prevent an unauthorized person from
changing stitch length.
To remove the plunger, first remove the top cover.
Then remove the retaining ring near the tip of the
plunger,
allowing
the
plunger

be
withdrawn.
The
hole in the top cover should then be filled by inserting
a plug screw 140607, which can be obtained at an
additional charge. Replace top cover.
