Singer 2809 - Hook Timing (Hook and Needle Synchronism)

Service Manual
Before hook timing is attempted, needle location (page 70-71), needle to hook relationship
(page 72-73) and hook drive belt tension (page 80-81) must be correct.
1. Remove face plate, presser foot, needle, needle plate and bobbin case.
2. Insert a size 18 needle.

position.
5. Observe the position of the center timing mark (A) with relation to the upper needle bar
bushing.
6. Turn the hand wheel toward the front of the machine to bring the lower timing mark (B)
