Hey there, if your fork has play in lockout, it's air in the cartridge. To get rid of it, get it serviced. If you don't it will slowly get worse till you have no lockout, and no rebound damping.fumi said:
Pressure? Keep an eye on feel. If it's good, roll with it. Soft, air it up. If it goes soft in a week or two (or less), get it serviced.
When you are locked out, you have no more need of rebound than you would on a chromo or carbon rigid fork:idea:
