2. Safety Information

WARNING: CHOKING HAZARD - Small parts. Not for children under 3 years.

This building set contains numerous small components. Keep all parts out of reach of young children to prevent accidental ingestion. Adult supervision is recommended during assembly, especially for younger builders.

3. Assembly Instructions

The COBI DR BR 03 Steam Locomotive building set is designed for intuitive assembly. The instruction manual included in the box provides clear, step-by-step directions with illustrations. Please refer to the physical instruction manual for the detailed building sequence.

3.1 General Assembly Tips

• Organize Parts: Before starting, sort the 2564 elements by type or color to facilitate easier identification during construction.
• Follow Steps Sequentially: Adhere strictly to the numbered steps in the instruction manual. Do not skip steps.
• Check Connections: Ensure all blocks are firmly pressed together to create a stable and durable model.
• Patience: Some connections may be tight. Apply steady, even pressure. Avoid forcing pieces excessively.

3.2 Key Features During Assembly

4. Operation

Once assembled, the COBI DR BR 03 Steam Locomotive is primarily a display model, but it incorporates several interactive features:

• Rolling Movement: The locomotive can be manually pushed along the included track sections. The rotating gears and pistons will move in conjunction with the wheels, simulating a real steam engine's motion.
• Opening Smoke Box: The front smoke box can be opened, revealing internal details.
• Removable Coal Load: The coal load in the tender can be removed or re-inserted, allowing for varied display options.
• Articulated Tender Wheels: The tender's wheel bogies are designed to articulate, allowing the model to navigate curves on compatible track systems.

5. Maintenance

To ensure the longevity and appearance of your COBI DR BR 03 Steam Locomotive model, follow these simple maintenance guidelines:

• Cleaning: Dust the model regularly with a soft, dry cloth or a soft brush. For more thorough cleaning, use a slightly damp cloth with mild soap and water, then wipe dry immediately. Avoid harsh chemicals or abrasive cleaners.
• Storage: Store the model in a cool, dry place away from direct sunlight and extreme temperatures to prevent discoloration or warping of the plastic elements.
• Handling: Handle the model carefully, especially when moving it, to avoid accidental detachment of parts.

6. Troubleshooting

6.1 Missing or Damaged Parts

In the rare event that you find a part missing or damaged upon opening your set, please contact COBI customer support. Provide details of the missing part (e.g., part number from the instruction manual, description, and quantity) and your proof of purchase. Do not discard the packaging until assembly is complete and all parts are accounted for.

6.2 Difficulty Connecting Parts

Some building blocks may have a tighter fit than others. If you encounter difficulty connecting parts:

• Ensure the parts are correctly oriented according to the instructions.
• Apply firm, steady pressure. Avoid twisting or bending parts excessively.
• If a part is consistently too tight, try connecting it to a different, similar piece to check if the issue is with the specific block or your technique.
