Loosen nut (C, Fig. 22) and turn screw (D) down approximately 1/8 inch (3.2mm) below bottom surface of presser bar guide (B). Loosen screws (E) in presser bar guide (B). Adjust spring regulator nut (C, Fig. 23) as required, so its lower surface is 5/8 inch (15.9mm) from top of yoke (B) as viewed in Figure 23. With presser foot resting on throat plate and feed dog down below throat plate, press down on spring regulator nut (C) until the marks in presser foot bottom align with centerline of needle and positioned to keep needle in center of needle slot. Tighten screws (E, Fig. 22) securing presser bar guide to presser bar, ensuring stop screw (D) in presser bar guide is resting on bottom of presser bar guide plate.

Replace presser bar spring, spring guide and spring regulating screw. Turn regulating screw down until the top of its threaded portion is level with head casting. Rotate handwheel to position feed below throat plate with presser foot resting on throat plate. Depress presser foot lifter lever to see if presser foot bottom moves SLIGHTLY towards the rear before presser foot begins to lift. Adjustment can be made by turning stop screw (D, Fig. 23) clockwise to shorten or counterclockwise to lengthen the distance of travel.

Loosen screw (F, Fig. 22) in lifter arm (G) and rotate arm slightly as required to obtain 1/16 inch (1.6mm) clearance between link (A) and guide (B); retighten screw (F) ensuring no left to right shake in lifter arm (G).

Presser foot, at back of needle slot should cover most of throat plate land when resting directly on throat plate.

When presser foot bottom is raised by material and the feeding foot spring bottoms, rear of needle slot should clear the needle. Main presser bar should not begin to lift before the spring of feeding foot bottoms.

Purpose of the feeding presser foot is to make top and bottom plies of material feed the same amount without pulling on the bottom ply. Final adjustment may be required to match plies; turning nut (C, Fig. 23) to increase pressure on spring (A) will tend to feed the bottom ply more... decreasing pressure will tend to feed the top ply more.

H C A F D B 1/16 inch (1.6mm) E G A230

Fig. 24

With needle bar at bottom of stroke and presser foot resting squarely on throat plate, there should be a minimum clearance of 1/64 inch (.4mm) between the bottom of screw (A, Fig. 24) and bottom of slot in presser bar guide plate (B). At this time, there should be at LEAST 1/32 inch (.8mm) clearance between bottom of presser bar guide and top of lower presser bar bushing.

There should also be 1/16 inch (1.6mm) clearance between bottom of slot in lifter lever link (C) and bottom of presser bar guide (D) when foot lifter lever is released. If adjustment is required, proceed as follows:

Back off presser bar spring regulator to release tension on spring. Loosen two screws (E) in presser bar guide (D). Loosen nut (F) and turn screw (A) down against guide plate (B) to obtain at least 5/64 inch (2.0mm) clearance between bottom of presser bar guide (D) and guide plate (B). Align presser foot with needles and press down FIRMLY while tightening two screws (E) in presser bar guide (D).

NOTE: This setting was necessary to prevent damage to the scraper edge of presser bar bushing, should presser foot be removed from machine.

Fig. 25

Turn presser bar spring regulator down. Back off screw (A) to obtain the 1/64 inch (.4mm) dimension between bottom of screw and bottom of slot in presser bar guide plate (B), lock nut (F).

Loosen screw (G) in lifter arm (H) and rotate arm slightly as required to obtain the 1/16 inch (1.6mm) dimension between link (C) and guide (D), retighten screw (G) ensuring no left to right shake in lifter arm (H).

Adjust presser bar spring regulator so it exerts only enough pressure on presser foot to feed the work uniformly. Turning it clockwise increases the pressure, counterclockwise acts the reverse.

THREAD TENSION RELEASE

Needle thread tension assembly (A, Fig. 25) is set correctly when the tension discs (B) begin to release thread as the presser foot is raised to within 1/8 inch (3.2mm) from the end of its travel and completely released when presser foot has

reached its highest position. Adjustment can be made by loosening screw (C) and lower the tension assembly (A) to advance the release action or raise tension assembly to retard the release action. Hold tension assembly in desired position while retightening screw (C).

Loosen lock nut (A, Fig. 26) and adjust screw (B) in presser foot lifter lever, allowing presser foot to be raised to its highest position without interfering with needle head. Lock nut (A) securely.

LOOPER THREAD TAKE-UP AND CAST-OFF PLATE

Looper thread take-up (A, Fig. 27) should be centered, left to right, in cast-off plate (B). As the needle bar is descending, the take-up should be in position to cast-off looper thread just as the tip of needle is even with the bottom of looper. Adjustment can be made by loosening two screws in take-up (through access hole in cast-off plate), reposition take-up as required and retighten screws. Set adjustable eyelets (C) 1/2 inch (12.7mm) below centerline of their mounting screws.

If cast-off wire is rubbing take-up, loosen screw (D), center the wire (E) and retighten screw. If retaining finger is rubbing take-up, loosen screw (F), center the finger (G) and retighten screw. If retaining finger is on an angle, loosen screw (H), turn retaining finger support (J) slightly as required and retighten screw. Height of cast-off plate is set correctly when the lowest point of take-up cam is even with the top surface of cast-off plate. Adjustment can be made by turning handwheel in operating direction to locate the lowest point of the take-up cam, loosen screw (K) and raise or lower cast-off plate to correct height; then tighten screw (K) securely.

THREAD CONTROL SETTINGS

(For Styles XF511B100MF, XF511E101MF, 118MF, 152MF, XF511H100MF, MG, MAW, 112MF, 112MG and 151MF)

Needle bar eyelet (A, Fig. 28) and needle thread cam (B) should be set in conjunction with each other so needle thread just contacts needle thread cam (B) at TOP and BOTTOM of stroke.

Adjustments can be made by bringing needle bar up, loosen screw (C) slightly, reposition eyelet (A) up or down as required. TORQUE screw (C) to 10 in-lbs. (11.5 cm/kg). Needle thread cam can be adjusted forward or rearward as required by loosening needle thread cam mounting screw (D) and retighten screw. Loosen screw (A, Fig. 29) and position strike-off wire (B) 1/2 inch (0.5mm) from top surface of top cover to underside of strike-off wire. With needle bar at BOTTOM of stroke and Thread Control Assembly adjustable eyelet (C) set at "T". Apply necessary tension to both needle and looper-thread and start to sew. Looper thread tension should be light. Adjust needle thread tension to pull up smallest needle loop as required. At this point a tight stitch will be achieved. Without changing needle thread tension move Thread Control Assembly adjustable eyelet to "L". This will produce a loose seam with longer needle loops.

NOTE: Adjustment of strike-off wire can be raised to accommodate thick dense material.

Needle thread take-up cam wire (C) should be set to barely contact needle threads with needle bar at top of stroke. Adjustment can be made by loosening cam mounting screw (E), reposition cam forward or rearward as required and retighten screw. Auxiliary strike-off (F) should be set so needle threads contact strike-off when needle bar is at BOTTOM of stroke with Thread Control Assembly adjustable eyelet (C, Fig. 29) set at "T". Loosen screw (A) and position strike-off (B) as specified and retighten screw. Thread tension on needle thread should be just enough to pull up uniform stitches. Thread tension applied on looper thread should be just enough to steady thread.

POWER "AIR-KLIPP" CHAIN CUTTER ADJUSTMENTS

NOTE: References to Fig. 31 are as viewed from rear of machine; references to Fig. 32 are as viewed from left end of machine.

Upper knife (A, Fig. 31) can be replaced by removing two screws (B). In order to replace lower knife... the upper knife, rear cover and thread inlet must be removed. Lower knife (C) is held in position by roll pin (A, Fig. 32) and tension spring (D, Fig. 31). To remove lower knife, lift up and tilt to the right. When replacing lower knife, be sure to engage end of tension spring through the hole in the side of lower knife before inserting in the slide block (E). Also be sure that the slot in lower knife is located over roll pin.

SETTING KNIFE CROSS OVER

Adjustment will be necessary after replacing or repairing knives. With sewing motor switch in "OFF" position and air line connected to air motor, depress treadle until air motor begins to operate.

IMPORTANT! Be sure that lower knife does NOT strike against knife housing or feed chamber cover. Adjustment should be accomplished by loosening one screw (F, Fig. 31) and reposition left or right slightly.

Carefully press against slide block (E, Fig. 31) until air motor stalls.

With treadle still depressed, check the knife cross over. The cross over of the lower knife to the upper knife is positioned correctly, when the lower knife is 1/32 inch (.8mm) from the front of the upper knife as shown in Figure 31. If adjustment is required, loosen screw (F), reposition slide block (E) slightly as required. Retighten screw (F) and recheck cross over.

SHEAR ANGLE ADJUSTMENT

Shear angle should be .003 inch (.076mm), measured at rear cutting edge of lower knife (B, Fig. 32) and cutting edge of upper knife (D).

Adjustment can be made by turning lower knife adjusting screw (C, Fig. 32) counterclockwise (a small amount at a time) while manually

operating slide block (E, Fig. 31) continuously checking with a piece of thread to see if knives are cutting. As soon as the knives fail to cut the thread and the shear angle is zero, turn screw (C, Fig. 32), same as (G, Fig. 31) clockwise approximately 1/4 turn. Check cutting action of knives with sewing motor switch "ON".

SETTING PRESSURE VALVES

Regulate valve on pneumatic control devices for air motor of the "AIR-KLIPP" Chain Cutter to approximately 20-22 p.s.i. (1.5 bar) when air motor is operating. Regulate valve on pneumatic control device for the suction air to obtain maximum suction, yet so that the FABRIC TO BE SEWN will not be cut by the "AIR-KLIPP" Chain Cutter knives.

PULLER TIMING

A B A D C A237

Fig. 34

The Close-Coupled Puller (BELT or ROLLER) must be timed so the intermittent feeding action stops before the needle/s is/are entering the work. NOTE: This will depend on the thickness of material and stitch length being sewn. If adjustment is required, remove top cover which is secured with four screws. Loosen four set screws (A, Fig. 33) in sprocket (B). Advance or retard sprocket on shaft as required. When proper timing is obtained, position sprocket on its shaft (left or right) so drive belt is centered in the puller drive assembly. Torque four screws (A) to 35 in-lbs (40 cm/kg).

There should be approximately 1/8 inch (3.2mm) deflection in puller drive belt (A, Fig. 34) when pressing firmly between sprocket (B) and puller drive assembly. Adjustment can be made by loosening one screw (C) securing eccentric (D) and rotate eccentric counterclockwise as viewed in Figure 34, to tighten belt, clockwise acts the reverse. Be sure to maintain .006-.010 inch (.150-.254mm) between eccentric and drive housing. Tighten screw (C) securely. Replace top cover and tighten four screws.

The feeding motion of the puller is achieved by two sprockets. By using various combinations of nine different sprockets, (59) different puller stitch lengths can be obtained. Refer to sprocket charts on Page 28 that list the various sprocket combinations. NOTE: Actual stitch length may vary slightly due to material being sewn. When ordering sprockets use the appropriate dash number. Example: C50042-Z-( ).

To change sprockets loosen two screws (A, Fig. 35) and position screws to top of bracket to release tension on stitch length drive belt. NOTE: Belt guard has been removed for clarity. With drive belt in relaxed position, sprocket (B and C) can be removed. When installing sprockets (B and C) make sure that hub of sprocket is flush with end of shaft and 1st screw in operating direction is on the flat of shaft. Reassemble drive belt, tighten 2nd screw in sprockets (B and C) securely. Rotate handwheel in operating direction to make sure belt does not bind within belt guard. It may be necessary to reposition sprockets (B and C) slightly (left or right). Pull down firmly on puller assembly, making sure puller roller is setting evenly on Idler Roller and tighten two screws (A) securely.

The roller puller belt, which is located under hinged belt guard (D) should have 1/8 inch (3.2mm) deflection when pressing firmly between drive sprockets. If adjustment is required loosen two allen screws (A, Fig. 36) and turn eccentric shaft (B) slightly to apply tension on belt. Turning shaft clockwise tightens belt counterclockwise acts the reverse. CAUTION! Care must be taken not to disturb eccentric shaft (left or right). Tighten two screws (A) securely.

Belt Puller (A, Fig. 37) must be setting evenly on cloth plate (B). On Style XF511E152MF Belt Puller will rest on "AIR-KLIPP" inlet.

PULLER STITCH LENGTH (Continued)

Belt puller drive belt (A, Fig. 38) should have approximately 1/8 inch (3.2mm) deflection when pressing firmly between drive sprockets. If adjustment is required hold lock nut (B) and loosen lock nut (C). Turn nut (B) to apply tension. Hold nut (B) firmly and tighten nut (C) securely.

IDLER ROLLER

Puller Roller must be set evenly on Idler Roller (A, Fig. 39) to ensure that the material will be pulled straight through the sewing area. Adjustment for feeding can be made by shimming Idler Roller if necessary to achieve even mating. To shim roller remove one screw (B, Fig. 39) securing roller assembly. Remove Idler Roller Assembly and add shims as necessary between plate and bearing blocks to ensure even mating between Puller Roller and Idler Roller.

PULLER LIFT ADJUSTMENT

With puller in operating position and presser foot resting on throat plate there should be 1/32 inch (.8mm) between puller lifter link (A, Fig. 40) and puller lifting pin (B). If adjustment is required loosen screw (C) in upper presser foot lifting shaft connection and raise or lower link (A) as required. Tighten connection screw (C) securely.

NOTE: When presser foot starts to lift, puller must lift at the same time.

For sewing operations not requiring puller action the machine can be run with puller raised off the material by turning the manual lock-up pin (D) up to position under stop collar (E). If the puller has insufficient clearance to clear material, stop collar (E) can be raised or lowered on tension shaft (F)

PULLER LIFT ADJUSTMENT (Continued)

to suit. Adjust puller tension regulator (G) so it exerts only enough pressure on puller to feed work. Turning regulator clockwise to increase the presser, counterclockwise acts the reverse. If material does not pull straight through behind presser foot adjust main stitch length slightly so material will lay flat, until material is straight.

STITCH SHORTENING DEVICE

Stitch shortening device is set at the factory to produce one-half of the recommended stitch length per inch. If adjustment is required loosen lock screw (A, Fig. 41) and turn stop screw (B) clockwise for less stitches per inch, counterclockwise gives more stitches per inch.

The connecting arm (A, Fig. 42) is connected to the collar adaptor (B) located on the feed rocker shaft (C). The connecting arm (A) activates the feed rocker shaft to achieve the desired stitch length depending on operation.
