16 To adjust the counter knife (Fig. 14)(table I1,I2,J-Parts Book)
Counter knife (I1/7) is located on the holder (I1/3).
After releasing the screw (I1/19), mildly push the counter knife (I1/7) on the moving knife
(I1/20) by the means of the excentric pin (I1/9) which means in the following position : counter
knife blade must come into the contact approx.5 mm distance from the front of the moving
knife (I1/20). In this position the pressure is secured by the screw (I1/19). For ensuring the
reliability and long service life of thread trimmer mechanism´s parts it is important to secure
the thread cutting with minimal pressure strength of counter knife (I1/7) on the moving knife
(I1/20).
With each adjustment of the pressure check out by manual cutting of two threads inserted into
the gap of the moving knife and by the movement against the counter knife check up their
corect cut out.
By this adjustment the screw (J/27,I2/43) on the bracket (J/11,I2/42) is released.

17 To adjust the clamp spring (table I1,I2 – Parts Book)
Position of the clamp spring (I1/8) adjust using the screw (I1/28) in the holder (I1/3).
Move the clamp spring so that it is slightly in contact with the moving knife (in direction of the
arrow – Fig. 13 )
Manually actuate thread trimming to check that the bobbin thread is clamped.
RESULTS OF IMPROPER ADJUSTMENT
If the pressure of clamp spring is to big :
- Length of thread remaining on the material after thread trimming will be lengthened,
the sewing start is wrongly attached.
- The moving knife may be locked.
If the clearance between the moving knife and the clamp spring is larger than the specified value
:
- Clamping failure or stitch skipping at the sewing start may result.
