I have an ancient Gravermeister that has had the adapter kit installed on it so it will have 1600-2400 spm. I got it a couple of months ago and am having some problems with it. I haven't used it over 10 hours since I got it and I hope someone can help me figure out what is wrong. It has been working okay except for the EXTREME heat it produces and I haven't turned it on for over a month. I decided to mess around with it today and it worked for a little while, about 10 minutes, and then wouldn't work any faster than about 1800 spm. I have taken the 915 hand piece apart and cleaned it (it was very gunked up, but no oil in the airline going to the handpiece) and the little can that has the hole in the bottom had a little bit of fluid in it and the other little can had a lot of fluid in it and the filter is hard as a rock. I don't know if the filter is supposed to be like that or not, I washed it with dish soap and hot water and it does look a little better but I cannot blow any air through it (don't do this, it tastes terrible) and is drying for the night. I will put it back together tomorrow. The little jar that has fluid in it on the other side is still a tad over half full. Does anyone have one of these machines and can you give me some advice please?
