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 precautions
related to avoiding electrical shock.
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 technician. For service, we suggest
you return the tool to your nearest authorized
service center for repair. When servicing, use
original factory replacement parts .
ELECTRICAL
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 under-
sized 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 should be used.
When working with a tool outdoors, use an extension cord
that is designed for outside use. This is indicated by the letters
"WA" on the cord's jacket.
Before using any extension cord, inspect it for loose or
exposed wires and cut or worn insulation.

ELECTRICAL CONNECTION
This tool 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 our tool does not
operate when plugged into an outlet, double-check the
power supply.
WARNING:
Keep the extension cord clear of the working area.
Position the cord so that it will not become entangled in
the rotating foam pad or caught on lumber, tools or
other obstructions while you are working with a power
tool. Failure to do so can result in serious personal
injury.
WARNING:
Check extension cords before each use. If damaged,
replace immediately. Never use tool with a damaged
cord since touching the damaged area could cause
electrical shock resulting in serious injury.
