The head is an expendable item that eventually will 
wear out and need to be replaced. Replace the head 
when the following occurs:
Slack portions remain in the head even when the head tension
is properly adjusted.
Replacement heads (optional): MH-8 Mesh Head
1.
Remove all tuning bolts from the PDX-8.
fig.Replace.e
Do not apply excessive force to the sensor and cushion 
located under the head. Doing so can interfere with 
accurate detection, and may damage it.
2.
Remove the hoop.
3.
Remove the old head.
4.
Place the new head on the shell.
5.
Place the hoop onto the head.
6.
Attach the tuning bolts to the hoop and shell.
7.
Next, adjust the tension of the head. Refer to
“Adjusting the Head Tension” (p. 4).
Do not firmly tighten a single tuning bolt by itself. Doing 
so will make it impossible to tension the head evenly, and 
will cause malfunctions.

* In the interest of product improvement, the specifications and/
or appearance of this unit are subject to change without prior 
notice.
* The Rim rubber is one component that eventually wears out
(the more so if numerous rim shots are performed), and will 
require replacement. Rim shots may not be performed correctly 
when the rim rubber is worn out. If this occurs, replace the rim 
rubber. Consult Roland Service for more on replacing the rim 
rubber.
