How to charge works triple rate shocks

[glowpowered]

The front shocks on my R bottom out all the time when i jump. They are works triple rates. I assume what ever was in them leaked out over the years. I noticed the schrader valves on them. Can i charge them up?

what kind of adjustment do they have? do they have rezzies?
