Setup
Initial Inspection
Carefully remove the cube and all accessories from the packaging. Inspect the cube for any visible damage or manufacturing defects. The cube features a stickerless design, meaning the colors are integrated into the plastic, preventing fading or peeling.

Adjustment System
The MoYu RS3 M 2020 is equipped with a dual-adjustment system, allowing you to customize the cube's tension and elasticity. This system includes a screwdriver for adjusting screw tension and a separate tool for spring compression.
- To access the adjustment mechanism, gently pry off the center cap on each face of the cube.
- Use the provided screwdriver to adjust the screw tension. Turning clockwise increases tension, making the cube tighter; turning counter-clockwise decreases tension, making it looser.
- Use the specialized tensioning tool to adjust the spring compression. This fine-tunes the cube's elasticity and feel.
- Adjust each side evenly to maintain balance and optimal performance.

Lubrication
For enhanced smoothness and reduced friction, it is recommended to lubricate the cube's core and pieces. While the cube performs well out of the box, lubrication can further improve its turning feel and reduce any potential spring noise.
- Carefully disassemble a few pieces to expose the core.
- Apply a small amount of cube-specific lubricant to the core and the contact points of the pieces.
- Reassemble the cube and make a few turns to distribute the lubricant evenly.
Operating Instructions
Basic Operation
The MoYu RS3 M 2020 is designed for smooth and effortless turning. Its magnetic positioning system provides a satisfying tactile feedback, helping pieces align precisely during fast solves. The cube's advanced design allows for excellent corner cutting, which is crucial for speedcubing.
Benefits of Magnetic Design
The factory-installed magnets within the cube's pieces provide a subtle "snap" sensation, guiding the layers into place. This magnetic assistance contributes to increased stability, control, and overall speed during solving, making it quieter than traditional non-magnetic cubes.
Maintenance
Cleaning
To maintain optimal performance and appearance, regularly clean your speed cube. Use a soft, dry cloth to wipe down the exterior surfaces. For internal cleaning, carefully disassemble the cube and remove any dust or debris from the pieces and core using a soft brush or compressed air.
Lubrication Schedule
The frequency of lubrication depends on usage. For regular use, re-lubricate the cube every few weeks or whenever you notice a decrease in smoothness or an increase in friction. Always use lubricants specifically designed for speed cubes to avoid damaging the plastic.
Storage
Store your cube in a clean, dry place away from direct sunlight and extreme temperatures. The included MoYu cube stand can be used for display and to keep the cube free from dust when not in use.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Cube feels stiff or sluggish | Lack of lubrication; tension too high. | Apply speed cube lubricant; slightly loosen screw tension using the provided screwdriver. |
| Spring noise during turns | Dry springs or core. | Disassemble the cube, apply lubricant to the core and springs, then reassemble. |
| Pieces pop out frequently | Tension too low; aggressive turning. | Slightly tighten screw tension; practice smoother turning techniques. |
| Uneven turning on different faces | Uneven tension settings. | Adjust the tension on each face evenly using the adjustment tools. |
