Turning The Flywheel Is Very Stiff When Lifting The Needle. There Is A High- Pi

A squeaking sound inside the machine, very common and could possibly be from a need for a service. Basically you are going to do a mini service.

1. Do not put oil on the motor or near any of the belts. This will cause slipping and you will have no power. Also old motors can spark so keep the oil away.

2. You are allowed to unscrew the top plate and the bottom plate. You can take off the plate that the presser foot rests on and look in the feed dogs that come up through that plate to see if there is any lint build up down there. Visually inspect for thread build up. The best way to handle this is by blowing out the whole mechanism with an air compressor or a can of air. This will delint the machine and expose any bound threads.

3. Change the needle and check to make sure needle is in correctly. Take out the bobbin case and look for lint inside the bobbin case. after this is out, go get machine oil from Home Depot or Lowe's. I prefer Tri-flow. Avoid WD-40 and penetrating oils as these will remove the good grease instead of re-lubricating the machine. You will run the machine spraying all visible moving parts and eventually you will hear a reduction in noise. Stay away from motor again as you do this. Now the open top is sprayed, the needle holding bar and surrounding mechanism is sprayed. The hook and the mechanism that holds the bobbin case should be sprayed. Also, spray the mechanical parts beneath the machine.

4. Use a can of compressed air and blow out excess oil. Make sure tension springs and anywhere thread runs is free of lint. Blow hard on the upper tension spring.

5. Because you have not touched any tension screws you should be able to reassemble and start sewing where you left off.

6. Don't be afraid to take the plates off the machine and clean and oil, you wont hurt your machine and if you get into a bind the sewing store can usually help.

7. Re-assemble
