en Operating instructions The STABILA-LA90L / LA 180L instruments are easy-to-use multi-line lasers. They are self-levelling within the range of ± 5° and enable the user to level quickly and precisely. The vertically and horizontally projected laser lines provide exact alignment / working. The LA 180L has a motorised fine adjustment facility for 90° angle positioning.
NB: In Class 2 laser equipment, your eyes are normally protected from accidental, short-term exposure P 0 < 1 mW to the laser beam by the lid-closing reflex and/or λ = 630 - 660 nm the reflex reaction to turn one‘s head. If a laser beam should Beam divergence < 180° Beam divergence <1.5mrad encounter your eye, you should consciously close your IEC 60825-1:2007 eyes and immediately move your head out of the beam. Do not look directly into the direct or reflected beam.
Setting the type of line: Button (1c): switches the horizontal laser line on/off. The horizontal laser line can only be switched off if at least one vertical laser line is switched on. (1c) The horizontal laser line can be used, for example, for levelling over long distances or for the horizontal alignment of building components and members. Button (1d): different vertical laser lines can be switched on / off in succession. The plumb-line point is also switched on / off at the same time.
Fine adjustment Using the adjusting screw, the upper part can be rotated through ± 5° around its vertical axis, enabling a vertical laser line to be aligned precisely with a reference line. With the LA-180L, the fine adjustment procedure can also be undertaken using the receiver. F Operating mode without levelling function. Button (1b): the levelling function is switched off. In this mode the laser lines flashes.

3. Checking the angular accuracy of the vertical lines: checking the 90° angle of the vertical lines. 2 LA-90L, LA-180L: checking 90° angle I I II 1 3 1. Choose a room which is at least 10 m ( 32‘10“ ) long. At one end mark point „A“ on the floor. H1 2. Align the laser with its plumb-line beam directly over point „A“. Ensure that laser line 1 can be seen at the opposite end of the room. 3. At about the middle of the room mark point „B“ on the floor. 4.
Horizontal checking G1 G2 1. Horizontal checking - Line level Two parallel wall surfaces at least 5m /16‘5“ apart are required for the horizontal check. (1a) 2. Switch the unit on - button (1a) (1c) (1d) G3 G4 G5 1. Place the LA90L / LA180L on a smooth surface or on a tripod as close as possible to wall A and with the front side pointing towards the wall 3. Switch on the horizontal laser line - button (1c) 4. Switch on the vertical laser lines - button (1d) 5.
Only LA-180L: Registering the REC 410 Line RF receiver with the laser transmitter : 1. Switch off the laser transmitter (button 1a) 2. Press and hold down buttons (1c) and (1d). 3. Switch the unit on - button (1a) 4. The laser transmitter is in registration mode. The LEDs (red and green) flash alternately. 5. Press the button “automatic precision alignment“ (d) on the REC 410 Line RF receiver. 6.

Care and maintenance • Dirty lens glass on the beam emitter detracts from the quality of the beam. It should be cleaned with a soft cloth. • Clean the laser unit with a damp cloth. Do not spray or immerse the unit! Do not use solvents or thinners! The LA90L / LA180L multi-line laser must be handled carefully, in the same way as any precision optical instrument.
