Thanks guys... Jeez I tried everything except the vice grips and heating... won't come off. I guess I'll just need to try some stronger measures but I'm guessing the company doesn't suggest lubricating because it shouldn't need it like Cheyenne????

Any ideas on maintenance folks?

Also the different machine colors different throw lengths?? This company makes great machines but the documentation is horrid I wonder if we could find the Chinese website and translate...
