INTRODUCTION
DOUBLE INSULATION
Your Ryobi power tool is double insulated. 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 internal metal motor
components with protecting insulation. Double insulated tools
do not need to be grounded.
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:
The operation of any laminate trimmer 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. Always wear eye protection which is marked to comply with ANSI Z87.1.
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.
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.

GENERAL SAFETY RULES
WARNING:
Read and understand all instructions. Failure to
follow all instructions listed below, may result in electric shock, fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS
Work Area
■ Keep your work area clean and well lit. Cluttered
benches and dark areas invite accidents.
■ Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks which
may ignite the dust or fumes.
■ Keep bystanders, children, and visitors away while
operating a power tool. Distractions can cause you to
lose control.
Electrical Safety
■ Double insulated tools are equipped with a polarized
plug (one blade is wider than the other). This plug
will fit in a polarized outlet only one way. If the plug
does not fit fully in the outlet, reverse the plug. If it
still does not fit, contact a qualified electrician to install a polarized outlet. Do not change the plug in any
way. Double insulation eliminates the need for the
three wire grounded power cord and grounded power
supply system.
■ Avoid body contact with grounded surfaces such as
pipes, radiators, ranges and refrigerators. There is a n
increased risk of electric shock if your body is grounded.
■ Don't expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of electric shock.
■ Do not abuse the cord. Never use the cord to carry
the tools or pull the plug from an outlet. Keep cord
away from heat, oil, sharp edges or moving parts.
Replace damaged cords immediately . Damaged cords
increase the risk of electric shock.
■ When operating a power tool outside, use an outdoor
extension cord marked “W-A” or “W”. These cords are
rated for outdoor use and reduce the risk of electric shock.
Personal Safety
■ Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use
tool while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operat-
ing power tools may result in serious personal injury .
■ Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, clothing, and
gloves away from moving parts. Loose clothes, jewelry ,
or long hair can be caught in moving parts.
■ Avoid accidental starting. Be sure switch is off before
plugging in. Carrying tools with your finger on the switch
or plugging in tools that have the switch on invites accidents.
■ Remove adjusting keys or wrenches before turning
the tool on. A wrench or a key that is left attached to a
rotating part of the tool may result in personal injury.
■ Do not overreach. Keep proper footing and balance
at all times. Proper footing and balance enables better
control of the tool in unexpected situations.
■ Use safety equipment. Always wear eye protection.
Dust mask, nonskid safety shoes, hard hat, or hearing
protection must be used for appropriate conditions.
Tool Use and Care
■ Use clamps or other practical way to secure and support the workpiece to a stable platform. Holding the
work by hand or against your body is unstable and may
lead to loss of control.
■ Do not force tool. Use the correct tool for your application. The correct tool will do the job better and safer at
the rate for which it is designed.
■ Do not use tool if switch does not turn it on or off.
Any tool that cannot be controlled with the switch is dangerous and must be repaired.
■ Disconnect the plug from the power source before
making any adjustments, changing accessories, or
storing the tool. Such preventive safety measures re-
duce risk of starting the tool accidentally.
■ Store idle tools out of reach of children and other
untrained persons. Tools are dangerous in the hands of
untrained users.
■ Maintain tools with care. Keep cutting tools sharp and
clean. Properly maintained tools with sharp cutting edges
are less likely to bind and are easier to control.
■ Check for misalignment or binding of moving parts,
breakage of parts, and any other condition that may
affect the tool's operation. If damaged, have the tool
serviced before using. Many accidents are caused by
poorly maintained tools.
■ Use only accessories that are recommended by the
manufacturer for your model. Accessories that may
be suitable for one tool, may become hazardous when
used on another tool.
Service
■ Tool service must be performed only by qualified repair personnel. Service or maintenance performed by
unqualified personnel could result in a risk of injury.
■ When servicing a tool, use only identical replacement
parts. Follow instructions in the Maintenance section
of this manual. Use of unauthorized parts or failure to
follow Maintenance Instructions may create a risk of electric shock or injury.

GENERAL SAFETY RULES
■ Keep the tool and its handle dry , clean, and free from
oil and grease. Always use a clean cloth when clean
SPECIFIC SAFETY RULES
Additional Rules for Safe Operation
■ Know your power tool. Read operator's manual care-
fully. Learn its applications and limitations as well as the
specific potential hazards related to this tool. Following
this rule will reduce the risk of electric shock, fire, or
serious injury.
■ Always wear safety glasses with side shields. Every-
day eyeglasses have only impact resistant lenses; they
are NOT safety glasses.
■ Protect your lungs. Wear a face or dust mask if the
operation is dusty.
■ Protect your hearing. Wear hearing protection during
extended periods of operation.
■ Hold tool by insulated gripping surfaces when performing an operation where the cutting tool may
contact hidden wiring or its own cord. Contact with a
"live" wire will make exposed metal parts of the tool "live"
and shock the operator.
■ Inspect tool cords periodically and if damaged, have
repaired at your nearest authorized service center. Stay
constantly aware of cord location.
■ Check damaged parts. Before further use of the tool, a
guard or other part that is damaged should be carefully
checked to determine that it will operate properly and
perform its intended function. Check for alignment of
moving parts, binding of moving parts, breakage of parts,
mounting, and any other conditions that may affect its
operation. A guard or other part that is damaged should
be properly repaired or replaced by an authorized service
center. Following this rule will reduce the risk of electric
shock, fire, or serious injury.
■ Do not abuse cord. Never carry tool by cord or yank
it to disconnect from receptacle. Keep cord from
heat, oil and sharp edges. Following this rule will reduce
the risk of electric shock or fire.
ng. Never use brake fluids, gasoline, petroleum-based
products, or any strong solvents to clean your
■ Make sure your extension cord is in good condition.
When using an extension cord, be sure to use one heavy
enough to carry the current your product will draw. A wire
gage size (A.W.G.) of at least 16 is recommended for an
extension cord 100 feet or less in length. A cord exceeding 100 feet is not recommended. If in doubt, use the next
heavier gage. The smaller the gage number, the heavier
the cord. An undersized cord will cause a drop in line
voltage resulting in loss of power and overheating.
■ Drugs, Alcohol, Medication. Do not operate tool while
under the influence of drugs, alcohol, or any medication.
Following this rule will reduce the risk of electric shock,
fire, or serious injury.
■ Save these instructions. Refer to them frequently and
use them to instruct others who may use this tool. If you
loan someone this tool, loan them these instructions also.

WARNING:
Some dust created by power sanding, sawing, grinding,
drilling, and other construction activities contains
chemicals known to cause cancer, birth defects or
other reproductive harm. Some examples of these
chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other
masonry products, and
• arsenic and chromium from chemically-treated
lumber.
Your risk from these exposures varies, depending on
how often you do this type of work. To reduce your
exposure to these chemicals: work in a well ventilated
area, and work with approved safety equipment, such
as those dust masks that are specially designed to filter
out microscopic particles.
