Lubrication of machine:
1. Fill oil pan ①with supplied oil up to the level between marking MAX and MIN Ⓐ.
2. If the level of oil goes below MIN, refill the oil pan up to the level between marking MAX and MIN.
3. When you operate the machine after lubrication, you will see splashing oil through oil sight
window ②if the lubrication is adequate. If the machine runs in low speed, splashing oil is not seen
(the pump cannot create sufficient pressure). For this reason, when operating the machine in lower
speed, press the pedal to maximum occasionally to make the pump push the oil up to the upper
shaft making the splashing oil visible in the oil window ②.
4. Amount of splashing oil is not proportional to the amount of oil in the pan
Caution:
Turn off the main switch before the operation.

Lubrication of rotating hook
Adjustment method:
1. Set the lubrication of the rotating hook by adjusting screw ①. By turning the screw clockwise
amount of oil will be increased, by turning the screw counterclockwise the amount of oil will be
decreased. In order to achieve correct setting, adjustment can be done repeatedly.
2. Check the lubrication amount again after approximately 2 hours of machine operation.
3. Correct adjustment results in decrease of the machine noise and longer operational life of the
hook. Excessive lubrication can stain the sewn material. The amount of coming oil depends on
maximum speed of the machine. If the maximum speed level is changed, it is necessary to check
correct setting of hook lubrication again.

1. Insert bobbin in bobbin winder ① and
push it.
2. Lead the thread through the tensioner
and then wind it around the bobbin
according to picture.
3. Push the stopper ③towards the shaft
with bobbin ②. If the pedal is pressed
during machine operation, thread winding
is initiated and bobbin is rotating in
direction of Ⓒ. When the winding is
completed, the process is automatically
stopped and the shaft clicks away from
the stopper ③. Caution: during winding
process the needle and thread take-up
lever are always in motion, for this reason
wind the bobbin thread only during the
stitching process, otherwise it is
recommended to take out the thread
from needle and thread take-up lever.
4. If you want to stop winding before the bobbin is full, stop the machine, move the stopper ③away
from the shaft ②and take out the bobbin.
5. Position of stopper ③ regulates amount of thread to be wound. For adjustment loosen the screw
⑤and move the stopper ③in the direction of Ⓐor Ⓑ. Then tighten the screw ⑤. Direction of
Ⓐ: to reduce the amount of thread, direction of Ⓑ: to increase the amount of thread.
Ideal adjustment is if the thread is approximately 1 mm from the edge of the bobbin. If the thread
goes over the edge of bobbin, it is impossible to insert it into bobbin case.
6. Thread should be evenly wound. If
not, it can make it impossible to
reach correct stitch composition
stretching the thread up or down
unevenly. Adjustment is made by
correction of thread tensioner height
and its discs.⑦. Loosen the nut ⑥
and correct the height of the
tensioner by rotating until the
bobbin winding corresponds to the
middle picture. Then tighten the nut
⑥. By loosening and tightening the
nut ⑧tension of the thread on
bobbin can be adjusted. If the
tension is too high, the bobbin can
be deformed. If the tension is not
sufficient, the thread can be tangled.
