I had the same problem when mine arrived. Air was leaking from around the hose. I just Ignored it. A MUCH larger problem happened to me 2 weeks ago. The air hose inside the machine SPLIT! The compressor is set to deliver at 80psi. As I my CNC was cutting, I heard a loud POP, peaked under the the cover of the machine and saw a large split in the hose. I emailed tech support 2 weeks ago (the night that it happened) with pictures and so forth, and asked what my options were of buying a new hose or whatnot but I am yet to get a reply from them. Really starting to irk me that I haven't recieved a reply being I just purchased a mig welder from them a few weeks prior to this. I red-necked it up and wraped it with electrical tape to get me by for now... hardly. The will be hearing from me again soon. I need to work my work around my work's work schedule.
