Needle Precautions; Checking The Needle; Bobbin Precautions - Brother PR-620 Operation Manual

Needle precautions

Be sure to observe the following precautions concerning the correct choice of needle for your machine.
CAUTION
●
Your machine is designed to use household embroidery needles. The factory recommended
needle is "HAX 130 EBBR" (Organ). Schmetz needles 130/705 H-E may be used as a
substitute. Use of any other needles may break the needle or thread or damage the needle-
threading mechanism or result in injuries.
●
Never use bent needles. Bent needles can easily break, possibly resulting in injuries.

Checking the needle

Sewing with a bent needle is extremely dangerous since the needle may break while the machine is being
operated.
Place the flat side of the needle on a flat surface and check that the distance between the needle and the flat
surface is even. If the needle is bent or the tip of the needle is broken, replace the needle with a new one. (Refer
to "Changing the Needle" on page 63.)

Bobbin precautions

Be sure to observe the following precautions concerning the bobbin.
CAUTION
●
Only use prewound bobbin (COATS "L" type/TRU-SEW POLYESTER "Filaments") or bobbins
designed specifically for this machine. Use of any other bobbin may result in injuries or
damage to the machine.
●
Use a bobbin thread that has been correctly wound, otherwise the needle may break or the
thread tension will be incorrect.
●
When winding a bobbin, only use optional bobbin winder (refer to page 188) and metal
bobbins (Parts Code: 100376-053).
●
When winding the bobbin, be sure to use cotton or spun polyester bobbin thread (between 74
dtex/2 and 100 dtex/2).
