BSr Description

By activating the BSr function the sewing
computer sews either continuously at a
reduced motor speed (mode 1, standard),
or as soon as the fabric is moved (mode 2).
as long as the BSr presser foot is illumi-
nated red, adjustments like threading and
changing the needle, for example must not
be carried out, as the needle will engage
while fabric is moved unintentionally!
Without fabric feed the BSr mode is
turned off after approx. 7 seconds and the
red light goes off.
please refer to the Safety Instructions!
When exceeding a certain speed, adhering to
regular stitch length cannot be guaranteed.
Make sure that the lens on the bottom of
the BSR foot is not dirty (fingerprints, etc.).
Clean lens periodically with soft, slightly
damp cloth.

BSr (BernIna Stitch regulator) function
The BSR presser foot reacts to the movement of the fabric under the foot and controls the
speed of the sewing computer up to the maximum speed possible. The following applies:
the faster the fabric is moved the higher the speed of the sewing computer.
If the fabric is moved too fast an acoustic signal (beep) is heard, and the red light of the
Start-/Stop Button flashes. The beeper can be turned on or off in the Setup Program or
directly on the «BSR» screen.

With Straight Stitch no. 1
This function using a special presser foot allows for Free
Motion quilting (sewing) using the straight stitch and a
pre-selected stitch length (up to 4mm).
A regulated set stitch length is maintained within a certain
speed, independent of the movement of the fabric.
With Zigzag Stitch no. 2
The zigzag stitch can be used for thread painting or fabric
embellishment.
The set stitch length will not be maintained when sewing
with the zigzag stitch, but the BSR function simplifies
the application.
BSr function can be sewn in 2 separate
modes of operation
► BSR mode 1 is the active standard
► the sewing computer runs continuously at a reduced
motor speed, as soon as the foot control or the Start/
Stop Button is pressed
► moving the fabric under the foot will engage the sewing
computer to accelerate
► through the continuous needle movement securing in
the same position is possible without pressing an
additional button
► touch the button «BSR2» to engage BSR mode 2
► the sewing computer will only engage if the foot control
or the Start/Stop Button is pressed and the fabric is
moved simultaneously
► the movement of the fabric determines the sewing
speed
► for securing, the «Securing Function» button must be
pressed
► touch the button «BSR1» to engage BSR mode 1
For an even sewing start (one single stitch)
the foot control must be pressed and the fabric
moved simultaneously.
This also applies for sewing points and
straight stitching within a round form.
If the BSR function is deactivated and later
re-activated without the sewing computer
being switched off in between, the last
selected BSR mode is active.
