I was at ArtEngine the other day and noticed that the laser lens was dirty when I went to use it. I had to use about 5 q-tips so it must have been really dirty smoke from a previous cut.
When I ran it after cleaning it I noticed the room was getting smokey so I pulled the pre-filter from the cleaner and sure enough it was pretty clogged. I couldn’t find another so I replaced it and stopped work. I guess I will eventually go looking for the manuals and start to figure out the air cleaner. I know it was expensive so I will read up on it before figuring out how to service it. The pre-filter obviously needs a hardware store part.
Also, lately I’ve noticed that the air cleaner is chirping sometimes. I’ll have to look that up. I suspect it has too much drag since it needs some service.
