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 electri-
cal shock due to a break in the wiring insulation. All ex-
posed 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 ex-
treme 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.
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.
WARNING:
Do not attempt to operate this tool until you have
read thoroughly and understand completely all
instructions, safety rules, etc. contained in this
manual. Failure to comply can result in accidents
involving fire, electric shock, or serious personal
injury. Save operator's manual and review
frequently for continuing safe operation, and
instructing others who may use this tool.
Look for this symbol to point out important safety
precautions. It means attention!!! Your safety is involved.
WARNING:
The operation of any power tool can result in foreign objects being thrown into your
eyes, which can result in severe eye damage. Before beginning tool operation, always
wear safety goggles or safety glasses with side shields and a full face shield when
needed. We recommend Wide Vision Safety Mask for use over eyeglasses or standard
safety glasses with side shields. Always wear eye protection which is marked to comply
with ANSI Z87.1.
