Mayline Futur-matic (Drafting table) w/ Varitask base

Greetings all!,  I have a Mayline Futur-matic (drafting desk)  w/ motorized Varitask base.  Need a manual or instructions for disassembly.so I can replace the huge original desktop (about 48" x 42") w/ one that'll fit my room.  the springs for adjustment are likely too strong for the smaller desktop & I don't want to risk injury taking it apart.  Thanks in advance for any assist!  [images from ebay]
