material will not feed through machine?

With the presser foot down on the material you shouild not be able to pull the material through if the teeth are in the up position, if you can then you need more pressure on the foot, if you can't get the pressure on the foot take the long spring out of nthe presser bar and stretch it a bit then put it back, make sure the teeth are coming just above the needle plate when up.
