6. Operating Your Model
This building block set creates a static or push-along model. It is not motorized and does not require batteries.
- Display: The assembled chassis can be used as a display model.
- Play: Gently push the model on smooth surfaces. Avoid rough handling or dropping to prevent parts from detaching.
- Integration: As a MOC (My Own Creation) component, this chassis can be integrated into larger building block projects or custom vehicle designs.
7. Care and Maintenance
- Cleaning: To clean the blocks, wipe them gently with a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, followed by immediate drying. Do not use harsh chemicals or abrasive cleaners.
- Storage: Store the assembled model or individual blocks in a cool, dry place away from direct sunlight to prevent material degradation or discoloration.
- Disassembly: If disassembling the model, do so carefully to avoid stressing or breaking the plastic connectors.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Parts do not fit together | Incorrect orientation or incompatible pieces. | Refer to the assembly images and ensure correct piece selection and orientation. Apply gentle, even pressure. |
| Model is unstable or wobbly | Loose connections or missing pieces. | Double-check all connections to ensure they are firmly pressed together. Verify all required pieces are used. |
| Wheels do not spin freely | Axle or wheel components are too tight or misaligned. | Ensure axles are inserted correctly and not overly constrained. Re-seat wheels if necessary. |
| Missing pieces | Manufacturing error or lost during unpacking. | Carefully check packaging and assembly area. If still missing, contact customer support with details of the missing part. |
