PocketCross-Laser 2G Cross Line Laser Self Levelling
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.
Intended use
This cross-line laser projects a clearly visible green laser cross and is suitable for aligning horizontals, verticals and inclinations. Optical signals indicate when the unit is outside its self-levelling range. The product has an integral hand-held receiver mode and a 1/4″ tripod connection.
General safety instructions
- The device must only be used in accordance with its intendedpurpose 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 nm EN
60825-1:2014/AC:2017
- 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.
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. -
The measuring accuracy may be affected when working close to high voltages or high electromagnetic alternating fields.
Special product features
| Automatic alignment of the device with a magnetically dampened pendulum
system. The device is brought into initial position and aligns itself
autonomously.
---|---
| Transport LOCK: The device is protected with a pendelum lock during
transport.
| GRX-READY technology enables line lasers to be used even in unfavourable
light conditions.The laser lines pulsate at
a high frequency and this can be picked up by special laser receiversover long
distances.
Green laser technology
| Approx. 6 times brighter than a typical red laser with 630 – 660 nm.
---|---
| Devices with the PowerGreen+ technology have very bright, green high-
performance diodes which provide outstanding
visibility of the laser lines at great distances, on dark surfaces and in
bright ambient lighting conditions.

Use of lithium-ion rechargeable battery
– Use the power supply/charger unit only in closed rooms; do not expose to moisture or rain otherwise risk of electric shock.
– Ensure the device’s battery is fully charged before using the device.
– Connect the power pack/charger to the mains power supply and the socket on the device‘s battery pack. Please only use the power pack/ charger supplied. Using any other power pack/charger will invalidate the warranty.
– The LED display flashes while the device is charging. Charging is complete when the LEDs are continuously lit. The device has a replaceable battery. Contact your distributor or the UMAREX-LASERLINER service department. -
Horizontal and vertical levelling
Release the transport restraint, push the slide switch (2) to the right.
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 laser lines flash as soon
as the device is outside the automatic levelling range of 3.5°. Position the
device such that it is within the levelling range. The laser lines stop
flashing (steady light). -
Slope mode
Do not release transport restraint, push slide switch (2) to the left.
Select the laser with the selector button (6). Sloping planes and tilts can now be measured. In this mode, the laser lines no longer align automatically.
-
Hand receiver mode
Optional: Working with the laser receiver GRX
Use an GRX 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 pressing button 7 (handheld receiver mode on / off). 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 m 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 0.3 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 ± 2 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.
Regularly check the calibration before use, after transport and after extended
periods of storage.
Information on maintenance and care
Clean all components with a damp cloth and do not use cleaning agents,
scouring agents and solvents. Store the device in a clean and dry place.
Calibration
The meter needs to be calibrated and tested on a regular basis to ensureit
produces accurate measurement results. We recommend carrying out calibration
once a year. Contact your authorised dealer or else the UMAREX-LASERLINER
Service Department.
