disabling a seat switch is "thin ice" around here; so hopefully I don't get in trouble for saying this here; but I have 2 suggestions to keep it "able"; ( I won't say "option 3" which is what I'd be more likely to do, myself, but would certainly be "deleted")
either; get someone to set in the seat while you adjust or else (and you wouldnt be able to "run" the machine like this, you'd have to "undo" this temporary fix to be able to actually "use" the machine so here goes; set a cinder block or 2 on the seat to allow it to run for adjustment purposes.
