tion or breakdown, an electrical ground provides a path
of least resistance for the electric current. This path of
least resistance is intended to reduce the risk of electric
shock.
This tool’s electric cord has a grounding conductor and
a grounding plug as shown. Do not modify the plug.
Connect the plug to a corresponding GFCI-protected
receptacle that is properly installed and grounded in
accordance with all national and local codes and
ordinances.
Do not use an adapter.
Electric shock hazard:
