The right adjusting wheel (2) determines the elevated sewing foot
stroke. It is used for example when sewing thicker parts of the
material.
Figure 20: Knee lever
The elevated sewing foot stroke is activated using the knee
lever (1). There is a switch (2) at the back of the knee lever (1),
which determines whether the sewing foot stroke is applied
continuously or only as long as the knee lever is pressed.
For permanent conversion:
1. Turn the switch (2) up.
2. Press the knee lever (1) to the right to switch on the elevated
sewing foot stroke.
3. Press the knee lever (1) to the right again to switch off the
elevated sewing foot stroke.
For temporary conversion:
1. Turn the switch (2) down.
2. Press the knee lever (1) to the right and hold it in position to
switch on the elevated sewing foot stroke.
The elevated sewing foot stroke is retained as long as the knee
lever is pushed to the right.
3. Release the knee lever (1) to switch off the elevated sewing
foot stroke.
The elevated sewing foot stroke must not be lower than the normal
sewing foot stroke. Always set the sewing foot stroke at the right
adjusting wheel in such a way that it is at least as high as the
sewing foot stroke at the left adjusting wheel.
