Dixon cone drive adjustments

I have seen several threads that ask for the procedure for adjusting Dixon cone drives. but cant seem to find a step by step guide. Does anyone know of a video and/or written instructions that may be accessed online? This is a 1994 42" model.
Mine has unequal response between right/left sides and I am looking for some guidance.

Thank you.
