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. Clut-
tered 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 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 imme-
diately. 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 influ-
ence of drugs, alcohol, or medication. A
moment of inattention 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.
■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 pro-
tection. 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 plat-
form. 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 preven-
tive safety measures reduce 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 condi-
tion that may affect the tools 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. Accesso-
ries that may be suitable for one tool, may be-
come hazardous when used on another tool.

Service
■Tool service must be performed only by
qualified repair personnel. Service or mainte-
nance performed by unqualified personnel could
result in a risk of injury.
■When servicing a tool, use only identical
replacement parts. Follow instructions in
Maintenance section of this manual. Use of
unauthorized parts or failure to follow Mainte-
nance Instructions may create a risk of electric
shock or injury.
Specific Safety Rules for Sanders
■Hold tool by insulated gripping surfaces
when performing an operation where the 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 opera-
tor.
■Never use this or any power sander for wet
sanding or liquid polishing. Failure to comply
canresultinelectricalshockcausingseriousinjury
or worse.
■Keep hands away from sanding area.
Additional Rules for Safe Operation
■Know your power tool. Read operator's manual
carefully. Learn its applications and limitations as
wellasthespecificpotentialhazardsrelatedtothis
tool.
■Always wear safety glasses. Everyday eye-
glasses 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.
■Don'tabusecord.Nevercarrytoolbycordoryank
it to disconnect from receptacle. Keep cord from
heat, oil and sharp edges.
■Make sure your extension cord is in good con-
dition. When using an extension cord, be sure to
use one heavy enough to carry the current your
product will draw. An undersized cord will cause a
drop in line voltage resulting in loss of power and
overheating. 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.
RULES FOR SAFE OPERATION
■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,aguardorotherpartthatisdamagedshouldbe
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 cen-
ter.
■Inspectforandremoveallnailsfromlumberbefore
sanding.
■Drugs, Alcohol, Medication. Do not operate tool
while under the influence of drugs, alcohol, or any
medication.
■Savetheseinstructions.Refertothemfrequently
and use them to instruct others who may use this
tool.If you loan someone this tool,loan them these
instructions also.

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.Doubleinsulatedtoolsdonotneedtobegrounded.
IMPORTANT
Servicing of a tool with double insulation requires extreme
careand knowledge ofthesystem and shouldbeperformed
onlybyaqualifiedservicetechnician.Forservicewesuggest
you return the tool to your nearest RYOBI AUTHORIZED
SERVICE CENTER for repair. When servicing use only
identical Ryobi replacement parts.
FEATURES
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.
OSCILLATING MOTION
The oscillating motion sands 3.0 mm arcs, providing fast
cutting action with excellent sanding results. As the name
implies,thistoolhasbeendesignedprimarilyfordetailedand

DO NOT FORCE. The weight of the unit supplies adequate
pressure, so let the sandpaper and sander do the work.
Applying additional pressure only slows the motor, rapidly
wears sandpaper and greatly reduces sander speed.
Excessivepressure willoverloadthemotorcausingpossible
damage from motor overheating and can result in inferior
work. Any finish or resin on wood may soften from the
frictional heat. Do not allow sanding on one spot too long as
sander'srapidactionmayremovetoomuchmaterial,making
the surface uneven.
SANDPAPER SELECTION
Selecting the correct size grit and type sandpaper 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 economical use in
power sanding.
Ingeneral,coarsegritwillremovethemostmaterialandfiner

WARNING:
Do not wear loose clothing or jewelry when operating
sander. They could get caught in moving parts causing
serious injury. Keep head away from sander and sanding
area. Hair could be drawn into sander causing serious
