Häufig gestellte Fragen - CF2339M-1 Yamato

Wie wird die Nadel eingefädelt?

Schalten Sie vor dem Einfädeln immer den Motor aus und stellen Sie sicher, dass der Motor gestoppt ist. Fädeln Sie die Nadel wie in Abbildung 5 gezeigt ein. Für die linke Nadel in der innersten Position bitte die Anweisungen in Abbildung 7 beachten. Bei Verwendung von Wollgarn das Einfädeln gemäß Abbildung 6 durchführen.

Wie wird das elastische Band eingelegt?

Drücken Sie den Rollenhebel (1), um einen Spalt zwischen den Rollen zu schaffen. Ziehen Sie das Band durch die Unterseite des Nähfußes (2). Richten Sie das Band gemäß Abbildung 10 korrekt aus.

Wie wird die Zufuhrmenge des elastischen Bandes eingestellt?

Lockern Sie die Mutter (1) und drehen Sie die Einstellschraube (4), um die Zufuhrmenge zu ändern. Drehen Sie im Uhrzeigersinn, um die Zufuhrmenge zu erhöhen (Zeiger in Richtung "L") und gegen den Uhrzeigersinn, um sie zu verringern (Zeiger in Richtung "S"). Ziehen Sie anschließend die Mutter fest.

Wie wird die Schneidbreite eingestellt?

Öffnen Sie die Seitenabdeckung und lockern Sie die Schraube (1). Der Ober- und Untermesserhalter bewegen sich gleichzeitig nach links und rechts. Ziehen Sie die Schraube nach der Einstellung fest. Geben Sie bei Bedarf ein paar Tropfen Öl in das Ölloch (2).

Wie wird die Messvorrichtung geschmiert?

Entfernen Sie die Schrauben (7) an der Rollenwelle und schmieren Sie mehrmals im Jahr die Teile mit Fett. Stellen Sie sicher, dass die Rollenwelle leichtgängig läuft und die Spannrolle (klein) sich frei dreht.

Wie werden die Ober- und Untermesser ausgewechselt?

Zum Ausbau des Untermessers: Lockern Sie die Schrauben (1) am rechten Bund, drücken Sie den linken Bund (2) nach rechts, um einen Spalt zu schaffen, ziehen Sie die Schrauben leicht an, lockern Sie die Schraube (3) und ziehen Sie das Untermesser heraus. Zum Einbau: Positionieren Sie die Spitze des Untermessers bündig mit der Oberseite der Stichplatte und ziehen Sie die Schraube fest. Für das Obermesser analog vorgehen. Überprüfen Sie die Schärfe, indem Sie einen Faden zwischen die Messer legen und die Riemenscheibe drehen.

Wie wird der Stoffabschneider gewartet?

Der Stoffabschneider (Trimmer) besteht aus Ober- und Untermesser. Stellen Sie die Messer wie in Abschnitt 4.6 beschrieben ein. Das Untermesser kann bei Bedarf nachgeschliffen werden (siehe Abbildung 22). Das Obermesser aus Hartmetall muss etwa ein Jahr lang nicht geschärft werden. Wenden Sie sich bei Bedarf an den Händler.

Was ist die maximale Nähgeschwindigkeit?

Die maximale Nähgeschwindigkeit beträgt 5000 U/min, die Standardgeschwindigkeit beträgt 4500 U/min. Für eine lange Lebensdauer sollte die Maschine in den ersten 200 Stunden bei 4300 U/min betrieben werden.

Welches Öl wird für die Schmierung benötigt?

Verwenden Sie ausschließlich YAMATO SF OIL #28. Die Schmierung erfolgt automatisch durch eine Pumpe. Der Ölbehälter fasst 1100 ccm.

Wie wird der Nähfuss angehoben und eingestellt?

Der Presser Foot Lift (parallele Einstellung des unteren Nähfusses) beträgt 4,0 mm mit Spreizer. Die Einstellung erfolgt über die entsprechenden Schrauben. Achten Sie darauf, dass der Nähfuss korrekt ausgerichtet ist, um einen gleichmäßigen Stofftransport zu gewährleisten.

Before operating, ALWAYS turn the motor switch OFF and check that the motor has already stopped.

Set the needle thread retainer disc to the needle clamp on this machine.

Thread through the needles as shown in Fig. 5.

When not threaded, thread correctly as shown in Fig. 7. When threaded, rethread after knotting preset threads.

A: Needle thread

Pull out the thread until it is in front of the needle. Then cut off the knot before needle eye to rethread.

Thread correctly for the left needle in the inmost position as shown in Fig.7.

B: Top cover thread

Pull the thread until the knot is out.

C: Looper thread

Pull the thread until the knot is out. Then cut off the knot.

Tighten needle thread, when light material is sewing. The following thread as shown in a right Fig. 6.

WARNING

Before adjusting, ALWAYS turn the motor switch OFF and check that the motor has already stopped.

4.1 Chip guard and presser foot tape guide

Adjust the lace guide(left)① right or left depending on the needle distance and a part to be sewn on a tape.

Set the lace guide(right)② depending on a tape width.

Loosen the screws ③④ to adjust them.

Set the chip guard ⑤ depending on a trimming width.

Loosen the screw⑥ to set it near the upper knife as closely as possible.

4.2 Tape guide

(1) Set the tape guide bar(long)⑦ to a low position enough for sewing.
(2) Set the inside of the tape guide, c. set⑧ along “A” on the lace guide(left)⑨. Set the tape guide ⑩ to guide a tape smoothly depending on a tape width.
(3) After positioning the tape guide bar(long)⑦, loosen the screw ⑪ to position the tape guide stopper ⑫.

It prevents the needle bar from touching the tape guide, c. set ⑧ and makes the position of the tape guide bar (long) ⑦.

WARNING

Before adjusting, ALWAYS turn the motor switch OFF and check that the motor has already stopped.

4.3 Pressure of elastic feed roller

To adjust the pressure of elastic tape with tension roller (small)①, loosen the lock nut② and turn the adjusting screw ③.

● To increase the pressure, turn the adjusting screw ③ clockwise.
● To decrease the pressure, turn it counterclockwise.

Keep the pressure as low as possible.

Too tight or loose pressure can cause uneven feeding of a tape.

REFERENCE

Too much change in tension of a tape from the bobbin may occur uneven sewing finish size even if the tension roller(large) feeds an elastic tape correctly.

An automatic elastic feeder "AEF-31" can feed an elastic tape smoothly and constant sewing finish can be obtained.

4.4 Maintenance of metering device

Replacement and repair:

Improper installation of the metering device can cause improper feeding of an elastic tape, skip stitch, needle breakage, bad sewing performance and others.

Carefully install the device as following points:

(1) Check that the roller shaft turns smoothly after setting it. Loosen the screws ④ and ⑤ and make interlining to adjust it.
(2) Set the tension roller(small)① to turn smoothly like a top. Improper turning of it can cause irregular feeding of a tape.
(3) Set the tension link ⑥ and its shaft to turn smoothly.
(4) Set the tension spring pressure of the tension roller (small)① as low as possible so that it can follow the rotation.

Lubrication:

Remove the screws⑦ on the roller shaft to supply with grease on each part several times a year.

4.6.4 Sharpening knives

If the lower knife cuts badly, re-sharpen it. (See Fig. 22)

The upper knife made of super hard alloy is unnecessary to re-sharpen for about one year and normal grinder is not useful for re-sharpening it.

Keep another upper knife for spare.

If needed, contact us directly or the dealer for re-sharpening it.
