Anyone still running an SX3?

I need to recommision mine after leaving it standing for 2yrs & since then I have lost almost all my documents.

WD40 or way oil seems to have solidified under the table & in the ballscrews & I'm having trouble knocking off the end plates to slide the table off. Can anyone be so kind to clarify exactly what needs undoing. There is a circlip on the left plate, does this need to come off?

I'm whacking it with a mallet & nothing seems to be moving.
