2.10.1 Recommended Needles
The standard needle to use on the Butterfly Embroidery Machine is a 75/11. Different needles
may be recommended for different applications, such as leather work or silk, however generally we
always recommend 75/11
Changing out needle sizes MAY require hook timing changes.
There is a lot to know about needles. We recommend the reader study all about needles before
proceeding. There is a good article at -

2.10.2 Changing or Replacing Needles
When a needle breaks, it is required that you find the broken pieces. If not, the broken shards
can scratch your hook or even lock up the machine entirely. If you cannot find the missing pieces, it is
recommend blowing the entire hook area off with compressed air, in attempts to blow and other pieces
away.

Once you have cleansed the area of any broke needles, the next step it to remove the broken
needle. To change out a broken needle, locate the screw above the needle. Slightly loosen this screw
until the needle can be pulled down. DO NOT loosen this screw too much or the entire needle bar
assembly will come apart. Replace the broke needle with a same sized needle. Ensure that the SCARF of
the needle is towards the back and that the eye of the needle is straight through. You must also ensure
that the lint hole is clean and the needle goes all the way through. If the scarf it not towards the back,
the machine will not run. Likewise, if the eye of the needle is not perfectly straight, you might have
issues.
