Setting Bobbin Fill Level
The APQS Bobbin Winder can be set for either “L” or “M” size bobbins and will need to be set up prior to the
first bobbin fill. To help the bobbins wind more evenly, add one thick and one thin washer to the pin where
the bobbin is mounted before adding the empty bobbin. The winder uses an optical sensor to “see” how full
the bobbin is. This sensor is adjusted by loosening the two mounting screws on the sensor housing with a
Phillips screwdriver.
A “preliminary setting” would be similar to what is shown below, depending on bobbin size. The line is a
visual representation of where the sensor is “seeing” the thread level on each bobbin size. For the “L” size,
the mounting screws are positioned just to the left of center in the opening for the screw. The “M” size is
just to the right, as shown below.
