Hook Timing
The Hook Timing adjustment should not change when adjusting the needle depth
position, but it would be a good idea to check it and make sure. Figures 3-5 and 3-6
show the proper hook/needle relationship.
The hook point is not fully
drawn in Figure 3-6, but its
position is indicated. In
order for the hook point to
catch the loop of thread, it
must pass through the
needle scarf area
approximately 1/8"
(3.2mm) above the eye,
when the needle has risen
3/32" (2.4mm).
