This shows how to adjust the timing for a PFAFF 335, YAMATA 335 and SPEEDWAY 335. It can be used for all cylinder arm machines since they basically all work the same.
Always be sure to keep your hands away from the needle when making adjustments to prevent injuries. Turn machine off when adjusting.
If your timing is good, do not try to fine tune it. The timing must be precisely adjusted. Machine damage can occur if not done properly. Do not attempt this if you have no mechanical skills or the proper tools. Secure all small parts so you do not lose them.
