Hi there. I got a T20 recently. Along with the machine came a few springs which I am not quite certain of their usages. No manual whatsoever came with the machine. I emailed Dirk a couple of times asking about their usage but did not get any reply whatsoever. Last enquiry was made during early September. So, I was just wondering if any fellow Superstringer stringing machine owners can shed some light on their purposes and usages? Having only the Klippermate before this, please do pardon me if these are very common spare parts. Also, as a side query, does the Superstringer machines supposingly come with some form of manuals? Thanks in advance.
