Adjusting The Stitch Length - DURKOPP ADLER 838 Instruction Manual

6.12 Adjusting the stitch length

20
The special sewing machine 838 is equipped with two setting wheels.
This allows you to sew with two different stitch lengths which can be
activated during the sewing process by pressing a button.
The stitch lengths are set using the two setting wheels (1) and (4)
found on the machine arm.
–
Set the larger stitch length with the upper setting wheel (1). Turn
the setting wheel until the desired number (the stitch length in mm)
is marked (3).
–
Set the smaller stitch length with the lower setting wheel (4). Turn
the setting wheel until the desired number (the stitch length in mm)
is marked (3).
–
Stitch lengths are equal for both forward and reverse sewing.
CAUTION Danger of breakage!
Make sure that the stitch length set with the lower setting wheel (4) is
not larger as the stitch length set by the upper setting wheel (1).
Note: In order to facilitate the process of adjusting the stitch lengths,
the button (4) should be used to fix the stitch lengths so that they do
not shift.
