7. Maintenance
- Cleaning: Wipe the figure with a soft, dry cloth to remove dust. Avoid using harsh chemicals or abrasive materials, which can damage the paint and plastic.
- Storage: Store the figure away from direct sunlight and extreme temperatures to prevent discoloration or warping of plastic components.
- Joint Care: If joints become stiff, gently work them back and forth. Do not force movement, as this can cause breakage.
8. Troubleshooting
- Difficulty Transforming: If you encounter difficulty during transformation, re-examine the instruction manual's diagrams for the specific step. Ensure all previous steps are correctly completed. Do not apply excessive force.
- Loose Joints: Over time, some joints may become slightly loose. This is typical with articulated figures. For minor looseness, clear nail polish or a similar thin coating can be applied to the joint peg and allowed to dry to increase friction.
- Missing or Broken Parts: In case of missing or broken parts upon purchase, please contact the retailer or manufacturer's customer support.
