Replacing Take-Up Spring
If you are getting inconsistent stitch tension or if your thread looks loose and sloppy near the tension
assembly under operation, check your take-up spring (
J
). If the wire hook has broken off, you’ll need
to replace the take-up spring� To do this, disassemble the Upper Tension Assembly� Keep track of
how the parts are removed as they will be replaced in the same manner (
34
)�
1� Pull the cover knob (
C
) straight off (wiggle a
bit if needed)�
2� Unscrew and remove the threaded
knob (
D
)�
3� Remove the big spring (
E
), the spring
holder (
F
), the two tension disks (
G
and
H
),
and the keyway washer with pip (
I
)�
4� Remove the old take-up spring (
J
) by
pulling it straight out�
5� Slide the new take-up spring over the core
post (
K
) so that the pip on the back faces
in toward the machine and the straight arm
of the spring faces down (approximately at
a 6 o’clock position). Push the spring in all
the way�
6� Spin the arm of the spring clockwise past
the slot in the plastic core�
7� While holding the spring arm in place, slide
the keyway washer (
I
) back onto the core
with the pip facing in, so the take-up spring
arm rests on the metal pip of the washer�
8� Replace the first tension disk (
H
) with the
convex side facing out� Add the second
tension disk (
G
) with the concave side
facing out�
9� Replace the spring holder (
F
) with the
concave side facing out and the spring (
E
)�
Screw the threaded knob (
D
) back on the
post and add the cover knob (
C
)�

Proper Needle Orientation
& Installation
When installing a new needle, make sure the
needle is inserted in the correct direction� With
the front of the machine facing you, the scarf or
carved-out area (
A
) of the needle should face to
the right� Push the needle all the way up into the
needle bar, then tighten the needle screw (

)�
