malfunction or breakdown, grounding provides a
path of least resistance for electrical current to
reduce the risk of electrical shock. This machine
is equipped with a cord having an
equipment–grounding conductor and grounding
plug. The plug must be plugged into an
appropriate outlet that is properly installed in
accordance with all local codes and ordinances.
Do not remove ground pin; if missing, replace
plug before use.
