Troubleshooting:
Make sure to have good needles installed. If you're unsure, replace them with brand new ones.
Check the blades are cutting well. Use several strands of thread and put them under the top blade and turn the hand wheel until the blade comes down and the threads should be cut cleanly. If not, the blades will need sharpening.
Double check the treading and check the tensions.
