1GENERAL INFORMATION
1.1 ABOUT THE MACHINE
The Butterfly B1501B/T is a single head (single station) embroidery machine with 15 needles
(colors). This allows the user to embroider up to one garment at one time with one needle at a time.
The machine automatically color changes (as indicated or preprogrammed by the embroidery machine
design). A color change is in essence selecting a different needle with a different color thread in the
needle. The machine has a USB port (memory stick) that reads several different embroidery formats.
The user manually loads the pre-digitized designs into the machine off of the USB port and/or the
network when applicable.
1.2 COMPATIBLE DESIGN FORMATS
The Butterfly machine work with the following design formats all saved on a standard USB flash
(thumb or memory) drive. Instruction on how to save to these formats can be found in your software
user manual. If you do not have software that will write to one of the compatible formats, please go to
http://www.Threadses.com to download Threads - Free Digitizing / Editing Embroidery Software.
DST (Tajima Format)
EXP (Melco DOS Format)
1.3 TYPE OF EMBROIDERY APPLICATIONS
The Butterfly machine is comparable with most all of the major industrial (commercial)
embroidery machines. Some embroidery equipment may or may not have special equipment attached
to offer additional types of embroidery. The following general list includes several applications where
the Butterfly Embroidery Machine might be used. Typically to change from one type of embroidery
setting to the next requires the operator to manually change out adapters.
This general list includes but is not limited to:
Flat Embroidery Work
oFlat embroidery work typically includes works done when the embroidery
machine tabletop (removable on the Butterfly) is left on the machine. This
refers to anything typically flat in nature or design such as

P a g e | 8

Drapery
Table Cloths
Aprons
Yard goods (yard referring to a measurement of fabric/material)
Etc.
Tubular Embroidery Work
oTubular Embroidery Work typically refers work that is done with the removable
tabletop removed from the machine. This allows for the embroidery work to be
draped down from the machine hanging from the embroidery hoop. Tubular is
currently the most popular form because it makes hooping and embroidering
shirts much easier. Hooping a Tubular Frame is general much less time
consuming and easier than hooping with other types of hoops or frames.
T-Shirt
Polos
Pillow Cases
Bags
Back of Hats
Etc.
Cap (270 degree) Embroidery
oCap embroidery refers to embroidery done directly on a baseball style cap/hat
Baseball Caps
Etc.

2.6 SETTING THE SPOOLS
The Butterfly B1501B/T is a
15-color machine meaning it can hold
up to 15 different spools of thread.
Generally, most users will use 15
different colors of thread designating
at least 6 of the colors for basics such
as white, black, red, blue, green,
yellow, etc. There are various brands
and types of threads. The most
common types are Rayon and
Polyester. Rayon is a softer but
weaker thread. Typically, polyester
(or “poly”) is recommended due to its
strength which also reduces thread
breaks.
Step A –Begin by placing 15 spools of
thread on the thread stand. Refer to
Figure 2-7.
Step B –Take the first spool (1)
thread and pass it through eyelet ‘2’
in the image followed by ‘3’ then ‘4’.
Step C –Take the second spool (5)
thread and pass it through eyelet ‘6’
in the image followed by ‘7’.
Step D - Take the third spool thread
(8) and pass it through eyelet ‘9’ in
the image
Step E –Continue with the next spool
in sequence (to the right of spool 1). Continue till the entire thread rack is threaded.
You can choose to thread the tension knob while threading the thread rack or, wait till the entire thread
rack is threaded and then thread the rest of the machine (proceeding pages).

2.7 THREADING AND TENSIONS OF YOUR MACHINE
Be sure you have already completed the previous sections before proceeding. Proper threading
and tensions of your embroidery machine are essential to production, thread breaks, and final
embroidery quality. Without properly threading your machine and setting the correct tensions per
spool, needle and bobbin, your machine may not run. It is very important that the threading tracks and
tensions are constantly checked.

2.8 SETTING UPPER THREAD
2.8.1 Upper Thread Threading
The upper thread refers
to the thread that is seen on the
top of the embroidered item.
The upper threading track is
shown in Figure 2-8. An upper
thread break typically refers to
when the current spool of thread
that is embroidering has broken.
Upper thread is also physically
located at the top of the machine
whereas the lower thread
(bobbin) is located towards the
bottom. Upper thread is the
common spool of thread used to
embroidery designs.

h?v=DvGlU2_-yLo
Refer to Figure 2-9 to thread.
Step A –First complete
the section “Setting the threads”.
Step 1 –Insert the first
thread into the eyelet of the pretension knob. The pretension knob is the one at the very top of the
machine and is the first tension knob the thread passes through
Step 2 –Place the thread in between the 2 disks of the pretension knob going to the right.
Step 3 –Detach the top of the thread tube and place thread through U-Slot
Step 4/5/6 –For this step you will need the threading rod. The Threading Rod is a narrow piece
of plastic approximately 2 feet long about the width of a pencil tip that comes with the standard tool kit.
If you do not have a threading rod, you can also use a guitar string or anything similar. On the end of the
threading rod, there is a cut out notch. Insert the threading rod from the bottom of the threading tube,
notch end first. Pass the threading rod through the entire threading tube until the notched end comes
out. Attach the thread to the notch and (5) pull the other end of the threading rod back out of the
threading tube so that the thread is completely through the tube. (6) Attach both ends of the threading
tube back onto the machine.
Figure 2-8: Upper Threading Track

Butterfly B1501B/T - Single Head 15 Needle Embroidery Machine Manual
Step 7 –Pass the thread
under the thread guide. The
thread guide is a piece of metal
loosely attached to the machine
by a screw and spring. The
function of the thread guide is to
unravel threads that might still
be raveled and to keep threads
going straight in their designated
paths.
Step 8 –Pass the thread
through the main tension knob in
the same manner as it goes
through the pretension knob
Step 9 –Place thread to
the left of the guide rod
Step 10 –Pass the thread
thru the next guide hook directly
under the tension side. Below
this guide hook is a rotary wheel.
The rotary, or Thread Break wheel, is used to detect thread breaks. If your machine is giving false thread
breaks, first check that this wheel is properly threaded. If this wheel is properly threaded, check the
entire thread track for any mis-threading.
Step 11 –Place the thread to the left and then under the guide pin located directly to the left of
the rotary wheel. Then bring the thread back over the top of the wheel and then to the right, and the
back down and to the left of the next thread guide pin.
Step 12 –Bring the thread down and place thread under the next thread guide.
Step 13 –Open the head case cover. To the right of the machine behind the cover, on the head,
there is a lever that goes up and down. Push the lever down as far as it goes. When you do, you will see
several (12) small wires/springs. These are known as the Check Springs.
Step 14 –Place the thread to the right of the right most cylinder rod where check springs come
out of when the check spring lever is pressed down. Place the thread through the check spring eyelet
from the right to the left. Bring the thread back up to the left of the leftmost rod corresponding to the
current thread you are threading. Move the lever so that the checks springs go back up all the way and
then bring it back down about 1mm to give the springs a little bit more spring than if they were all the
way up. Not placing the check springs in the correct position will cause trimming problems and
problems when changing colors.
Step 15 –Bring the thread back up about 3 inches into the take up lever eyelet.
