  • Page 22: Binding Tips

    Feed roller pressure may be reduced to make turning the machine easier. When operating with less pressure, use care not to force the machine and deflect or break the needle. Feed roller height is changed by loosening the set screw in the lift dog (part #178 Model 126, #778 Model 155). BASE BINDING If base starts to curl when binding, it is usually caused by tension on the binding tape.

  • Page 23: Folder Adjustment

    FOLDER ADJUSTMENTS For uneven folds where the bottom stitch misses the tape there are 2 possible solutions. 1. Place a straight edge in the front of the folder. Adjust the folder guide (part #126-1521) so that it just touches the straight edge and is at a slight angle away from the edge at the front. Trial and error maybe necessary with slightly more movement to the left (See Figure 1).
