FOREWORD
Th e pr e dom i nant idea behind ~ is to build the best industrial
se wing ma c hin es in the world. The new high speed. streamlined. vertical hook.
needle feed lockstitch machines are a decided achievement along these lines.
All parts are made to precision gauges insuring complete interchangeability.
A few of the outstanding new features are:
1. STREAMLINED DESIGN
Pleasing in appearance. this functional design provides greater stability
and ruggedness. freedom from difficult-to-clean recesses; new neutral
taupe finish is more restful to the eyes.
2. SIMPLIFIED OILING
Lubrication of these machines is automatic with the exception of three
oil holes in upper arm. (See diagram. Fig. 1.)
3. FLEXIBLE COUPLING
Maximum gear life is produced by the flexible coupling located in the
lower main shaft.
4. PERMANENT HOOK TIMING
After the hook has been timed according to factory procedure. and the
hook shaft gear retaining screws secured, hook may be removed and
replaced without further attention to setting and timing.
5. RAPID ACCELERATION
Precision methods in the manufacture of component parts makes
possible top operating speed almost instantaneous.
It is our constant aim to furnish concisely prepared information that will
enable the customers to procure all possible advantages from the use of Union
Specials. The following pages illustrate and describe parts for styles in
Classes 61800. 62200.
ADJUSTING INSTRUCTIONS for MECHANICS coverin g the 61800 C. D and

IDENTIFICATION OF MACHINES
Each Union Special machine is identified by a Style number which is stamped
into the name plate.
Machines similar in construction are designated by a Class number which
contains no letters. Letters suffixed to the Class number indicate the individual
Standard machine style. Letter "Z", however, is reserved as a suffix to the
Standard style identification to specify machine is of Special construction.
APPLICATION OF CATALOG
This catalog applies specifically to the Standard style of machine as listed
herein. It can also be applied with discretion to some Special machines in
this Class.. References to direction such as right, left, front, back, etc .• are
given from the operator's position while seated at the machine.
IDENTIFYING PARTS
Where construction permits, each Union Special part is stamped with its
catalog number. A part too small for its complete catalog stamping is identified
by a letter symbol which distinguishes it from another part similar in
appearance.
Each part nulilber represents the same part regardless of catalog in which
it appears.
IMPORTANT! ON ALL ORDERS, PLEASE INCLUDE PART NAME AND
STYLE OF MACHINE FOR WHICH PART IS ORDERED.
TERMS
Prices are strictly net cash and are subject to change without notice. All
shipments are forwarded at the buyer's risk f. o. b. shipping point. Parcel
Post shipments are insured unless otherwise directed. A charge is made to
cover the postage and insurance.
NEEDLES
Each Union Special needle has both a type number and a size number. The
type number denotes the kind of a shank, point, length, groove, finish, and
other details. The size number, stamped on the needle shank, denotes the
largest diameter of the blade measured in thousandths of an inch midway
between the shank and the eye. Collectively, type number and size number
represent the complete symbol.
Selection of proper r1eedle size should be determined by the size of the
thread used. Thread should pass freely through the needle eye in order to
produce a good stitch formation.
For best results, use only genuine Union Special needles in the op e ration
of this machine. They are packaged under our brand name, ~
which is backed by a reputation for producing highest quality needles for more
than three-quarters of a century.

Basically, Classes 61800 and 62200 are the same except Class 61800 is a
single needle while the Class 62200 is a two needle; therefore, all parts for
the standard machine are the same. In some cases, the quantity requirement
is changed. Special plates near the back of this revised edition give separate
and complete lists of sewing parts applicable to Styles 61800 c. 61800 D,
61800 H, 62200 G, 62200 H.
Near the back of this catalog is a numerical index of parts. Listed are
part and page numbers where components are shown for accurate and complete
description.

OILING INSTRUCTIONS
There are three oil reservoirs on the Class
62200 machines which are filled through the oil
cups "C", "D" and "E" (Fig. 1). Each hook is
automatically lubricated from its own reservoir
by a spiral oil screw. The amount of oil re-
quired for each hook may be adjusted for by a
metering screw located at the bottom of the
reservoir. The ma in reservoir which houses
the gears, stitch regulating mechanism, needle
feed driving mechanism, upper main shaft
bearing etc., lubricates these parts by a splash
action and also supplies oil to the lower feed
mechanism through the lower shaft.
The level of the oil in the three main re-
servoirs can readily be observed at the lucite
gauges "F" ,· "G'' and "H". The manually oiled
holes "A", "B" and "J" lubricate the head
mechanism, the left upper main shaft bearing,
and needle bar frame pivot pin, respectively. Fig. 1
Use a straight mineral oil of a Say bolt viscosity of 200 to 250 seconds at 100° Fahrenheit
for all oiling places. Lubricate machine at points "A", "B" and
11
J" twice daily, depending
on operating conditions, and add oil to cuos "C", "D" and "E" to maintain levels between
lines of the sight gauges "F", "G" and "H

'.
CAUTION! The main reservoir and hook reservoirs (or reservoir) is drained be f ore
the machine is shipped and must be filled before starting to operate.
The oiling for Class 61800 is the same as for Class 62200, except there is only one
hook reservoir.
THREADING INSTRUCTIONS
THREADING THE NEEDLES

WINDING THE BOBBIN
Thread th e bobbin winder by leadin g the thread
from the supply down through the eyelet (A, Fig.
4), down between the tension discs, and underthe
tension post. Press an empty bobbin on the winder
shaft (B) up to the stop, wind the end of th r ead
around the bobbin a few turns in a clockwise di-
rection and press downwardly on hand lever (C)
until pulley is moved into contact with machine
belt, and is locked in that position. When the ma-
chine is operated, the bobbin will be rotated and
filled until the thread engages the automatic throw-
out member, which disengages the pulley. The
extent to which the bobbin is filled can be varied
by the regulating screw (D).
Fig. 4
The tension post bracket is mounted on the winder base, and can be shifted
from left to right by loosening screw (E) so that any tendency of the bobbin to
wind unevenly may be readily corrected.
The purpose of the bobbin winder is to assure the operator a full bobbin at
all times. When the bobbin in the machine is used up, replace it with a full
one and begin to wind the empty bobbinimmediately. Bobbins can be rewound
while machine is sewing.
INSERTING THE BOBBIN
Place the bobbins in the hooks so that
they unwind in th e opposite direction to
that of the hook rotation (Fig. 5). Pull
the thr e ads i nto the slots of the bobbin
cases (A). This operation will bring the
bobbin threads between the tension
s prings and th e bobbin cases. Adjust bob-
bin thread tension, by regulating the
pressure on spring (B) with screw (C) on
bothbobbincase s , sothatthereisa slight
drag on th e thr e ad. Make sure that the
bobbin thr e ad is between the tension
sprin g and bobbin case.

ADJUSTING INSTRUCTIONS FOR MECHANICS
CHECKING THE F LOW OF OIL FROM THE HOOK SHAFTS
Oil is filter ed to the hook shafts from the oil reservoirs. All of the hook
opener mechanisms are maintained in pe ak operative condition by runnin g in
oil. Daily checks for adequate oil supply in the reservoirs are important.
