hercules structor parts?

i just received my hercules structor figure but it did not come with instructions. Said instructions probably would have told me what the two little grey pieces of plastic that came with structor are for.
i assume they're some sort of remedy parts like the exgraver shovel arm that came with heavylabor but i dunno
can anyone clue me in?
