6. Adjusting
the
thread
tension (Fig.28)
Adjusting the thread tension of this machine is exactly like a conventional lockstitching
machine. Please follow the procedures as outlined in the INSTRUCTION BOOK on DDL-552, 553
and 555, DLN-4I5, DLU-450 or DLD-432. However, please note
that
due to the thread trimmer
attached
to
this
machine,
the
adjustment
is
little
different
than
other
lockstitch
machines.
