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 largest diameter
of blade, measured midway between shank and eye. Collectively, type and size number represent the
complete symbol, which is given on the label of all needles packaged and sold by UNION SPECIAL.

Recommended needle is Type 947GA. It has a round shank, round point, No. 2 bag length, double
groove, spotted, short point, chromium plated, and is available in sizes - 200/080.

Selection of proper needle size is determined by size of thread used. Thread should pass freely through
needle eye in order to produce a good stitch formation.

To have needle orders promptly arid accurately filled, an empty package,a sample needle, or the type
and size number should be forwarded. Use description on label. A complete order would read: “1000
Needles, Type 947GA, Size 200/080”.

THREADING AND OILING DIAGRAM

For 401 stitch, thread machine as indicated above. The looper threading has been enlarged for clarity.

For 101 stitch, thread machine using needle thread only.

The oil has been drained from the machine before shipping and the reservoir must be filled before starting
to operate. Maintain oil level between the two red lines and add oil when oil level drops below the
bottom red line. The machine is automatically lubricated and no oiling other than keeping the main
reservoir filled is necessary. For further lubricating instructions refer to paragraph on “LUBRICATION”.

SAFETY RULES

CAUTION

THIS SAFETY SYMBOL INDICATES YOUR PERSONAL SAFETY IS INVOLVED.

TO PREVENT PERSONAL INJURY:

- All power sources to the machine MUST be TURNED OFF before threading, oiling, adjusting or replacing
parts.

- Wear safety glasses.

- All shields and guards MUST be in position before operating machine.

- DO NOT tamper with safety shields, guards, etc., while machine is in operation.

LUBRICATION

Use a straight mineral oil with a Saybolt viscosity of 90 to 125 seconds at 100 degrees F. This is equivalent
to UNION SPECIAL Specification No. 175.

Before operating, fill machine with oil at plug screw (A, Fig. 2).
While filling machine with oil, check gauge (B). When proper
oil level is reached, the oil level should appear in the center
between the two red lines on gauge (B). It is recommended to
always check oil level before operating to be sure machine is
filled between the lines. CAUTION: DO NOT over fill machine.

To drain oil, remove plug screw, at right, in front, below
handwheel or lower crank chamber cover on back of ma­chine. Oil must be changed every 2000 operating hours to
minimize wear.

On new machines, or a machine out of service for an ex­tended period of time; lubricate machine as follows:

Remove head cover, clean out lint, then directly oil needle bar
link and needle bar. Replace head cover and fill machine with
oil to proper level. Run machine at low RPM to ensure proper
lubrication of components preventing any damage which may
occur from lack of oil distribution.

SYNCHRONIZING LOOPER AND NEEDLE MOTIONS

Synchronization is the most important adjustment
involving the needle and looper motion relation,
because it maintains the needle-looper relation at
both the needle loop taking time, as well as when
the needle enters the looper triangle. This adjust­ment is best made using synchronization gauge set
TT34.

Remove the throat plate, feed dog, looper and
needle thread take-up wire, (also called strike-off
wire). Fig 3 Using gauge set TT34, re-attach the
throat plate (A) to the throat plate support with the
throat plate screws. Insert the pin (B) into the hole
for the looper and tighten with its screw. Turn the
handwheel in operating direction, (towards the
operator), until the pin lightly touches the right
edge of the throat plate. Insert the indicator (C)
into the hole for the needle thread take-up wire,
and move it up or down until the pointer (D) on the
indicator reads at "0", and then tighten the screw.
Now turn the handwheel in opposite of operating
direction (away from the operator), until the pin
again lightly touches the right edge of the plate. If
the machine is synchronized the pointer on the
indicator should again read "0". If the pointer is
above or below the "0", the machine is out of
synchronization. A variation of one line is allowable.

To synchronize the machine the following proce­dure should be followed. Thread screw (F) (99271),
from gauge kit TT34, into the looper drive lever
rocker shaft through the center of the thrust adjust-

Fig 3

"0" (Fig. 3A). Loosen screw (E) in the looper drive lever and pull screw (F), (99271), slightly toward the
operator. Retighten screw (E) in the looper drive lever and recheck the synchronization as outlined
above. Repeat as necessary to obtain proper synchronization.

If pointer on the indicator reads below the "0", (Fig. 3B). Loosen screw (E) in the looper drive lever and tap
screw (F), (99271), slightly away from the operator. Retighten screw (E) in the looper drive lever and
recheck the synchronization as outlined above. Repeat as necessary to obtain proper synchronization.

If synchronization gauge set TT34 is not available, the following procedure can be used.

SYNCHRONIZING LOOPER AND NEEDLE MOTIONS (CONTINUED)

Fig 3B

Turn handwheel in the operating direction until the
point of the looper (A, Fig. 4) moving to the left, is
even with the left side of needle (B). Note the height
of the eye of the needle with respect to the looper
point (See Fig. 4A). Turn the handwheel in the re­verse direction until the point of the looper again
moving to the left, is even with the left side of needle
(See Fig. 4A). If the height of the eye of the needle
with respect to the looper point are the same,
looper and needle motions are synchronized - a
variation of .005 inch (.127mm) is allowable. If the
distance from the eye of the needle to the point of
the looper is greater when the handwheel is turned
in the operating direction, the looper drive lever
rocker shaft will have to be moved slightly towards
the rear. Moving the shaft towards the front acts the

for final setting of needle bar height.

Fig 4A

Fig 5

Adjust looper drive rocker lever shaft as follows:

Loosen screw (C, Fig. 4) in looper drive lever (D). A rod of .146­40 thd. or Union Special Screw No. 99271 can be threaded into
the looper drive lever rocker shaft through the center of thrust
adjusting screw (E). Tap or pull slightly as required to position
shaft for proper synchronization. Tighten screw (C) securely and
remove rod or screw used to position shaft.

Loosen lock nut (F) and TORQUE thrust adjjusting
screw (E) to 6 in. lbs. (7cm/kg); re-tighten lock nut
(F) securely.

With the looper at extreme right end of travel,
check location of the right looper connecting rod
bearing using gauge No. TT35. Place large hole of
gauge over threaded stud (A, Fig. 5). The left end
of gauge should locate against the RIGHT side of
looper rocker cone (B). If adjustment is necessary,
loosen clamp screw (C) and reposition looper drive
lever (D) as required, then tighten screw (C).

If gauge is not available, check setting with a
scale. Distance between the centerline of rocker
cone and centerline of looper drive lever stud
should be 4 1/16 inch (103.2mm) as shown in Fig. 5
when looper is at its extreme right end of travel.

LOOPER AND LOOPER NEEDLE GUARD SETTINGS

Insert a new needle, type and size specified. Looper
gauge is 5/32 inch (4.Omm) which is the distance from
point of looper (A, Fig. 6) to centerline of needle (B)
when looper is at extreme right end of its travel. Looper
gauge No. 21225-5/32 (C) is available for this setting.
Adjustment can be made by loosening nut (D),(it has a
left hand thread) and nut (E); turn connecting rod (F) as
required to attain specified dimension. Hold connecting
rod in position and tighten nut (E), then nut (D). NOTE: Be
sure that the left ball joint is in a vertical position and
does not bind after adjustment.

Fig 6

While turning handwheel in operating direction and the looper (A, Fig. 7) moves to the
left, its point should be set to pass the rear of the needle (B) with .003" to .005" (.08 to
.13mm) clearance. Adjustment can be made by loosening screw (G, Fig. 6), turn stop
screw (H) clockwise to move looper towards the rear, counterclockwise acts the
reverse. It is suggested to hold looper towards the front while making this adjustment.
Tighten screw (G) after adjustment has been made and recheck movement of
looper.

Fig 7

Looper needle guard (attached to looper), 56100Z28B only, should be set with the
looper point set to the centerline of the needle, set front guard 0.005" to 0.010" (0.13
to 0.25 mm) away from looper.

NEEDLE BAR HEIGHT

Turn handwheel to position point of looper (A, Fig. 8) 0.20" (0.5mm) past the left
side of needle (B). At this time the top of the eye of the needle (B) should be
even with the under side of the looper (A). To make adjustment, loosen screw (C
Fig. 15) and move needle bar (A) up or down as required.

SETTING 101 STITCH RETAINER

56100Z30B & 56100Z31B

The 101 stitch retainer is used to hold open the needle loop as the looper moves
to the right so that the needle can enter the loop to form the 101 stitch. To set
the retainer.

Remove the throat plate and set the retainer (A, Fig 9) so that the tip is
approximately 3/32” (2.4mm) from the front of the needle hole in the throat plate
and tighten screw (B). The retainer may need to be move in or out slightly if
skipping or malformed stitches occur while sewing.

Fig 8

Attach the throat plate and looper/spreader to the machine. Turn the
handwheel in operating direction until the looper moving to the right is directly
under the tip of the retainer (Fig. 9A). Adjust the retainer tip up or down with
screw (C, Fig 9B) so that there is .003” to .005” (0.10mm to 0.13mm) clearance
between the top of the looper/spreader and the bottom tip of the retainer and
then tighten screw (C).

Fig 9A

Fig 9B

Fig 9

Feed dog (A, Fig. 10) should be centered in throat plate (B)with
equal clearance on all sides and ends with feed travel set to
desired stitch length. At highest point of travel, tips of feed dog
teeth should extend the depth of 3/64" above throat plate and
parallel to same. Screw (C) should be set to support feed dog
after screw (D) has been loosened which secures feed dog in
position.

Parallel adjustment can be made by loosening nut (A, Fig. 11) and
turn screw (B) clockwise to lower front of feed dog, counterclock­wise acts the reverse. When properly set, retighten nut (A).

Right to left adjustment can be made by loosening screws (G, Fig.

12) and slightly move feed rocker (H) on feed rocker shaft (J) as

required, then retighten screws. Check to ensure that feed rocker
arm (K) does not bind after adjustment.
Forward or rearward centering of feed dog can be accomplished
by loosening nuts (L, Fig. 12), move feed rocker (H) as required and
retighten nut.

FEED DOG SETTINGS

SETTING THE UPPER FEED DOG

Set the up upper feed dog so at it lowest position the teeth will just con­tact the lower feed dog teeth (A, Fig 10A). To make this adjustment,
loosen nut (C) and turn screw (B) up or down as required. Lock nut (C)
after adjustment has been made.
Note: It may be necessary to raise the upper feed dog for thick materials
or if tearing of the tape occurs.

Fig 10A

SETTING THE UPPER FEED DOG LIFT LEVER

With the upper feed dog at its lowest position, set the lift lever so the there
is approximately 1/32” clearance between the top of the lift lever and the
bottom of the feed dog heel. (D, Fig 10A) To make this adjustment loosen
screw (E) and move the lift lever up or down as required.

Fig 11

CHANGING STITCH LENGTH

Set the stitch to required length.This is
accomplished by loosening lock nut
(A, Fig.12) 1/2 turn, (it has a left hand
thread) on the end of the stitch
regulating stud and turning stitch
adjusting screw (B) located under the
left end of the cloth plate in the head
of the mainshaft (C), which is marked
with “L” and “S”. Turning the screw in
a clockwise direction shortens the
stitch (moves stitch regulating stud
toward the “S”) and turning it in a
counterclockwise direction lengthens
the stitch (moves stitch regulator stud
toward the “L”). Retighten the lock
nut securely. To prevent destructive
damage to the feed drive bearing,
key screw (D) must engage the “U”
shaped key slot in ferrule (E).

LUBRICATING FEED BAR SHAFT

Fig 12

Grease fittings have been added to
both ends of feed bar shaft (F, Fig 12).
It is advisable to add #2 bearing
grease at these points every month
using grease gun AS60-187. A can of
grease can be ordered under part
number GR18.

REAR NEEDLE GUARD

Rotate handwheel in operating direction to position
looper point to just enter the scarf of needle. At this time
the needle guard (A, Fig 13) should be at its extreme end
of forward travel. Set the guard front to back as close as
possible without touching the needle. Guard should be
set as low as possible, yet have its vertical face ap­proach above the needle point 1/32" +1/64" (0.8mm
+0.4mm). To move the needle guard forward or back­ward, loosen the screw (B), move needle guard as
required, and retighten screw. To raise or lower needle
guard, loosen screw (B), and turn screw (C) clockwise to
lower needle guard or counterclockwise to raise it.
Retighten screw (B) after guard is properly set.

NOTE: Any change in stitch length will require a
change in rear needle guard setting.

THREADING

Draw looper and needle threads into the machine and start
operating on a piece of fabric. Refer to threading diagram
(Fig. 1) for manner of threading this machine.

LOOPER THREAD CAST-OFF WIRE

Looper thread cast-off wire (A, Fig. 14) located on the take-up
shield (B) controls the amount of slack thread in the system
and can be moved to any position. It should be set laterally so
that it is midway between the two discs of take-up (C) and the
tip parallel with the discs.

It is usually set toward the take-up to almost the limit of its slot
so that it barely clears the highest point of the take-up. The
height and lateral adjustment of the retainer affects the
control of looper thread as looper moves to the left. Ordi­narily it will be set in approximately a horizontal position. More
looper thread is given to the stitch when the retainer is raised
and set towards the take-up. However, if the retainer is raised
too high, the looper thread triangle may be wiped under the
blade of the looper, causing traingle skips or pulled down
stitches. This can be checked by observing the action of the
looper thread as the looper moves to the left.

THREAD TENSIONS

Fig 14

Tension on the needle thread should be only sufficient to produce
uniform stitches on the under surface of the fabric. Tension on the
looper thread should be just sufficient to steady the thread.

PRESSER BAR HEIGHT

Height of presser bar (D, Fig. 15) is set correctly if it is possible to
remove the presser foot when the foot lifter lever, located at the
back of the machine and extending above the upper crank
chamber cover is fully actuated (pulled to the right). There should
be approximately 1/16 inch (1.6mm) clearance between lower
surface of the presser bar connection and guide (E) and bottom
surface of head opening in the bed when foot lifter lever is re­leased and presser foot lying flat on the throat plate with feed dog
below throat plate.

Adjustment can be made by turning handwheel to position needle
bar at bottom of stroke. Loosen screw (F) and while holding
presser foot down on throat plate, position presser bar connection
and guide as required to attain specified clearance and retighten
screw.

PRESSER FOOT PRESSURE

Regulate the presser spring regulating screw (A, Fig. 16) so that it
exerts only enough pressure on the presser foot to feed the work
uniformly when a slight tension is placed on the fabric. Turning it
clockwise increases the pressure, counterclockwise acts the
reverse.

SETTING NEEDLE THREAD GUIDE AND FRAME EYELET

For 56100Z28B Turn handwheel in operating direction until the needle bar
reaches its lowest position. Set needle thread take-up wire (B, Fig. 16 so
that its thread contact surface is even with the center of the needle bar
thread eyelet (C). Lower this setting for a smaller needle thread loop, raise
for a larger loop. Set needle thread frame eyelet (D) so that it is approxi­mately 3/4 inch (19.1mm) above centerline of its attaching screw (Fig. 16).

For 56100Z30B & Z31B Set the needle thread take-up wire (E, Fig 16A) to
the lowest position. Set needle thread frame eyelet, (F) so that the screw
is centered in the eyelet slot. Set the needle thread frame eyelet, lower,
(G) so that the screw is just left of the center of the eyelet slot.

ORDERING REPAIR PARTS

ILLUSTRATIONS

This catalog 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, descriptions 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 that part in
the illustration. Reference numbers 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. Example:

48 2910 5AK Crank Assembly, looper driving lever ........................................................... 1

49 22587K Screw, bearing cap ,(upper) ............................................................ 2

50 56343C Guide, ball joint ................................................................................

1

51 56343E Splasher, oil ....................................................................................... 1

52 22559A Screw, bearingcap (lower) ............................................................... 2

It will be noted in the above example that the eccentric, ball stud, and bearing are not listed. The reason
is that replacement of these parts individually is not recommended, so the complete sub-assembly should
be ordered.

At the back of the book will be found a numerical index of all the parts shown in this book. This will facili­tate locating the illustration and description when only the part number is known.

IDENTIFYING PARTS

Where the 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 simil’ar ones.

Part numbers represent the same part, regardless of catalog in which they appear.

IMPORTANT! ON ALL ORDERS, PLEASE INCLUDE PART NAME AND STYLE OF MACHINE FOR WHICH PART IS
ORDERED.

USE GENUINE REPAIR PARTS

Success in the operation of these machines can be secured only with genuine UNION SPECIAL repair
parts as furnished by the Union Special Corporation, its subsidiaries and authorized distributors. They are
designed according to the most approved scientific principles, and are made with utmost precision.
Maximum efficiency and durability are assured.
