3. Edge roll
Tools: None.
Dismantling duration: 20 seconds.
Mounting duration: 45 seconds.
The edge roll is replaceable. It is attached to the rim by means of press studs
(3 on each side) and adjusts to fit the shell by means of two fastening pins. No tools are
needed for its removal and reinstallation.
When removing the edge roll, it is best to take out the ear cups and the neck pad first.
Then detach the 6 press studs and remove the 2 pins. When removing the first pin, it is
important to twist the edge roll then slide the pin along its slot. The second pin will then
come out easily on its own.
To reinstall the edge roll, engage the pins one after the other in the slots,
then fasten the press studs.
