. Keep out of reach of
children.
– Modifications or changes to the device are not permitted, this will
otherwise invalidate the approval and safety specifications.
– Do not expose the device to mechanical stress, extreme temperatures,
moisture or significant vibration.
– The device must no longer be used if one or more of its functions fail or
the battery charge is weak.
Safety instructions
Using class 2 lasers
Laser radiation! Do not stare into the beam! Class 2 laser < 1 mW · 515 / 635 nm EN 60825-1:2014
– 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.
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
Automatic alignment of the device with a magnetically dampened pendulum
system. The device is brought into the initial position and aligns itself
autonomously.
Transport LOCK: The device is protected with a pendulum lock during transport.
GRX-READY technology enables line lasers to be used even in unfavorable light
conditions. The laser lines pulsate at a high frequency and this can be picked
up by special laser receivers over long distances.
Green laser technology
Laser modules in DLD design stand for high line quality as well as a clean
and clear and therefore easily visible line image. 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. This makes 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 unfavorable conditions.
Approx. 6 times brighter than a typical red laser with 630 – 660 nm

Inserting the batteries
Open the battery compartment (3) and insert the batteries in accordance with
the installation symbols, ensuring the correct polarity.

When transporting always switch off all lasers, secure the pendulum and set
the slide switch to “OFF”!

Horizontal and vertical leveling
Release the transport restraint, and set slide switch (2) to “ON”. The laser
cross, the plumb laser and the reference beam appear. The lasers can be
switched individually using the selection button.
The transport restraint must be released for horizontal and vertical leveling.
The selected lasers flash when the device is outside the automatic leveling
range of 3°. Position the device such that it is within the leveling range.
The selected lasers shine continuously.
Slope mode
Do not release the transport restraint, set slide switch (2) to the mid- position and select the lasers with the selector switch. Sloping planes and tilts can now be measured. In this ode, the laser lines no longer align automatically. This is indicated when the selected lasers flash.
Hand receiver mode Optional: Working with the laser receiver GRX
Use a GRX laser receiver (optional) to carry out leveling 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 6 (hand-
held 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.
Follow the operating instructions of the corresponding laser receiver.
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 meters
apart. Do this by turning the nit on, thus releasing the transport restraint
(cross laser on). Please use 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 ± 0.2 mm / m apart, an adjustment is necessary.
Contact your authorized 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, makingsure 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.
