use singer grease (lubricant) little dabs on the gears - not familiar with the machine but the top may come off and you'll be able to see the gears - just turn the wheel and put little dabs of grease around the gear teeth...
there may be gears on the bottom also - whereas you just do the same thing - little dabs of grease on the teeth..
then sewing machine oil on any thing else that has two metals rubbing together
usually walmart, joanns, hancocks, dime stores, have singer lubricant and sewing machine oil. the lubricant is generally in a little blue/white tube
