5. Setup
5.1 Battery Installation
- Locate the battery compartment on the laser level.
- Insert the provided 12.6V/2600mAh Li-ion battery, ensuring correct polarity.
- Close the battery compartment securely.
- To charge the battery, connect the Type-C cord to the laser level and the power adapter, then plug into a power outlet.
5.2 Mounting the Laser Level
The W03CG-3D offers versatile mounting options:
- Magnetic Bracket: Attach the magnetic bracket to metal surfaces for wall applications.
- Tripod/Pole Mount: Use the 1/4"-20 or 5/8"-11 mounting threads to secure the laser level to a standard tripod or pole mount.
6. Operating Instructions
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 the 'OFF' position.
6.2 Operating Modes

- Self-Leveling Mode: When the main switch is in the 'ON' position, the laser level automatically enters self-leveling mode. The device will self-level within ±3°. If the tilt exceeds this range, the laser lines will flash rapidly to indicate an out-of-level condition.
- Manual Mode: To activate manual mode, slide the main switch to the 'OFF' position. This allows the laser level to be placed at any angle for sloped applications without self-leveling.
- Pulse Mode: Activate pulse mode for use with a laser receiver in bright outdoor conditions or for extending the working range up to 200 feet. The laser receiver is sold separately.
6.3 Line Switching and Brightness Adjustment

Use the touch panel buttons or the remote control/app to switch between the 360° horizontal and vertical laser lines. The laser brightness can also be adjusted to suit ambient light conditions.
6.4 Electric Rotating Base Operation


The electric rotating base can be controlled via the remote control or the Bluetooth app. It offers three speeds for precise adjustment:
- Low Speed: 9.1mm/s for fine adjustments.
- Medium Speed: 48mm/s for moderate adjustments.
- High Speed: 240mm/s for quick positioning.
6.5 Bluetooth App and Remote Control
Download the Huepar app to your smartphone. Pair the device via Bluetooth to access advanced controls, including mode selection, line switching, brightness adjustment, and electric rotating base speed control. The included remote control provides similar functionality.
7. LCD Display Indicators

The backlit LCD screen provides real-time information:
- Laser Lines in Use: Indicates which horizontal and vertical lines are active.
- Tilt Angle: Displays the current tilt angle of the device.
- Battery Power Condition: Shows the remaining battery charge.
- Pulse Mode Indicator: Confirms if pulse mode is active.
- Self-Leveling Mode Indicator: Shows if the device is in self-leveling mode.
- Manual Mode Indicator: Shows if the device is in manual mode.
- Rotation Speed: Displays the current speed setting of the electric rotating base.
8. Maintenance

9. Troubleshooting
If you encounter issues with your Huepar W03CG-3D laser level, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Laser lines are flashing rapidly. | Device is out of self-leveling range (±3°). | Place the laser level on a more level surface or adjust its position until the lines stabilize. |
| No laser lines appear. | Battery is low or not installed correctly. Device is off. | Check battery charge and installation. Ensure the main switch is in the 'ON' position. |
| Remote control or Bluetooth app not working. | Out of range. Battery in remote is low. Bluetooth not paired. | Ensure you are within 65 feet. Replace remote battery. Re-pair Bluetooth connection. |
| Laser lines are dim. | Brightness setting is low. Bright ambient light. | Adjust laser brightness via touch panel or app. Activate pulse mode and use a laser receiver for outdoor/bright conditions. |
