5. Operating and Display
Once assembled, the COBI tank models are designed for display and gentle play.
- Display: Place your completed models on a stable, flat surface away from direct sunlight and extreme temperatures to preserve their colors and structural integrity.
- Gentle Play: The models are robust enough for light handling and imaginative play. Avoid excessive force, dropping, or throwing the models, as this may cause parts to detach or break.
- Movable Parts: Some models may feature movable turrets, cannons, or tracks. Operate these parts gently to prevent damage.

6. Maintenance
To ensure the longevity and appearance of your COBI models, follow these simple maintenance guidelines:
- Cleaning: Dust the models regularly with a soft, dry cloth or a soft brush. For more stubborn dirt, a slightly damp cloth can be used, but avoid excessive moisture.
- Storage: If disassembling for storage, keep all blocks in a sealed container to prevent loss and protect them from dust and dirt.
- Avoid Chemicals: Do not use harsh chemicals, abrasive cleaners, or solvents, as these can damage the plastic and printed details.
- Temperature: Avoid exposing the models to extreme temperatures or prolonged direct sunlight, which can cause discoloration or warping of the plastic.
7. Troubleshooting
Should you encounter any issues during the assembly or use of your COBI set, consider the following:
- Missing Pieces: Double-check all packaging materials and the assembly area. If a piece is genuinely missing, contact COBI customer support (see Section 9).
- Difficulty Assembling: Review the instruction booklet carefully. Ensure you are using the correct pieces and following the steps in the correct order. Sometimes, a piece may require a firm push to connect properly.
- Model Instability: Ensure all connections are secure. If a model feels unstable, retrace the last few steps of assembly to confirm all blocks are correctly attached.
