PLEASE NOTE:
The needle assortment includes 1 x blue shank needle (no. 11/75), 2 x no. 11/75 needles and 2 x no. 14/90 needles. For optimal sewing results, it is recommend using Organ needles.
Fabric and Needle Chart
Use a needle size of 11/75 or 14/90 for general sewing work.
A fine thread and a fine needle must be used to sew lightweight fabric to prevent damage to the fabric.
Heavy fabric requires a needle large enough to pierce the fabric without the needle thread fraying.
Always test the needle size on a spare section of the fabric you will be using for sewing.
In general, use the same thread for the needle and the bobbin.
PLEASE NOTE:
Use a blue shank needle (available separately) when sewing flexible fabrics, very fine fabrics and synthetic fabrics. The blue shank needle effec­tively prevents skipped stitches.

Setting Spool Pins
The spool pins are used for holding the spool of thread in order to feed thread to the machine.
To use, pull up the spool pin. Push down for storage.
PLEASE NOTE:
When using thread which has tendency to tangle around spool pin, thread through the hole of spool pin as shown. The hole should face the thread spool.
