Assembly Instructions
Your Bandai Spirits model kit is designed for easy assembly without the need for glue. All parts are engineered for a precise snap-fit construction, ensuring a secure and stable model once completed.
Key Features for Assembly
- No Glue Required: All components are designed to fit together securely without adhesive, making assembly straightforward.
- Easy Color Recreation: Innovative runner technology allows for multiple colors on a single parts frame, simplifying color accuracy and reducing the need for painting.
Step-by-Step Assembly (General Guidelines)
While a detailed graphical manual is included with your kit, these general steps outline the assembly process:
- Unpack Components: Carefully remove all runners (parts frames) from the box. Organize them by their letter designations.
- Identify Parts: Refer to the included graphical instructions to identify each part by its runner letter and number before cutting.
- Cut Parts: Use a hobby nipper (sold separately) to carefully cut each part from its runner. Cut slightly away from the part, then trim the remaining nub for a clean finish. Avoid pulling or twisting, which can damage the part.
- Assemble Sections: Follow the numerical sequence in the graphical instructions to assemble individual sections (e.g., head, torso, arms, legs). Pay attention to part orientation.
- Connect Sections: Once individual sections are complete, connect them to form the full mobile suit. Ensure all connections are firm.

Operating and Features
The Psycho Gundam Mk-II model kit offers several dynamic features once assembled, allowing for various display options and poses.
Articulation
The model features extensive articulation in its joints, including movable limbs, head, and waist sections. This allows for a wide range of dynamic poses, capturing iconic scenes from the Mobile Suit Z Gundam series.
Mobile Fortress Transformation
A key feature of the Psycho Gundam Mk-II is its ability to transform into Mobile Fortress mode. Follow the specific instructions in the graphical manual to reconfigure the limbs and body panels for this alternate mode. This transformation is designed to be smooth and accurate to the original design.

- Weapon Display Base: Utilize this base to showcase the model's weaponry or effect parts separately, adding depth to your display.
- Effect Parts: Various beam saber effects and other energy effects are included to simulate combat scenarios.

Maintenance
To ensure the longevity and pristine appearance of your model kit, follow these maintenance guidelines:
- Cleaning: Dust the model regularly with a soft brush or compressed air. Avoid using harsh chemicals, solvents, or abrasive materials, as these can damage the plastic or paint.
- Handling: Always handle the model by its main body parts to avoid stressing smaller, delicate components or joints.
- Storage: Store the model away from direct sunlight, high humidity, and extreme temperatures to prevent plastic degradation, discoloration, or warping. A display case can help protect it from dust.
Troubleshooting
If you encounter any issues during or after assembly, consider the following common solutions:
- Loose Parts: If a part feels loose, ensure it is fully pressed into place according to the instructions. For persistent looseness, a very small amount of clear hobby cement (sold separately) can be applied carefully to the joint, though this is rarely necessary for Bandai snap-fit kits.
- Difficult Assembly: Double-check the graphical instructions to ensure parts are oriented correctly and that you are using the right components for each step. Do not force parts together; if they don't fit, re-examine the connection points for obstructions or incorrect alignment.
- Missing Parts: Thoroughly check all runners and the packaging for any small parts that might have detached or been overlooked. If a part is genuinely missing, refer to the warranty and support section.
