Instructions for Operating the Machines
Raise the presser foot (B, Fig. 3) by means of
the presser bar lifter (C, Fig 3) to prevent
injury to the foot (B, Fig. 3) and feed (A, Fig.
3).
FIG 3. FRONT VIEW OF THE MACHINE
It is necessary to understand the stop motion
(E, Fig. 3) by which the balance wheel (D,
Fig. 3) can be released when required, thus
enabling the operator to become proficient in
the use of the treadle and permitting the
winding of bobbins without running the stitch-
ing mechanism. It also allows the operator to
wind bobbins without removing partially sewn
work and without unthreading the machine.
To release the balance wheel (D, Fig. 3), turn
the stop motion screw (E, Fig. 3) over toward
you. It will be necessary to hold the balance
wheel while loosening the stop motion screw.
After releasing the balance wheel, place your
feet upon the treadle and with the right hand
turn the balance wheel over toward you. This
will start the band wheel, treadle and pitman,
the sewing mechanism having been discon-
nected.
Continue the motion thus begun by an alter-
nate pressure of heel and toe, until a regular
and easy movement is acquired, and the bal-
ance wheel kept in continuous rotation by use
of the feet alone.
When you are thoroughly familiar with the
treadle movement and can restart the
machine without turning the balance wheel in
the wrong direction, tighten the stop motion
screw to connect the balance wheel with the
stitching mechanism.
Place a piece of cloth under the presser foot,
let the foot down upon it, and operate the
machine in this way without being threaded,
until you have become accustomed to guiding
the material.
