3. Initial Setup and Inspection
Before first use, carefully remove the cube from its packaging. Inspect the cube for any visible damage. The GAN 251 M Pro comes pre-assembled and ready for use. No additional assembly is required.
The cube features a frosted surface for enhanced grip and scratch resistance. The internal mechanism includes a magnetic core for improved stability and turning feel.

4. Operating Your Speed Cube
The GAN 251 M Pro is a 2x2 speed cube designed for smooth and fast rotations. To operate, simply hold the cube and rotate its layers horizontally and vertically. The magnetic system assists in aligning the layers, providing a crisp and stable turning experience.
The cube's rounded track system and optimized corner cutting (55° positive, 35° reverse) allow for fluid movements and forgiveness during solves.

5. Tuning and Adjustment
The GAN 251 M Pro offers extensive tuning options to customize the cube's feel and performance. This model features the GES v3 (GAN Elasticity System) and GMS v3 (GAN Magnetic System) for precise adjustments.
5.1. GES v3 (GAN Elasticity System)
The GES v3 system allows you to adjust the center piece travel distance and spring tension. The GAN 251 M Pro is equipped with 2 kinds of nut distances and 4 levels of elasticity. These adjustments influence the cube's tightness and turning speed.

5.2. GMS v3 (GAN Magnetic System)
The GMS v3 system allows for adjustable magnet strength. The GAN 251 M Pro offers 3 settings for magnet strength (weak, medium, strong), providing further customization of the cube's tactile feedback and stability.

5.3. Magnetic Core Technology
The GAN 251 M Pro features a magnetic core, which integrates magnets directly into the core and pieces. This design enhances stability and provides a smoother, lighter turning feel compared to traditional magnetic cubes.

5.4. Tuning Video Guide
For a visual guide on how to adjust the center piece travel and spring tension using various GAN Elasticity Systems (GES), please watch the official video below. While the video covers multiple GAN cubes and GES versions, the principles for adjusting the GAN 251 M Pro's GES v3 system are similar.

6. Maintenance
To ensure the longevity and optimal performance of your GAN 251 M Pro, follow these maintenance tips:
- Cleaning: Wipe the cube regularly with a soft, dry cloth to remove dust and fingerprints. Avoid using harsh chemicals or abrasive materials.
- Lubrication: If the cube feels stiff or sluggish over time, apply a small amount of speed cube lubricant to the internal mechanism. Rotate the layers to distribute the lubricant evenly. Use lubricants specifically designed for speed cubes.
- Storage: Store the cube in its original box or a protective pouch to prevent dust accumulation and accidental damage.
- Avoid Extreme Conditions: Do not expose the cube to extreme temperatures, direct sunlight for prolonged periods, or excessive moisture, as this can affect the plastic and internal components.
7. Troubleshooting
Here are some common issues and their solutions:
- Cube feels too loose or too tight: Adjust the GES v3 system as described in Section 5.1 to achieve your preferred tension and travel.
- Magnets feel too strong or too weak: Adjust the GMS v3 system as described in Section 5.2 to change the magnet strength.
- Cube feels sluggish or gritty: The cube may need lubrication. Refer to the "Lubrication" point in Section 6.
- Cube "pops" (pieces come apart): This usually indicates the tension is too loose. Tighten the GES v3 system. Ensure all pieces are correctly assembled.
