MOC Medieval Dark Style Building Blocks Instruction Manual

1. Product Overview

1.1 Product Introduction

This set of building blocks adopts Lego's universal connection system design, with all parts complying with Lego standard size specifications. It is fully compatible with Lego blocks from different years and series. The product is made of food-grade ABS environmental protection plastic, free of harmful substances such as bisphenol A (BPA) and phthalates. It has passed international safety certifications including ASTM F963-23 (USA), EN 71 (EU), and GB 6675 (China) to ensure safe use.

1.2 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

2.1 Preparations

1. Part Classification: Unpack sequentially according to the bag labels in the manual (marked "Step 1 -XX"). For unpackaged parts, it is recommended to store them by color and shape, and store special parts (gears, axles, ball joints) separately.
2. Tool Preparation: Basic tools include a brick separator (for separating tightly fitted parts) and a soft brush (for cleaning dust). Optional parts sorting boxes and magnetic storage trays can improve efficiency.
3. Environmental Requirements: Choose a spacious and flat tabletop or floor, preferably with a non-slip mat. Avoid using in humid or narrow areas.

2.2 Basic Assembly Skills

1. Connection Method: Align the anti-studs of the upper block with the studs of the lower block, press vertically downward until fully engaged, and a "click" sound indicates successful fixation.
2. Structural Reinforcement:
   • Vertical Stacking: For every 5 additional layers, it is recommended to add horizontal supports (such as 1x2 plates) to enhance stability.
   • Horizontal Splicing: Adopt the "interlocking structure" (upper bricks cover the gaps of lower bricks) to increase bending resistance by 30%.
3. 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 avoid jamming. Add 1 idler gear for every 5 gears in gear transmission to reduce wear.

2.3 Advanced Assembly Suggestions

• Color Matching: Follow the "7:2:1 Rule" (70% main color + 20% auxiliary color + 10% accent color) to avoid messy colors.
• Modular Construction: Split complex models into independent subsystems (foundation, main body, decoration) first, then assemble them as a whole to reduce error rate.
• Dynamic Structures: Balance flexibility and stability at the connection points of movable parts to avoid excessive looseness or tightness.

2.4 Interpretation of Manual Symbols

Electronic Instructions: This MOC building block kit is equipped with electronic instructions. Please provide an email address to the seller to receive the electronic instruction manual. All parts will be inspected before delivery. If you find some missing or damaged parts, you can provide a free supplement once (due to freight considerations, supplements will be sent with your next purchase from the store).

3. Maintenance

3.1 Cleaning Methods

1. Regular Cleaning: Soak in mild soapy water, wipe gently with a soft cloth or sponge. Avoid using chlorine bleach or strong corrosive cleaners.
2. Gap Cleaning: Use a soft brush or a hair dryer on low temperature to clean dust in part gaps.
3. Drying: Thoroughly dry after cleaning to prevent moisture residue and bacterial growth.

3.2 Storage and Preservation

1. Store in a dry and well-ventilated place to avoid part aging due to humid environments.
2. Use sorting boxes or storage bags to organize parts by type to prevent loss.
3. Avoid direct sunlight to prevent color fading and material embrittlement.
4. For long-term non-use, it is recommended to disassemble large assembled models to reduce part fatigue and wear.

3.3 Regular Inspection

1. Inspect the integrity of blocks weekly. Immediately stop using and replace any damaged, cracked, or deformed parts.
2. Store small and large bricks separately to prevent young children from accessing small bricks.

4. Troubleshooting

• Missing or Damaged Parts: If parts are lost or damaged, contact official customer service for replacement according to the part number in the manual's parts list.
• Jamming Movable Parts: Ensure a 1-2mm gap is reserved for ball joints during assembly to prevent jamming. For gear transmissions, add 1 idler gear for every 5 gears to reduce wear.

5. Specifications

6. Safety Precautions

6.1 Usage Specifications

1. Do not put blocks (especially small ones) into the mouth, nostrils, or ears to avoid suffocation risk.
2. Do not use blocks as projectiles or weapons, and prohibit use during horseplay.
3. Children aged 3-6 must be accompanied by adults during use, and unsafe behaviors should be corrected in a timely manner.
4. Avoid playing while running or jumping to prevent falling and injury from stepping on scattered blocks.

6.2 Prohibited Scenarios

1. Electronic parts (motors, battery boxes, sensors) are prohibited from contacting water sources to avoid short circuits, damage, and safety risks.
2. Do not immerse assembled mechanical components (such as gearboxes) in water to prevent internal mold growth.
3. Do not use metal tools to forcefully pry or disassemble parts to avoid fragmentation and sharp edges.
4. It is not recommended to use blocks as decorations in aquariums or fish tanks.

6.3 Compliance
