SETTING THE NEEDLE

Fig. 3

Fig. 4

See Fig. 3. Raise the needle bar A to its highest

point, turning wheel toward you by hand.

Then loosen the needle clamp screw B and the

needle can be inserted into clamp C. Place needle

(flat side to right) in the needle clamp and push it

Flat surface of needle shank

upward as far as it will go into the needle clamp hole, tightening the needle clamp screw securely with a screw driver.

After changing the needle make one complete revolution of the balance wheel by hand to be sure the needle is in the correct position.

WINDING THE BOBBIN

Disengage the hand wheel (5, (Fig. 4) from the stitching mechanism by turning the clutch 6 toward you or counterclock wise.

Place a spool of thread on one of the spool pins, lead thread through the upper thread guide on the arm, and down through the tension disc (10, (Fig. 5) at the base of the machine. Run

end of thread through a hole in the bobbin edge and place

bobbin B on spindle of bobbin winder 7, fitting the notch on bobbin over small pin on spindle. Push bobbin winder pulley against hand wheel. Hold thread end loosely and start machine slowly.

Bobbin will stop winding when it is filled. Turn clutch away

from you until sewing mechanism is again engaged so that

needle moves when you turn the hand wheel.

Break off loose thread end used to start the winding.

THREADING THE BOBBIN CASE

Step 1 (illustrated in Fig. 6). Hold bobbin case between thumb and fore finger of left hand, so that the slot in the edge of the bobbin case is on top. Take the bobbin between thumb and forefinger of right hand so that the thread on top leads from left to right. Step 2. Insert bobbin into bobbin case, pull the thread into the slot of the bob bin case as shown in Fig. 7, and draw it under the tension spring and into the fork-shaped opening of the spring as shown in Fig. 8.
