Feed dog
44 Service Instructions 867 - 04.0 - 10/2019
Important
The higher the feed dog lift, the deeper the feed dog plunges into the
throat plate and may damage the thread-pulling knife or the hook tip.
Making sure that the feed dog lift is not set too high is particularly important
on machines with a short thread cutter (setting in the + range) in order
to keep the thread-pulling knife from sustaining damage.
7. Check the setting.
• Position the feed dog at top bottom center
• Slide a sheet of paper between feed dog and thread-pulling knife
If the sheet of paper can be slid effortlessly between feed dog and
thread-pulling knife, the feed dog lift is set correctly.
If the sheet of paper cannot be slid or is crushed between feed dog
and thread-pulling knife, the feed dog lift must be reduced.
