ram won't reverse

The ram sticks in down position. Motor continues to (rattle?) I did not have any material in the compactor although there are statements in the instructions to fill it half full. Will the ram not reverse if it goes to full down when empty? If it should, any suggestions as to what the problem is?

Thanks

Seems the response is for correcy “yoga” postion, not compactor
problem resolution.
