Either needle can be set closer to or farther from the other
(see Figs. 16 and 17) by loosening nuts (OO) and adjusting
hinge screws (R).
Great care must be taken when making any change of time,
not to make the change too great or carelessly. See that all of
the screws are tightened firmly before starting the machine.

across the bar about IJ inch from its lower end; when the needle

bar so that when it rises inch from its lowest position, the

case down to the eye, the full length of the eye should be seen
below and close up to the point of the hook.
