Replacing the Reciprocator on the SWF
Compact Series Machine (601C and 1201C)
Installing the new reciprocator
1. Holding the reciprocator upright, guide the pin on the back side into the hole at the
bottom of the connecting rod.
2. Move the assembly slightly to align the guides around the presser foot driving shaft
located to the right.
3. Before inserting the driving shaft back down through the top of the head, notice that the
bottom end has a flat side. (Fig.12) As you insert the shaft, align this side to the left and
keep it facing that direction at all times.
4. Slide the shaft down through the reciprocator, continuing all the way down through the
felt gasket and round bearing at the bottom of the head. It may be necessary to remove
the plate holding the bearing in place to get the shaft to slide easily through the bearing.
(Fig.13)
5. The shaft should slide completely down until the top is flush with the bottom of the
channels cut for the wicks. (Fig.14)
6. Once the shaft is in place, tighten the 2mm screw in the hole at the bottom left of the
head that you loosened in step 2 of removing the broken reciprocator.
7. If you removed the bearing guide plate in step 4 above, replace it now.
8. Using a small screwdriver, press the wicks back down into the driving shaft.
9. Replace the take up lever guide rail. Center the screws in the holes of the rail as close
as possible before tightening.
10. Replace the left and right cover plates. The plates should sit flush on top of the bearing
guide plate you replaced earlier.
Remounting the Needle Case
1. Holding the needle case upright, line up the wiper hook under the head to fit into the
thread holding bracket at the bottom of the needle case. This bracket is just behind the
presser feet on the needle case and lined with a soft, Velcro-like material. The hook end
of the wiper should pass between two pieces of material.
2. Set the lower lip of the needle case (Fig.15) into, or behind the small bearing at the
bottom of the head (Fig.16). Tilt the needle case up, and with light upward pressure, set
the top of the case down onto the take up lever guide rail. If mounted properly, there
should be virtually no movement of the needle case. It may take two or more attempts
to get the needle case to seat properly on top of the head. Tip: use a rubber band to
hold all the take up levers level as you put the needle case back on the head. This will
help to keep them all at the same position during the remount procedure.
