Sewing preparation
Thread-Guide-and-Lubricating Unit
As a thread-guide eyelet (Fig. 1)
Use the unit without lubricator for a controlled guiding of the thread into the
pretensioner, e.g. when using lively thread types.
As a thread lubricator (Fig. 2)
Using the lubricator is advisable when using e.g. threads with high function
values, metallic threads, loosely twisted thread types etc. The silicone fluid
improves the threads‘ gliding properties considerably and therefore helps to
produce flawless stitching results.
Assembly
⦁
insert the unit into the spool-holder cover fixture and push down entirely
(Fig. 1)
⦁
insert the lubricator into the holder on the left side of the unit, taking care to
place the lubricator in such way that the openings for the thread are in line
with the thread flow or thread direction (Fig. 2)
⦁
moisten the felt, add a few drops of silicone fluid
⦁
place the thread spool onto the middle or rear spool pin as usual. Then
guide the thread through the respective eyelet of the telescopic rod and the
eyelet of the thread-guide-and-lubricating unit
⦁
hold the thread with both hands, pull it in to the slit of the felt, pulling it
down as far as it goes so that it‘ll stay in the felt during machine operation
(Fig. 3)
⦁
continue and complete threading the sewing computer as normal
⦁
take care that the felt remains moistened. It mustn‘t dry out. Apply some
drops of silicone fluid once in a while to keep it moist
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. 4).
When using the Thread-Guide-and-Lubrification Unit and depending on the
type of thread used it might be necessary to reduce the upper-thread tension
slightly to achieve perfect stitching results.
⦁
to remove the Thread-Guide-and-Lubrification Unit, push the entire unit up
⦁
Reattach the Thread-Guide-and-Lubrification Unit. Thread the sewing
computer as usual, including the eyelet of the unit (Fig. 2).
ATTENTION!
The silicone fluid must ONLY be used for thread lubrication.
Never use it to lubricate the hook system!
