3.2.3 Height setting of the needle bar
At the moment, when the hook point passes around the needle,
the upper edge of the needle eye must be about 1 mm below
the hook point. In an opposite case, it is necessary to set the
height of the needle bar as follows:
Caution ! Danger of injury!
Switch off the main switch! Before starting the setting
operation, wait until the motor stops!
- Remove the front guard.
- Loosen the screw (1) of the needle bar carrier.
- Set the correct height of the needle bar and tighten anew the
screw (1).
Caution !
An incorrect setting of the needle bar height may
cause the striking of the hook point against the needle.
3.2.4 Angular setting the pin of the thread
mechanism
The hinged pin (2) of the connecting rod (3) can be set in
three positions (the pin has got 3 flats ground for the screw):
- for the hook of small diameter (value A minimum)
- for the hook of large diameter , sewing category 100 and
200 (value A = medium)
- for the hook of large diameter, sewing category 300 and
400 (value A maximum)
The value A is to be measured in the bottom position of the
take-up lever. Set the pin of the connecting rod as follows:
Caution! Danger of injury!
Switch off the main switch! Before starting the
setting operation, wait until the motor stops!
- Remove the front guard.
- Set the lowest (bottom) position of the take-up lever.
- Loosen the screw (1) of the pin (2) of the connecting rod (3).
- The position of the take-up lever is changed when turning
the pin (2).
- Set the pin (2)into the corresponding position and tighten

The correct position is given by the flat on the pin (2), on
which the screw (1) is to be tightened.
