Changing A Spool On A Threaded Machine - Pfaff hobbylock 4752 Instruction Manual

Before the machine leaves the factory,
threads are already threaded and their ends
are cut off. Tie one of these thread ends to
the thread from a spool with an overhand
knot, raise the presser foot and pull the new
threads through the loopers. In order to
thread the needle threads, pull the thread
ends through until the knots reach the
needle eye. Cut the threads on both sides
of the knots. Rethread the eye of the needle
with the needle threading aid (see Pages 16,
18). With this procedure, you can save a
great deal of time when threading.
If the threads are not threaded in the machi-
ne, thread the upper looper thread (red) first,
then the lower looper thread (yellow), the
left needle thread (blue) and finally the right
needle thread (green). Two threading dia-
grams are located behind the looper cover
to help you correctly thread the machine.
Threads that are threaded incorrectly will
lead to irregular (skipped) stitches, broken
needles and uneven thread tension. There-
fore always make sure that all the threads
are perfectly threaded before beginning to
sew.
In order to replace spools, cut the threads
between the thread guides and the thread
guide plate. Thread the new threads in the
manner described opposite.
In order to make threading easier, set the
thread tension to "0". After threading, reset
the thread tension to the desired number
(see Pages 30, 31).
