Lee,
I do believe these are the correct labels for the two red handles. I think that they were stamped on the label in two lines. If they were, I don't know which character would start the second line. Possibly after 出. This would break it down to the first four characters on the top line meaning Emergency Leg Extension, followed by the last three for Handle Left/Right.
応急脚出把手左 Emergency Leg Extension Handle, Left
応急脚出把手右 Emergency Leg Extension Handle, Right
