CHANGING STITCH LENGTH (CONTINUED)
When packing bearings, parts must
be clean and grease should be
applied directly from the tube to
avoid contamination. Tube of
grease can be ordered under part
No. 28604 P. Greased bearings are
located at (N, M, Fig. 11). If grease
sealed bearings are replaced, they
should be pressed in flush with the
casting. To assemble, start tapered
end of shafts first, twisting slightly
when entering the grease seals to
prevent damage. Check for proper
adjustment of feed dog as de-
scribed under the “Feed Dog
Settings”. Also check to see that
there is no binding at any point.

raise or lower needle guard, loosen screw (B), and turn screw (C)
clockwise to lower needle guard or counterclockwise to raise it.
Retighten screw (B) after guard is properly set.

Any change in stitch length will require a change in rear
needle guard setting.
