ILLUSTRATIONS (CONT.)
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 please include part number, name and style of machine for which the part was ordered.
For optimum performance use only genuine Union Special replacement parts.
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
S p e c i a l .
