3.4.1
Motor drive via V-belts Tensioning the V-belt
Caution! Danger of injury!
When checking the belt tension, switch off the machine at the mains. Do not operate the machine without the belt guard. Otherwise there is a DANGER of crushing fingers, of injuries to the body and of pulling in parts of clothing.
The tensioning of the V-belt is carried out by swivelling the motor underneath the table plate after releasing the retaining nut with SW 24.
The V-belt must not be tensioned too much, especially with the stop motor. You should be able to depress it with light thumb pressure by about 2 cm.
Too little V-belt tensioning can impair the positioning of the machine and therefore impair the function sequence.
10 BA_141-30-40_A6-7_140416_en
3.4.2
Positions of the machine
CAUTION! Danger of injury!
Danger of crushing fingers and needle through stitching as well as pulling in of parts of clothing. Keep fingers and hands away from moving parts when setting the position generator and checking the positions with switched-on machine.
General:
Stop motors require a position generator, which takes the mechanical setting of the machine from the main screw and transmits this to the control of the motor. (Fig. 2)
The correct position of the position generator to the flange is marked with a spot of paint. To adjust or to remove, release the two clamping screws (2), Fig. 2. tighten these firmly prior to commissioning.
All Machines:
The machine requires two needle positions and, depending on the sewing drive, possibly also a reference position.
Reference position (if required, i.e. sewing drive DC1500-ST220A (Fig. 3)):
The reference position must be set in such a way, that the point of the needle in the direction of the insertion stitch closes with the outer table edge.
Fig. 3
11 BA_141-30-40_A6-7_140416_en
Needle position (with stop outside the seam with pedal position "-2" (Fig. 4)):
The needle position must be set in such a way, that the distance between the outer table edge in the stitch direction and the tip of the needle is about 10 mm.
Needle position is position 2 at the sewing drive.
Fig. 4
Needle position (with stop in and outside the seam with pedal position "0" (Fig.
5)): The needle position must be set in such a way, that the distance between
the tip of the needle in the stitch direction and outer table edge is about 4 mm.
Needle position is position 1 at the sewing drive.

Thread tension

Depending an quality, nature and thickness of the thread, thread tension is set by means of tension nut 279.0624 ( tight tension.
Fig. 2). A thick and strong thread requires

Setting the stitch length

ATTENTION!
Switch off machine electrically and make sure that it is really in standstill position by healing the tradle for the motor control before setting the stitch length. Otherwise danger off finger bruises and needle thoughstitches.
As shown in Fig. 7, the stitch length can be adjusted by means of stitch adjusting knob 344.0089 in the inside of the left handwheel, which is equipped with pointer 124.0080 showing through the “S” slot in the handwheel.
The handwheel has a scale according to which pointer 124.0080 has to be set. The figures of this scale do not represent a certain stitch length in mm, but
serve as reference figures only. However, low figures mean smaller stitch length and viceversa.

Inserting and re m ovi ng t he m a t e rial (Fig. 11)

ATTENTION! Danger!
The operating personnel should observe the sewing range carefully during swing. Otherwise danger of finger bruises and needle throughstitches.
When the machine is in standstill position and the needle is placed approx. 3 mm within the feed cup, by opening the front cup up to approx. 14 mm, by either actuating the treadle or the pneumatic cup opening (depending on the machine class) the sewing material can be inserted or removed easily.
Put the sewing material edge to edge and place it then up to the height limit stop of the material guide, close the front cup and start sewing.
When using a stop motor the needle is positioned automatically after the sewing process when heeling the treadle.
Only then the thread can be torn over the edge of the feed cup and then the material can be removed, or the material is removed and the thread is cut using scissors.

Machine maintenance

Attention!
Switch off machine electrically and confirm that the machine is really in standstill position by operating the treadle for the motor control. Otherwise danger of finger bruises and needle throughstitches.
The machine is maintenancefree due to automatic lubrication (see “First lubrication” point 0), only once a week dirt and hairs should be removed from oil drain hole “D” to allow the oil coming from the needle bar to drain off. Also oil splashing protector “C” should be cleaned (remove small cover at looper shaft), to avoid that the oil is soaked up by the dirt and thus spoiling the material.
Checking the oil level: Make sure that there is always
to submerge in the oil and to always bring the oil upwards. A plastic receptacle with a capacity of exactly 1 liter is supplied with the
machine. After having filled the machine with one liter oil, the oil pump’s suction piece is submerged in the oil. Oil quantity and cleanness should be checked every six to twelve month maximum.
sufficient
oil in the machine to enable the pump
If the oil is still clean enough, the oil quantity can be checked using the plastic receptacle. Drain the oil into this receptacle an re-fill it into the machine if the oil quantity is still correct. It is recommended to order a second oil container to complete the oil quantity to one liter, if necessary.
The first oil change should be realized after about six month operation.
21 BA_141-30-40_A6-7_140416_en
5.1

Oil drain pipe

To facilitate machine maintenance, at the machine body or at the lower cover respectively there is oil drain pipe 133.0764 going through the table top, thus enabling to drain the oil without removing the machine head.
The oil drain pipe 133.0764 is sealed by means of seal ring 193.0530 and screw 173.0772 (Fig. 13).
For machine assembly and for shipment the screw borings in cover 112.0085 are sealed by means of ring 193.0530 and screw 193.0772 as well as three rings 190.0010 and screws 172.0521 each (Fig. 12).
Before mounting head to the table top screws 193.0772 and 172.0521 with the seal rings have to be removed and the oil drain pipe with sealing washer
190.0178 has to be mounted and sealed (Fig. 13).
To drain the waste oil put a receptacle under the pipe and remove screw
193.0772 only. After having drained the oil screw on screw 193.0772 and seal
it. Dispose of old oil properly!
ATTENTION! Danger!
Observe safety instructions under 1.3 and operating instructions before starting any maintenance or repair works. Failure to do so can result in serious bodily injuries.
After having drained the oil rinse the machine thoroughly with petroleum and then refill with new oil.
When removing the inner cover, also oil pipe 196.0716 for the automatic lubrication which comes from the oil pump through the inner cover with oil, is removed (Fig. 6)
When re-mounting the inner cover please observe that the lower end of the main oil pipe is put into the conical opening of the oil outlet piece of the oil pump (Fig. 6). If you fail to do so the automatic lubrication does not work and the machine may be damaged seriously by jamming of the shafts in the bearings.
Therefore these instructions should be observed carefully and after refilling new oil make sure the automatic lubrication works properly by briefly operating the machine and controlling the class at the outer cover.
Before operating the machine make sure that all protection devices (e. g. cover, belt-guard, etc.) are effective and that all screws are tightened.
