3. Operating Instructions
The LG01 Link Pack features an electric drive system and a touch switch for controlling power and lighting effects. The unit is powered via USB-C, utilizing the motor from the LGC01 model.
3.1 Touch Switch Control
- Tap once: The models will power on, and the blue breathing light will illuminate with a flowing, gradual effect.
- Tap again: The blue light will switch to a constant illumination mode.
- Long press: The models will power off, and the light will extinguish.
3.2 Functionality
- The orbital transmission shaft drives the gears of both connected models, ensuring synchronized movement.
- The gear chain replaces manual operation, transmitting rotational force to the internal structure through the drive shaft.
- Additional track connections within the link pack allow marbles to cycle infinitely between the connected models.

4. Maintenance
To ensure the longevity and smooth operation of your ROBOTIME LG01 Marble Run Link Pack, follow these maintenance guidelines:
- Cleaning: Dust the wooden components regularly with a soft, dry cloth. Avoid using abrasive cleaners or excessive moisture, which can damage the wood.
- Storage: Store the assembled model in a dry environment, away from direct sunlight and extreme temperature fluctuations, to prevent warping or damage to the wood.
- Component Check: Periodically inspect all connections and moving parts to ensure they are secure and free from obstruction.
5. Troubleshooting
If you encounter issues with your LG01 Marble Run Link Pack, consider the following troubleshooting steps:
- Parts Not Fitting: Double-check the instruction manual to ensure you are using the correct pieces and orienting them as shown. Wooden pieces may require gentle pressure to fit snugly. Do not force pieces, as this can cause breakage.
- Mechanism Not Moving Smoothly: Verify that all gears, shafts, and belts are correctly installed and aligned. Ensure no foreign objects or excess glue are obstructing movement. Check that the power source (USB-C) is properly connected and providing sufficient power.
- Light Not Functioning: Confirm the blue breathing light module is correctly connected to the power source and that the touch switch is being operated as described in Section 3.1.
- Marbles Not Cycling: Inspect the tracks for any misalignments or obstructions that might prevent marbles from moving freely. Ensure the connection points to the LGA01 and LGC01 models are seamless.
If problems persist after attempting these steps, please refer to the Support section for further assistance.
