Take a shirt or a clean rag and wipe your bearing edges clean, and also check the head for any imperfections like dust as well. When you tune the head up the first time, seat it by pushing down in the center while tuning in a normal star pattern. Consider how high you will want this head to be tuned, and tune it approximately one note higher and do this for all new heads. Come back in 24 hours, and tune down a little bit to your desired pitch and the head will be ready to play.
