Mini Sewing Machine
The Mini Sewing Machine is compact, lightweight and portable. It comes with 102 color spools of
thread, a foot control and a #14 sewing machine needle. This machine takes up very little storage
space and can meet all your basic sewing needs.
INSTRUCTIONS
Setting Up the Mini Sewing Machine
1. With the Mini Sewing Machine facing you, place on a sturdy, flat surface, making sure
it is in the “Off” position. See Figure 1.
SKU 90216 PAGE 3
2. To place batteries in the Mini Sewing Machine, tilt the machine on it’s side as shown
in Figure 2. Remove Battery Door on the underside of the machine and place 4 AA
batteries in the designated positions or you can use a Power Adapter (not provided)
and plug it into the 6V DC jack located on the right side of the machine. Replace
Battery Door.
3. When using the Foot Petal, plug in the Foot Petal Plug on the end of the cord into
the jack under the DC jack and place the Sewing Machine in an upright position.
Place Foot Petal on the floor under your table and within easy reach. Turn the
machine “On”.
Threading the Mini Sewing Machine
1. Place the white plastic Spindle in the Spindle hole located on the top of the Sewing
Machine. Place the Spool of Thread you wish to use on the Spindle. Give the
spool of thread a few turns in order to release at least 8 inches of thread.
See Figure 1. (Continued on next page).

Threading the Mini Sewing Machine (continued)
2. See the 7 positions for threading the Mini Sewing Machine, indicated in Figure 3 below.
Step “F”: Thread needle from front to back in the “eye” of the needle. Then pull thread forward.
Winding the Bobbin
Note: A pre-wound Bobbin is already in place in the Bobbin chamber under the
Presser Foot. This is for demonstration only. You will need to replace it with a full
Bobbin for your sewing project.
1. With the spool of thread on the white plastic Spindle on top of the machine, unwind
the thread approximately 8 inches.
2. Place the Purple Bobbin Pin into the hole in the center of the Hand Wheel and turn it to
lock it in position. See Figures 3 thru 6.
Thread
3. Insert the loose thread from the top Spool of thread into one of the small holes in the
Bobbin. Insert the thread from the inner side to the outer side of the Bobbin and wind
the thread by hand in a counterclockwise fashion for approximately 4 turns.
4. Place the Bobbin onto the Purple Bobbin Pin. See Figure 6.

5. Hold the thread going from the spool of Thread to the Bobbin lightly as shown in Figure 6.
This will prevent tangling. Be sure the machine is in the “On” position. Turn the Hand
Wheel towards you to begin the spin and press the Foot Petal gently. The Bobbin will
begin to fill with thread from the spool of thread. Note: The Needle will be moving up
and down during this step. Keep fingers and objects away from the needle. When
the Bobbin is completely filled with thread, cut the thread and remove the Bobbin and the
Bobbin Pin from the Hand Wheel. Figure 6.

Bottom Treading Instructions with Bobbin
1. Remove the transparent Plastic Cover from the Bobbin Chamber. Slide it away from the
machine but do not remove. See Figure 7.
Bobbin Chamber
2. Move the Needle to the upward position by turning the Hand Wheel towards you.
3. Remove the Black Bobbin Holder and place the metal Bobbin inside. See Figure 8.
The position of the Bobbin’s threading should be in a counterclockwise configuration when
placed in the holder. Note: The loose end of the thread should be hanging to the left of
the Bobbin.
4. Pull the thread out approximately 6 inches.
5. Slide the thread behind the “Notch” in the Bobbin Holder as shown in Figure 9.

6. Place the Bobbin Holder back into the Sewing Machine,
allowing the thread to remain in the Bobbin Chamber
but making sure that the thread is still secure in the
Bobbin Holder “Notch”. Figure 10.
7. The bottom threading is now complete. Top and bottom
threading is critical to the operation of the Mini Sewing
Machine. The machine was pre-threaded correctly at
the factory. If you followed the above directions, it
should mimic the threading done by the factory. If you
find that this is not the case, try again to re-thread the
machine using the previous steps. With practice thread-
ing will become easier.
8. If knotting occurs, try re-threading top and bottom
threading instructions.

Before Stitching Fabric
Step 5: Place on the “Lo” setting for delicate
fabrics. Will help prevent puckering. Use “Hi”
setting for heavy fabrics. See Figure 14.

Step 3: Pull the looped bottom thread
and top thread away from you toward
the rear of the machine. See Figure 13.
Step 4: The machine is ready to use
once the top and bottom threading is
complete and the threads are in the
correct positions.
Thread Tension Adjustment
Tension Adjustment Screw was pre-set at the factory. You can manually adjust tension by
turning the round white plastic “Tension Adjustment Screw” directly above the Presser Foot
and Needle. See Figure 14. Bottom thread tension cannot be adjusted.

Changing Needles
1. Turn the Hand Wheel forward, lifting the Needle to it’s highest position.
2. Loosen the Needle Clamp Screw (Figure 14). Replace a broken or damaged needle.
3. When inserting a new needle be sure the flat side of the needle is facing the Clamp
Screw and push it as far upward as possible. Then tighten the Needle Clamp Screw.
Step 1: Pulling Bobbin thread up
from the bottom to the top of the
machine: Hold the end of the thread
from the top threading step and turn
the Hand Wheel clockwise one
complete turn. See Figure 11.
Top Thread

Step 2: Gently tug the top thread upward,
until the bottom thread is looped up and
out of the machine cavity as shown. See

Beginning to Sewing
1. Position the Mini Sewing Machine on a flat, level surface such as a desk or table.
Sit directly in front of your Mini Sewing Machine. Turn the Hand Wheel toward you
one compete turn so that the needle is in an upward position.
2. Lift the Presser Foot using the Lever located directly above and behind the Presser
Foot. See Figure 15.
3. Place the fabric to be sewn under the Presser Foot and the needle above the area to
be stitched. Lower the Presser Foot. Turn the Hand Wheel one or two turns so needle
has engaged with fabric. With the power switch “On”, gently begin to push down on
the Foot Pedal and sew. The fabric will automatically be pushed forward.
CAUTION: Use your fingers to guide the fabric but keep them away from the needle
while machine is “On”.
4. Start and stop sewing as needed for stitching straight or curved areas. After each stop,
begin sewing again by tuning the Hand Wheel and then using the Foot Pedal. You will
notice, by using the Foot Pedal, you can sew faster. But gauge your speed carefully.
For sewing right angles, stop the Foot Pedal with the needle still in the fabric. Lift the
Lever. Turn (pivot) your fabric to the desired angle. Lower the Lever and begin sewing
again using the Hand Wheel and then the Foot Pedal. Release the Foot Pedal when
the area you wish to stitch is completed.
5. On completion turn Hand Wheel clockwise to lift needle. Lift Presser Foot with Lever
and push your fabric back and away from you. You will note that it is still attached by
the two threads (Bobbin thread and top thread). Cut thread leaving at least four inches
of thread coming from the Sewing Machine. Tie off your threads on your fabric to
prevent raveling. When all sewing is completed, turn “Off’ the Mini Sewing Machine
and store in a safe, dry space, preferably with some kind of cover. Remember this is a
delicate, precise instrument.
Note: Be sure the Sewing Machine is in the “off” position when not in use. This wil prevent
accidently starting the machine with the Foot Pedal. Be sure children are kept away from the
Sewing Machine unless under supervision.
