  • The laser lines are flashing. This is usually caused by low batteries or the laser being out of level. To fix the flashing laser lines, first check the batteries to make sure they are inserted correctly and have enough power. If the batteries are good, then the laser may be out of level. To check the laser level, place it on a flat surface and use the built-in bubble level to make sure it is level. If the laser is not level, adjust the feet until it is level.
  • The laser is not turning on. This may be caused by a dead battery or a faulty switch. To fix the laser not turning on, first check the batteries to make sure they are inserted correctly and have enough power. If the batteries are good, then the switch may be faulty. To test the switch, try turning the laser on and off several times. If the switch is faulty, you will need to replace it.
  • The laser is not accurate. This may be caused by a loose laser module or a misalignment of the laser beams. To fix the inaccurate laser, first check the laser module to make sure it is tight. If the laser module is tight, then the laser beams may be misaligned. To realign the laser beams, follow the instructions in the user manual.

If you are having problems with your Bosch GLL40-20G that are not listed above, you should contact Bosch customer service for assistance.

Here are some additional tips for troubleshooting common problems with the Bosch GLL40-20G:
