RULES FOR SAFE OPERATION

Look for this symbol to point out important safety precautions.
It means attention!!! Your safety is involved.

The operation of any plate joiner can result in foreign objects being thrown into your
eyes, which can result in severe eye damage. Before beginning power 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.

WARNING:

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 owner's manual
and review frequently for continuing safe operation, and
instructing others who may use this tool.

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 ORGANIZATION 

for repair.

When servicing use only identical Ryobi replacement
parts.

THE PURPOSE OF SAFETY SYMBOLS IS TO ATTRACT YOUR ATTENTION TO POSSIBLE DANGERS. THE
SAFETY SYMBOLS, AND THE EXPLANATIONS WITH THEM, DESERVE YOUR CAREFUL ATTENTION AND
UNDERSTANDING. THE SAFETY WARNINGS DO NOT BY THEMSELVES ELIMINATE ANY DANGER. THE
INSTRUCTIONS OR  WARNINGS THEY GIVE ARE NOT SUBSTITUTES FOR PROPER ACCIDENT PREVENTION
MEASURES.
