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rst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 (B)�
