Replacing the Take-Up Spring
(#533211)
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 (H). 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 (49)�
1� Pull the cover knob (A) straight off (wiggle a bit if
needed)�
2� Unscrew and remove the threaded
knob (
B)�
3� Remove the big spring (
C), the spring holder (D), the
two tension disks (E and F), and the keyway washer
with pip (G)�
4� Remove the old take-up spring (
H) by pulling it straight
out�
5� Slide the new take-up spring over the core post
(
I) 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 (G) 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 (
F) with the convex side
facing out� Add the second tension disk (E) with the
concave side facing out�
9� Replace the spring holder (
D) with the concave side
facing out and the spring (C)� Screw the threaded
knob (B) back on the post and add the cover knob

Material Surface Is Being Damaged
Surface marring is damage to leather and other delicate material
surfaces� To avoid marring, reduce the amount of pressure down
on the presser feet by nearly unthreading the presser regulating
thumbscrew from the machine (50)� See “Adjusting Presser Foot
Tension” (p� 25)�
