metabo BLL 2-15 Floor Line Laser

Operating instructions

The Metabo BLL 2-15 is an easy-to-use floor line laser. It enables rapid yet precise alignment of elements (especially tiles) on the floor. The laser lines projected vertically onto the floor at an angle of 90° make sure your work is totally precise. The pulsed laser line enables working over larger distances using a special laser line receiver. Read the User Manual along with the illustrated portion. Follow the general instructions on the handling, care and maintenance of the instrument. Observe the safety instructions on laser beams.

Main components

1. On/off button
2. LEDs for displaying
   • LED green: Operating mode ON or READY
   • LED red: battery voltage
3. Outlet openings for laser lines
4. Vial
5. Battery compartment cover

Before initial start-up :
The warning notice in your language must be clearly affixed on the laser instrument at the position indicated. The appropriate stickers are enclosed. This sticker with the warning notice written in the usual language must be affixed here in place of the English text! Batteries must be inserted -> changing batteries.

Main applications

Operating modes

The BLL 2-15 can be used in 2 operating modes:

1. As an easy-setup floor line laser for layout work
2. As tile laser combined with special base enabling exact positioning for edge-precise alignment of tile layouts.

Commissioning
The instrument is switched on with the on/off switch (1). Laser lines appear aft er switching on. An angle of 90° is thus projected on the floor. The intersection of the laser lines enables easy alignment and measuring. The BLL 2-15 can be set up very close in a corner. The locating edges for the base correspond to the position of the laser lines. Measuring tools and, if required, a target plate make a fully accurate alignment to the surroundings (corner, wall etc.) possible. The BLL 2-15 can therefore be aligned to a reference plane.

Operating mode as floor line laser
The base is positioned with its locating teeth upwards below the laser device. The BLL 2-15 is easily set up and aligned at a mark.
Operating mode as tile laser
The interchangeable base enables exact positioning at the edges of tiles/slabs. The BLL 2-15 can be positioned to the side of a tile / within several tiles. Changing over the base with the locating teeth downwards allows the BLL 2-15 to be positioned on a tile as well. The laser lines are therefore aligned accurately with the tile edges while projecting extension lines precisely onto the floor.
Checking the calibration
The floor line laser BLL 2-15 is designed for use on construction sites and left our factory perfectly adjusted. As with any precision instrument, however, its calibration must be regularly checked. The unit should be checked before starting any new tasks, particularly when the unit has been exposed to strong vibrations.

Checking the angular accuracy to 90° :

The check is carried out using the target plate ZP!

1. Select a measuring section with a minimum length of 10 m / 32‘10“. Mark point A on the floor at one end of the section.
2. Align the intersection of the laser lines over point A.
3. Mark point B on the floor roughly in the middle of the section and point C at the end.
4. Move the BLL 2-15 to point B and realign laser line 1 ( L1) on point „C“.
5. Mark position „D“ of the right-angle laser line 2 (L2) on the floor.
6. Rotate the BLL 2-15 through 90° so that laser line 1 (L1) is aligned with point „D“.
7. Mark the position E of the right-angled laser line 2 (L2) at the shortest distance to point A on the floor.
8. Measure the distance between points „A“ and „E“.

Note:
For a precise check, the distances from A to B, B to C, and B to D should be approximately the same.

Replacing the batteries
Slide the battery cover (4) in the direction of the arrow and insert new batteries in accordance with the symbols in the battery compartment. Suitable batteries can also be used.
