I think if you may find it frustrating if you’re thinking of using the machine in a conventional way. The lever arrangement is really meant for limited and repetitive action — say running a small part through a pair of slitting blades to quickly cut two slots and then changing in another part to repeat the operation over again — and trying to perform normal milling operations with that setup could be pretty challenging. I imagine it could be done, but i don’t think it would be ideal. Having said that, I’ve not used a lever-operated machine so have no firsthand experience. My MF has the normal lead screws and feed mechanism, but I think there may be someone on the forum who does have a lever machine so hopefully he sees this and can comment.
