Choosing a Needle
Choosing the appropriate needle for the job being run is extremely important to the success of
the embroidery. Different fabrics and threads will determine what needle should be used.
General Guidelines
Ball Point needles are commonly used on knits. The idea behind this is for the slightly round-
ed tip of the needle to move the threads of the material out of the way. Common knit garments include T-shirts and sweatshirts.
Sharp point needles are sharper than ball points and are generally used on tightly woven
goods. Some good examples of tighter weaves would include canvas, denim, and twill.
Combination points (SES or RG types) are a good choice for most fabrics and keep needle
changes to a minimum. This saves on labor costs.
Titanium coated needles create less friction and heat when moving through a material. They
are a good choice for sewing on coated fabrics or embroidering with adhesive backings.
Smaller needles can clean up the appearance of small lettering and fine details.
Larger needles create larger holes which can help prevent thread breaks due to friction
when sewing an abrasive materials like a cotton duck jacket.

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 remove 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.
