RULES FOR SAFE OPERATION
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 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 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 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 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 condition 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 become hazardous when used on another tool.

RULES FOR SAFE OPERATION
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 Maintenance 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 operator.
■ Never use this or any power sander for wet
sanding or liquid polishing. Failure to comply
can result in electrical shock causing serious injury
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
well as the specific potential hazards related to this
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't abuse cord. Never carry tool by cord or yank
it to disconnect from receptacle. Keep cord from
heat, oil and sharp edges.
■ 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. 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.
■ 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.
■ Inspect for and remove all nails from lumber before
sanding.
■ Drugs, Alcohol, Medication. Do not operate tool
while under the influence of drugs, alcohol, or any
medication.
■ 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
Your sander is suitable for sanding with coarse, medium, and
fine grit sandpaper. It will produce a fine scratch free finish
when used to sand with the grain on wood surfaces. By
purchasing optional accessories, it can also be used as a
polisher or scraper.
Before attempting to use your sander, familiarize yourself
with all operating features and safety requirements.
See Figure 1.
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.
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.
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.
OSCILLATING MOTION
The oscillating motion sands 3.0 mm arcs, providing fast
cutting action with excellent sanding results. As the name
implies, this tool has been designed primarily for detailed and
intricate sanding. For example, refinishing furniture, chairs,
etc., enabling you to sand in places that are hard to get to.
SWITCH
This tool is equipped with a simple switch control. To turn your
sander ON, depress the switch button as shown in Figure 1.
Depress the switch button in the opposite direction to turn
your sander OFF.
ELECTRICAL CONNECTION
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 willl overheat. If your tool does not operate when plugged into an outlet, double-check the power supply.

OPERATION
PREPARING FOR OPERATION
CAUTION:
Be careful not to let your hand cover the air vents.
TO OPERATE
When applicable, clamp or otherwise secure the work to
prevent it from moving under your sander.
WARNING:
Unsecured work could be thrown towards the operator
causing injury.
SANDING
See Figures 3 and 4.
Hold sander in front and away from you, keeping it clear of the
workpiece. Start sander and let the motor build to its maximum
speed, then gradually lower on the work with a slight forward
movement. Move it slowly over workpiece using forward and
backward or side to side strokes. Upon completion of sanding
operation, always remove sander from workpiece before
turning it off.
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.
Excessive pressure will overload the motor causing possible
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's rapid action may remove too much material, making
the surface uneven.
Fig. 3
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.
In general, coarse grit will remove the most material and finer
grit will produce the best finish in all sanding operations. The
condition of the surface to be sanded will determine which grit
will do the job. If the surface is rough, start with a coarse grit
and sand until the surface is uniform. Medium grit may then
be used to remove scratches left by the coarser grit and finer
grit used for finishing of the surface. Always continue sanding
with each grit until surface is uniform.
Fig. 4
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
injury.

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 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, petroleumbased 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. During any use on 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.
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.
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.
CAUTION:
Keep extension cords away from any sanding area and
position the cord so that it will not get caught on lumber,
tools, etc., during sanding operation.
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.
