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.

lock
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.

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.

6. The laser switches off and the tilt LED is lit continuously

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.

[1] 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.
– Charge the device‘s battery completely prior to use.
– Connect the power pack/charger to the mains power supply and the socket in the battery pack. Please only use the power pack/charger supplied. Using any other power pack/charger will invalidate the warranty.
– The LED on the battery pack lights up red while the battery is charging. When the LED changes to blue, charging is complete.

1. USB-C

The battery may only be charged with the battery charger provided and used only in this laser device. Any other use may cause injury or fire.

Make sure there are no conductive objects in the vicinity of the battery contacts. Short-circuiting of these contacts can cause burn injuries or fire.

Do not open the rechargeable battery. This could cause short-circuits.

[2] Power supply To insert the lithium-ion rechargeable battery

Open the battery compartment and insert the lithium-ion battery as illustrated.

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

[3] 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.

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
3. Position the device as near as possible to the wall at the height of point A1.
4. 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 ensureit produces accurate measurement results. We recommend carrying out calibration once a year. Contact your authorised dealer or else the UMAREX-LASERLINER Service Department.
