INTRODUCTION
Model and Serial Numbers
The contents of this manual must be understood by the user to ensure that the correct
part for the correct machine model is selected.
Some equipment built by Melco containing the same "common" name may be identified
by more than one model part number. In some cases, a different serial number sequence
is also prevalent between two models of the same machine.
Determine the model number of your machine before you use this manual to order parts.
The machine MODEL number is located on the label that is placed on the front of the
frame, under the table and to right side of the machine.
Remember, although many parts are identical between the various embroidery peripheral
models, this manual should only be used for identifying and ordering parts for the
machines described above.
How To Use This Manual
The manual is divided into several sections, each containing a set of parts most common
to each other, or to a function of the machine.
Figures
Accompanying each section is a figure showing the general area of the machine that is
represented in that section. Parts are identified with letters and numbers in these figures.
Letters contained in circles generally are used to refer the user to a different figure or section of the manual that identifies the assembly with more detail. Part numbers and part
identifications of the numbers inside circles are found on the pages adjacent to the figure.
Item Numbers
All the numbers in circles on a diagram are listed in the first column of the parts listing
accompanying that figure. Each item number in each figure is identified independently in
hopes to help prevent any confusion that may occur by trying to "cross-reference" part
numbers.
Part Numbers
The Melco part number is found in the second column of the parts list, directly in line
with each item number from the first column.

110278-01, Rev. E Illustrated Parts Manual
Part Descriptions
Each part listed has a descriptive name in the third column of the parts listing. Hardware
(such as screws, washers, etc.) are described by size in order to help the user to identify
common hardware items that can be obtained by local sources if desired.
Special Parts Handling
If care is not taken in handling certain parts of the sewing head, there is a high probability
that the sewing head will not function properly or the parts will fail prematurely.
These parts are to have special handling considerations from the vendor, through quality
control inspection, into spare parts inventories, then on to packaging for shipping, and
finally to installation.
Handling of these parts (and for that matter all parts), is not limited to the considerations
below. Please use common sense, good judgement, and accepted handling practices in
handling all parts. If you have any questions or concerns, please call your area service
department.
General Considerations
* Painted and coated surfaces need to be protected from dirt, other foreign matter,
nicks, and scratches.
* Non-painted and coated surfaces must not be touched by the human hand, to pre-
vent corrosive body oils, dirt, and other foreign matter from contaminating the surfaces.
* Protect all bearings, bushings, cams, rails, gears, rollers, needle bars, pins, studs,
connecting rods, guide shafts, and other surface finishes from dirt, other foreign
matter, marring, scratches, and nicks, etc.
* Bearing surfaces and shaft bore surfaces need to be thoroughly cleaned and mat-
ing parts oiled before assembly.
Printed Circuit Boards
Printed circuit boards are packaged and shipped in anti static bags. The components of
the printed circuit boards are sensitive to static electrical discharges. The use of standard
anti static precautions is recommended.

Special Packaging
Several parts are packaged in specially sealed packages. These packages keep lubricant on
the parts and protect them from contamination during shipment. To install these parts,
clean your hands and place a small amount of sewing machine oil on your fingers to kept
the integrity of the part intact.
Index
Hardware not listed can be found by identifying a related part and refering to that page.
CAUTION: When purchasing hardware from a source other than Melco,
it is the user's responsibility to ensure that such hardware is of sufficient quality and grade to meet or exceed Melco's original equipment
hardware. Melco assumes no liability for the use of inadequate hardware that was purchased by and/or installed by other than an authorized Melco factory representative.
