INTRODUCTION

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 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:

WEAR YOUR

SAFETY GLASSES

FORESIGHT IS BETTER

THAN NO SIGHT

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.

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 atmo- spheres, such as in the presence of flammable

liquids, gases, or dust. Power tools may 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 po- larized 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 refrigera-

tors. There is an increased risk of electric shock if your body is grounded.

■ Don’t expose power tools to rain or wet condi-

tions. 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 immedi-

ately. 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 operating power tools may result in serious personal injury.

3

■ Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, cloth-

ing, 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 turn-

ing 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 bal-

ance at all times. Proper footing and balance enables better control of the tool in unexpected situations. Do not use on a ladder or unstable support.

■ Use safety equipment. Always wear eye protec-

tion. 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 power source before making any adjustments, changing accessories,

or storing the tool. Such preventive safety measures reduce the risk of starting the tool accidentally.

■ Store idle tools out of the 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 dam-

aged, 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.

GENERAL SAFETY RULES

Service

■ Tool service must be performed only by quali-

fied repair personnel. Service or maintenance performed by unqualified personnel could result in a risk of injury.

■ When servicing a tool, use only identical replace- ment parts. Follow instructions in the Mainte-

nance section of this manual. Use of unauthorized parts or failure to follow Maintenance Instructions may create a risk of electric shock or injury.

SPECIFIC SAFETY RULES

Hold tool by insulated gripping surfaces when performing an operation where the cutting tool may contact

hidden wiring or its cord. Contact with a “live” wire will make exposed metal parts of the tool “live” and shock the operator.

Additional Rules For Safe Operation

■ Know your power tool. Read operator’s manual carefully. 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. Everyday eye- glasses have only impact-resistant lenses; they

are NOT safety glasses. Following this rule will reduce the risk of serious personal injury.

■ Protect your lungs. Wear a face or dust mask if

the operation is dusty. Following this rule will reduce the risk of serious personal injury.

■ Protect your hearing. Wear hearing protection

during extended periods of operation. Following this rule will reduce the risk of serious personal injury.

■ Inspect tool cords periodically and, if damaged, have repaired at your nearest Factory Service

Center or other Authorized Service Organization.

Constantly stay aware of cord location. Following this rule will reduce the risk of electric shock or fire.

■ 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 shock, fire, or serious injury.

■ Do not abuse cord. Never carry the tool by the cord or yank it to disconnect it from the receptacle. Keep cord away from heat, oil, and sharp

edges. Following this rule will reduce the risk of electric shock or fire.

■ Make sure your extension cord is in good condi- tion. 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.

■ Inspect for and remove all nails from lumber

before driving screws. Following this rule will reduce the risk of serious personal injury.

■ 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 personal 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.

MAINTENANCE

WARNING:

When servicing use only identical Ryobi replacement parts. Use of any other parts may create a hazard or cause product damage.

GENERAL

All parts represent an important part of the double insulation system and should be serviced only at an authorized service center.

Avoid using solvents when cleaning plastic parts. Most plastics are susceptible to damage from various types of commercial solvents and may be damaged by their use. Use clean cloths to remove dirt, carbon dust, etc.

WARNING

:

Do not at any time let brake fluids, gasoline, petroleum-based products, penetrating oils, etc. come in contact with plastic parts. They contain chemicals that can damage, weaken or destroy plastic.

It has been found that electric tools are subject to accelerated wear and possible premature failure when they are used on fiberglass boats, sports cars, wallboard, spackling compounds, or plaster. The chips and grindings from these materials are highly abrasive to electric tool parts, such as bearings, brushes, commutators, etc.

When using this tool on these type materials for extended periods of time, it is extremely important that the tool is cleaned frequently by blowing with an air jet.

WARNING:

Always wear safety goggles or safety glasses with side shields during power tool operation or when blowing dust. If operation is dusty, also wear a dust mask.

EXTENSION CORDS

The use of any extension cord will cause some loss of power. To keep the loss to a minimum and to prevent tool overheating, use an extension cord that is heavy enough to carry the current the tool 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. When working outdoors, use an extension cord that is suitable for outdoor use. The cord's jacket will be marked WA.

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.

Extension cords suitable for use with your screwdriver are available at your nearest authorized service center.

LUBRICATION

All of the bearings in this tool are lubricated with a sufficient amount of high-grade lubricant for the life of the unit under normal operating conditions. Therefore, no further lubrication is required.
