2. Setup
Your Wilson Ultra 100L V4.0 tennis racket is supplied unstrung, allowing for personalized string selection and tension. Proper stringing is crucial for optimal performance.
2.1 Stringing the Racket
- Professional Stringing Recommended: It is highly recommended to have your racket strung by a certified tennis professional. They can advise on appropriate string types and tensions based on your playing style and preferences.
- String Tension: Refer to the racket's specifications (usually printed on the frame or in the specifications section of this manual) for the recommended string tension range. Stringing outside this range may void the warranty or damage the frame.
- Grommet Inspection: Before stringing, ensure all grommets are intact and properly seated. The racket features a Crush Zone grommet system and an Expanded Sweet Spot Channel, designed to enhance string movement.
2.2 Initial Inspection
Upon receiving your racket, inspect it for any visible damage to the frame, grip, or bumper guard. If any damage is present, contact your retailer immediately.

3. Operating the Racket
The Wilson Ultra 100L V4.0 is engineered to provide a blend of power, comfort, and maneuverability. Understanding its design features can help optimize your performance.
3.1 Grip and Handling
- Grip Size: This model features a Grip Size 0 (4") for comfortable handling. Ensure your grip size is appropriate for your hand to prevent discomfort and optimize control.
- Balance: The racket's revised geometry aims for a more comfortable, ergonomic design while maintaining stability, contributing to its maneuverability for quick exchanges.
3.2 Performance Features
- FORTYFIVE° Technology: Strategically embedded into the lay-up, FORTYFIVE° provides enhanced stability and increases comfort during play.
- Expanded Sweet Spot Channel: A cavity on the inside of the frame extends the cross strings and increases grommet movement, resulting in more power and easier court depth.
- Crush Zone Grommet System: This system compresses at impact, boosting power and increasing ball dwell time on the strings for improved feel and control.
- Parallel Drilling: Provides a consistent and more forgiving string bed response across the entire hitting surface.

4. Maintenance
Regular maintenance will extend the lifespan and preserve the performance of your Wilson Ultra 100L V4.0 tennis racket.
- Grip Care: The grip can accumulate sweat and dirt. Wipe it down with a damp cloth after use. If the grip becomes slick or worn, consider replacing the overgrip or the base grip.
- Frame Cleaning: Clean the racket frame with a soft, damp cloth. Avoid abrasive cleaners or solvents that could damage the finish or materials.
- String Inspection: Regularly check your strings for fraying, notching, or breakage. Worn strings can significantly reduce performance and increase the risk of arm injury. Restring as needed, typically every 20-40 hours of play or at least twice a year for recreational players.
- Bumper and Grommet Inspection: Inspect the bumper guard and grommets for wear or damage. These components protect the frame and strings. The Agiplast plant-based bumper, grommet, and end cap components are designed for durability and reduced environmental footprint.
- Storage: Store your racket in a cool, dry place, away from direct sunlight and extreme temperatures. High heat can warp the frame, and cold can make it brittle. Using a racket bag provides protection during transport and storage.
