Industrial sewing device??

I have just gone to my industrial sewing device after standing idle for 6 months. The foot seems to be stuck solid, any thinking on how to free it up?
Answers:
A tiny bit of good quality piece of equipment oil or a teensy squirt of WD40 should do the trick. (If you use either of these, run a speck piece of fabric through the foot for a few minutes {'blind' sewing} so you don't get the residue on the textile you're using.)
