Keep the unit away from children. If operated by a child, an adult shall watch the operation.
Set the switch to OFF after usage and remove the batteries or pull off the plug.
Don’t mix old batteries with new ones.
Don’t dismantle or rebuild the unit.
Don’t switch on when fabric has not been put on the unit even though top and bottom threads
are ready.
Troubleshooting
1. The sewing machine does not run when the power switch is pressed.
•Batteries are inserted incorrectly. Insert the batteries again using the diagram provided
inside the battery compartment.
•Batteries are exhausted. Replace with new batteries.
•Make sure the Adapter (6V,1.2A) and foot controller are connected in the right position.

2. The sewing machine runs, but does not form stitches.
•Incorrectly threaded machine. Re-thread the machine.
•Needle is incorrectly threaded. Make sure thread is threaded from left to right.
•Needle is not properly inserted.
•Batteries are installed incorrectly. Check the diagram in the battery compartment and
re-install.
•Caution: To remove fabric after sewing, first turn the handwheel to raise the needle to the
highest position. Lift the presser foot and remove the fabric. This will avoid bending the
needle.
3. The machine runs slowly.
•Used batteries and new batteries are used together. Replace with new batteries.
•Use only AA(#3, 1.5V) batteries.
4. The sewing machine stops sewing.
•Very heavy fabric or too many layers of fabric will force the sewing machine to stop.
•Thread is tangled in the lower bobbin. Stop the machine. Cut the tangled threads to clear it
from the machine. Re-thread both the bobbin and the needle.
•Poor quality stitching: Refer to “Adjusting Thread Tension” on page 9.
•When new batteries are installed, the sewing machine should work for approximately 2
hours under normal sewing conditions. Remember that heavy fabric requires more power, so
it will reduce the running time of the batteries.
