THREADING THE MACHINE—CONTINUED
4. Thread bobbin case.
A. With bobbin and bobbin case being held as shown, and with approximately 5-6”
of thread for feeding, insert bobbin into case (Figure 4).
B. Pull thread through slot in the bobbin case (Figure 5). Thread should unwind
counterclockwise towards slot.
C. Continue by pulling thread under tension spring and up through slot in spring
(Figure 6).
D. Put thread through hole in bobbin case arm leaving approximately 5-6” of bob-
bin thread hanging from the arm.
Note:
To check for proper thread feed tension, see Thread Tension section.
5. Install bobbin case.
A. Lift and grasp bobbin case latch and with the arm aligned with the notch in the
shuttle race cover, slide the bobbin case fully onto the center post (Figure 3).
You should hear it “click” into place. During this step, it is helpful to hold the
thread with the bobbin case to prevent the bobbin from dropping out of the
case.
B. Trim the bobbin thread to approximately 2”.
6. Replace needle if needed.
Note:
Proper needle type for your machine will be indicated by packet of needles in-
cluded in kit. The binders are equipped with a Schmetz #23 heavy-duty needle. As an
option, the Schmetz #22 can be used. The main difference is the #23 needle is slightly
larger in diameter, therefore stiffer and tends to deflect less. Needle-to-hook spacing
may change and the adjustment should be checked per the adjustment instruction
sheet. The diameter decrease will result in a smaller penetration hole in the fabric.
A. To remove needle, rotate the handwheel towards you (counterclockwise) until
the needle reaches its highest point. Using a 5/64” Allen wrench (provided),
loosen the set screw above the needle and remove the needle.
B. To replace needle, grasp needle with tweezers and position needle with the
long groove facing left and the notch (scarf) facing right. Feed the point into the
needle bar foot, and then the other end up into the needle bar assembly body.
Ensure needle is completely inserted before tightening set screw. You should
not feel needle below foot of assembly when needle is at its highest point. DO
NOT OVER TIGHTEN!
