Check Tension Check the tension of the bobbin by resting the loaded bobbin case in the palm of your hand. Pull the tail of thread and watch as the thread flows out of the bobbin case. A slight bounce should cause the bobbin case to slide down the thread. If the thread slides out of the case as you pick it up, it needs more tension. If it barely moves down the thread or doesn't move at all, it needs less tension (fig 34) Adjust Tension 1. Use a small screwdriver to turn the largest set screw on the bobbin case to adjust tension (fig. 35). 2. Make very small adjustments. 3. Be very careful not to remove the screw as it is very small and difficult to find if lost. 4. Remember, right (clockwise) tight, left (counter clockwise) loose. Place Bobbin into Machine 1. Insert the bobbin into the bobbin case. The bobbin can be placed into the bobbin case in either direction, but you should be consistent. 2. Holding the bobbin case pull the thread through the slot and under the tension spring. 3. Place the bobbin case in the machine. Always listen for the click as it engages into the machine (fig. 36). It is recommended to use a soft bristle brush to wipe out the bobbin case and the bobbin area. It is not recommended to use canned air as it will only blow the lint around. TIP: Lint has a tendency to build up in the bobbin case especially with cotton threads. Check the bobbin case each time you change a bobbin to keep it clean. Fig. 34 Fig. 35 Fig. 36 24
