My SP 15 seemed difficult to get into Trip/Print so, after researching similar posts on this site I drew the conclusion that I was missing the flat spring (x23790) and upon inspection, this seemed to be the case. However, now that I have the springs, I am looking at the trip arm assembly and it seems that perhaps I was incorrect. The illustration on sheet no 287-A of the manual shows part x22998 Roller Stud (x3490?) which according to sheet 302 is positioned under the spring, thus providing the tension. My press however is identical to the mechanism shown on sheet No. 248 in which the roller stud is absent and a spring is built into the trip assembly (BRS-2 Spring). So my questions are:
1. Are there 2 variations for the trip assembly? Did they change the design for later presses in order to overcome the broken spring problem?
2. Did I buy springs that I don’t need?
3. Once they are snapped on, can they be removed intact or do you have to chisel them off?
4. Why is it still difficult to get it to switch from Trip/Print?
Many thanks to the smarter brains out there.
