DOUBLE INSULATION
Double insulation is a concept in safety in electric power
tools, which eliminates the need for the usual three-wire
grounded power cord. 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 authorized service center for repair. When
servicing, use only identical Ryobi replacement parts.
WARNING:
The double insulated system is intended to protect
the user from shock resulting from a break in the
tool's internal wiring. Observe all normal safety pre-
cautions related to avoiding electrical shock.
ELECTRICAL CONNECTION
The router has a precision built electric motor. It should
be connected to a power supply that is 120 volts, 60 Hz,
AC only (normal household current). Do not operate this
tool on direct current (DC). A substantial voltage drop will
cause a loss of power and the motor will overheat. If your
tool does not operate when plugged into an outlet,
double-check the power supply.
EXTENSION CORDS
When using a power tool at a considerable distance from
a power source, be sure to use an extension cord that
has the capacity to handle the current the tool will draw.
An undersized cord will cause a drop in line voltage,
resulting in overheating and loss of power. Use the chart
to determine the minimum wire size required in an
extension cord. Only round jacketed cords listed by
Underwriter’s Laboratories (UL) should be used.
When working outdoors with a tool, use an extension
cord that is designed for outside use. This type of cord is
designated with “WA” on the cord’s jacket.
Before using any extension cord, inspect it for loose or
exposed wires and cut or worn insulation.

WARNING:
Keep the extension cord clear of the working
area.Position the cord so that it will not get caught on
lumber, tools or other obstructions while you are work-
ing with a power tool. Failure to do so can result in
serious personal injury.
WARNING:
Check extension cords before each use. If damaged
replace them immediately. Never use tool with a dam-
aged cord with this tool. Touching the damaged area
could cause serious injury due to electrical shock.
