5. Operating Instructions
The LEGO Speed Champions Time Machine is designed for display and imaginative play. To switch between the 1985 road version and the flying version, partial disassembly and reassembly are required as per the instruction manual. The wheels do not automatically pivot for flying mode; specific parts must be exchanged.
5.1. Minifigure Placement
The Doc Brown and Marty McFly minifigures can be placed inside the car's cockpit. The windshield element can be easily removed to access the interior for minifigure placement.
5.2. Changing Build Modes
To transform the DeLorean from the 1985 version to the flying version (or vice-versa), refer to the specific sections in your instruction booklet. This involves removing and attaching different components such as the lightning rod, license plates, Mr. Fusion, and adjusting the wheel configuration.

6. Maintenance
To ensure the longevity and appearance of your LEGO set:
- Cleaning: Use a soft brush or a damp cloth with mild soap to gently clean dust and dirt from the bricks. Avoid harsh chemicals or abrasive materials.
- Storage: Store the assembled model or loose bricks in a cool, dry place away from direct sunlight to prevent discoloration and damage.
- Handling: Handle the model with care to prevent accidental disassembly, especially when moving or displaying.
7. Troubleshooting
- Missing Pieces: If you find any missing pieces during assembly, please contact LEGO Customer Service directly through their official website.
- Assembly Difficulties: Refer to the LEGO Builder app for interactive 3D instructions, which can provide clearer visual guidance than the printed manual. Ensure all connections are firm.
- Parts Not Attaching Properly: Double-check the instruction steps. Sometimes, a small misalignment can prevent larger sections from connecting correctly. For this model, ensure the pegs above the wheel wells are attached first for proper base assembly.
