2. Main specifications 1. Brief introduction Machine adopts compound feed and special feeding mechanism, which can ensure smooth feeding, low noise, and beautiful stitch seam. It is constructed with slide link thread take-up, horizontal large rotating hook, and synchronized belt driving system, which ensures high speed, but lower noise. Application Max. sewing speed Max. stitch length Medium and heavy duty 2000 s.p.
2 4. Installing the oil pot (Fig. 2) ④⑤ Oil reservoir ⑧ 1.Install the bolt ①, oil seal ② and spacer ③ onto the oil reservoir, and then put the cushion ⑤ and spacer ⑧ into the set screw ④, then set it by nut ⑥. 2.Tighten the oil pot ⑦ onto the bolt ①. ⑤ ③ ⑥ ⑦ ② ① 3 5. Adjusting the tension of the belt (Fig.3) When adjusting the tension of the belt, please adjust the height of the motor, and press down the middle of the belt with the force of 9.8N. There should be a slack of 15mm.
7. Lubrication (Fig.5) ① 1.Face plate lubrication a.Loosen the face plate screw; b.Open the face plate ① in the direction of the arrow; c.Lubricate the place as the arrow shows every day; d.Close the face plate; e.Tighten the screw. 2.Machine body lubrication a.Lubricate the place as the arrows indicate every day; b.When run the machine for the first time or run it again after a long period of non-use, please oil the place as the arrows indicate.
9. Threading the bobbin thread (Fig.7) ① 7 1.Insert the bobbin into the hook body, pass the thread through the thread hole ①, then pass down through the thread tension spring ②. 2.Draw the thread downward, then the bobbin will turn in the direction as the figure shows. ② 8 10. Installing the bobbin case (Fig. 8) 1.When taking out the bobbin case, open the gib ① and pull it off. 2.Align the bobbin case with the rotating hook shaft and then insert it.
11 13. Threading (Fig11) Thread in the order as shown in Fig. ② ⑨ ① ⑧ ③ ④ ⑩⑦ ⑤ ⑥ 12 14. Adjusting the stitch length (Fig.12) Turn the stitch length dial plate ① leftward and rightward to make the marker align with the required figure. Press down the reverse feed lever ② to start backward sewing, and release it to start normal sewing. ② ① 13 15. Adjusting the thread tension (Fig.13) 1.
14 16. Adjusting the thread take-up spring (Fig.14) ⑤ 1.Changing the swing range of the thread take-up spring a.Loosen the set screw ②, move the stopper ③ leftward and rightward, then adjust the thread take-up spring ①. b.Move the stopper rightward to increase the swing range of the thread take-up spring; on the contrary, to reduce the swing range of the thread take-up spring. 2.
18 20. Adjusting the alternating amount of presser foot (Fig.18) ① When the presser foot is alternating increasingly, adjust it upward in the range of the long hole of the top feed crank ③; when the presser foot is alternating decreasingly, adjust it downward, then tighten the nut ②. When the lifting amount of the presser and walking foot is different, first align the bottom of the presser foot and walking foot with the surface of the needle plate, then loosen the set screw ①.
