I need your help guys. I've a Fx 4 stage hand pump for over 7 month now, filling a 480cc up to 250bar, with a lot of fills though it. I want to know what kind of maintenance i have to do to it, particle filter, moisture filtre (i suppose it has silica gel) etc. I don't have any local retrail stores so i have to do it for myself, if you can give me any kind of instructions it would be nice 
Thanks in advance, Manuel
