- Self-Leveling Function: Automatically levels within ±3° for quick and accurate setup.
- Locking Pendulum: Protects the laser emitter during transport and allows for manual mode operation (tilt function).
- Working Range: Up to 30 meters (100 feet), extendable to 50 meters with a detector.
- High Accuracy: Provides an accuracy of ±0.2mm/m.
- Durable Design: IP65 rating for dust and water resistance.
- Power: Equipped with a 3.7V 3.0Ah Lithium battery.
- Mounting: Features a 1/4" thread for tripod mounting and includes a magnetic wall bracket.
5. Setup
- Charging the Battery: Before first use, fully charge the 3.6V 3.0Ah Lithium battery using the provided fast charge adapter. The charging indicator will show the charging status.
- Mounting the Device:
- On a Tripod: Screw the laser level onto the 1/4" thread of the 360° Rotating Fine Tuning Base or a compatible tripod. Ensure it is securely fastened.
- Using the Magnetic Wall Bracket: Attach the magnetic wall bracket to a metallic surface. The laser level can then be mounted onto the bracket.
- Positioning: Place the laser level on a stable, level surface or mount it securely. For optimal performance, ensure the device is within its self-leveling range (±3°).
6. Operating Instructions
- Power On/Off: Slide the locking pendulum switch to the unlocked position to power on the device. The laser lines will activate. Slide it back to the locked position to power off.
- Self-Leveling Mode: When the pendulum is unlocked, the device will automatically self-level. If the device is outside its ±3° self-leveling range, the laser lines will flash rapidly to indicate it cannot self-level. Adjust the device's position until the lines stop flashing.
- Manual Mode (Tilt Function): To use the device for projecting non-level lines (e.g., for stairs or angled installations):
- With the device powered on (pendulum unlocked), press and hold the "H" (Horizontal) or "V" (Vertical) button for 3 seconds. The laser lines will stop flashing, indicating manual mode is active.
- In manual mode, the self-leveling function is deactivated, and the laser lines can be projected at any angle.
- Press the "H" or "V" button again to switch between horizontal and vertical lines, or to activate all lines.
- Line Selection: Press the "H" button to cycle through horizontal lines and the "V" button to cycle through vertical lines.
- Using the Detector (Optional): For outdoor use or when the laser lines are difficult to see, an optional laser detector can extend the working range up to 50 meters.
7. Maintenance
- Cleaning: Use a soft, damp cloth to clean the device. Do not use abrasive cleaners or solvents.
- Storage: Store the laser level in its Oxford Portable Bag in a dry, cool place when not in use. Ensure the pendulum is locked to protect the internal components.
- Battery Care:
- Charge the battery regularly, even if not in use, to maintain its lifespan.
- Do not expose the battery to extreme temperatures.
- Calibration: If you suspect the laser level is out of calibration, refer to a qualified service technician.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Laser lines are flashing rapidly. | Device is outside its self-leveling range (±3°). | Adjust the device's position until it is within the self-leveling range. |
| No laser lines or dim lines. | Low battery or device is off. | Charge the battery or ensure the device is powered on (pendulum unlocked). |
| Laser lines are not level in self-leveling mode. | Device is on an unstable surface or requires calibration. | Place on a stable surface. If problem persists, contact customer support for calibration. |
| Device does not turn on. | Battery is completely drained or not inserted correctly. Pendulum is locked. | Charge the battery. Ensure battery is properly inserted. Unlock the pendulum. |
