Contingut del paquet
Your package should contain all the necessary building blocks and components to construct the 4WD Independent Suspension Differential Chassis. Some parts may come in random colors, but this will not affect the functionality or assembly process.
Un example of the parts included is shown below:

Instruccions de muntatge
Detailed step-by-step assembly instructions are provided in a PDF manual. To access the complete assembly guide, please scan the QR code located on the product packaging bag. Alternatively, you can download the PDF directly from the following link: Manual d'usuari (PDF).
The assembly process involves connecting various building blocks to form the chassis, including the independent suspension, differential gears, and steering axle components. Pay close attention to the diagrams and part counts for each step.


Funcions operatives
Once assembled, the MOC 4WD chassis demonstrates several key mechanical principles:
- Tracció a les quatre rodes (4WD): Power is distributed to all four wheels, enhancing traction and maneuverability.
- Suspensió independent: Each wheel can move vertically independently, allowing the chassis to maintain contact with uneven surfaces and providing a smoother ride.
- Diferencial: The differential allows wheels on the same axle to rotate at different speeds, which is crucial for smooth turning.
- Steering Axle: The front axle is designed for steering, enabling directional control of the chassis.
You can observe the suspension and steering mechanisms in action by gently manipulating the chassis:


Manteniment
To ensure the longevity and optimal performance of your MOC chassis:
- Neteja: Wipe the assembled chassis with a soft, damp drap per eliminar la pols i la brutícia. Eviteu utilitzar productes químics o materials abrasius.
- Inspecció: Periodically check for any loose connections or detached parts. Re-attach or tighten as necessary.
- Emmagatzematge: Store the chassis in a cool, dry place away from direct sunlight and extreme temperatures to prevent material degradation.
Resolució de problemes
- Peces que no encaixen: Double-check the assembly steps in the PDF manual. Ensure you are using the correct parts for each step and that they are oriented correctly.
- Chassis not moving smoothly: Verify that all axles and gears are properly aligned and connected. Ensure no parts are rubbing against each other unnecessarily.
- Peces que falten: If you believe you are missing any essential components, please refer to the warranty and support section for assistance.
