I just bought this Pfaff 335, I believe old casting. Any help with owner manuals or parts manuals would be greatly appreciated. Also if anyone knows what the largest thread and needle combo that i can run. Currently I'm trying to run 138 thread and 134-35LR Nm 130/21 needle. The needle is a tight fit. I've been watching videos and timed/adjusted needle/hook.
I've had a servo motor put under it but i'm currently looking for a speed reducer also if anyone can point me in the right direction as to which too buy. Thanks
