IDENTIFICATION OF MACHINES

Each UNION SPECIAL machine is identified by a Style number which is stamped into the name plate on the machine. Style numbers are classified as Standard and Special. Standard Style numbers have one or more letters suffixed but never contain the letter "Z". Example: "Style 39800 CA". Special Style numbers contain the letter "Z". When only minor changes are made in a standard machine, a "Z" is suffixed to the Standard Style number. Example: "Style 39800 CAZ".

Styles of machines similar in construction are grouped under a class number which differs from the style number in that it contains no letters. Example: "Class 39800".

The distance between the rows of stitches or between the needles is represented by a gauge number measured in 1/64ths of an inch (.40 mm), going from left to right. The width of overedge is represented by a fraction. Collectively, the gauge number and the width of overedge represent the machine gauge. Example: "5-1/8". Thus, 5-1/8 gauge represents a distance of 5/64 inch (1.98 mm) between the left needle (401 stitch) and the right needle (503 or 504 stitch) and the 1/8 inch (3.18 mm) represents the width of overedge to the right of the right hand needle.

APPLICATION OF CATALOG

This catalog applies specifically to the Standard Styles of machines as listed herein. It can also be applied with discretion to some Special Styles of machines in this class. Reference to direction, such as right, left, front, back, etc., are given from the operator's position while seated at the machine. Operating direction of handwheel is away from operator.

SPEED RECOMMENDATION

These machines have been tested in their complete stitch range at their maximum rated speeds. Varied field conditions, severity and cleanliness of the sewing operation may necessitate operating at a lower speed. When operating from 50-100% machine running cycle and a longer than recommended stitch length, it may be necessary to reduce the machine's speed by 10-15%.

The 39800 is a precision manufactured and tested sewing machine. To obtain maximum preformance, the machine should be operated at 1000 R.P.M. below maximum recommended speed for the first 20 days of field operation. This will minimize readjustment of precision mechanisms.

OILING

CAUTION! Oil was drained from machine when shipped, so reservoir must be filled before beginning to operate. Oil capacity of Class 39800 is six ounces (180 ml). A straight mineral oil of a Saybolt viscosity of 90 to 125 seconds at 100° Fahrenheit should be used.

Machine is filled with oil at spring cap under the top cover. On later model machines, an oil filler fitting has been provided in the back side of the bed casting, located directly in front of the lower overedge looper thread tension post nut. Oil level is checked at sight gauge on front of machine. Red bulb on oil level indicator should show between gauge lines when machine is stationary.

Machine is automatically lubricated. No oiling is necessary, other than keeping main reservoir filled. Check oil daily before the morning start; add oil as required.

To maintain maximum recommended speed and serviceability of this equipment when operating continuously, the oil must be changed at least every six months. In no case should oil remain in the machine for more than one year.

"AIR KLIPP" is a registered trademark of Union Special Corporation.

OILING (Continued)

The oil drain plug screw is located at back of machine near bottom edge of base. It is a magnetic screw designed to accumulate possible foreign materials which may have entered the crank case. It should be removed and cleaned periodically.

NEEDLES

Each UNION SPECIAL 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 in thousandths of an inch, midway between shank and eye. Collectively, type number and size number represent the complete symbol which is given on the label of all needles packaged and sold by Union Special.

Two straight needles of the same length are used in these machines. The recommended needles are Type 120 GS, Size 080/032 for Styles 39800 CA, CB (5-1/8 gauge); Size 090/036 for Styles 39800 CA, CB (12-3/16 gauge), 39800 CP, CQ (5-1/8 gauge) and all 8-3/16 gauge machines. Type 120 GAS, Size 125/049 is recommended for all 12-3/16 gauge machines, except Styles 39800 CA and CB. Type 120 GS is a round shank, round point, set point, extra short, double groove, struck groove, ball eye, spotted, rounded scarf, with a 3/64 inch (1.19 mm) radius at scarf, chromium plated needle and is available in sizes 075/029, 080/032, 090/036, 100/040, 110/044, 125/049, and 140/054. Type 120 GAS is the same as Type 120 GS, except it has a modified point; available in sizes 110/044, 125/049 and 140/054.

Other useable needles are Type 120 GFS which is the same as Type 120 GS, except it has a reduced eye and groove; available in sizes 110/044 and 125/049.

Type 120 GHS is the same as Type 120 GS, except it has a thin ball point, available in same sizes.

Type 120 GKS is the same as Type 120 GS, except it has an oversize ball eye; available in sizes 075/029, 080/032, 090/036, 100/040 and 110/044.

To have needle orders promptly and accurately filled, an empty package, a sample needle, or type and size number should be forwarded. Use description on label. A complete order would read: "1000 Needles, Type 120 GS, Size 080/032".

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

Success in the operation of UNION SPECIAL machines can be secured only by use of needles packaged under our brand name, UnionSpecial®, which is backed by a reputation for producing highest quality needles in materials and workmanship for more than three-quarters of a century.

THREADING

Thread from thread stand (C, Fig. 2 or 2A) is threaded through the upper holes of tension thread guide (D) from front to back and then through the lower holes from back to front: NOTE: Thread No. 2 (401 looper - blue color code) is threaded through the upper hole of tension thread guide (D) from back to front and down through tension post thread bar eyelet (E). All other threads continue between the tension dics (L), through tension post slot (M) in tension post (J) and on through its proper hole in front thread guide (P).

It will simplify the threading of these machines to follow the recommended sequence as designated by the numbers assigned to each thread, starting with thread No. 1, then No. 2, etc. The various eyelets and guides on the machine for each thread have been color coded to further aid the threading process.

Thus, the threading sequence for Styles 39800 CA, CP, CX, VCP, VCX, (503 stitch) is as follows; Thread No. 1, lower looper thread - golden beige color code; thread No. 2, 401 looper thread - blue color code; thread No. 3, overedge needle thread - green color code; thread No. 4, 401 needle thread - red color code.

The threading sequence for Styles 39800 CB, CQ, CY, VCQ, VCY, (504 stitch) is as follows; Thread No. 1, 504 lower looper thread - golden beige color code; thread No. 2, 401 looper thread - blue color code; thread No. 3, 504 upper looper thread - black color code; thread No. 4, overedge needle thread - green color code; thread No. 5, 401 needle thread - red color code.

Before beginning to thread, swing cloth plate open, turn handwheel in operating direction until the needles (R, Fig. 2 or 2A) are at their highest position, release pressure on presser foot by turning presser foot release lever (A), and swing presser arm (B) out of position.

THREADING LOWER LOOPER (Golden Beige Color Code)

Turn handwheel until the point of lower looper (S) is all the way to the right. Use threading wire #39899 A (Fig. 2 or 2A) by inserting into the left end of tube (T) and push through same; through the inside of take-up wires (U) passing over and/or in front of cast-off blade (V) and through long tube (W) until the threading wire protrudes out of same in front of the front thread guide (P). Hook lower looper thread (No. 1) into the threading wire and pull back until the thread comes out of the left end of tube (T). Turn handwheel until the lower looper (S) is at its extreme left positon; then thread lower looper through its left eye, entering from the rear and through the right eye, entering from the front.

THREADING 401 LOOPER (Blue Color Code)

Double end of 401 looper thread (No. 2) and feed same from right to left through thread tube (X) or use threading wire #39899 A in reverse manner; thread through tension thread eyelet (Y) from back to front passing between tension discs around the bottom of tension post, then continuing forward to the cast-off support plate (Z). Thread through adjustable eyelets (AA) from left to right passing under cast-off wire (AB) and over the take-up, under thread guide wires (AC), through pigtail eyelet (AD) from left to right and up through eyelet on shank of looper (AE). Insert doubled end of thread into right eye of looper (AE) from right to left, pushing through approximately an inch or so of thread. Holding tweezers in left hand, insert doubled end of thread into left eye, from front to back, using about 3/16 inch (4.76 mm) projection of thread from point of tweezers. DO NOT THREAD LOOPER WITH NEEDLE LOOP AROUND LOOPER. REMOVE LOOP, OTHERWISE MACHINE WILL NOT SEW.

THREAD UPPER LOOPER (Black Color Code)

Turn handwheel until point of upper looper (AF) is all the way left. Double end of upper looper thread (No. 3 on Styles 39800 CB, CQ, CY, VCQ, VCY) and lead the thread through the auxiliary looper thread eyelet (AG) from back to front and then through both eyes of the upper looper thread eyelet (AH) from left to right; passing through the inside of the LEFT take-up wire (U) and in front of the RIGHT take-wire.

After pulling up the upper looper thread tube assembly (AJ), lead thread down through tube assembly and pull thread out bottom of tube. Push tube down and insert the thread through the eye of the upper looper (AF) from front to back.

THREADING OVEREDGE NEEDLE (Green Color Code)

Pass the overedge needle thread (No. 3 on Styles 39800 CA, CP, CX, VCP, VCX; No. 4 on Styles 39800 CB, CQ, CY, VCQ, VCY) through the right eye of needle thread frame eyelet (AK) from back to front, through both eyes of needle thread pull-off eyelet (AL) from right to left, passing in front of needle thread cam pull-off (AM) and down through the right eyelet on needle head, finally through the eye of the right needle (R) from front to back.

THREADING 401 NEEDLE (Red Color Code)

Pass the 401 needle thread (No. 4 on Styles 39800 CA, CP, CX, VCP, VCX; No. 5 on Styles 39800 CB, CQ, CY, VCQ, VCY) through the left eye of needle thread frame eyelet (AK) from back to front, down through both eyes of needle thread pull-off eyelet (AN) from right to left, passing in front of needle thread cam pull-off, (AP) up through needle thread adjustable eyelet (AR) from right to left, and down through both holes in top eyelet (AS) on needle head from back to front, down through lower eyelet on left side of needle head, then finally through the eye of the left needle (R) from front to back.

THREAD TENSION

The amount of tension on the needle and looper threads is regulated by the knurled tension nuts (F, Fig 2 or 2A). Tension on the threads should be only enough to secure proper stitch formation. Using a postal scale, the measurements are taken with the needles at the top of their stroke and pulled in the direction as indicated. As a start, the approximate tensions should be as follows:

401 needle thread; 2 to 2 1/2 oz. (56.70 to 70.87 gr) straight out of lower eyelet on left side of needle head.

Overedge needle thread; 1 1/2 to 2 oz. (42.52 to 56.70 gr) straight out of lower eyelet on right side of needle head.

Lower looper thread; 1 to 1 1/2 oz. (28.35 to 42.52 gr) straight out of left end of thread tube (T. Fig. 2 or 2A).

Upper looper thread; 1 to 1 1/2 oz. (28.35 to 42.52 gr) straight out bottom of thread tube assembly (AJ. Fig. 2A).

401 looper thread; 1 to 1 1/2 oz. (28.35 to 42.52 gr) straight out of eye at point of looper (AE, Fig. 2 or 2A)

Further refinement of thread tension adjustments will be required to suit a particular seam, thread or material and is discussed at the conclusion of the adjusting instructions.

PRESSER FOOT PRESSURE

Sufficient pressure to feed work uniformly should be maintained. Should it be necessary to increase or decrease amount of pressure on presser foot, loosen lock nut (A, Fig. 3) and turn the adjusting screw (B). Adjusting screw has a right hand thread so tightening increases the pressure, loosening decreases pressure. When pressure adjusting screw (B) has been properly set, tighten lock nut (A) against adjusting screw (B). With presser foot resting on the throat plate, position locking nut (C) so that its under surface is approximately 1/32 to 1/16 inch (.79 to 1.59 mm) from the top surface of adjusting screw (B). Set the cap (D) against the locking nut (C).

FEED ECCENTRICS

Fig. 3

Feed eccentrics used in these machines have been selected to produce approximately 10 stitches per inch (2.5 mm per stitch) on Styles 39800 CA, CB (all gauges), 39800 CP, CQ, (5 1/8 gauge); and 8 stitches per inch (3.2 mm per stitch) on Styles 39800 CP, CQ, CX, CY, VCP, VCQ, VCX, VCY (8-3/16 or 12-3/16 gauge) machines. It will be noted that part number 39540 B-9 or 39540 B-10 are the main and differential feed eccentrics for machines producing 10 stitches per inch, while 39540 B-8 are the main and differential feed eccentrics for machines producing 8 stitches per inch.

Minor numbers of the part symbol indicate approximately the number of stitches obtainable when using that eccentric. Unless otherwise specified, machine will be shipped with eccentrics as stated in previous paragraph.

Generally speaking, differential (right hand) feed eccentric determines the number of stitches produced; the main (left hand) feed eccentric is selected in relation to the degree and direction of stretch of material being sewn, or the type of operation.

The following stitch number feed eccentricities are available under No. 39540 B; 45, 6, 7, 8, 9, 10, 11, 12, 13, 14. Only two eccentricities are supplied with each machine. Additional eccentricities may be ordered separately. To order an eccentricity, use No. 39540 B with a minor number suffixed to indicate number of stitches desired. Example: "39540 B-10".

ASSEMBLING AND ADJUSTING SEWING PARTS

Before assembling and adjusting sewing parts, remove cloth plate, fabric guard chip guard, upper knife assembly, lower knife holder assembly, then follow this suggested sequence.

CLOTH PLATE REMOVAL AND ASSEMBLY

CAUTION! When removing the cloth plate (A, Fig. 4) loosen the cloth plate stud locking screw (B) and lift up cloth plate with the cloth plate stud (C) and cloth plate screw (D) assembled.

In assembly, the cloth plate screw and the cloth plate stud are tightened to the point of removing all play and yet turn in cloth plate. The cloth plate is then assembled to the machine with the flat and "V" slot of the cloth plate stud (C) towards the rear. Stud locking screw (B) is tightened securely which collapses the body of the stud to the screw (D) so that only the cloth plate will turn when opening or closing.

SETTING THE NEEDLES

With throat plate assembled in position, the needles should center in the throat plate needle slots (left to right). The needle head (A, Figs. 5 and 6) can be reposi-

Fig. 6

Needle Drive lever (C, Fig. 5 and 6) must also be positioned

Fig. 5 to set height of needles above throat plate which should be 7/16 inch (11.11 mm) on Styles 39800 CA and CB; 17/32 inch (13.49 mm) on Styles 39800 CP, CQ, CX, CY, VCP, VCQ, VCX, VCY with needles at top of stroke (W, Fig. 7). Tap the needle drive lever (C, Figs. 5 and 6) lightly up or down to obtain desired needle height. Needle gauge No. 21227 DD can be used by placing it on top of the throat plate and bringing the needle head bottom to rest on top of the gauge. This will have the needles at the bottom of their stroke. Note that the gauge has separate heights, one for high, the other for low capacity machines. Tighten screw (B. Fig. 6) securely.

SETTING OVEREDGE UPPER LOOPER OR SPREADER (Continued)

When looper or spreader is at the right end of its stroke, the holder should be set to position the looper or spreader shank approximately "X" degrees back of vertical and flush with the top of holder (Fig. 10) on all Styles except 39800 CA, CB; and approximately 1/16 inch (1.59 mm) above the holder on Styles 39800 CA, CB. On

later machines with the new looper/spreader holder (See Fig. 10 A), settings are the same for "X", "Y", and "Z" except for location of shank with respect to top of holder. This setting should be approximately 1/32 inch (.79 mm) above holder on all Styles except 39800 CA, CB, and approximately 3/32 inch (2.38 mm) above the top of holder on Styles 39800 CA, CB. These settings may vary depending on needle size. NOTE: Lines in bed casting represent 15, 30 and 45 degrees back of vertical. CAREFULLY set looper or spreader point to cross lower looper to the left of lower looper eye with approximately .002 inch (.051 mm) clearance. At extreme left end of travel the loop-er point or the lower point of the spreader should be set "Y" dimension to the left of the centerline of the right needle and "Z" dimension above throat plate (Fig. 11).

Now check relationship between looper or spreader and needle to ensure no deflection. If needle rubs back of either, pull looper or spreader out of its holder slightly and rotate the holder forward a short distance. These same adjustments, in opposite movement, will reduce the clearance between looper or spreader and needle. Reset to lower looper and recheck crossover setting. NOTE: on larger size needles (125/049 and 140/054), some needle deflection may result, but should not exceed. .002 inch (.051 mm). Fig. 12

SETTING 401 STITCH LOOPER

Insert 401 stitch looper into looper holder and press down until the butt end of the shank strikes the looper shaft. Looper will be at correct height. Tighten the looper clamp screw while working the looper blade to and fro to secure accurate seating of clamp screw against flat on shank.

With looper at the right end of its stroke, set looper 3/32 inch (2.38 mm) from centerline of left needle (Fig. 12), using looper gauge No. 21225-3/32. Loosen looper holder binder screw (A, Fig. 12) to position the looper.

Turn the handwheel to bring the looper point up to the needle and set the looper point to touch the needle without deflecting, approximately .001 inch (.025 mm) clearance, viewing the machine from the left end (Fig. 13). Retighten looper holder binder screw. Check for .025 inch (.635 mm) minimum 401 looper clearance under throat plate.

SETTING 401 STITCH LOOPER (Continued)

These machines are fitted with an adjustable 401 looper avoid link to accommodate extreme needle sizes from 075/029 to 140/054. Machines shipped from the factory will, have the setting for the sizes as listed under the "NEEDLES" paragraph, unless otherwise specified. Should adjustment become necessary, drain oil from the machine and remove bottom cover. Loosen nut (A, Fig. 14) and rotate eccentric stud (B) to align the letter "S", "M" or "L" which represent small, medium or large looper avoid, respectively, with timing mark in looper avoid link (C) as required. To

ensure a uniform setting, position the needle head at the bottom of its stroke before aligning the letter on the eccentric stud with respect to the timing mark in the looper avoid link. Recommended settings for machines using needles sizes:

075/029, 080/032, 090/036 ---- "S" 080/032, 090/036, 100/040 ---- "M" 110/044, 125/049, 140/054 ---- "L"

Tighten nut (A) to 24-25 in lbs. (28-29 cm/kg). Replace bottom cover and fill machine to proper oil level.

Fig. 14

While hand turning machine through cycle, observe the action of the needle with relation to the looper. As needle rises from the bottom of its stroke, the looper will approach the needle from the right side and pass behind same at top of needle scarf without striking. Further rising of the needle will result in the looper point entering the scarf. Furthermore, since the needle point is coming off the rear guard, the needle will resume its normal position by moving to the rear, resulting in a close relation of the needle and looper, or actual contact, until scarf passes looper. On the down stroke, the needle should pass behind the looper without the point glancing off the guarding surface of the looper.

SETTING 401 STITCH REAR NEEDLE GUARD

Insert rear needle guard into the hole in the throat plate support bracket. When 401 looper point is at the center of the needle scarf, set 401 rear needle guard (E, Fig. 9) so it touches but does not deflect needle, .000 to .004 inch (.000 to .102 mm) clearance. This guard setting will be approximately 3/16 to 7/32 inch (4.76 to 5.56 mm) below throat plate seat. With needle in down position, guard should not pinch thread in needle eye. Then lock the guard in place with set screw (F).

SETTING 401 STITCH FRONT NEEDLE GUARD

With needle at bottom position, set front 401 needle guard (G, Fig. 9) to touch but not deflect needle, .000 to .004 inch (.000 to .102 mm) clearance. Guard should not pinch thread in needle eye. Check for clearance between 401 looper and front 401 needle guard. Turn handwheel in operating direction, making complete revolutions to check whether needle is disturbed or pinched. Lock with screw (H).

For convenience, the looper may now be threaded as shown in (Fig. 2 or 2A) and as described under paragraph "To Thread 401 Looper". Replace differential feed dog, throat plate, lower knife holder and reset upper knife. Check cutting action with thread.

SETTING THE FEED DOGS

Assemble main and differential feed dogs (A, B, Fig. 15).

Feed dogs should be level with the throat plate surface by rotating feed tilting adjusting pin (C). This pin raises or lowers the back end of feed bar. Feed dogs should be level at the time teeth first appear above the throat plate. Screw (D) locks the feed tilting adjusting pin in place. Now set feed dogs at highest point of travel. Main and differential feed dog teeth should be set 3/64 inch (1.19 mm) above the throat plate.

SETTING THE LOWER KNIFE

Replace the lower knife holder assembly, In replacing the lower knife holder assembly, tighten screw (A, Fig. 16) so that when the face of the flange on sleeve (B) seats against throat plate mounting bracket (C), a free lateral motion of the lower knife and holder assembly is obtained when the knife is manually pressed at its upper corner. Lower knife (D) should be set with cutting edge flush with top of throat plate. Adjustments are made with hexagonal head screw (E) which holds the lower knife. Lower knife is spring pressed against the upper knife, so no lateral adjustment is necessary when the width of trim is changed.

Lower knife may be secured in any position by tightening screw (F) and locking nut (G) against support bracket. Because screw (F) also serves as latch pin for the cloth plate latch spring, it should always be locked with nut (G) even when screw is not tightened against lower knife holder.

SETTING THE UPPER KNIFE

Replace the upper knife assembly. Clamp upper knife (H, Fig. 16) in position, setting nut (J) to hold clamp (K) in its most clockwise position against upper knife. At the bottom of its stroke, front cutting edge of upper knife should extend not less than 1/64 inch (.40 mm) below cutting edge of lower knife. The chain guard (L) should be set down against the upper knife and slightly back from the cutting edge.

After upper knife has been set for proper width of trim, screw (E, Fig. 15) should be tightened to lock upper knife holding block (F) in place. This will simplify resetting when upper knife is replaced.

SETTING THE STITCH LENGTH

Length of stitch is determined by the combination of feed eccentrics used. Outer (left) eccentric (A, Fig. 17) actuates main (rear) feed dog, while the inner (right) eccentric (B) actuates the differential (front) feed dog. In assembling feed eccentrics, be sure hubs are facing each other. Be careful not to damage shaft or key.

Labeled mechanical assembly diagram showing components A through G with numbered parts

Fig. 17

To change feed eccentrics, remove screws (A, Fig. 18) securing cast-off support end plate (B); remove screws (C) and screw securing the extreme right end of cast-off support plate (D) accessible with chip chute (E) open; turning handwheel to position 401 looper at extreme right, permitting removal of the left main feed thrust bar guide (F) with cast-off support plate (D) assembled. Remove nut (C, Fig. 17) and looper thread take-up (D) from end of shaft (E). Turn handwheel in operating direction until key slot in eccentric is toward front. Using hooked eccentric extractor supplied with machine, reach behind eccentrics and withdraw eccentrics. It may be necessary to move handwheel back and forth slightly during extraction.

If eccentrics are unusually tight fitting, in addition to removing nut (C) and take-up (D, Fig. 17) from shaft (E), it may be helpful to remove nut (F) and feed driving connection (G). Then continue as originally suggested.

NOTE: Before tightening nut (C, Fig. 17) refer to paragraphs under "401 Looper Thread Control Adjustments".

SETTING THE PRESSER FOOT

Assemble the presser foot to presser arm. With needle in high position, swing presser arm into sewing position and set the presser foot to align needle holes (front and back) and flat on throat plate. The front edge of needle hole in presser foot must be aligned with front edge of needle hole in throat plate. It is also important that the bottom of the presser foot lies flat on the throat plate. If necessary, presser foot can be realigned with throat plate slots by shifting the foot lifter lever shaft (A, Fig. 19). To move the shaft, loosen screws in collar (B) and clamp screw (C) and then shift the foot lifter lever shaft to the left or right as required. Retighten collar screws and clamp screw.

Fig. 19

SETTING THE PRESSER FOOT (Continued)

The foot lifter lever arm (D, Fig. 19) and the collar (B) secure the shaft. Be sure the presser arm does not bind and rise when presser foot release lever is unlocked.

Adjust lifter lever stop screw (E, Fig. 19) so that presser foot can be raised no higher than upper looper or spreader will permit; then lock the nut (F). There should be from 1/16 to 1/8 inch (1.59 to 3.18 mm) free motion of foot lifter lever before the presser foot begins to rise. This adjustment should be made with screw (G) and locked with nut (H). Re-assemble the chip guard, fabric guard and cloth plate. To assemble chip guard, turn handwheel until upper knife assembly reaches its highest position.

NOTE: Tractor presser foot to be set with front wall of 401 needle slot in presser foot to be 1/16 inch (1.59 mm) forward from front wall of 401 needle slot in throat plate. Check to make sure 401 and overedge needle does not interfere with presser foot when presser foot is raised to highest position and front portion of foot is tilted down in front.

401 LOOPER THREAD CONTROL ADJUSTMENTS

Check alignment of looper thread take-up (A, Fig. 20) in slot of cast-off support plate (B), which should be centered horizontally and vertically. Should adjustment be necessary, loosen screws (C), reposition plate (B) as required while rotating handwheel several revolutions. Tighten screws (C) securely.

With the needle head at the top of its stroke, the long flat of looper thread take-up (A, Fig. 20) should be positioned to begin taking up slack of the looper thread (long flat parallel to cast-off support plate). It may become necessary to slightly advance or retard take-up later, to produce a satisfactory 401 stitch.

The adjustable eyelets (D, Fig. 20) partially determine the amount of looper thread that goes into the stitch. When set at their lowest position, the maximum amount of thread is drawn. Initial setting should be 1/8 inch (3.18 mm) from the highest position. They may be lowered to put more looper thread into the stitch as required.

A C D B E C

Fig. 20

Set pigtail eyelet (E, Fig. 20) initially at the six o'clock position. Vary this position slightly, if necessary, until the 401 looper thread is taut when the needles reach their highest position.

NOTE: When eccentric cams are changed or looper thread take-up requires adjustment, always torque nut (C, Fig. 17) to 24-25 in. lbs. (28-29 cm/kg).

NOTE: For lighter thread, cast off looper thread 1/32 inch (.79 mm) below throat plate.

STARTING TO OPERATE

Be sure the machine is threaded according to the threading diagram (Fig. 2 or 2A).

Set thread tube (W, Fig. 2 or 2A) so the opening at its left end aligns with thread tube (T), though later it may be repositioned slightly to suit conditions. With needles at high position, the opening of the lower looper thread take-up wires (U) should be centered between the thread tubes, front to back. Adjustment can be made by loosening screw (A, Fig. 21), resposition take-up wire lever as required and retighten screw. A preliminary setting of the lower looper cast-off blade. (V, Fig. 2 or 2A) is to position its curved section to contact thread as soon as the needle

head commences its downward stroke and barely touches the thread on its vertical surface located at the heel of the blade as the needle head completes its downward stroke. The cast-off blade can later be raised or lowered to increase or decrease amount of thread required in the system.

Fig. 21

NOTE: When adjusting cast-off blade and tightening its mounting screw, be sure that the fabric guard rests on top of thread tube (T).

OVEREDGE NEEDLE THREAD CONTROL

While sewing on material, check needle thread control as follows: Usually all needle thread is drawn on needle down stroke. Needle thread take-up (AM, Fig. 2 or 2A) should be set approximately in the center to upper portion of its slot, though it can be adjusted up or down to suit conditions. With the needle head at lowest position, the finger of the take-up (AM) should be set approximately 1/32 inch (.79 mm) below the thread holes in eyelet (AL) for the 504 stitch. The 503 stitch requires more strike-off and should be set approximately 1/8 to 3/16 inch (3.18 to 4.76 mm) depending on thread, material and stitch length. With needle head at highest position, the curved section of thread take-up (AM) should barely touch the needle thread. Adjust eyelet bracket (AL) forward or rearward to meet these conditions.

UPPER LOOPER THREAD CONTROL

With needles at high position, set looper thread eyelet (AH, Fig. 2A) approximately horizontal and so positioned, with thread taut through eyelet holes, thread barely contacts inside front wire of the left take-up wire (U). Make sure when needles are at down position, the rear wire of the left take-up wire (U) does not strike the inside of eyelet (AH). Usually all looper thread should be drawn on needle down stroke.

401 NEEDLE THREAD CONTROL

Set needle thread adjustable eyelet (AR, Fig. 2 or 2A) so that most of the needle thread is drawn on the down stroke. Eyelet (AS) located at top of needle head should be positioned with the bottom eye in line with the left needle.

THREAD TENSIONS

With take-ups and eyelets set, as described under thread controls, balance the thread tensions to obtain desired 401 and overedge stitch.

"AIR-KLIPP" VACUUM CHAIN CUTTER ADJUSTMENTS

The "AIR-KLIPP" chain cutter tube should be assembled as close to the cut-out in the throat plate as possible without touching; .005 inch (.127 mm) to .030 inch (.762 mm) clearance.

"AIR-KLIPP" VACUUM CHAIN CUTTER ADJUSTMENTS (Continued)

Check that knife pressure is only enough to ensure proper cutting. Set movable knife to trim.

The "AIR-KLIPP" chain cutter should be capable of cutting, NOT TEARING, a single strand of thread when turning machine over by hand.

The cutting edge of the movable knife should extend beyond the cutting edge of the stationary knife a minimum of 1/64 inch (.40 mm) when at extreme right end of stroke.

Care must be taken to provide clearance between movable knife and inner wall of "AIR-KLIPP" chain cutter tube when the movable knife is at the extreme right end of stroke.

Lubricate felt, oil wick and movable knife with a straight mineral oil equivalent to Union Special Specification No. 175.
