    The guide (P) is used for making a seam parallel with, and
at a certain distance from the edge of the work; it is used only
for straight or convex edges.   (Set it at the reqiiired distance
from the needle and fasten firmly by thumb screw (Q).  It may
be removed entirely if not required for use.
              To on the Machine
          ” The machine should be oiled occasionally with the specially
prepared sewing machine oil soid for this purpose at all Singer
shops; a small drop of oil at the end of a broom splint, or a small
splinter of wood, should be applied at each place where a part of
the mechanism moves through  or.“ against another part while the
machine is in motion.                                                                                 .,
