4. HOW TO USE THE MACHINE
1) Threading
Raise the thread take-up lever to its highest position and pass the upper thread in the following order.
Fig.8 Fig.9
2) Adjusting of the thread regulator
The thread regulator 9 of Fig.8 ( 8 of Fig 9)regulates the amount of needle thread necessary for stitch
formation. The setting depends on the following factors: material thickness, yarn characterisation and stitch
length.
The thread regulator is fitted with slots for this purpose. Moving in the “+”direction increases the quantity
of needle thread; Moving in the “-”direction reduces the quantity of needle thread.
3) Adjusting of upper thread tension
Fig.10
The thread tension should be as low as possible. The crossover point should be in the center of the material.
Upper thread tension can be adjusted by thread tension nut 4 and 5 (see Fig.8 and Fig.9). Turn the thread tension
nut clockwise to increase the needle thread tension. Turn the thread tension nut counter-clockwise to decrease
the needle thread tension.

“up”, the roller 7 should abut on the highest point of the cam
2
The roller should not touch the cam while sewing. The
distance between roller and cam should amount to 0.1mm. Fig.38
— 18 —
Adjustment: When adjust roller to cam, first, loosen screw 5 for adjusting the distance between roller and
cam ,then twist piston rod 6 in order to adjust the distance, at last ,tighten screw 5.
Turn cam adjustment: Loosen screw 1,3 and 4 at the cam, then, twist cam 2 in such a way that the roller abut
on the highest point of the cam when the thread lever is in position “up”, at last ,tighten screws 1,3 and 4 again.
28) Adjusting the fixed knife position and bobbin thread clamping(Fig.39)
Fig.39
Checking:
The clamping spring 5 has the function to hold the cut bobbin thread in order to avoid skipped stitches at the
seam beginning.
Fixed knife 4 and driving knife 6 must be in parallel position standing under a slight cutting pressure.
Parallel position correction
Loosen screw 3 slightly for adjusting the parallel position of thread pulling knife 6 and counter-knife 4,then
change counter-knife 4 by setting the screws 2 in such a way that the edges of thread pulling knife and
counter-knife are in parallel position. Tighten screw 3 at last.
Cutting pressure adjustment
The knives should guarantee a safe cut at the lowest possible pressure of the counter-knife against the
thread pulling knife. This is normally the case when the edge of the counter-knife just touches the thread pulling
knife with a knife overlapping of 1/3.
Loosen screws1,then turn counter-knife support in such a way that the condition is fulfilled, at last ,tighten
screw 1.
Clamping adjustment
Slightly bend the bobbin thread clamp for correcting the clamping and make a test cut by hand and check
the thread clamping.

29) Safety clutch(Fig.40)
The standard safety clutch 2 in the lower toothed belt wheel protects the hook from being displaced or
damaged in case of thread jamming in the hook path. When the hook is blocked, the safety clutch 2 must come
out.
(1) Set free blocked hook.
(2) Stick a pin in drill-hole 1 of the outer clutch disc.
(3) Turn the pulley until the pin can be stuck in the
drill-holes of both clutch parts.
(4) Turn the pulley forwards and backwards until the
hook is freely movable again.
(5) Pull out pin.
(6) Hold down hook and turn the pulley until safety
clutch 2 engages.
Adjust transmittable torque Fig.40
Standard checking
The supplier by means of a torque spanner should adjust the torque transmittable from safety clutch.
(1) Loosen counter-nuts 3.
(2) Adjust torque
(3) Tighten counter-nuts 3 again.
