HOW TO LIFT UP THE LOWER THREAD

-This sewing machine lifts up the thread manually, and this is very easily done by taking the following steps:

1. Hold the upper thread with your left hand
2. Using your right hand turn the manual wheel (n° 11) in the direction indicated by the arrows (clockwise) for the needle to make a complete cycle (go down/go up completely) and when the needle is in the lower position it will take up the lower thread and lift it up to the highest position.
   3.Once the needle is in its highest position take hold of the lower thread in your hand and pull both threads (upper and lower) towards the back part of the machine.
3. The sewing machine is now ready to start sewing again.

HOW TO ADJUST THE THREAD TENSION

-If you see that when you are sewing the seams are not tight and the thread knots up frequently, this means that the thread tension must be checked.

-For proper sewing the tension of both the upper and the lower thread must be the same, and there is a dial provided for this purpose (n° 3) to adjust the upper tension more or less required and also to adjust the tension of the lower thread. The lower spool has a screw to adjust the thread tension. Please s

-The thread tension depends on a series of circumstances, on the type of needle, on the type of cloth, on the type of stitch and consequently in order to check the correct thread tension trial stitching must be made and an adjustment made in accordance with the result.
-To know whether the tension is correct, the seam must be like in the following illustration a.

Examples of incorrect thread tension

- Upper thread tension too high (or lower thread too low), image b. - Upper thread tension too low (or lower thread too high), image c

HOW TO LOAD AN EMPTY SPOOL

-When the lower spool no longer has any thread left, you have an automatic option to load it by taking the following steps:

1. Pick up the empty spool and put it on the spool spindle (n° 20)
2. Take hold of the end of the upper bobbin thread in the bobbin peg (n° 14) and thread through the pressure selector (n° 15) until you reach the empty spool which

is located on the spool spindle (n° 20), take hold of the empty spool and wind the thread around the same a couple of times.

1. Finally press the winding button (n° 13) to start to fill the bobbin with thread. When you have reached the amount you require, press the button again (n° 13) to stop and cut the thread

NEEDLE CHANGE

-If the needle breaks you will need to change this to be able to carry on sewing. For this please take the following steps:

1. Disconnect the machine from the mains electricity supply.
2. Lower the presser foot by means of the lever ( n^0 8)
3. Lift the needle up manually to its highest point. To do this turn the manual wheel (n° 11) in the direction indicated by the arrows (clockwise).
4. Turn the needle adjustment screw (n° 5), towards the left and the needle will come out.

5. To put a new needle in place, please make sure that the flat part of the needle is facing the back part of the machine.

6. Take hold of the needle between your thumb and forefinger and push the needle up to the very end.

7. Finally tighten down the adjustment screw (n°5) towards the right to ensure that the needle is fully tight and in place.

REVERSE STITCHING BUTTON

-If you hold this button down the machine will stitch backwards which is ideal for reinforcing seams.

HOW TO SEW ON BUTTONS

-To sew on buttons you will need to put in place the button accessory that is provided (n° 8) which locks down to the lower plate by means of the 3 pivots.

-Once in place you must pull up the lower thread as indicated in previous sections. -Then you put the button that you wish to sew down on the cloth and tack down the button by hand to prevent it from moving.

-Place the cloth with the button underneath the presser foot and select the stitching.

-Lower the presser foot downwards and lower the needle down manually with the manual wheel in order to ensure that the needle coincides with the holes in the

button. Once you have checked that the needle coincides with the two holes in the button, press down the pedal to begin to sew the button on automatically.

-If the button has 4 holes the operation has to be repeated by turning the cloth around 90 degrees.

HOW TO SEW BUTTONHOLES

-To make buttonholes you have to use the stitching indicated below and also the buttonhole presser foot. To do this you have to substitute the normal presser foot with the special buttonhole presser foot. To do this the section HOW TO REMOVE THE PRESSER FOOT has to be followed.

1. To start, please mark the length of the buttonhole on the cloth with a pencil.
2. Put the marked cloth under the presser foot with the buttonhole mark facing you.

3. Move the presser foot slide guide (A) towards you in such a way as the upper mark (B) of the guide coincides with the buttonhole starting mark that has been marked on the cloth.

4. Select the buttonhole stitching with the stitching selector dial and sew forwards until you reach the buttonhole mark.

5. Select the buttonhole stitching with the stitching selector dial and sew 5 or 6 stitches.

6. Select the buttonhole stitching with the stitching selector dial with the backwards stitching button (n° 9) until you reach the back buttonhole mark.

7. Select the buttonhole stitching with the stitching selector dial and sew 5 or 6 stitches.

8. Remove the cloth from the machine and cut the thread.

9. And now in order to open the buttonhole please use the buttonhole cutter as indi-

cated in the following illustration.

CLEANING AND STORAGE

-Your machine requires regular cleaning and lubrication. For satisfactory sewing, a machine which is used for a few hours a day needs to be cleaned and oiled once a month.

IMPORTANT: Disconnect power supply before performing maintenance on the machine. Remove holding cloth and needle. Remove needle plate. Brush off all dust and lint.

-Clean shuttle case with a cleaning brush or soft cloth. Use oil manufactured specially for sewing machine use. Other oil will eventually cause mechanism to jam. Apply one drop of oil on the shuttle where friction occurs.
