3.5.2.3b Forward and rearward stitch length
distribution (fine)
When setting the maximum length of the stitch, the forward and
the rearward stitch length must be equal with the maximum error
of ± 5 %. This setting can be done only after having set the needle
feed (par. 3.5.3) and the wheel feed (par. 3.5.4.1.2).
Caution! Danger of injury!
switch off the main switch! Before starting the setting
operation, wait until the motor stops!
- Set the maximum stitch length .
- Place a suitable material under the presser foot and mark therein
the forward and the rearward stitch length.
- With an unequal length of the stitch, proceed to the correction
of setting by turning the screws (2 and 3). When tightening the
screw (3), the forward length of the stitch is shortened and
inversely. When tightening the screw (2), the forward stitch
length is lenghtened. Tighten the screw (2).
3.5.2.4 Setting the control knob (including the stitch
length limitation).
The control knob (1) is to be set up in such a way that, when
turning it in counterclockwise sense up to the stop, the maximum
stitch length valid for the given sewing category is attained
(cat. 1: 3 mm, cat 2: 5 mm, cat. 3 : 5 mm). The scale of the
control knob is to be oriented in such a position, so that the scale
end corresponds to the maximum stitch length, excepting the first
sewing category, where the stitch length of the indicator is 3 mm.
Caution! Danger of injury
Switch off the main switch! Before starting the setting
operation, wait until the motor stops!
- Screw in the screw of the control knob in such a way that the
ball of the screw (3) bears on the seat of the cam (4).
- Loosen the screw (5) and turn the control knob in the clockwise
direction, until the pin (6) of the knob (1) bears on the pin
(7). Tighten firmly the screw (5).
- Turn the knob in the counterclockwise direction up to the stop,
when the pin (6) of the knob (1) bears on the pin (7).
- In a sewing test check up the length of the stitch, if this
corresponds to the maximum stitch length valid for the given
sewing category.
- If the stitch is longer, loosen then the screw (5) and turn the
knob in the clockwise direction and inversely. Tighten firmly the
screw (5)
- Insert a screwdriver into the hole (8) of the scale (2) and adjust
the scale in such a way that the maximum length on the
scale is against the marking of the stitch length on the
machine arm.
- For the sewing category 1, set the control knob (1) on the
stitch length of 3 mm and check it by a sewing test.
- Loosen the screw (5) and turn the control knob (1) in the
counterclockwise direction, until the pin6) of the knob (1)
bears on the pin (7). Tighten firmly the screw (5).
