Bracket Positioning
When attaching the jump stitch solenoid and bracket, it is not only necessary to
place the plunger correctly, but you must also position the assembly in the proper
forward to backward relationship. There are three concerns in positioning the
solenoid and bracket assembly:
Bracket
Position 1
The solenoid and bracket assembly should be far enough forward so the plunger
will cause the reciprocator to rotate enough to release the needle bar during the
jump stitch cycle.
Bracket
Position 2
The solenoid and bracket assembly must not be so far forward that it causes the
reciprocator to rotate to its mechanical rotational limit. This may cause premature
failure of the reciprocator mechanism.
Bracket
Position 3
The solenoid and bracket assembly must not be so far backward that it contacts the
embroidery head connecting rod during its mechanical motion.
To position the solenoid and bracket:
1. Put the new solenoid and bracket assembly in place and push it to the back of
the cutout in the side of the head.
2. Attach it to the embroidery head with the 2 screws removed earlier, then check
the alignment to be within the above 3 positions. Be sure that the plunger
contacts the reciprocator mechanism, that the mechanism works properly, and
that the jump stitch assembly does not contact the embroidery head connecting
rod during its mechanical motion.
