5.1 Fitting the thread guide
Abb. 14: Installing the thread guide
1. Attach the thread guide (2).
2. Tighten the screws (1).
3. The thread guide (2) must lie flush against the machine - bend the
thread guide (2) by hand if necessary.
Bend if required
Abb. 15: Position of thread guide
1. Check the position of the thread guide on the sewing machine arm.
2. If the position is correct, continue fitting the BTSR sensor.

3. If the position is NOT correct, the thread guide will have to be bent
slightly.
Abb. 16: Bending the thread guide
4. Bend the thread guide using a pair of pliers in the upper left area (3).
5. Bend the thread guide back again afterwards in the right-hand area (4)
if necessary.
5.2 Installing the BTSR sensor

5.4 Installing thread lever protection
Abb. 20: Installing thread lever protection
1. Attach the thread lever protection (6) so that it is located as far down
from the sensor and as much to the right as possible from this and
thereby does not collide with the thread lever (4) .
2. Check the thread lever protection (6) does not collide with the thread
lever (4).
3. Tighten the screws (5) on the thread lever protection (6).
4. Loosen the screw (3) on the head cover (2).
5. Position the head cover (2) so it is flush with the machine again.
6. Insert the screw (1) on the head cover.
7. Tighten screws (1) and (3).

5.5 Machine following upgrade
To be able to use the sensor, it is important to pay attention to the following
points:
• the thread guide (1) must lie flush against the sewing machine arm
5.1 Fitting the thread guide, p. 12.
• the edge (2) of the thread clamp must be parallel to the edge (2) of
the BTSR sensor, 5.3 Fitting the thread clamp, p. 14
