To adjust the thread take-up spring tension:
Lower the presser feet to relieve pressure on the
tension assembly. Loosen the tension stud set
screw (
A
), turn tension stud (
B
) clockwise with a
screwdriver (
C
) inserted in the split shaft end to
provide more spring tension, or counterclockwise
to decrease tension. After adjustment, tighten
the tension stud set screw (
A
)
while pushing the
tension stud in so that it is seated fully as it was
before loosening (
Figure 100
).
Note:
To make this adjustment it is often
necessary to remove the whole tension
assembly from the machine to gain access to
screw (
A
). Remove by loosening set screw (
I
)
(page 54) then pull out the assembly. Make
sure to notice the insertion depth of the tension
assembly core before doing this. When done,
the core should be reset to the same depth.
To set spring tension as it was originally
set by Sailrite:
Loosen set screw (
A
) first and
then turn the tension stud (
B
) counterclockwise
to reduce the tension of thread take-up spring
(
D
) to zero. From here, turn the tension stud
(
B
) clockwise until the spring (
D
) just comes
into contact with the end of the slot on the
thread take-up spring regulator. Then, further
turn tension stud (
B
) clockwise by 3/8". After
adjustment, tighten tension stud set screw (
A
).
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.
