I need help with instructions of how to raise the blade on the saw. Turning the crank does not raise the blade. I need steps instruction on looking at the gear which makes the saw go up and down. I was trying to make a sled for the saw.. When I was raising the saw to cut through a piece of oak 3/4 plywood. It stopped going up.

Thank you for the response. I don't know how to get to the inside of the saw. I need instructions on where to begin to make the repair. Should I take the top off. Or should I take off the cranks in the front of the saw. I can't figure how to get inside of it. I can see using an endoscope that there is something crushed. It is orange and plastic. Just don't know how to get to it.

Thank you.

Thank you. I appreciate the time you took to reply to me. My problem is I don't know where to begin to solve my problem. The diagram gives me a good look at the saw top. Do I gain access to the spindle with the gears from the front of the saw or do I take the saw top off. I had called the number on the manual, but the person there said they didn't have a tech who could answer the question. They could provide me with parts, but had no idea how the saw was put together.
the saw is not made by Porter Cable. It just wears its label. I will call the number you've given me. Hopefully, I can get directions. Thanks again.
