  • Page 3: Intended Use

    LAR 350 1. Intended Use The STABILA LAR-350 is an easy-to-use rotation laser for horizontal and vertical levelling, including obtaining plumb lines. The LAR-350 has a sealed enclosure (IP 65) for use on construction sites. It is self-levelling within a range of ± 5°.

  • Page 4: Safety Information

    Do not look into the direct or reflected beam. The STABILA laser goggles available for our laser devices do not constitute safety eyewear; their function is to improve the visibility of the laser beam.

  • Page 8: Using The Laser Unit

    LAR 350 6. Using the Laser Unit Place the laser unit in the appropriate working position (vertical or horizontal). To start the laser, press button (3). Holding this button for a longer period will switch the laser off again. Activating the self-levelling function causes the unit to level itself automatically.

  • Page 9: Tilt Function

    LAR 350 7. Tilt function The tilt function warns if any interference to the laser has occurred that may cause misalignment. This ensures that such interference does not go unnoticed. When the tilt function is active, the white LED (5) is lit stea- dily.

    LAR 350 8.1 Automatic Operation with Tilt Function This mode is always set directly after the unit is switched on (button 3). Other modes can be selected by pressing button (3) or button (4) or using the remote control unit. In ‘Automatic’...

  • Page 11: Automatic Operation With Relevelling

    LAR 350 8.2 Automatic Operation with Relevelling In some situations (e.g. when working on a shaking or vibrating surface), the tilt function can be a hindrance. With automatic relevelling, on the other hand, the unit is readjusted each time it is knocked out of alignment. Press button (3) x 2 = 1x switch on + 1x deactivate tilt function.

  • Page 12: Manual Operation With Tilt Function

    LAR 350 9.1 Manual Operation with Tilt Function In manual mode the laser plane is aligned by hand. Neither self-levelling nor relevelling are active. The unit does not level itself. If the tilt function is active, interferences (shocks, vibrations) that could misalign the unit from its exact original setting do not go unnoticed.

  • Page 13: Manual Operation Without Tilt Function

    LAR 350 9.2 Manual Operation without Tilt Function In manual operation without tilt function, neither automatic mode, the tilt function nor relevelling are active. In this mode the unit is aligned entirely by hand. The unit does not level itself. Place the laser unit in the appropriate working position (vertical or horizontal).

    LAR 350 12. Settings and Applications 13. Rotation Function/Rotation Speed The rotation function is set when the unit is switched on and can also be set at any time with button (25). In rotation mode the laser beam rotates. By holding down button (25) and simultaneously rotating the remote control unit the rotation speed can be infinitely adjusted up or down to 0 = point function.

  • Page 18: Line Function In Scan Mode

    LAR 350 14. Line Function in Scan Mode In scan mode the beam does not rotate. Instead, it moves to and fro rapidly between two points. The eye perceives this as a laser line. Button (24) switches the scan function on/off. When it is switched on, the scan line is always located opposite button (3) of the laser unit.

  • Page 19: Inclining The Laser Axes

    LAR 350 15. Inclining the Laser Axes (21) (17) Briefly pressing button (21) = laser x-axis or (22) = laser y-axis causes the rapidly flashing LEDs (blue or green) to indicate the corresponding laser axis. The laser axes can be adjusted independently through an inclination range of up to ±5°.

  • Page 20: Vertical Function

    LAR 350 16.1 Vertical Function To enable the LAR 350 to perform vertical levelling and mar- king tasks, it is placed on its side on the feet integrated into the body. Position the unit so that the wording ‘VERTICAL MODE THIS SIDE UP’ appears on the top. The ope- rator display is then also at the top.

  • Page 21: Rotating And Inclining The Laser Axes

    LAR 350 16.3 Rotating and Inclining the Laser Axes (21) Button (17) switches the laser axis rotation and inclination function on and off. Use buttons (21) and (22) to set the two laser axes. The corresponding LEDs flash during adjustment. (17) If only the laser y-axis is adjusted (button 22), the vertical alignment of the x-axis is retained.

  • Page 22: Positioning The Laser Beam

    LAR 350 17. Positioning the Laser Beam In certain applications it can be helpful to align the laser beam using only a single laser point. To do this, reduce the rotation speed to zero = point laser (button 25). --> Rotation Speed To rotate the laser point to the desired position, hold down (23) button (23).

  • Page 23: Displaying The Alignment Of The Laser Axes

    LAR 350 18. Displaying the Alignment of the (21) Laser Axes The blue and green LEDs indicate the respective axes if button (21) = laser x-axis or (22) = laser y-axis is briefly pressed. (21) --> ‘Inclining the Laser Axes’ -->...

  • Page 24: Section Mode

    LAR 350 20. Section Mode (23) 180° Here the rotating laser beam is limited to a particular sector. This prevents malfunctions occurring outside the actual working area through interference with other devices. Within the specified sector, all function modes of the rotation laser are available.

  • Page 26: Checking Accuracy

    LAR 350 22.1 Checking Accuracy The STABILA LAR 350 rotation laser has been designed for construction sites and has left our factory in a correctly adjusted condition. As with all precision instruments, you should regularly check the calibration accuracy of the unit.

  • Page 27: Horizontal Check

    LAR 350 22.2 Horizontal Check Checking the horizontal laser line level Be sure to adhere as closely as possible to the orientation of the unit as shown. 1. Place the LAR 350 on a horizontal surface or on a tripod at a distance of 5 or 10 m from a wall, with the operator panel towards the wall.

  • Page 28: Adjustment - Horizontal

    LAR 350 22.3 Adjustment - Horizontal If the tolerance level was exceeded in the horizontal check, the laser can be readjusted as follows. In each case the critical element is the distance that results from the measurement points taken from opposing positions, i.e. points 1+3 or 2+4. >...

  • Page 29: Vertical Check

    LAR 350 22.4 Vertical Check Checking the vertical plumb-line laser To perform the vertical check, two parallel wall surfaces are required with a separation S of at least 10 metres. 1. Position the rotation laser directly in front of one of S = 10 m / 50 ft the walls, A, on its side-mounted feet as for vertical levelling.

  • Page 30: Adjustment - Vertical

    LAR 350 22.5 Adjustment - Vertical If the tolerance level was exceeded in the vertical check, the laser can be readjusted as follows. When performing readjustments, ensure that the batteries are fully charged. > 5 sec Position the laser with the plumb axis towards the wall. Switch the laser off.
