Requirement
When the feed regulator is set at "0", at maximum speed (4500 spm) the needle should
always penetrate at the same point.
●
Unthread the machine.
●
Switch the machine on.
●
Place the workpiece under the presser foot.
●
Let the machine sew at maximum speed and check the
requirement.
(The workpiece should not move).
●
Change the value for parameter

within the permissible values in accordance with the
requirement.
The permissible values for parameter 834 are "-1", "0" or "1".
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.
The zero point of the feed regulator is always recognisable in a range of 3 values.
When making the adjustment, the average value must be selected.
