PRODUCT

Read the operating instructions and the enclosed brochure „Guarantee and additional notices“ completely. 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.

High-precision cross-line laser with 8 ultra bright laser lines and plumb laser

Homogeneous 360° laser line: The 4 horizontal laser diodes project a homogeneous laser line. This enables the device to be used like a rotary laser.
IR remote control allows the manual slope function for aligning inclines to be controlled. The relevant axes are visually displayed via LEDs.
A simple, precise plumb function is afforded by the additional plumb laser at the bottom and the laser cross at the top.
Out-Off-Level: is indicated by optical signals when the unit is outside its self-levelling range.
Automatic levelling range 3°, accuracy 1 mm / 10 m

General safety instructions

The device must only be used in accordance with its intended purpose and within the scope of the specifications.
Laser radiation!
Do not stare into the beam!
Class 2 laser
< 1 mW · 635/650 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.
Tampering with (making changes to) the laser device is not permitted.
This device is not a toy – keep out of the reach of children.

Special product features
Electronic vials and positioning motors controlled by tempera-turestable sensors for automatic alignment of devices. The device is brought into initial position and aligns itself autonomously. This function is automatically enabled when the sensor auto-matic is switched on. This easily enables the horizontal or vertical levelling at a required hight, for instance in connection with a crank tripod or wall mount. Also, the laser can be used on vibrating surfaces and in windy conditions.
Transport LOCK : The device is protected by a special motor brake during transport.
Laser diodes of the highest performance class produce extremely bright laser lines. They remain visible even on surfaces at great distances or on dark surfaces as well as under bright ambient light conditions. RX-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.

Use of lithium-ion rechargeable battery
Before using the laser for the first time, insert the battery in the device and fully charge (at least 6 hours). Connect the battery charger to charge the battery. The LED of the battery pack lights red while the battery is charging. When the LED changes to green, charging is complete. When the laser lines blink slowly, the battery is low. In that case, recharge the battery. The rechargeable battery can either be charged when it is not inserted in the device or when the device is in use.

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.

Observing the correct polarity.

Positioning laser lines
The top section of the laser unit can be turned on the plinth to align the lasers approximately. Precise positioning can then be done with the Vernier adjustment (4). The adjustable feet (7) allow the device to be positioned on sloping surfaces. The freely rotatable horizontal circle (3) makes it easy to turn the device to the required angle. Simply set the scale to zero, then rotate the device to the angle you want.

Horizontal and vertical levelling
Switch the laser device on. The automatic sensor is now active and will level the laser device automatically. As soon as device-levelling is completed and the auto LED illuminates continuously, horizontal or vertical object levelling can be carried out. Maximum accuracy is attained when device-levelling is completed. Lasers can be switched on and off individually with the H or V1/2 buttons (press buttons briefly).

If the unit is placed at an excessive angle (out of its 3° range), the lasers will blink. Align the device using the adjustable feet (7) or place on a more level surface.

Slope function up to max. 3°
Activation of the slope function deactivates the automatic sensor. In addition, press the auto/man button until the LEDs of the x-axis (15) light up. Motor- driven adjustment of the slope can now be carried out. Hold the plus or minus buttons down continuously to adjust slope. When the lasers blink, the maximum slope range has been reached. The X/Y button (pressed briefly) is used to switch between axes. Refer to the illustrations below.

For the slope function, laser lines are no longer aligned to the horizontal or vertical plane. This is a specific peculiarity of adjusted laser lines. To reinstate horizontal or vertical levelling, deactivate the slope function. To do so, switch the device off and back on or keep the auto/man button pressed until the laser lines move automatically.

Steeper slopes can be set using the angle plate, which is available as an optional extra (product ref. 080.75). To this end you need to use a crank tripod, such as the 300 cm professional crank tripod, product ref. 080.34. Refer to the illustrations below.
TIP:
Set the angle plate to the zero position and allow the device to align itself automatically. Then press the auto/man button to switch the automatic sensor off. Finally, incline the device to the angle you require.

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 into hand receiver mode with the Hand receiver mode button (11). The laser lines will now pulsate with high frequency, making the laser lines darker. The laser receiver RX can detect these pulsating laser lines. Hand receiver mode can be used for horizontal or vertical levelling as well as for slope functions.

Follow the operating instructions of the corresponding laser receiver.

EU directives and disposal

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.

The automatic sensor must be active in order to check calibration and to complete device-levelling. See Section „Horizontal and vertical levelling“ about this.

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 A2and A3 are more than 1mm/10m 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 ± 0.5 mm.
Checking the horizontal line:
Laserliner PowerCross-Laser 8 S Line Laser Self-Levelling Range
24 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 ± 0.5 mm. Repeat the process by turning the laser to the left.
