Adjusting thread tensionIn principle the thread tension is to be adjusted inaccordance with materials, thread and other factors.In practice, the thread tension is adjusted accordingto the stitches resulted. The needle thread tensionshould be adjusted with referensce to the bobbin threadtension.To adjust the bobbin thread tension, turn bobbincase tension spring screw A (see Fig.21) clockwise toincrease the tension,or turn the screw counter-clockwiseto decrease the tension.10

It is a common practice to check the bobbinthread tension as shown in Fig. 22. In case of glazedthread #50, hold the end of pulled out thread and tovibrate bobbin case up and down, if the bobbin casefall down slowly, the proper tension is obtained.The needle thread tension can be adjusted bychanging:(1) tension of the thread take-up spring,(2) swinging range of the thread take-up spring,(3) tension of tension disc(4) the position of thread guide 6 in fig. 17. Allthese adjustments will be described as follows.ABBobbin225.1. Adjusting the thread take-up springThe normal tension of thread take-up spring is approx.35-55. The normal swing range of the thread take - upspring is 5-8mm. For sewing light weight materials (withshort stitch length), weaken the spring tension and widenthe swinging range of spring, while for sewing heavyweight materials, strengthen the spring tension andshorten the swinging range of spring.5.1.1 Adjusting the thread take-up spring tension(Fig.23)Loosen tension stud set screw A, turn tension stud Bclockwise to increase the spring tension, or turn thetension stud counter-clockwise to decrease the springtension. After the adjustment, be sure to tighten tensionstud set screw A.The thread take-up spring tension is about 45g. Toattain this, loosen set screw A first, then turn tension studB counter clockwise to release the tension of thread takeupspring C to zero, and turn tension stud Bclockwise until spring C just comes into contact with thestopper on thread take-up spring regulator, then furtherturn tension stud B clockwise be 1/2 turn. After adjustme-nt, tighten tension stud set screw A.5.1.2 Adjusting the swing range of thread take-upspring (Fig.24)Loosen set screw B, turn tension complete Cclockwise to increase the swing range or turn tensioncomplete C counter-clockwise to decrease the swingrange. After the adjustment, tighten set screw B.Before delivery, thread take-up spring is properlyadjusted. Re-adjustment is needed only in the case ofsewing special material material or with special thread.5 ~8mmBCCBA232411

When adjusting,loosen nut with a spanner first, then move the presser foot liftregulating screw to change its center distance B between thepresser foot lift shaft, as shown in Fig.39 The lift amount isincreased as to shorten the center distance B, and the liftamount is decreased when widen the center distance B,After adjustment, tighten the nut again.4) Adjusting the clearance betwesser foot and walkingpresser footIn sewing operation, for prevent the walking presser footfrom striking on presser foot at the end of feeding, a properclearance C of approx. 1.5mm should be maintained betweenthem, as shown in Fig.40b. When the clearance is too smallor too big necessary to adjust, loosen rear crank clampingscrew with a screw driver and turn the rock shaft, sa shown inFIG.40A. Turn rock shaft clckwise to decrease the clearance C,and turn the rock shaft counter clockwise to increase theclearance C. After adjustment, tighten clamping screw.After the adjustment of 2).3) or 4) as mentioned above, aninspection should be made, as to raise the presser feet withpresser bar lift, and turn balance wheel slowly to see that thewalking presser foot is to strike with other parts, if it is, shouldbe adjusted again.AboveUnderNutPresser footlift front crank37b6.5.2 Adjusting the feed mechanism of machine Model GC6-71) adjusting the feed amountTop feed must be synchronized with needle feed andbottom feed, this is performed in factory before delivery. Ifnecessary it can be adjusted as follows:Lift the presser foot with presser bar lifter, set the maxstitch length, then turn balance wheel slowly and watch forneedle penetration to see if the needle is positioned in thecenter of feed dog needle hole, at the point B as show inFig.38, if not, should be adjusted first as shown in Fig.40a.After adjustment, tighten the clamping screw.Turn the balance wheel continuously until the needlefeed end is reached, at that time, the feed amount is correctwhen the needle is still positioned in the center of feed dogneedle hole, at the point B1 as shown in Fig.38. If theneedle is positioned at point A in Fig.38, the feed amount istoo big, and too small of feed amount while the needle ispositioned at point C in Fig.38, all of these should beadjusted accordingly. In adjusting, loosen nut with a spanner,then to change the center distance A, after adjustmenttighten the nut.ForwardABCBStitch lengthNeedle3817

B2) Adujsting the alternate lift amount of the presser feetLift amount of the walking presser foot is within 5mmand lift amount of the presser foot is 2.5 mm, when sewingmedium or heavy materials. The lift amount of these twopresser feet can be changed slightly according to the natureof material or the requirements in sewing. The sum of thelift amount of these two presser feet is nearly the same asthe other mechanisms are kept in constant condition .Inother words, the increasing of walking presser foot liftamount diminishes the lift amount of presser foot, and viceversa.When adjusting, loosen the presser foot lift front crankclamping screw slightly with a screw driver as shown inFig.37b, and turn the crank to overcome the friction on itsshaft. The lift amount of walking presser foot can beincreased and the lift amount of presser foot is decreased ifturn the crank clockwise. The lift amount of walking presserfoot is decreased and the lift amount of presser foot isincreased when turn the crank counter-clockwise. Afteradjustment, tighten the clamping screw.3) Adjusting the lift amount of presser foot together withwalking presser footThe lift amount of presser foot together with walkingpresser foot can be adjusted slightly. When adjusting, loosennut with a spanner foot lift regulating screw to change itscenter distance between the presser foot lift shaft as shownin Fig.39. The lift amount is increased as to shorten thecenter distance B, and the lift amount is decreased when towiden the center distance B. After adjustment, tighten thenut again.4) Adjusting the clearance between presser foot andwalking presser footIn sewing operation, for prevent the walking presser footfrom striking on presser foot at the end of feeding, a properclearance C of approx. 1.5mm should be maintained betweenthem, as shown in Fig.40c. When the clearance is too smallor too big necessary to adjust, loosen rear crank clampingscrew with a screw driver and then turn the rock shaft asshown in Fig.40a. Turn the rock shaft clockwise to increasethe clearance C, and turn the rock shaft counter-clockwise todecrease the clearance C. After adjustment, tighten theclamping screw.After adjusting the clearance between presser foot, it isprobable the needle to deviate from the center of the feeddog needle hole in feed direction, this can be adjusted toloosen the feed rock shaft crank clamping screw B (Fig.34b) and shifting the feed dog B (Fig.40d) in direction offeed after adjustment, tighten clamping screw B again, Incase the needle is deviated from the feed dog needle holecenter in the crosswise direction, loosen twoo feed dog screwA (Fig.40d) and to shift the feed dog B crosswise. Afteradjustment, tighten the feed dog screw.After the adjustment of 1)-4) as mentioned above, aninspection should be made, as to raise the presser foot withpresser bar lifter and turn the balance wheel slowly to seethat the walking presser foot is to strike the other parts.
