ENGLISH
1. Set up the laser in one corner of the fl oor and turn on the
forward vertical beam.
2. Mark the centre of the beam at three locations (A, B and C) on
the fl oor along the laser line. Mark B should be at the midpoint
of the laser line.
3. Move the laser to mark B and turn on both vertical beams.
4. Position the beam crossing precisely at mark B, with the
forward beam aligned with mark C.
5. Mark a location (D) along the side vertical beam at least 5 m
(18') away from the unit.
6. Rotate the laser over mark B so that the forward vertical beam
now passes through mark D.
7. Mark the location (E) where the side vertical beam passes by
mark A.
8. Measure the distance between marks A and E. If the
measurement is greater than the values shown in Table 4, the
laser must be serviced at an authorised service centre.
Troubleshooting
THE LASER DOES NOT TURN ON
• Make sure batteries are installed according to (+) and (–) on
the inside of the battery door.
• Make sure the batteries are in proper working condition. If in
doubt, try installing new batteries.
• Make sure that the battery contacts are clean and free of rust
or corrosion. Be sure to keep the laser level dry and use only
new, high-quality, name brand batteries to reduce the chance
of battery leakage.
• If the laser unit is heated above 50 °C (120 °F), the unit will
not turn on. If the laser has been stored in extremely hot
temperatures, allow it to cool. The laser level will not be
damaged by pressing the on/off button before cooling to its
proper operating temperature.
