ILLUSTRATIONS
This manual has been arranged to simplify ordering repair parts. Exploded views of various sections of the
mechanism are shown so that the parts may be seen in their actual position in the machine. On the page
opposite the illustration will be found a listing of the parts with their part numbers, description and the number
of pieces required in the particular view being shown.
Numbers in the first column are reference numbers only, and merely indicate the position of the part in the
illustration. The reference number should never be used in ordering parts. Always use the part number listed
in the second column.
Component parts of sub-assemblies which can be furnished for repairs are indicated by indenting their
descriptions under the description of the main sub-assembly. As an example refer to the following text.

When a part is common to all machines covered in this manual, no specific usage will be mentioned in the
description. However, when the parts for the various machines are not the same, the specific usage will be
mentioned in the description and, if necessary, the difference will be shown in the illustration.
*Ref. No. showing no Part No. is for location only. Part is not for sale separately.
A numerical index of all the parts shown in this manual is located at the back. This will facilitate locating the
illustration and description when only a part number is known.
IDENTIFYING PARTS
Where construction permits, each part is stamped with its part number. On some of the smaller parts and on those
where construction does not permit, an identification letter is stamped in to distinguish the part from similar ones.
PLEASE NOTE:Part numbers represent the same part, regardless of which manual they appear. On all
orders
NEEDLES
Each needle has both a type and size number. The type number denotes the kind of shank, point, length, groove,
finish and other details. The size number, stamped on the needle shank, denotes the largest diameter of the blade
measured between the shank and the eye. Collectively, the type number and size number represent the
complete symbol which is given on the label of all needles packed and sold by Union Special.
