Adjusting Bobbin Tension
1. To adjust the tension, access the adjustment screw (the larger of the two) on the tension spring from
the recessed corner of the gauge.
2. Using a small at-blade screwdriver, turn the adjustment screw in small increments between testing.
Small rotations can make large adjustments to the tension.
o Clockwise: This increases the tension on the bobbin thread.
o Counter Clockwise: This decreases the tension on the bobbin thread.
