Various options of application
► Vertical thread unwinding (with or without lubricator)
from normal spool pin or optional multiple spool holder
(Fig. 1-3 )
► radial thread unwinding (with or without lubricator)
(Fig. 4 )
► during the initial threading of the sewing computer and
when the radial thread release is used it is advisable to
pull an extra inch of thread from the spool before the
threader button is pushed (Fig. 5 )
radial thread guide
How to use the thread guide
► it is preferable to replace the standard foam disc with
the foam rotary disc (with white plastic inner part) on
the rear spool pin
The extra thread guide ensures the consistent thread
release, when using threads i.e. metallic, lively or even
wounded thread spools.
► place thread spool on spool pin and guide thread
through thread guide. Then run thread via middle eyelet
of telescopic rod. Continue threading the sewing
computer as normal
► during the initial threading of the sewing computer and
when the radial thread release is used it is advisable to
pull an extra inch of thread from the spool before the
threader button is pushed
Any of the two spool pins (see arrow markings) can be
used. However, it is best to use the rear pin due to its more
favourable unwinding angle. Refrain from using the pin of
the winder.
In order to achieve perfect stitching results, it might be
necessary to reduce the upper-thread tension slightly when
using the radial thread unwinding and depending on the
thread used.
It is absolutely essential to use the
correct foam disc under the thread spool.
