2. Safety Information

This model kit contains small parts and sharp components. Adult supervision is recommended for builders under the age of 14.

• Keep out of reach of small children to prevent choking hazards.
• Use appropriate tools safely, such as hobby knives and nippers.
• Work in a well-ventilated area when using paints, glues, and solvents.
• Avoid contact of glues and paints with skin and eyes. In case of contact, rinse immediately with water and seek medical attention if irritation persists.
• Dispose of waste materials responsibly.

3. Parts List and Preparation

Before beginning assembly, carefully unpack all components and compare them against the parts list provided in the physical kit box. Ensure all parts are present and undamaged.

Remove parts from their sprues using a hobby nipper or knife, trimming any excess plastic (flash). Smooth rough edges with sandpaper or a hobby file.

It is recommended to wash plastic parts with mild detergent and water to remove mold release agents, which can interfere with paint adhesion. Allow parts to dry completely.

5. Detailing: Add smaller components such as handlebars, footpegs, and clear parts.

Use plastic cement specifically designed for model kits. Apply sparingly to avoid damaging plastic surfaces. Allow sufficient drying time between steps.

5. Painting and Decal Application

Refer to the color guide in your kit for recommended paint colors. Apply paint in thin, even coats to achieve a smooth finish. Allow each coat to dry thoroughly before applying the next.

For decals, cut them carefully from the sheet. Dip each decal in lukewarm water for a few seconds until it can slide freely from the backing paper. Position the decal on the model and gently slide the backing paper away. Use a soft cloth or cotton swab to carefully press out any air bubbles and excess water. A decal softener may be used to help decals conform to curved surfaces.

6. Maintenance

To preserve the appearance of your finished model:

• Keep the model in a dust-free environment, ideally in a display case.
• Clean gently with a soft, dry brush or a slightly damp cloth. Avoid harsh chemicals or abrasive cleaners.
• Protect from direct sunlight and extreme temperatures to prevent fading or warping.

7. Troubleshooting Common Issues

Problem: Parts do not fit together correctly.

• Solution: Check for excess plastic (flash) on the edges of the parts and trim as necessary. Ensure parts are oriented correctly according to the instructions.

Problem: Paint finish is uneven or rough.

• Solution: Ensure surfaces are clean and free of dust before painting. Apply paint in multiple thin coats rather than one thick coat. Allow adequate drying time between coats.

Problem: Decals do not adhere or wrinkle.

• Solution: Ensure the surface is smooth and glossy. Use decal setting solution to help decals conform and adhere better. Gently remove air bubbles.
