1. Inflate Properly: Use a dedicated inflation needle and lubricate it before slowly inserting into the valve for inflation. Do not inflate directly with a high-pressure pump; the ball's inflation pressure should be between 7-9 pounds per square inch (PSI) Test method: On a flat hard surface, the basketball is dropped from 1 8m Free fall from height, rebound height should be 1 2-1. Between 4m is normal 2. Don't inflate the ball too much, especially in summer; Do not kick the basketball with your feet or sit on it to rest; do not forcefully slam the basketball to prevent deformation and bulging 3. The new ball feels a bit slippery after hitting outfield due to dust accumulation; it needs some break-in time for better feel After use, you should clean the surface of the ball. You can wipe it clean with a damp towel; do not wash it with water. Store it in a cool and dry place so that it won't feel sticky next time you play 4. Do not play on rainy days or when there is water on the court. If the ball gets wet, use a towel to dry it and place it in a ventilated and dry area. Never expose it to direct sunlight The purpose of not soaking in water is to prevent the ball from opening up 5. Pay attention to clearing the venue and surrounding sharp objects to avoid puncturing or injuring the ball, as well as preventing injuries during exercise 6. If not used for a long time, it should be properly deflated (about 70-80% remaining air) and stored in a cool and dry place. Do not completely deflate or flatten the ball as this can easily cause the skin to peel off 7. In case the ball's leather partially peels off, you can use shoe repair glue or other soft adhesive to fix it. Alternatively, you can go to a shoe repair shop for assistance. Remember not to use hard glues like 502 Because 502 is a hard glue, using it on the ball cover not only results in poor adhesion but also causes partial hardening of the cover, affecting the feel of the ball 8. In case the valve leaks, don't throw the ball away easily because most basketballs have replaceable valves
