Step-by-Step Assembly
- Build Step 1: Chassis Welding and Forming
Begin by assembling the tank chassis. The conveyor rail is designed to transport the tank chassis to the "welder" position for fixed assembly. Utilize the sliding rail function to move the chassis into place.

Figure 3: Chassis assembly and use of the sliding rail function.
- Build Step 2: Power System Transportation and Installation
Proceed to the power installation control area. Use the forklift to transport the core power pack and integrated tracks to their designated placement area. The forklift can also be used to move the tank's core power pack and fuel tank components.

- Build Step 3: Main Turret System Installation
Move to the digital assembly control area. Position the crane to release the main turret onto the tank chassis for pre-welding and forming. The rotating gear allows for lifting and lowering the turret, and a switch releases it into position.

- Build Step 4: Spray Painting and Subsystem Installation
Finally, enter the surface treatment area for digital camouflage spray painting. Install various sensors and sub-weapons in their designated places to complete the tank's construction.

Maintenance
To ensure the longevity and enjoyment of your SEMBO building block set, follow these simple maintenance guidelines:
- Cleaning: Use a soft, dry cloth to gently wipe away dust and dirt from the blocks. For stubborn grime, a slightly damp cloth can be used, but ensure all parts are thoroughly dried afterwards.
- Storage: Store the assembled model or loose blocks in a cool, dry place away from direct sunlight to prevent discoloration or warping. Keep small pieces in a container to avoid loss.
- Handling: Handle the model with care to prevent accidental disassembly or damage to delicate parts.
Troubleshooting
If you encounter any issues during assembly or play, consider the following common solutions:
- Missing Pieces: Double-check the packaging and surrounding area. If a piece is genuinely missing, contact customer support with details of the missing part.
- Difficulty Connecting Blocks: Ensure blocks are aligned correctly and apply firm, even pressure. Some new blocks may require a bit more force initially.
- Model Instability: Review the assembly steps to ensure all connections are secure and no steps were missed. Loose connections can lead to instability.
- Lighting Not Working: Check the battery compartment of the lighting component box (if applicable) for proper battery insertion and charge. Ensure the switch is in the "on" position.
User Tips
- Organize First: Before starting assembly, sort all the pieces by color and type. This will significantly speed up the building process and reduce frustration.
- Follow Instructions Closely: Building block sets can be complex. Pay close attention to the instruction manual's diagrams and steps to avoid errors.
- Take Breaks: If you feel frustrated or tired, take a break. Returning to the build with fresh eyes can help you spot mistakes or find solutions.
- Display with Pride: Once completed, this detailed model makes an excellent display piece. Consider placing it in a prominent location to showcase your building skills.
