SAFETY RULES

CAUTION!

THIS 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

IMPORTANT: Machine must be in a leveled position.

Oil has been drained from main reservoir before shipment. Use a straight mineral oil with a Saybolt viscosity of 90 to 125 seconds at 100 degrees Fahrenheit. This is equivalent to UNION SPECIAL Specification No. 175. Remove oil filler cap (A, Fig. 1) and fill to the TOP line of oil level gauge (B). Replace oil filler cap.

CAUTION! On new machines, machines that have been out of service for an extended period of time OR machines that have been drained of oil and refilled.....RUN MACHINE SLOWLY at 300 R.P.M. for approximately five minutes while paying strict attention to the oil flow indicator which should rise in the oil filler cap (A) and remain steady while machine is running. This must be noted to ensure that oil flow indicator is functioning and oil is circulating. Check oil level while machine is running which MUST be maintained between the red lines of oil level gauge.

To maintain maximum recommended speed and serviceability of these machines, refer to General Preventive Maintenance Schedule. Under no circumstances, should oil remain in the machine for more than one year. Oil drain plug is located in bottom of oil pan. ALWAYS change oil filter when oil is changed. At this time, evaluate the contaminated condition of the oil to determine if the oil filter should be changed more or less frequently. To replace filter, remove four screws (C, Fig. 1) and cover (D); lift out filter cartridge. REMOVE (brass) BY-PASS VALVE FROM TOP OF OLD FILTER AND INSTALL IN NEW FILTER. Reassemble in reverse manner.

TIMING FEED TO NEEDLE

Adjustment would be required if the machine is feeding while the needle is in the work.

This can be accomplished by removing top cover, head cover, left cloth plate and top feed chamber cover. Rotate handwheel in operating direction to position needle bar at bottom of stroke. At this time, the first screw (A, Fig. 2) in the feed drive eccentric (B) must be on the flat of the feed drive shaft and in a vertical position. Adjustment can be made by loosening two screws (A, Fig. 3) in upper mainshaft sprocket (B). Hold the handwheel firmly with needle bar at bottom of stroke and rotate pulley as required to position screw (A, Fig. 2) so it is vertical. Tighten screws (A, Fig. 3) securely.

SYNCHRONIZING LOOPER AND NEEDLE MOTIONS

NOTE: End cover has been removed for clarity in Figure 4, but MUST BE IN POSITION WHILE MAKING THE FOLLOWING ADJUSTMENTS.

Looper drive belt, (A, Fig. 4) has proper tension if, when turning handwheel in operating direction to position looper in the center of its (right to left) travel...there is no noticeable (right to left) play in the looper mechanism. There should be approximately 1/8 inch (3.2mm) deflection in looper drive belt when pressing firmly with thumb, midway between sprockets (B and C). Adjustment can be made by loosening two screws (A, Fig. 5) and turn looper module (D, Fig. 4) counterclockwise to tighten belt or clockwise to loosen, as viewed in Figure 4. Retighten screws (A, Fig. 5).

To synchronize machine, remove needle bar eyelet guard, needle thread take-up cam, needle, presser foot, throat plate, looper and feed dog. Turn handwheel to position needle bar at BOTTOM of stroke and looper holder at EXTREME right end of travel.

SYCHRONIZING LOOPER AND NEEDLE MOTIONS (Continued)

Using gauge No. 21227 R, mount gauge plate with throat plate attaching screws. Insert pin (included with gauge) into looper holder. Mount indicator block to machine head with one of the screws removed from needle bar eyelet guard. Insert shank of indicator gauge into indicator block and tighten screw against shank. (See sketch A for reference).

Rotate handwheel in OPERATING direction until the pin in looper holder contacts gauge plate. Loosen screw (A, Fig. 6) in needle bar connection (B) and position needle bar (C) as required to set the pointer of indicator gauge at "0" and tighten screw (A) VERY LIGHTLY.

NOTE: This screw is specifically tightened to ONLY 10 in-lbs (11.5 cm/kg).

Rotate handwheel in REVERSE direction until pin in looper holder again makes contact with gauge plate and note the reading on the gauge. A variation of (1) graduation on the scale is permissible. If the reading is above "0", loosen screws (E, Fig. 4) and turn rear looper drive sprocket (B) towards the operator (clockwise as viewed in Figure 4). If the reading is below "0", turn sprocket away from operator (counterclockwise as viewed in Figure 4). Temporarily snug screws.

Rotate handwheel in OPERATING direction until pin in looper holder contacts gauge plate and note the reading on scale. If the reading is above "0", loosen screws (E) and turn sprocket (B) away from operator (counterclockwise as viewed in Figure 4). If the reading is below "0", turn sprocket towards the operator (clockwise as viewed in Figure 4). Temporarily snug screws.

Continue to check and adjust in both OPERATING and REVERSE directions until pointer of indicator gauge comes within (1) graduation on the scale when turning the handwheel in either direction. Before tightening screws (E) securely, be sure to have .002 inch (.051mm) clearance between sprocket (B) and needle guard drive connecting rod (F).

LOOPER SETTINGS

Insert a new needle, type and size specified. With looper positioned at EXTREME right end of travel, distance from centerline of needle to point of looper should be 5/32 inch (4.0mm). Adjustment can be made by loosening screw (A, Fig. 7) and turn screw (B) clockwise to increase looper gauge or counterclockwise to decrease. Apply pressure to the upper portion of looper holder (C) to the left while making this adjustment and locking with screw (A). Looper gauge No. 21225-5/32 can be used advantageously while making this adjustment. Looper must also be set so, as it travels to the left behind the needle, NOT to touch, but with a MAXIMUM clearance of .005 inch (.127mm). Adjustment can be made by loosening screw (A) and moving looper holder (C) forward or rearward on its shaft to obtain specified conditions; apply pressure to the upper portion of looper holder to the left while tightening screw (A).

NEEDLE BAR HEIGHT

Turn handwheel in operating direction until POINT of looper (A, Fig. 8) is even with the LEFT side of the needle (B). TOP of needle eye should be 1/64 inch (.4mm) below the undersurface of looper blade, as shown in Figure 8. Adjustment can be made by loosening screw (A, Fig. 9) and move needle bar (B) up or down as required; TORQUE screw (A) to 10 in-lbs (11.5 cm/kg).

REAR NEEDLE GUARD TIMING AND ADJUSTMENT

Rotate handwheel in operating direction to position looper point at the RIGHT hand side of needle. At this time the needle guard (A, Fig. 10) should be at its EXTREME END of FORWARD travel. Adjustment can be made by loosening two screws (A, Fig. 11) and turn needle guard eccentric (B) slightly as required until this condition exists. Ensure .002 inch (.051mm) clearance between needle guard eccentric (B) and looper drive sprocket (C) while tightening screws (A) securely. Needle guard should also be positioned (left to right) so the needle centers in the width of the guarding surface. Adjustment can be made by loosening collar screw (D) and pivot link screw (E) permitting guarding surface to be centered to needle. Position collar against needle guard shaft bushing and tighten screw (D) securely. Rotate guard as required to obtain .002-.004 inch (.051-.102mm) clearance between guarding surface and needle. Take up thrust by exerting pressure against collar to the left and pivot link to the right and tighten pivot link screw (E) securely. Guard should be set as low as possible yet have its vertical face approach approximately 3/64 inch (1.2mm) of needle point. Adjustment can be made by loosening two screws (B, Fig. 10) to position guard to proper height and retighten screws (B) securely being sure to keep the width of its guarding surface centered to needle.

FEED DOG SETTINGS

Feed dog should be centered in throat plate with equal clearance on both sides and ends. At highest point of travel, feed dog teeth should extend the depth of a full tooth, or approximately 3/64 inch (1.2mm) above throat plate. MINOR (right to left) adjustments can be made by loosening two screws (A, Fig. 12) in throat plate support (B). Loosen two screws (C) securing two locating ferrules which allow

movement to align throat plate support. Reposition slightly as required, considering both needle hole slot and feed dog slots. Tighten screws (C) first, then screws (A).

Front to rear adjustment can be made by turning stitch regulating knob (A, Fig. 13) counterclockwise to obtain LONGEST stitch length. Remove rear feed chamber cover which is secured with four screws.

Loosen Allen screw (A, Fig. 14) and turn eccentric (B) while rotating handwheel in operating direction to obtain equal clearance in throat plate, front and rear. Tighten screw (A) securely.

Feed dog can be leveled or tilted by loosening screw (A, Fig. 15) and rotate feed rocker tilting shaft (A, Fig. 16) slightly as required. Check parallelism of feed dog by placing throat plate in position. Before tightening screw (A, Fig. 15), make sure to have approximately .002 inch (.051mm) clearance between feed rocker (B) and spacer sleeve (C).

IMPORTANT: Recheck front to rear clearance of feed dog in throat plate slots whenever feed rocker tilting shaft has been repositioned. Replace rear feed chamber cover.

With feed travel set to desired stitch length, set feed dog height as specified by loosening mounting screw (A, Fig. 17) to position as required. Feed dog supporting screw is located in the feed dog holder, adjust as required to support feed dog before tightening screw (A).

Recheck front to rear clearance under "FEED DOG SETTINGS" whenever stitch length is changed. Stop collar at rear of machine attached to stitch regulating knob shaft can be set to prevent stitch length regulating knob (A) from accidentally being turned beyond the desired stitch length.

PRESSER BAR AND PRESSER FOOT (For Styles LF611K100HM, 100MG, 100MW and 112MG)

With needle bar at bottom of stroke and presser foot resting squarely on throat plate, there should be minimum clearance of 1/64 inch (0.4mm) between the bottom of screw (A, Fig. 19) and bottom of slot in presser bar guide plate (B). 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 needle 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. Turn presser bar spring regulator down. Back off screw (A) to obtain the 1/64 inch (0.4mm) 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.

PRESSER BAR AND PRESSER FOOT (For Styles LF611K100MFand LF611K112MF)

With needle bar at bottom of stroke and presser foot resting on throat plate, there should be 1/32 inch (.8mm) clearance between top of screw and top of slot in presser foot as shown in Figure 19. There should 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: Loosen nut (F) and turn screw (A) down approximately 1/8 inch (3.2mm) below bottom surface of presser bar guide (D). Back off presser spring regulating screw and loosen screws (E) in presser bar guide (D) so that presser foot is sitting squarely on throat plate and screw (A) is touching the bottom of the presser bar guide plate, then secure screws (E).

Turn presser spring regulating screw all the way down, then back off screw (A) counterclockwise to obtain the 1/32 inch (.8mm) dimension in presser foot, 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). Make sure that there is no shake, left to right, in lifter arm (H).

FEEDING PRESSER FOOT (For Styles LF611K100MR and LF611K100MAW)

With presser foot resting on throat plate and the needle in its lowest position, the distance from top of spring (A, Fig. 20) to top of yoke (B) should be 5/8 inch (15.9mm) and the line stamped across the presser foot bottom should line up with centerline of needle.

As the presser foot is raised, its bottom should move VERY SLIGHTLY towards the rear...1/64 inch (.4mm) maximum. If adjustment is required, proceed as follows: Remove presser spring regulating screw, presser bar spring guide and presser bar spring. Loosen nut (F, Fig. 19) and turn screw (A) down approximately 1/8 inch (3.2mm) below bottom surface of presser bar guide (D). Loosen screws (E) in presser bar guide (D). Adjust spring regulator nut (C, Fig. 20) as required so its lower surface is 5/8 inch (15.9mm) from top of yoke (B) as viewed in Fig. 20. 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. 19) securing presser bar guide to presser bar, ensuring stop screw (A) in presser bar guide is resting on bottom of presser bar guide plate. Replace presser bar spring, presser bar spring guide and presser 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.

FEEDING PRESSER FOOT (Continued) (For Styles LF611K100MR and LF611K100MAW)

Adjustment can be made by turning stop screw (D, Fig. 20) clockwise to shorten or counterclockwise to lengthen the distance of travel.

Loosen screw (G, Fig. 19) in lifter arm (H) and rotate arm slightly as required to obtain 1/16 inch (1.6mm) clearance between link (C) and guide (D); retighten screw (G), assuring all end play is removed from lifter arm (H).

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

When the 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. 20) to increase pressure on spring (A) will tend to feed the bottom ply more...decreasing pressure will tend to feed the top ply more.

1 7/8 inch (47.6mm) 1 5/16 inch (33.3mm) STANDARD EYELET POSITION A126 EYELET POSITION FOR LOOSE STITCH Union Special.

As a starting point, the needle thread (adjustable) eyelet should be set 1 7/8 inch (47.6mm) from its right side to the right side of the thread control plate eyelet and 1 5/16 inch (33.3mm) from centerline of its eyelet to the top of the top cover, as illustrated above.

Tension on needle thread should be just enough to pull up uniform stitches. Tension on looper thread should be just enough to steady thread.

POWER "AIR-KLIPP" CHAIN CUTTER ADJUSTMENTS

Upper knife (A, Fig. 25) can be replaced by removing two screws (B). To replace lower knife, the upper knife must be removed and rear suction tube cover. Loosen two screws (C) and slide housing (D) towards the rear. Remove screw (A, Fig. 26) and lift up thread inlet (B). Unhook knife spring (E, Fig. 25) and remove lower knife (F). Reassemble knives in reverse manner. Reassemble thread inlet (B, Fig. 26) and slide housing (D, Fig. 25) forward against rear of throat plate; tighten two screws (C).

SETTING KNIFE CROSS OVER

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

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

IMPORTANT:

Be sure that lower knife does NOT strike against knife housing or feed chamber cover. Adjustment should be accomplished by loosening two screws (G, Fig. 25) and reposition air motor (H) left or right slightly, but under extreme circumstances it may become necessary to shorten the stroke of lower knife travel by repositioning coupling (J).

Carefully press against lower knife (F, Fig. 25) until air motor stalls. With treadle still depressed, check the knife cross over. Cross over of lower knife to upper knife is positioned correctly when the lower knife is 1/32 inch (.8mm) from the front of upper knife as shown in Figure 25. If adjustment is required, loosen screw (K) and reposition coupling (J) as required to obtain specified dimension.

SHEAR ANGLE

Shear angle should be .003 inch (.076mm), measured at rear cutting edge of lower knife (F, Fig. 25) and cutting edge of upper knife (A). Adjustment can be made by loosening nut (A, Fig. 27) and turning screw (B) clockwise to increase the angle or counterclockwise to decrease. Lock nut (A) after shear angle is set.

SETTING PRESSURE VALVES

Regulate valve on pneumatic control device 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.
