Removing covers continued
Remove the screws on the bottom covers for open arm machines.
Fig. A. locating all of the screws may be tricky but when they are all
removed the covers should come off easily. Remove the covers and
check for thread or lint caught in any parts.
For flat bed machines simply lay the machine on its back to check it.
Remove the bobbin case and hook. Fig. B. Check all parts of the
hook for burrs. If you have to polish any from the hook be very careful
to lightly polish and do not damage it. The hook must be smooth or
the thread will get caught. After you check the hook make sure there
is no thread caught around the hook. Remove any you find.
