Check Spring Adjustment

With the machine threaded and fabric under the presser foot turn the hand wheel towards you to
produce 3 or 4 stitches. STOP
Now continue to turn the hand wheel towards you until the thread take up lever Fig 1 is at its highest
point. STOP
The thread should have pulled the check spring down from its stop or rest point.
Continue turning the hand wheel slowly towards you until the eye of the needle has just entered the
fabric. STOP
The check spring should now be resting with no more tension on it.©
If it rests too early (before the eye has entered the fabric) slacken the tension unit screw Fig 2 and turn
the tension unit to the left about 1/8
If it rests too late (after the eye has entered the fabric) slacken the tension unit screw
Fig 2 and turn the tension unit to the right about 1/8
