Frequently Asked Questions - MasterPlane-Laser 3G Plus Laserliner

How to activate the anti-drift system (ADS)?

After turning on and leveling, press the tilt button (6). The tilt LED flashes rapidly to indicate that the ADS is active. The system continuously checks the laser position and turns it off if displaced to avoid measurement errors.

What to do if the laser lines flash?

Continuous flashing means the device is outside the self-leveling range (±3.5°). Reposition it on a flat surface. If the flashing is rapid for 30 seconds after turning on, it is the ADS adjustment phase, then the tilt LED flashes rapidly when activated.

How to use the tilt mode?

To work on inclined planes, do not release the transport lock. Slide the switch (2) to the right. Press and hold the selection button (7) to turn on the laser, then press again to select the lines. The laser no longer self-levels and the lines flash briefly every 5 seconds.

How to check the calibration?

Place the device between two walls at least 5 m apart. Mark point A1 on one wall. Rotate the device 180° and mark A2. Move the device close to the wall at the height of A1, rotate 180° again and mark A3. If the difference between A2 and A3 exceeds 0.2 mm/m, adjustment is necessary. Contact customer service.

What is the difference between green laser and a classic red laser?

The green laser (515 nm) is about 6 times brighter than a standard red laser (630-660 nm). Thanks to PowerGreen+ technology, it offers better visibility over long distances, on dark surfaces, and in daylight.

How to charge the battery?

Use only the supplied charger. Plug it into the device and the mains. The pack LED lights red during charging and turns blue when complete. Do not charge in a humid environment.

Can I use the laser with a receiver?

Yes, activate the manual receiver mode by pressing button 9. The lines become darker but pulse at high frequency to be detected by the GRX laser receiver (optional). The range can reach 60 m.

How to transport the laser safely?

Before transport, turn off the laser by sliding the switch (2) to the right to lock the pendulum. Use the integrated transport lock to prevent mechanical damage.

What does a permanently lit tilt LED mean?

This indicates that the ADS has detected a movement or loss of height reference. The laser turned off to avoid a measurement error. Press the tilt button once to reactivate the laser and continue.

How to clean and maintain the device?

Use a slightly damp cloth to clean the surfaces. Do not use chemicals, solvents, or abrasive products. Remove the battery for extended storage and keep the device in a dry place. Annual calibration is recommended.

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 3D laser projects one horizontal and two vertical laser circles, and is thus ideal for aligning objects precisely. The upper and lower laser crosses provide a plumb function for working simultaneously on floors and ceilings. In the event of external influences, the unit is switched off by the anti-drift system (ADS-Tilt) to prevent any incorrect measurements being taken. The 1/4" thread on the laser and the 5/8" thread on the clamp and wall bracket means that the device can be used on construction site and photography tripods. The laser has an integrated hand-held receiver mode for use with an (optional) laser receiver.

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 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.

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.
• 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 receivers over long distances.

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 external influences or if the laser loses its height reference, the laser switches off and the tilt LED lights up permanently. Press the tilt button to continue. 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

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.

When transporting, always switch off all lasers, secure pendulum and push the slide switch (2) to the right.

B Horizontal and vertical levelling

Release the transport restraint, push the slide switch (2) to the left. 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).

4 Slope mode

Do not release transport restraint, push slide switch (2) to the right.

Switch on the lasers by holding down the selection button (7).

Press it again to set the selection. Sloping planes and tilts can now be measured. In this mode, the laser lines will no longer align automatically, which will be indicated by the laser lines switching off briefly, roughly every five seconds.

!

The device can be switched off in any laser selection by holding down the button (7).

5 Hand receiver mode

Optional: Working with the laser receiver GRX

Use an 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 9 (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.

!

Due to the special optics required to generate a continuous 360^ laser line, the underlying technology may cause differences in brightness in different areas of the line. This may lead to different ranges in hand receiver mode.

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.

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.

Performing the calibration check

1. Position the device as near as possible to the wall at the height of point A1.

2. 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 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. Remove the battery before storing for longer periods. Store the device in a clean and dry place.

Calibration

The meter needs to be calibrated and tested on a regular basis to ensure it produces accurate measurement results. We recommend carrying out calibration once a year. Contact your authorised dealer or else the UMAREX-LASERLINER Service Department.
