USING THE UNIT SAFELY
When the Head Should Be Replaced
The head is an expendable item that eventually will wear out
and need to be replaced. Replace the head when the following
occurs:
• The head surface is torn
• Striking points are no longer detected correctly, even
when the head tension is properly adjusted.
• Slack portions remain in the head even after the head
tension is properly adjusted.
Replacement heads (optional): MH-8 Mesh Head
1.
Remove all tuning bolts and washers.
* Press the lock bushing (in figure below) in place with your
finger as you remove each tuning bolt, to prevent the bushings
from being pulled off the frame.

For more on the lock bushings, refer to the following
section, “About the Lock Bushings.”
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.
Next, adjust the tension of the head (p. 6).
About the Lock Bushings
The PD-85BK is provided with lock bushings to prevent
rotation and loosening of the tuning bolts caused by vibration
transmitted from the hoop, as the result of using rim shots or
other performance techniques.
If a lock bushing happens to become separated from the frame
while the head is being replaced, position the bushing so its
four slots are aligned with the corresponding ridges in the
frame, then press down firmly on the bushing.
