F. THREAD CUTTER BUTTON
Press this button after sewing to cut the upper and
bobbin threads.
The machine will cut both threads automatically.
CAUTION
1. Do not press this button when there is no fabric
in the machine or no need to cut the threads.
The thread may tangle, resulting in damage.
2. Do not use this button when cutting thread
thicker than #30, nylon thread or other
speciality threads.
In this case, use the thread cutter (H).
3. Do not use the thread cutter button when
sewing with a twin needle or a hemstitching
(wing) needle.
G.DROP FEED LEVER
The feed dogs project up through the needle plate,
directly below the presser foot. Their function is to
move the fabric being sewn. The drop feed lever
controls the feed dogs.
For ordinary sewing, move the lever to the right.
This raises feed dogs to their highest position. For
most sewing, the lever should be in this position.
For darning or free motion embroidery or
whenever fabric is to be moved by hand, move the
lever to the left to lower the feed dogs.
Note:
After sewing with the feed dogs lowered, push the
Drop Feed Lever back to the right to resume
sewing with feed dogs engaged. Push the lever to
the right and then turn the handwheel toward you
one full revolution. This will re-engage the feed
dogs.
H.THREAD CUTTER
Use this cutter if the thread cutter button is not
used.
1. Raise the presser foot and bring fabric and
threads backward after sewing.
2. Hook the threads to the thread cutter from back
to front.
3. Pull fabric and cut threads.
I. PRESSURE REGULATOR
The pressure on the presser foot is determined by
the weight of fabric.
To increase the pressure, turn dial to 3.
To decrease the pressure, turn dial to 1.
For ordinary sewing, turn dial to 2.
J. TOP COVER
To open the top cover, lift up the left side of the
cover.
K.HAND WHEEL
By turning the hand wheel, the needle will raise or
lower. You should always turn hand wheel toward
you.
