7. Troubleshooting
If you encounter issues with your Hilti PM 2 laser level, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Laser lines are dim or not visible. | Low battery; dirty laser exit window; extremely bright ambient light. | Replace batteries; clean laser exit window; use in less bright conditions or with a laser receiver (if compatible). |
| Laser lines are flashing or device is beeping. | Device is out of its self-leveling range; low battery. | Adjust the device's position until it is within its self-leveling range; replace batteries. |
| Device does not turn on. | Batteries are dead or incorrectly inserted. | Check battery polarity; replace batteries. |
| Inaccurate measurements. | Device not self-leveling; device has been dropped or damaged. | Ensure device is self-leveled (no flashing lines); if accuracy issues persist after a drop, contact Hilti service for calibration. |
