Anleitung Zusammenfassung
Remove the rubber plug (A) on the top of arm and drip a little oil, then remove the rubber plug (B)and replenish sufficient amount of oil, then lift the presser foot and run the machine at a low speed of 2000 spm to check oil distributing condition through oil check window. When lubricating is normal, keep the machine run in at this speed for 30 minutes, then increase the running speed gradually, after one month run -in operation, the machine can be run at the Max speed under normal working condition. 1 .OIL FILLNG(Fig.2) 1). The oil amount in the oi! reservoir is controlled through the reference marks A and B shown in Fig2 . The mark A indicates the max. oil amount level, the mark B for the min . oil amount level . If the oil amount level is under the mark B, replenish the oil reservoir with oil in time. 2). When filling oil, loosen the oil draining screw (C), drain off the remaining oi! in the oil resrevoir completely, clean the oil resrevoir and tighten the oil draining screw (C), then fill the oil reservoir with fresh oil. 2.ROTATING HOOK OIL AMOUNT ADJUSTMENT (Fig.3) Adjust the oi! amount of the rotating hook by turning the oil amount adjusting screw (A) .Turn the screw(A) clockwise (in the * +’’ direction) to increase the oil amount; turn it counter -clockwise (in the ’ - ” direction ) to decrease the oil amount. 3.0IL PUMP ADJUSTMENT (Fig.4) In ordinary operation, adjustment is not required for the oil pump. If oil splashing does not occur in the oil check window when the machine runs at a low speed (approx. 2000 spm), close the clearance of the bypass oil hole . Adjusting plate \ \ Standard clearance 0.s-1.0mm * „ , By-pass oil hole 1 KoMnaHMfl „KpyHr" Te^./^aKc: (495) 989-22-97 4.NEEDLE INSTALLATION(Fig.5) Turning the balance wheel to lift the needle bar to the upper end of its stroke . Loosen the needle clamp screw while keeping the long groove of the needle leftward, fuily insert the needle shank up to the bottom of the needle socket, then tighten the needle clamp screw. 5.CONNECTION OF THE CLUTCH LEVER WITH THE PEDAL(Fig.6) 1). The optimum tilt angle of pedal is approximately 15 deg. 2). Adjust the clutch so that the clutch iever (C) align with the draw bar(B) as shown in Fig 6- 3). The machine pulley should rotate counter -clockwise when viewed from the outside of it. The rotating direction of the motor pulley can be reversed by turning the plug of the motor at 180 deg. 4). Adjust the tension of O -belt(F) by moving the motor up and down. The proper tension of the O 'belt is a slack of 10 -20 mm when the belt is depressed at the center of the belt by finger. 6 .BELT COVER INSTALLATION (Fig.7) Install the belt cover for the sake of safety. Install belt cover(C) to arm with screw(A) and screw (B) , and install belt cover (E) on board with screw (D). 2 KoMnaHMfl „KpyHr" Te^./^aKc: (495) 989-22-97 7.ADJUST THE OPENING TIME OF THE TENSION DISCS(Fig.8) Within the presser foot lift range , the opening time of the tension discs can be adjusted as follows: 1 ). Remove the rubber plug from the back of the arm and loosen the screw (A) of the knee lift lever (left). 2). Move the tension releasing cam (D) leftward for ear -!ier opening or rightward for later opening . it will facilitate the adjustment if putting a block under the presser foot lift. 8THREADING (Fig. 9) To thread the needle thread, raise the needle bar to the upper end of its stroke , lead the thread from the spool and perform threading as shown in Fig. 9. To draw the bobbin thread, hold the end of the needle thread and turn the balance wheel to lower the needle bar and then lift it to its highest position. Pull the ends of needle thread and bobbin thread frontward under presser foot. 3 KoMnaHMfl „KpyHr" Te^./^aKc: (495) 989-22-97 9.WINDING INSTALLATION AND ADJUSTMENT (Fig. 10) The bobbin winder putley should aiign with the V-beit and there should be some clearance between them . When the bobbin winder stop latch lever is depressed, the V-belt should be in touch with the bobbin winder pulley in order that the bobbin winder puller can be driven by the V-belt. The thread wound on the bobbin should be neat and tight, if not tight, adjust the winding tension by turning the tension stud nut (A) of the bobbin winder tension bracket.When the thread wound on the bobbin dose not present a cylindrical shape as shown in Fig. 10(a), loosen the set screw (B) of the bobbin winder tension bracket and move the bracket (C) leftward or rightward. If the thread is wound as shown in the figure (b), move the bracket rightward or if wound as shown in the figure (c). move it leftward. After positioning the bracket adequately, tighten the set screw (B). Do not overfill the bobbin. The optimum wound length of the thread will fill about 80% of the bobbin capacity. This can be adjusted by the screw (E) of the bobbin winder stop latch. 10 © o o © v. 10. ADJUST THE PRESSURE OF PRESSER F...
