- Apply specialty textured paper to designated areas, such as rooftops and decorative panels, following the manual's instructions for placement and adhesion.
- Integrate the mechanical gear-driven mechanism as instructed, ensuring propellers and structural details can move freely. Apply wax to moving parts if recommended by the manual to reduce friction.
- Install the hidden LED lighting system. Pay close attention to wiring and battery placement. Ensure all connections are secure.
Caution: Some users have reported that the supplied light string and battery box can become warm or lack an on/off switch. If you observe any unusual heat or prefer more control, consider replacing the lighting system with a safer, independently sourced alternative or omitting it entirely.

6. Maintenance and Care
Proper care will ensure the longevity and appearance of your Steam Castle Model.
- Cleaning: Dust the model regularly with a soft, dry cloth or a soft brush. Avoid using water, harsh chemicals, or abrasive cleaners, as they may damage the wood and paper components.
- Storage: Store the model in a dry environment away from direct sunlight and extreme temperature fluctuations. This prevents warping, fading, or damage to the materials.
- Handling: Handle the assembled model with care, especially delicate parts like balconies, spires, and propellers. Avoid dropping or applying excessive force.
- Battery Replacement: If the LED lights dim or stop working, replace the batteries in the lighting system. Refer to your assembly manual for the correct battery type and replacement procedure. Ensure proper polarity when inserting new batteries.
7. Troubleshooting
If you encounter any issues during assembly or operation, refer to the following troubleshooting tips:
- Pieces Not Fitting: If a wooden piece does not fit smoothly into its designated slot, do not force it. Gently sand the edges with the provided sandpaper or a fine-grit sandpaper until it fits without excessive pressure. Check the manual to ensure you are using the correct piece and orientation.
- LED Lights Not Working:
- Check if the batteries are correctly installed with the proper polarity and are not depleted. Replace batteries if necessary.
- Ensure all connections in the lighting system are secure and wires are not pinched or disconnected.
- Verify the mode switch is in an "On" position or cycle through the modes.
- Mechanical Parts Not Moving: Ensure no pieces are obstructing the gears or propellers. Check for any misaligned components that might be causing friction. Apply wax to moving parts if recommended and if they feel stiff.
- Damaged Pieces: If a piece is damaged during assembly or found to be defective upon opening, please contact FUNPOLA customer support for assistance.
