6. Operation

6.1 Power On/Off

To power on the device, slide the main switch to the 'ON' position. To power off, slide the switch to 'OFF'.

6.2 Self-Leveling Mode

When powered on, the device defaults to self-leveling mode. Place the laser level on a stable surface. The internal pendulum will automatically level the laser lines within ±3°. If the device is tilted beyond this range, the laser lines will flash and an audible alarm will sound, indicating that the device is out of level. Adjust the position of the device until the lines stabilize and the alarm stops.

6.3 Manual Mode (Tilt Mode)

To activate manual mode, press and hold the 'OD' (OUT) button on the control panel or remote control for approximately 3 seconds. In manual mode, the pendulum is locked, allowing you to project laser lines at any desired angle. The laser lines will not flash, and no alarm will sound, even if the device is tilted. Press and hold the 'OD' button again to return to self-leveling mode.

6.4 Switching Laser Lines and Brightness

Use the 'H' (Horizontal) and 'V' (Vertical) buttons on the control panel or remote control to switch between different laser line combinations:

• Press 'H' to activate/deactivate horizontal lines.
• Press 'V' to activate/deactivate vertical lines.
• The 'OD' button can also be used for brightness adjustment in some modes.

6.5 Remote Control Usage

The remote control allows for convenient operation from a distance, especially useful in large work areas or when the device is mounted in hard-to-reach places.

• Use the 'H' button to control horizontal laser lines (H1 and H2).
• Use the 'V' button to control vertical laser lines (V1 and V2).
• The 'OD' button switches between automatic leveling and manual mode, and can also adjust brightness.

7. Maintenance

Proper maintenance ensures the longevity and accuracy of your laser level.

• Cleaning: Use a soft, damp cloth to clean the device. Do not use abrasive cleaners or solvents. Keep the laser windows clean for optimal beam clarity.
• Storage: Store the laser level in its carrying case in a dry, cool place, away from direct sunlight and extreme temperatures. Remove batteries if storing for extended periods.
• Battery Care: Recharge batteries regularly, even if not in use, to maintain their lifespan. Avoid fully discharging batteries.
• Laser Windows: The laser windows can be removed and replaced with a screwdriver if necessary for cleaning or service.

8. Troubleshooting

If you encounter issues with your FELLAT laser level, refer to the following common problems and solutions:

• Laser lines are flashing and alarm is sounding: The device is in self-leveling mode and is tilted beyond its ±3° self-leveling range. Adjust the device's position until it is within range.
• Laser lines are dim or not visible: Check battery charge. Ensure laser windows are clean. In bright outdoor conditions, use the laser target plate to enhance visibility.
• Device does not power on: Ensure batteries are correctly installed and fully charged.
• Remote control not working: Check the remote control's battery. Ensure there are no obstructions between the remote and the laser level.

If problems persist, contact customer support for assistance.
