Greetings from snowy Colorado. I think this is the machine I have on my frame. I luckily have not had any problems with mine (haven't really used it that much). I will read my instructions to see if i can find somthing that might help. Have you contacted the dealer you bought it from? They should be able to help.
I've had 2 arabs, 5 qtrs and 2 paints. Don't have on right now (miss my babies!!!) Have fun here!!
