Changing a Needle
When installing new needles, always use industrial grade needles recommended by Melco for use in
the EMT16.
How to Change a Needle
1. Make sure the safety grabber blade is in the back position before changing a needle. If it is not,
press the Adjustment and Center keys on the EMT16 keypad to move the grabber back.
2. Each needle has a needle clamp set screw that holds it in place.
3. Using a small flat-blade screwdriver, turn the needle clamp set screw counterclockwise about ½
turn, until the needle can slide down and out of the needle bar. Do not loosen too much or re-
move the set screw. Loosen the screw just enough for the needle to be removed.
4. Embroidery needles have a front and a back side. The needle must be installed correctly or
the sewing quality may suffer. If you install the needle incorrectly, you my also get thread
breaks. The front of the needle has a long groove (thread guide), while the back has and
indented notch (scarf).
5. With the thread guide facing forward and the scarf facing back, slide the needle up and
into the needle clamp as far as it will go. The eye of the needle should be turned 5°to the
right. (There is an acceptable range of 0° - 20° to the right)
6. A needle orientation magnet may be used to help determine the angle of the needle eye.
This cylindrical magnet can be temporarily attached to the front of the needle just above
the eye. The end of the magnet will rest on the thread guide and stick out from the needle.
This will better indicate the angle of the eye. For reference, one minute is 6 degrees on a
clock face.
7. Re-tighten the needle clamp set screw to hold the needle in place.
The needle breaks or is bent.
The thread will consistently fray - this usually means there is a bur on the needle causing it to
fray a part of the thread.
The needle is dull.
Sewing conditions change, such as a change in fabric.
