Leveling Modes
The Bosch GRL 250 HVCK offers three leveling modes:

- Single Slope: Allows you to set a custom slope between -4° and +4° for applications like creating a sloped surface for drainage.
Adjusting the Laser Level
To adjust the laser level, use the manual mode knob to fine-tune the laser line within ±4 degrees of the horizontal or vertical plane. This is particularly useful when working in situations where the self-leveling feature cannot be used.
Troubleshooting Common Issues
If your Bosch GRL 250 HVCK is not working as expected, consult the following troubleshooting tips:
| Issue | Solution |
|---|---|
| Laser line is not visible or faint. | Ensure the laser level is within its visible range (up to 50 feet in diameter). Check for obstructions and adjust the laser level's position or angle. If the issue persists, clean the laser window with a soft, damp cloth. |
| Laser level does not self-level or remains on even after turning off. | Check if the laser level is within the self-leveling range (±4 degrees). If not, adjust its position or use the manual mode knob to fine-tune the laser line. If the issue persists, recalibrate the laser level following the instructions in the manual. |
