Assembly Instructions
Careful assembly is key to achieving the best results with your Tamiya model kit. Please read all instructions thoroughly before beginning.
Included Components
- Plastic parts for the Ferrari F189 chassis, body, engine, and suspension.
- Rubber tires with realistic tread.
- Waterslide decals for authentic markings and sponsor logos.
- Driver figure.
- Instruction booklet (this manual).
- Additional small parts for detail (e.g., screws, metal shafts).
General Assembly Steps
- Preparation: Carefully remove parts from the sprues using a hobby knife or nippers. Smooth any rough edges with sandpaper or a file.
- Painting (Optional but Recommended): Paint individual parts according to the color guide provided in the original kit's instruction booklet before assembly for a professional finish.
- Engine Assembly: Assemble the detailed V10 engine components. Ensure all parts fit snugly.
- Chassis and Suspension: Attach suspension arms, wheels, and tires to the chassis. Pay attention to alignment for proper stance.
- Body and Cockpit: Assemble the main body sections, including the cockpit and driver figure. The model features a removable cowling for viewing the internal details.

Display and Handling
Once assembled, your Tamiya Ferrari F189 model is intended for display. Proper handling will preserve its condition.
- Display Location: Place the model on a stable, flat surface away from direct sunlight, extreme temperatures, and high humidity to prevent material degradation and decal fading.
- Handling: Always handle the model by its main body or chassis. Avoid touching delicate parts like wings, mirrors, or antennas, as they can be fragile.
Maintenance
Regular, gentle maintenance will keep your model looking its best.
- Dusting: Use a soft, dry brush or a can of compressed air to gently remove dust. Avoid abrasive cloths or harsh chemicals.
- Cleaning: For stubborn marks, lightly dampen a cotton swab with water (or a very mild, model-safe cleaner if necessary) and gently wipe the affected area. Test on an inconspicuous area first.
- Storage: If storing the model for an extended period, place it in a sealed display case or box to protect it from dust and environmental factors.
Troubleshooting
While Tamiya kits are known for their precision, minor issues can sometimes arise during assembly.
- Parts Not Fitting:
Ensure you are using the correct parts as indicated in the kit's instruction booklet. Check for excess plastic (flash) on the parts and carefully trim it away. Sometimes, a small amount of sanding can improve fit.
- Decals Not Adhering:
Ensure the surface is clean and smooth. Use decal setting solution to help the decal conform to irregular surfaces and adhere better. Allow sufficient drying time.
- Paint Issues:
Ensure surfaces are clean and primed before painting. Apply paint in thin, even coats to avoid runs or thick textures. Allow each coat to dry completely before applying the next.
For more specific issues, refer to the detailed instructions provided with your physical model kit or consult online modeling communities for advice.
