is
done
to

clearance
between
the
margin stop
and
the margin
stop

margin stop will
set
accurately
when
the
stop is slid
to
the
right
against
the
margin stop latch on the
carrier.
NOTE: Machines equipped with an old style margin
rack
use an
eccentric
plate
mounted on
the
right
end
of
the
margin. rack
to
control
the
rest position
of
the
rack.
Use
the same procedure
indicated
above
to
obtain
the
.001"
to
.005"
clearance
between
the
margin stop and
the
stop latch on
the
carri
er.
