TO OIL THE MACHINE
Use "TYPE B" or "TYPE D" OIL sold only by Singer
Sewing Machine Company. For description of oils, see inside of
front cover. Oil should be regularly used on any surface of metal
which comes in movable contact with another surface.
It is necessary for the easy running of the machine, that all
bearings be oiled. The hook especially should have the attention
of the operator, as a drop of oil occasionally on the bobbin case
base flange prevents excessive friction in the hook race and
assists in making the opening between the stop on the bobbin
case and that on the throat plate; thus, preventing the upper
thread from breaking.
TO SET THE NEEDLES
Turn the balance wheel toward you, to raise the needle bar
to its highest position; hold the needle with the flat side of the
shank toward the other needle (or center), push it up in the
needle holder as far as it can go and tighten the pinch screw.
Care must be taken to set the needles so that they will swing
freely, with their points completely housed, into the grooves of
the piercer on the inside vibration, to assure clear openings.
