off its shaft, slip the fork of the wheel puller
under
the
projecting
rim of

puli (Fig. 18),
Consult the diagram on the feed
gear
housing (Fig, 18) to
see
how the feed
gears
have
to be exchanged to obtain the stitch length group and stitch length desired. Exchange
the
feed

accordingly.
For better Identification, the
outside
of the feed

onto
its shaft,

that
the
key on
the
shaft

the
notch in
the
feed
gear
and
that
the
mating
gears
are
meshed
properly.
