Hello, I'm brand new to this site and am by all senses of the word, a beginner wood burner. I bought the HI300 pretty much due to price. I work for a company that sells them so got it at cost... Anyway. I noticed when doing the dollar in the door trick and noticed the bottom gasket is VERY loose.. took the hinge apart and removed a couple washers to tighten the seal per owner manual instructions... Still no good. Any ideas ad to what else I can try? I appreciate any ideas in advance.
