Positioning Of The Tension Mechanism In Relation To The Hole In The Arm - Necchi Supernova Instructions Manual

- Positioning of the tension mechanism in relation to the hole in the
arm.
It is very important to check whether the position of the tension me-
chanism in relation to the hole in the machine arm is correct. Here is
the procedure to follow for this adjustment:
Set the presser bar lever No. 20095 in its intermediate position
(embroidery position), as shown in Fig. 64, and check whether the
following requirements are met:
The disc opening rod (release rod) " B " (Fig. 68) is as close as
possible to disc opening lever " N ", however without touching it.
The thread take-up spring (check spring) can move freely without
rubbing against the machine arm (Fig. 69). Distance " a " (Fig.
69) must be about 1/16".
If an adjustment is needed, loosen screw No. 048050 GEB (Fig. 69)
and move the whole tension mechanism along its axis (do not rotate
it) until the requirements under paragraphs 1) and 2) are met. Then
tighten screw No. 048050 GEB firmly.
