●
Unthread the machine.
●
Place the workpiece under the presser foot.
●
Let the machine sew at maximum speed and
check whether the needle always penetrates
the workpiece in the same place.
(The workpiece should not move).
Correcting the setting
●
Change the value for parameter
834
within the
permissible values until the needle always
penetrates the workpiece in the same place,
see
Section 1.1.
The zero position of the feed regulator
is always recognisable in a range of 3
values. When making the adjustment,
select the middle value.
Example:
When selecting the values „1“, „0“ and „+1“, the
workpiece does not move.
=> Value:
0
●
If the zero point of the feed regulator cannot be
set by selecting one of the permissible values,
the mechanical setting must be checked or
corrected, see
Chapter 13.05.11 Zero position
of the bottom feed dog
…in the Instruction
Manual.
The permissible values
for parameter
834
are
„1“, „0“ and „+1“.
