Top 3 Frequently Asked Questions

1. Is this laser bright enough for outdoor use?

The red laser is best suited for indoor use. For bright outdoor conditions, a green laser model or using a laser receiver (sold separately) is recommended.

2. Can the battery be replaced with a rechargeable battery?

Yes, the tool is Dual Power Source compatible. It runs on the included AA batteries, but can also be powered by the optional Bosch 3.7V Li-Ion battery pack (BA 3.7V 1.0Ah A Professional).

3. How do I lock the pendulum for sloped lines?

Simply switch the laser off when tilting the unit outside of its self-levelling range. The lines will blink to indicate it is in manual/slope mode, allowing you to set non-level lines.
