- Model paints (acrylic recommended)
- Hobby knife or sprue cutters
- Small files or sandpaper
- Tweezers
- Paintbrushes
General Assembly Steps:
- Preparation: Carefully remove parts from the sprues using a hobby knife or sprue cutters. Clean any flash or mold lines with a file or sandpaper.
- Painting: Paint individual components according to your desired scheme. Refer to the included decal sheet for color suggestions and placement. Allow paint to dry completely before proceeding.
- Engine Assembly: Assemble the Detroit Diesel 60 series 420 horsepower engine components. Ensure all parts fit securely.
- Chassis and Suspension: Construct the Peterbilt Air Trac air ride suspension and chassis. Attach the 10 thermoplastic rubber tires to the wheels and then to the axles.

Always refer to the detailed diagrams and step-by-step instructions provided in the physical instruction guide included with your kit for precise assembly sequences and part identification.
Operating Features
This model kit is designed for display and features several movable components that enhance its realism:
- Steerable Front Axle: The front wheels can be turned left and right, simulating steering. Handle gently to avoid damage.
- Tilting Hood: The hood can be opened to reveal the detailed Detroit Diesel engine compartment. Exercise care when opening and closing.
- Functional Fifth Wheel: The fifth wheel is designed to articulate, allowing for connection to a compatible trailer (trailer not included).
Note: This is a static display model kit and is not intended for motorized operation or rough play.
Maintenance
Proper care will preserve the appearance and integrity of your model for years to come.
- Cleaning: Dust your model regularly with a soft, dry brush or a can of compressed air. Avoid using harsh chemicals or abrasive materials, which can damage paint and decals.
- Storage: Store the model in a cool, dry place away from direct sunlight and extreme temperature fluctuations. Prolonged exposure to sunlight can cause decals to fade and plastic to warp.
- Repairs: If parts become detached, reattach them using plastic model cement. For paint chips, touch up with appropriate model paints.
Troubleshooting Common Issues
- Parts not fitting: Ensure all flash is removed from the parts. Dry-fit components before applying cement. If a part is slightly warped, gentle heat (e.g., from a hairdryer) can sometimes help reshape it, but proceed with caution.
- Decals not adhering: Ensure the surface is clean and smooth. Use a decal setting solution to help decals conform to irregular surfaces and adhere better.
- Paint issues: Apply paint in thin coats to avoid brush marks or loss of detail. Allow sufficient drying time between coats.
- Missing parts: Double-check the sprues and packaging. If a part is genuinely missing, contact AMT customer support (see Support section).
