Just about to pull the springs out of my Ohlins forks to see just what I have, but wondering about this special tool the factory manual refers to, I assume to engage the (2) pin holes in the top cap:

Can I use a generic adjustable spanner (adjustable pin spacing) to turn the top cap off, or should I opt for something like the factory tool?
