GENERAL SAFETY RULES
SAVE THESE INSTRUCTIONS
WARNING:
Read and understand all instructions. Failure to fol­low all instructions listed below, may result in electric shock, fire and/or serious personal injury.
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 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 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 insu-
lation 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 an 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 inat-
tention while operating 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 or drawn into air vents.
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 at-
tached 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 en-
ables better control of the tool in unexpected situa­tions. Do not use on a ladder or unstable support.
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. Hold-
ing 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 mea-
sures 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 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.

GENERAL SAFETY RULES
SERVICE
Tool service must be performed only by quali­fied repair personnel. Service or maintenance per-
formed 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.
SPECIFIC SAFETY RULES
Hold tool by insulated gripping surfaces when performing an operation where the tool may contact wiring or its cord. Contact with a “live” wire will make exposed metal parts of the tool “live” and shock the operator.
ADDITIONAL SAFETY RULES
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 eye­glasses have only impact-resistant lenses; they are NOT safety glasses. Following this rule will re-
duce the risk of serious personal injury.
Protect your lungs. Wear a face or dust mask if the operation is dusty. Following this rule will re-
duce 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. Follow-
ing 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 elec-
tric shock or fire.
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.
Inspect for and remove all nails from lumber be­fore sanding. 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.

FEATURES
DOUBLE INSULATION
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 the 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 to avoid electrical shock.
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 authorized service center for repair. Always use original factory replacement parts when servicing.
ELECTRIC MOTOR
Your sander 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 your tool does not operate when plugged into an outlet, double-check the power supply.
SWITCH
Your sander has a conveniently located slide switch.
VARIABLE SPEED
The variable speed feature allows you to operate the sander at different speeds.
BACKING PAD
The backing pad on the sander provides the capability to use sanding discs with pressure sensitive adhesive backing material.
CONVERSION PAD
The conversion pad supplied with the sander converts the backing pad and allows you to use Velcro® type sanding discs.
RANDOM ORBIT
The random orbit motion provides overlapping sanding movements by combining orbital and turning motion. These overlapping sanding movements provide fast cutting action with excellent sanding results.
ERGONOMIC DESIGN
The design of the sander provides for easy handling. It is designed for comfort and ease of grasp when operating in different positions and at different angles.

SELECTING SANDING DISCS
Selecting the correct size grit and type of sanding disc is an extremely important step in achieving a high quality sanded finish. Aluminum oxide, silicon carbide, and other synthetic abrasives are best for power sanding. Natural abrasives, such as flint and garnet are too soft for power sanding.
In general, when sanding, coarse grit removes the most material and fine grit produces the best finish. The condition of the surface to be sanded determines which grit will do the best job. If the surface is rough, start with a coarse grit and sand until the surface is uniform. Then use medium grit to remove scratches left by the coarser grit. Finally, use finer grit for finishing the surface. Always continue sanding with each grit until the surface is uniform.

OPERATION
HELPFUL TIPS
Do not force the sander. The weight of the unit supplies adequate pressure; therefore, let the sand­ing disc and sander do the work. Applying additional pressure only slows the motor, rapidly wears the sanding disc, and greatly reduces the sander speed. Excessive pressure will overload the motor causing possible damage from motor overheating and can result in inferior work. Any finish or resin on the wood may soften from the frictional heat.
Do not sand on one spot too long. The sander’s
rapid action may remove too much material, making the surface uneven. Extended periods of sanding may tend to overheat the motor. If this occurs, turn off the sander and wait until the sanding disc comes to a complete stop. Then remove the sander from the workpiece. Remove your hand from the vent area, remove the sanding disc, then (with your hand removed from the vent area) turn on the sander and run it free, without a load, to cool the motor.
MAINTENANCE
WARNING:
When servicing use only identical Ryobi replacement parts. Use of any other parts may create a hazard or cause product damage.
GENERAL
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.
When electric tools are used on fiberglass boats, sports cars, wallboard, spackling compounds, or plaster, it has been found that they are subject to accelerated wear and possible premature failure, as the fiberglass chips and grindings are highly abrasive to bearings, brushes, commutators, etc. Consequently, it is not recommended that this tool be used for extended work on any fiberglass material, wallboard, spackling compounds, or plaster. If, however, you do work with any of these materials, 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.
