Preparations
Replacing the Head
The head is an expendable item, whose performance deteriorates with extended use. If the
head has torn out or remains slack even after proper adjustment, then replace the head.

Replacing the Head
When replacing, use the included tuning key.
1. Remove all tuning bolts and washers.
Go around and gradually loosen each one in order (by turning it counterclockwise).
Be careful not to lose the tuning bolts and washers that you removed.
2. Remove the hoop.
3. Remove the old head.
4. Place the new head on the frame.
5. Place the hoop onto the head.
6. Pass the tuning bolts through the washers, then attach them to the hoop and frame.
7. Tighten all eight tuning bolts until they lightly contact the hoop.
8. Next, adjust the tension of the head. Refer to "Adjusting the Head Tension" (p. 11).
