1. General Observation of the Front Frame Cover, Mast and Hand Wheel
The following observations, accompanied by
necessary adjustments, will ensure trouble-free
thread passage. Failure at any of these points will
significantly affect thread tension.
Check:
1. The thread mast should be adjusted so that the
eyelet loops are centered directly over the spool
pins .
Note: The thread mast has two little balls that fall
into detents/holes when aligned. These help keep the
eyelet loops aligned over the center of the spool pins.
If a correction is necessary:
Loosen the screw on the
bottom of the thread mast. Make sure both detent
balls are in their locater holes, rotate the entire
thread mast by turning the vertical mast support
until the top eyelet loops are directly over the spool
pins. If the thread mast is too tight inside the bracket,
remove the screw, push the mast out of the bracket
until you can rotate the eyelet loops to be directly
over the pins while the detent balls are in their locater
holes .
Retighten the Phillips head screw firmly into
the bottom of the thread mast support.

Check:
2. Make sure that a gap of 1.0 mm to 3.0 mm exists
between the frame and the hand wheel. (Note:
The hand wheel screw is inside the front cover and
cannot be seen from the outside of the machine,
therefore it can only be adjusted with the front
cover removed.)
If a correction is necessary:
(Usually this would only be necessary if the hand
wheel is rubbing, has an extreme gap or is loose.)
Remove the front cover (see removing front cover),
loosen the hand-wheel set screw, position the hand
wheel and re-tighten the set screw.
