13) SETTING THE PRESSER FOOT STROKE
Sewing machines GF-137/237-series are always equipped with 2 dials for setting the
presser foot stroke.
Left dial 2 controls standard presser foot stroke in the range of 1 to 9mm.
Right dial 1 controls increased presser foot stroke in the range of 1 to 9mm.
- Turn the dials 1 and 2 (value 1-9)
1 = minimum presser foot stroke
9 = maximum presser foot stroke
Presser foot stroke and number of stitches are interdependent.
The potenciometer is mechanically connected with the dials and the control unit can
thus recognize the set presser foot stroke, limiting the sewing speed (number of
stitches) automatically.
The machine is equipped with the system of quick electropneumatic setting of
presser foot stroke.
When cross seams or heightened/reinforced points of material are sewn, increased
secondary presser foot stroke (dial 1) can be activated by pressing the knee lever 3.
Note – standard presser foot stroke set by the dial 2 must not have higher value than
increased presser foot stroke set by dial 1.
