These are trial posts so had to ignore some of my own rules. Sorry for that.
Few yrs back, one of our AMO compact machines pump stopped working. Quote was 25k for visit and then some.
Googled it. Found one post by a african doctor who had posted some guidlines. Opened the machine. There was a loose connection. Tightened it and then put a bit of hot glue over that. Working well since 5 yrs now.
Sorry but dont have photos. Will update once i can .
