I was wondering if anyone has had this happen before. I have a vega 2000 AB and I clean it every time I use it. Remove paint jar clean the opening in the bottom with water and q-tips. Run water through the brush then I run windex through the brush, backflush with the windex then get rid of the remaining cleaner in the jar I use. then I put fresh windex in and run more through the brush, then backflush again. Then I clean the jar out and put water again and run the water through. Then I am done cleaning. I used my AB a few times a week for the last couple weeks and it seems to work fine. Trigger nice and easy etc. Yesterday I thought let me pull the needle and just give it a wipe down before I even started painting. I loosen the needle chuck and the needle will not budge. I remove the needle chuck and still the needle will not budge. I was wondering what could cause this? The needle is currently out of the brush but I do not want to say that story. But I will say it was not easy to get out and I need to order a new needle now since mine looks similar to the letter "S" which sucks but... So I want to do whatever I can to avoid this in the future.
