My HQ Avante is only two months old and I have done five wall hangings on it (not an excessive amount of quilting). It has developed some very loud and disturbing squeaks when the Prostitcher levers are lowered. When I lift them up, the squeaks go away. (I have cleaned the wheels and the track.) It sounds to me as if something needs to be oiled in the undercarriage, but I have seen no instructions about oiling anything in the carriage. What can I do to make these noises go away? Should I be concerned and not use my machine? My dealer lives hundreds of miles away and her hands-on experience with the PS is limited, so I can't really get help from her on this type of problem.
Also, when I was quilting a quilt with the PS engaged, I wanted to use a SPI of 9, but the machine kept changing itself back to 11--not immediately, but at some point after I changed it. I would again change it and maybe it would stay at 9 for a few minutes, but then it would be back at 11. Is there a reason it does that? Are patterns programmed with a default SPI? Does my machine have a problem?
