FEED CAM TIMING

2. If you need to adjust the feed cam timing lay the machine on
it’s back and locate the feed cam and loosen the two hex set
screws with a 2.5mm hex tool and turn the cam until the feed
dogs do not move. Re-tighten the hex set screws.

1. In order to check feed cam timing
for proper sewing, remove the foot,
turn the stitch length dial to 6. Bring
the needle to the highest position.
Start to lower the needle and stop a
little below 17.5mm, (top line). At this
point (between 17.3

– 17.5mm) the

feed dogs should not move when you
push up and down on the reverse
lever.

(Note: this has a very fine or

small adjustment window)

27

Do not gauge on top of the
feed dogs, make sure you are
gauging off the needle plate
for the 17.5mm!
