BALANCE WHEEL STOP MOTION.
This device allows the balance wheel to run free, so that bobbins
may be wound and the correct method of treadling acquired,
without operating the stitching mechanism. To loosen the wheel,
hold it with the left hand, and with the right hand pull out the disc
sufficiently to allow of its being turned either to the right or left,
thus liberating the projection on the inner side of the disc from its
recess.
To lock the balance wheel, hold it with the left hand and, with
the right, turn the disc until the projection springs back into its
recess.
TO ENSURE PERFECT ACTION OF THE MACHINE.
The balance wheel must always turn from the top towards
you.
The presser foot must be raised, except when sewing.
Do not work the machine with the shuttle and the needle
threaded, except when sewing.
The slides (33) over the shuttle must be closed before starting
to work the machine.
TO OPERATE THE TREADLE MACHINE.
Loosen the balance wheel as described above, place both feet
upon the treadle and turn the balance wheel over towards you.
