Sorry don't know about his particular vice but I can offer some suggestions. First have you gone to Kurt's website they have a few generic PDFs with service and maintenance guides?
Is this a double vice? Well have you removed the moveable jaw? It has a set screw in the back that you remove to pull the jaw off of the mechanism that moves. Inside it has a steel half ball inthere so be careful. The set jaws should unbolt from the bottom of the vice. |
