4.7
By stitch depth one understand the distance of the highest plunger position to
the outside radius of the needle, the plunger presses the sewing material from
underneath in the stitch plate opening, so that the needle stitches into the fabric
layers at the required depth.
Stitch depth
Low stitch depth: the needle penetrates less deep into the fabric layers
of the sewing material.
Large stitch depth: the needle penetrates deeper into the fabric layers of
the sewing material.
With too low or too large a stitch depth, omissions or through-stitches can
occur.
4.7.1
With the aid of the stitch depth regulating button 444.0322 (
Adjusting the stitch depth (Fig. 2 and Fig. 6)
Fig. 1) on the lower
arm on the right, the plunger can be lifted or lowered dependant on the
thickness of the fabric. Above this regulation button is a plate which shows how
the button must be turned so that the plunger is lowered or lifted.
Turning the button to the right – plunger goes upward, needle penetrates
deeper.
Turning the button to the left – plunger goes downward, needle
penetrates less deep
See also “4.7.2 Digital stitch depth display (Fig. 13)”.
The stitch depth for the side plunger is adjusted with the knurled screw
177.0418 (Fig. 6) on the left above the stitch plate.
Turning to the front (clockwise) – needle penetrates deeper
Turning to the back (anti-clockwise) – needle penetrates less deep.
4.7.2
The plunger height can be read off digitally from the stitch depth display. This
makes finding earlier adjustments substantially easier by frequently changing
sewing material thickness.
Digital stitch depth display (Fig. 13)
The current supply is via a 9 V battery in the housing. To prevent premature
discharging of the battery, the display should be switched off with the toggle
switch at the housing during longer work breaks and when finishing work.
The unit shows a hundredth of a mm, the hundred position a full rotation of the
regulating button.
Always valid: Small number - thin sewing material
Large number - thick sewing material
The adjustment of the stitch depth by one digit (= 1 point of the display unit) is
equal to a plunger height modification of 0.01 mm.
When turning the regulating button to the right to the stop a value between 003
and 006 appears on the display.
