6. Care and Maintenance
Proper care will ensure the longevity of your Steel Works construction set.
- Cleaning: Wipe metal parts with a dry or slightly damp cloth. Avoid harsh chemicals or abrasive cleaners.
- Storage: Store the assembled vehicle or disassembled parts in a dry environment to prevent rust. Keep small parts in a designated container to avoid loss.
- Inspections: Periodically check all nuts and bolts for tightness. Re-tighten any loose fasteners using the provided tools.
- Disassembly: If you wish to build a different model or store the set, carefully disassemble the vehicle by reversing the assembly steps.
7. Troubleshooting Common Issues
- Loose Parts: If parts become loose during play, identify the corresponding nut and bolt. Use the provided wrench to gently tighten the fastener until secure. Avoid overtightening.
- Difficulty Tightening Nuts: Some nuts may be in hard-to-reach areas. Try using the wrench at different angles or holding the bolt head steady while turning the nut. If a nut consistently loosens, consider adding a small washer if available, or ensure the bolt is fully engaged.
- Missing Parts: If you discover a missing part during assembly, carefully re-check the packaging and your workspace. If a part is genuinely missing, please contact customer support (see Section 9).
- Assembly Difficulties: If you encounter difficulty following the instructions, review the previous steps and diagrams in the physical instruction booklet. Ensure you are using the correct parts for each step.
