OPERATION INSTRUCTION

1. Brief introduction2. Main technical specificationsTW1-1245 adopts compound feed mechanism withsynchronous top, bottom and needle feed and themax amount of alternating presser foot lifter reaches7 mm, which guarantees the high sewing quality ofdifferent materials. Besides, TW1-1245 adopts thelarge auto-lubricating horizontal rotating hook,4-link thread take-up lever and timing belt, whichassures its lower noise and high speed.This machine is widely used in manufacturingsuitcase, tents, cushions, lenther products, clothesbamboo matting, etc.ApplicationsMax.

8. MaintenanceClean the bobbin clearanceNormal oilingFront parts oilingCheck the hook oil boxClean the rotating hookUpper feed driving eccentric oilingOnce a weekTwice a weekTwice a weekOnce a weekOnce a weekonce a yearThe above data is due to the normal situation.If the machine is used frequently, the interval of themaintenance should be shortened.Maintenance for rotating hook(Fig.6)1. Clean the rotating hook with brush every day,and constant use needs more frequent cleansing.2. Clean the rotating hook thoroughly every week.As follows:a. Open the slide plate and lift the needle bar to itshighest point;b. Take out the bobbin cap and the bobbin;c. Release the hook gib 1; turn over the balancewheel until the Point 2 passes to the groove 5mm;then take out the bobbin case;d. Clean the rotating hook track with paraffinwax;e. When the bobbin case is installed, the horn 5and needle plate groove must be closely touched;(Fig. Arrow)Tighten the hook gib 1, install the bobbin caseand close the slide plate.679. Oiling(Fig.7)The machine must be oiled at the mark(arrow)twice a week.3

810. Lubricating the hook(Fig.8)1. Pull out the knee lever, then lay down themachine head;2. Fill the oil into box 1 through the hole 2 untilthe oil level exceeds the highest level mark;3. Raise the machine.911. Lubricating the machine head (Fig.9)1. Open the face plate;2. Oil twice a week at all the moving position asthe Fig shows;3. Close the face plate.1012. Lubricating the upper feed driving eccentric(Fig.10)1. Open the rear cover 1;2. Oil the interface (2) at least twice a year;(apply to oil gun)3. Close the rear cover.4

13. Adjusting the feed dog111. Positioning the feed dog across the direction ofsewing(Fig.11);a. Loosen the screw 1 and 2;b. Adjust the shaft 3 as required;c. Tighten the screw 1. (Keep the screw 2 looseningfor the following adjustment)The bottom feed dog must be the same distancefrom the left and right side of the needle plate cutout2. Positioning the feed dog in the direction of sewing(Fig. 12)a. Set the longest stitchb. Adjust the shaft 1 as required, and tighten thescrew 2.With the longest stitch set, the bottom feed dogmust have the same clearance the front and the backwith respect to the needle plate cutout when feedingboth forwards and backwards.123. Adjusting the height of feed dog (Fig.13)a. Adjust the stitch length to 0 ;b. Turn over the balance wheel until the feed dogreaches its highest position; and as required, adjust thefeed dog supporter 1 and the screw 2.135

1414. Pre-adjusting the needle height(Fig.14)Move the needle bar 1 (screw2) up and down, andas required, adjust it to the right position.When the needle bar is at the lowest position,theclearance between needle bar and needle plate shouldbe 15 cm.1515. Centering the needle in the needle hole(Fig.15)1. Loosen the walking foot 1 and the presser foot 2;2. Adjust the stitch length to 0 , and lift theneedle bar to its highest point;3. Insert the new needle, and loosen the screw 3,4,5,6;4. Turn the balance wheel and pass the needledirectly through the feed dog;5. As required, move the needle bar frame 7;6. Tighten screw 3,4,5,;7. Move the pin 8 to make it touch the needle barframe 7, and tighten screw6.When the stitch length is at the 0 ,the needlemust enter the needle hole exactly in the middle1616. Adjusting the bottom feed dog position(Fig.16)1. Adjust the needle bar to the lowest position;2. Turn the eccentric wheel 1(screw 2) , and adjustthe bottom feed dog to the highest position;3. Tighten screw 2 to make the eccentric wheel 1unable to turn;4. Set the stitch length to the max and turn theeccentric wheel 1 a bit in accordance withrequirement 25. Tighten screw (2).a. When the needle bar is at its lowest position,the bottom feed dog should be at the highest position;Set the stitch length to its max; turn the balancewheel, and when t he bottom feed dog and the needleplate are in the same horixzontal level, the point ofthe needle should be right reaching the surface ofthe needle plate.6

17. Adjusting the upper and the lower feed (Fig.17)171. Adjust the stitch length to the max;2. Loosen screw 1 to make the feed eccentricwheel 2 turn around the shaft;3. Adjust the needle bar to the lowest position;4. Turn the eccentric wheel 2 so that its eccentricityis facing downwards.5. As required, turn the eccentric wheel a bit as itturns and tighten screw 1;6. Check it as required.When the stitch lenght is at the max, the needlebar is at the lowest positon, if the reverse feed leveris activated, there will be no feeding.18. Position of needle and rotating hook(Fig.18)1. Adjust the stitch length to 3 , and loosenscrew 1,2;2. The clearance between needle and the hookpoint should be adjusted to 0.05-0.1 mm by movingthe hook gear 4;3. Tighten screw 1;4. Turn the needle to the lowest position, andcontinue to turn the hand wheel to raise 2 mm of theneedle;5. Make the hook point aim at the center,of theneedle and be sure the guard plate 7 doesn t press onthe needle;6. Leave some gear clearance and tighten screw 2;7. The vertical clearance between the top ofneedle eye and the hook point should be 0.8-1 mmby adjusting the needle height;8. The guard plate 8 might be adjusted to touchthe needle lightly.When the stitch length is adjusted to 3 andthe needle is lifted 2 mm from the lowest position,the follwing requirements must be reached:a. The clearance between needle and hook pointis 0.05-1mm;b. The vertical clearance between the top ofneedle eye and hook point is 0.8-1mm;c. The guard plate must touch the needle lightly.181919. Adjusting the lifting amount of alternating presser foot(Fig.19)1. The stitch length is adjusted to 0 , and thelifting amount of alternating presser foot is adjustedto the max;2. Lower the presser foot 1 on the needle plate;3. Turn the hand wheel until the walking foot 2reaches the highest position;4. As required, move the crank 3 (screw4);5. Check as required.When the stitch length is at the 0 and thelifting amount of alternating presser foot is at themax, turn the hand wheel to make sure the clearacebetween presser foot 1/ walking foot 2 and needleplate is 7mm .7

2020. Top feed adjustment (Fig.20)1. Lower the presser foot on the needle plate;2. Loosen screw 2 until the feed lifting eccentricwheel 3 can turn reluctantly;3. Adjust the eccentric wheel 3 as required;4. Tighten screw 2;5. Check as required.When presser foot is resting on the needle plate,the walking foot and the point of needle must bothreach the needle plate at the same time when the topfeed stroke is set at maximum.2121. Adjusting the bobbin case opener1. Thread the machine; lay down the material; thenlower the presser foot;2. Turn the hand wheel and sew a bit, then check asrequired.3. Move the opener 1 (screw 2) as requiredThe needle thread must not be clamped whenpassing through the mark 1,3,42222. Saftety clutch (Fig.22)1. When the rotating hook jams the thread, thesafety clutch will be off to prevert the hook beingdamaged2. Take out the jammed thread;Press the piston 1 and turn the hand wheel untilhook 3 of pawl 2 clicks into groove 48

23. Needle thread tension release (Fig.23)23When the presser foot is lifted, the clearancebetween the two tension discs should be 0.5mm( 0.5mm is the minimum. When applied to thickthread, it could be adjusted to 1 mm or more).Adjustthe plate 1 as required.24. Bobbin thread winder (Fig.24)181. When the winder switch on, its spindle mustengage reliable; when the winder switch off, thefriction wheel 5 and the driving gear 1 should getapart;2. When the thread level is approx. 1mm from theedg of the bobbin, the winder will switch offautomatically;When operating, set the bobbin on the winder,threading the bobbin thread and switch the winderOn, adjust the pin 3 and screw 4 as requirementsif need.9
