10/10/5 Setting the tension release
10/10/6 Set knife pressure
The tension discs (1) (Illustration 2) should be about
0.5 to 1.0 mm apart when the lever (A) (Illustration 2) is
at the left position.
1. Turn the hand wheel until the needle is coming up from
the lower turning point and the point of the needle is in
line with the needle plate. Move the lever (A) (Illustration
2) to the left to initiate cutting operation. (Secure lever in
this position)
2. Loosen the counter nuts (2) (Illustration 1) and turn until a
distance of 0.5 to 1.0 mm is achieved.
3. Tighten counter nuts (2).
The knife pressure should be as low as possible but the thread
must be cut securely. Low knife will result in less wear and
tear on the parts.
1. Turn the screw (A) (Illustration) clock wise for more
pressure and anti-clock wise for less pressure
