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.
