3.7.3 Adjusting the material support arm
- Turn the main shaft until the needle tip stands 1ā2 mm behind the centre of the
presser.
- Adjust the control knob (1) Fig. 20 so that the needle is lifted by 0.2 mm, then
screw in the threaded pin (2) Fig. 20 until it lies against the case. Next, counter
the threaded pin (3) Fig. 20.
The material support arm must be adjusted to have no axial backlash.
