3. Remove by loosening the set screw (A),
then pull out the assembly.
4. Loosen the tension stud set screw (B);
turn tension stud (C) clockwise with a
screwdriver inserted in the split shaft
end to provide more spring tension or
counterclockwise to decrease tension. After
adjustment, tighten the tension stud set
screw (B) while pushing the tension stud
in so that it is seated fully as it was before
loosening (60).
To set spring tension as it was originally set
by Sailrite: Loosen set screw (B) first and then
turn the tension stud (C) counterclockwise to
reduce the tension of thread take-up spring (D)
to zero. From here, turn the tension stud (C)
clockwise until the spring (D) just comes into
contact with the opposite end of the slot on the
thread take-up spring regulator. Then, further
turn tension stud (C) clockwise by 3/8 inch. After
adjustment, tighten tension stud set screw (B).
The thread take-up spring was properly adjusted
before the machine was shipped. Readjustment
is needed only in the case of sewing special
materials or thread.
