caution when moving the cart/apparatus combination to avoid injury
from tip-over.

apparatus has been damaged in any way, such as power-supply cord or plug is damaged,
liquid has been spilled or objects have fallen into the apparatus, the apparatus has been
exposed to rain or moisture, does not operate normally, or has been dropped.
