DOUBLE INSULATION

Your Ryobi power tool is double insulated. This means  you
are separated from the tool's electrical system by two complete
sets of electrical insulation. This extra layer of insulation is
intended to protect the user from electrical shock due to a
break in the wiring insulation. All exposed metal parts are
isolated from the internal metal motor components with
protecting insulation. Double insulated tools do not need to
be grounded.

IMPORTANT

Servicing of a tool with double insulation requires extreme
care and knowledge of the system and should be performed
only by a qualified service technician. For service we suggest
you return the tool to your nearest RYOBI AUTHORIZED
SERVICE CENTER
  for repair. When servicing use only
identical Ryobi replacement parts.

prevention measures.
