Looper Gauges

8-gauge machines	=	Gauge No. 21225 - 7/32" (5,56 mm)
12-gauge machines	=	Gauge No. 21225 - 3/16" (4,76 mm)
16-gauge machines	=	Gauge No. 21225 - 5/32" (3,97 mm)

Needle Lever Stud

Check the location of the needle lever stud with respect to its oil groove. The head of the needle lever stud is marked with an arrow and the word "up". The stud is set correctly when the arrow points vertically up. Also, check the position of the oil tube inside the arm casting which lubricates the needle lever stud. Make sure it is tilted downwards and its delivery end contacts the wall of the bed casting just above the notch in the needle lever thrust collar. Do not allow the oil tube to rest on the needle lever.

Lubrication

Fill the oil reservoir (drawing No. 20549 Q) as the oil has been drained before shipment. Use "Mobil DTE Oil 'Medium'" (straight mineral oil, Saybolt viscosity of 200 to 250 seconds at 100^ ) or another oil with same specifications.

When filling the oil reservoir and before starting operation be sure that the oil level is between the two red lines of the oil gauge (CAUTION! The oil level should never be above the upper red line). Lubrication is automatic, including the cylinder arm. For draining the oil there is a plug screw in the base plate located below the looper thread take-up (drawing No. 20549 Q). Normally, the oil should be drained completely and renewed once a year. Also, take off the cylinder arm cover and remove the lint which may have found its way into the cylinder. Seal the cylinder arm cover and tighten the three cover screws.

Setting the Needles

Put in two new needles Type 121 GBS (128 GAS needles can also be used). The 8- and 12-gauge machines have a retainer needle Type 31111-027. Insert the needles into the needle head as far as they will go with long grooves of the 121 GBS needles toward the operator. The retainer can be set without any attention because there is no eye or groove. The needles should be in the center of the needle holes in the throat plate.

Looper Adjustment

Insert the looper into the looper holder and tighten screw against the flat on shank. With the needle bar at the bottom of its travel the looper gauge (distance from the center of the left needle to the looper point) must be adjusted according to the following table:

8 gauge machines

12 gauge machines

16 gauge machines

Looper Gauge

7/32" = 5,56 mm	21225 - 7/32"
3/16" = 4,76 mm	21225 - 3/16"
5/32" = 3,97 mm	21225 - 5/32"

To adjust the looper gauge loosen the hexagonal screw No. 22792 C by using socket wrench No. G 21388 AE and turn the looper holder until the looper point has the correct gauge to the left needle. Tighten the hexagonal screw.

Setting Looper to Needle and Looper Avoid Motion

When the looper moves to the right the looper point should pass the rear of the left needle as closely as possible without contacting (.002 inch clearance). This adjustment is made by

less more 21389

loosening the hexagonal screw No. 22792 C, using socket wrench No. G 21388 AE and moving the looper holder axially. Tighten hexagonal screw and check the looper gauge. If it is necessary to have more or less looper avoid motion, remove cover plate No. 31182 N at the rear of the machine (CAUTION! Handle cork gasket with care). Now, the looper avoid segment is accessible for avoid motion adjustment. Loosen the nut with wrench No. 21388 AE (see sketch). To increase the avoid motion the connection link must be moved downwards and to reduce upwards. Tighten the nut and replace the cover plate. No. 31182 N with the cork gasket.

Looper Needle Guard

The looper needle guard is set correctly when it moves to the right and barely touches the left needle and a space of about .002 inch (0,04 - 0,05 mm) remains between looper point and the rear of the left needle.

Height of the Needle Bar

Set the needle bar so that the top of the right needle eye is 3/64" (1,2 mm) below the looper point when the looper is moving to the right and its point is even with the right side of the right needle. To adjust the needle bar height loosen needle bar clamp screw No. 22562 A.

Needle Bar Travel Adjustment

The needle bar travel of the machine is adjusted at the factory for 1 7/32" (31 mm). Should it be necessary to increase the needle bar travel for heavy weight fabrics or to reduce it for

6 21227 E 3.25 3.25 BP 106

light weight material, it can be adjusted from 1 9/32" (32,5 mm) to 1 5/32" (29,5 mm). To change the needle bar travel remove cover No. 52882 AD and loosen clamp screw No. BP 108 on the needle lever by using wrench No. 21388. To increase the needle bar travel, the ball stud should be moved toward the needle bar. Moving it in the other direction decreases the needle bar travel. Gauge No. G 21227 E can be used advantageously for setting the needle bar travel correctly (see sketch). Tighten the clamp screw.

Adjusting the Stitch Length of the Non-Differential Feed Machine

The mechanism for setting the stitch length is located in the cylinder (see sketch). This mechanism is accessible after removing plug screw No. 22539 D which is located above and to the rear of the handwheel. Loosen the ball screw No. 31133 B by turning left

longer shorter 31133 B 22539 D

and move it in the feeding segment. Moving downwards results in a shorter stitch length and upwards in a longer one. When setting the longest stitch length (approximately 6 S.P.I.) be sure that the feed dog has a minimum clearance of about .020" (0,5 mm) at the front and rear of the throat plate slots. Tighten ball screw and replace plug screw No. 22539 D.

Setting the Differential Feeding

On the handwheel side there is a lever with a knurled screw which rests on a graduated curved plate for changing the differential feeding. The graduated plate has no definite measurements, the marks are only for comparison.

Turning the knurled screw to the left increases the amount of differential action and turning this screw to the right decreases the differential feeding. The ratio can be changed from non-differential to 2:1 differential action.

CAUTION! Both feed dogs are set at the factory so that they do not contact each other. If it is necessary for a special fabric to make the distance between the feed dogs smaller, use the following directions:

Loosen the three screws of cylinder arm cover. Then take off cylinder arm cover carefully (do not damage cork gasket) by using a screw driver at the side of the looper thread groove.

clearance x clamp screws No. 31135 B main Feed bar clamp screws No. 97 diff. Feed bar

Now the feed bars are accessible and adjustable by loosening clamp screws No. 31135 B and No. 97 (see sketch). After finishing adjustment tighten clamp screws and replace cylinder arm cover with gasket and rubber sealing cord. Damaged gaskets or rubber sealing cords should be replaced by new ones.

Height of Feed Dogs

The feed dogs are set correctly when the tips of the teeth project 3/64" above the throat plate when the feed dogs are in the highest position. The height adjustment is made on the non-differential machine 31100 E by loosening set screws No. 22560 B and turning the eccentric stud No. 31139 A. After this adjustment tighten set screws.

In differential feed machines 31100 K and L the eccentric stud No. 31139 A must be in the lowest position. Each feed dog may be set independently of each other in the feed bar.

Presser Foot

The presser foot must set flat on the throat plate and in line with the needles. Be sure the hinge point and the yielding sections move freely.

With the presser foot raised the stop collar on the presser bar is set correctly when the needle shank or the needle bar head does not contact the presser foot when the needle bar is at the bottom of its stroke.

Pressure on the Presser Foot

The pressure regulating screw is the knurled screw located on top of the machine arm next to the needle bar. Set the pressure of the presser foot spring so that there is just enough pressure for proper feeding of the fabric.

Threading of the Machine

Thread the machine according to diagram No. 20549 Q and start sewing.

Looper Thread Take-Up

Technical line drawing of a mechanical device with no visible text or symbols

The double disc take-up must be set into the middle of cast-off plate slot. It is located at the left side of the crank shaft and is adjustable with two set screws (see sketch). When the needles move downwards and the looper begins to travel from extreme right to left, the take-up must contact the looper thread so that all slack is removed. The looper thread should cast off the high point of the take-up when the looper with its eye is at the right threaded needle.

Thread Guides on the Cast-Off Plate

Less looper more thread

At the right and left side of the double disc take-up on the cast-off plate there are adjustable thread eyelets. These eyelets must be set as close as possible to the double disc take-up. To adjust these eyelets towards the operator results in more looper thread in the system and moving them in the opposite direction, less looper thread will be drawn.

Looper Thread Control

The looper thread retainer No. 31104 which is mounted on the cast-off plate support can be moved up and down, and from side to side. It should be set laterally so that it is midway between the two discs of the take-up. The height of the retainer affects the control of the looper thread as the looper moves to the right. More looper thread is given to the stitch when the retainer is raised. However, if the retainer is raised too high, the looper thread may be wiped under the looper causing triangle skips or pulled down stitches. This can be checked by observing the action of the looper thread as the looper moves to the right.

Thread Tension

The tension on the needle threads should only be sufficient to produce uniform stitches on the bottom side of the fabric. The looper thread tension should be approximately one fourth of the tension which is applied to each needle thread.

Needle Thread Guide and Take-Up Wire

The needle thread guide No. G 52758 is set in a straight line with the thread of the lower tension (see drawing No. 20549 Q). If it is necessary to have more needle thread turn the guide upwards. Set the take-up wire so that the thread of the left needle just contacts the wire when the loop of the left needle is released from the looper.

Seam Test

Unravel the stitch and check thread to see if it is chafed from sharp feed dog teeth, if so, the feed dog teeth may be stoned slightly to remove the sharp edges.

Needle Thread Nipper

The needle thread nipper is not assembled at the factory. It should be used for heavy threads or for threads which form a small needle loop.
