1. Product Overview
This building block set features a racing car from the Technology Series, designed with a universal connection system compatible with standard building blocks from various brands and series. The product is crafted from food-grade ABS environmental protection plastic, free from harmful substances such as bisphenol A (BPA) and phthalates. It has successfully passed international safety certifications including ASTM F963-23 (USA), EN 71 (EU), and GB 6675 (China), ensuring safe use.
1.1 Target Audience
- Small brick blocks (regular size): Suitable for children aged 14 and above, and adults.
- Large brick blocks (Duplo series size): Suitable for children aged 14 and above.
Note: Children aged 3-6 must be accompanied by adults during use.
2. Setup and Assembly
The assembly process involves connecting 1077 pieces to construct the detailed racing car model. Follow the instructions carefully for a smooth building experience.
2.1 Preparations
- Part Classification: Unpack parts sequentially according to the bag labels in the manual (e.g., "Step 1-XX"). For unpackaged parts, sort them by color and shape. Store special parts like gears, axles, and ball joints separately.
- Tool Preparation: Basic tools include a brick separator (for tightly fitted parts) and a soft brush (for cleaning dust). Optional sorting boxes and magnetic storage trays can enhance efficiency.
- Environmental Requirements: Choose a spacious, flat tabletop or floor, preferably with a non-slip mat. Avoid humid or narrow areas.
2.2 Basic Assembly Skills
- Connection Method: Align the anti-studs of the upper block with the studs of the lower block. Press vertically downward until fully engaged. A "click" sound indicates successful fixation.
- Structural Reinforcement:
- Vertical Stacking: For every 5 additional layers, add horizontal supports (e.g., 1x2 plates) to enhance stability.
- Horizontal Splicing: Use the "interlocking structure" (upper bricks covering lower brick gaps) to increase bending resistance by 30%.
- Use of Special Parts:
- Cross Pins: Select the appropriate size by comparing with the length marking in the manual.
- Movable Parts: Reserve a 1-2mm gap for ball joints to prevent jamming. Add 1 idler gear for every 5 gears in gear transmission to reduce wear.

- Opening Doors: Both side doors can be opened.
- Steering: The model incorporates mechanical elements that may allow for basic steering functionality, depending on the final assembly.
Engage with the model by exploring its movable components and appreciating the intricate mechanical design.
4. Maintenance
4.1 Cleaning Methods
- Regular Cleaning: Soak blocks in mild soapy water, then gently wipe with a soft cloth or sponge. Avoid using chlorine bleach or strong corrosive cleaners.
- Gap Cleaning: Use a soft brush or a hair dryer on low temperature to clean dust from small gaps and crevices.
- Drying: Thoroughly dry all parts after cleaning to prevent moisture residue and bacterial growth.
4.2 Storage and Preservation
- Store the blocks in a dry and well-ventilated place to prevent part aging due to humid environments.
- Use sorting boxes or storage bags to organize parts by type to prevent loss.
- Avoid direct sunlight to prevent color fading and material embrittlement.
- For long-term non-use, it is recommended to disassemble large assembled models to reduce part fatigue and wear.
5. Troubleshooting
- Damaged/Cracked Parts: Inspect the integrity of blocks weekly. Immediately stop using and replace any damaged, cracked, or deformed parts.
- Lost Parts: If parts are lost, contact customer service for replacement according to the part number in the manual's parts list.
- Jammed Movable Parts: Ensure a 1-2mm gap is reserved for ball joints during assembly to prevent jamming.
- Excessive Wear in Gears: Add 1 idler gear for every 5 gears in gear transmission to reduce wear and prolong component life.
6. Specifications

7. Safety Precautions
7.1 Usage Specifications
- Do not put blocks (especially small ones) into the mouth, nostrils, or ears to avoid suffocation risk.
- Do not use blocks as projectiles or weapons, and prohibit use during horseplay.
- Children aged 3-6 must be accompanied by adults during use, and unsafe behaviors should be corrected in a timely manner.
- Avoid playing while running or jumping to prevent falling and injury from stepping on scattered blocks.
7.2 Prohibited Scenarios
- Electronic parts (if applicable, e.g., motors, battery boxes, sensors) are prohibited from contacting water sources to avoid short circuits, damage, and safety risks.
- Do not immerse assembled mechanical components (such as gearboxes) in water to prevent internal mold growth.
- Do not use metal tools to forcefully pry or disassemble parts to avoid fragmentation and sharp edges.
- It is not recommended to use blocks as decorations in aquariums or fish tanks.
8. User Tips
- Advanced Color Matching: For custom designs, follow the "7:2:1 Rule" (70% main color + 20% auxiliary color + 10% accent color) to achieve aesthetically pleasing results.
- Modular Construction: For complex models, split them into independent subsystems (e.g., foundation, main body, decoration) first, then assemble them as a whole. This approach can significantly reduce the error rate.
- Dynamic Structures: When building movable parts, aim for a balance between flexibility and stability at connection points to avoid excessive looseness or tightness.
