Advice on a Hoffmann dovetail key router

[PassionforWood]

I'm new on here & think that I posted this in the wrong place last night.

Just purchased a used Hoffmann MU2 dovetail key routing machine, looked through the manual & don't seem to be able find any info on how to rout out the haunched upright. The frames that I am trying to join are moulded with a cock bead moulding, the uprights i have haunched & the cross rails I have mitred, it is just the routing that I am having problems with.
Do I need to purchase a larger dovetail cutter? The dovetail keys that came with the machine are W2s
Any help appreciated.
Thanks

Hello All, just curious about the Hoffmann mu2 - does anyone know the model number for the actuator at the back of the machine?

Thanks in advance.
