Paxar Rewind Monarch 415 - Manual (Page 13)

4. Changing Hubs
If you change to a different supply, you may need to use a
different hub. One, three, and four inch diameter hubs (short
and long) are available from Monarch.
To change hubs
1. Pull the supply guide away from the hub (Figure 9).
2. Unscrew the hub knob (Figure 10).
NOTE: The hub diameter must be the same as the inside
diameter of the supplies.
