I think UncleVic is on the right track. There was probably some residual "cutting" oil left over from the manufacture. Gunna have to get all that out, and be sure you get in all the nooks and cranneys where oil could be.
To be sure, it would be a wise thing to take appart as much as you can and then clean. Remove any handles, legs, etc. Maybe even take it to a spray car wash. use an engine degreaser ten soap and water then just water, dry. Lightly oil it with corn or canola oil and fire it up.
