RULES FOR SAFE OPERATION  
Service  
Inspect tool cords periodically and if damaged,  
have repaired at your nearest authorized service  
center. Stay constantly aware of cord location.  
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 re-  
placement parts. Follow instructions in Mainte-  
nance section of this manual. Use of unautho-  
rized parts or failure to follow Maintenance Instruc-  
tions may create a risk of electric shock or injury.  
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 oper-  
ate properly and perform its intended function.  
Check for alignment of moving parts, binding of  
movingparts,breakageofparts,mounting,andany  
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.  
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  
sandingorliquidpolishing. Failuretocomplycan  
result in electrical shock causing serious injury or  
worse.  
Inspectforandremoveallnailsfromlumberbefore  
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.  
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.  
Alwayswearsafetyglasses.Everydayeyeglasses  
have only impact-resistant lenses; they are NOT  
safety glasses.  
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:  
Protectyourlungs. Wearafaceordustmaskifthe  
• lead from lead-based paints,  
operation is dusty.  
• crystalline silica from bricks and cement and other  
masonry products, and  
Protect your hearing. Wear hearing protection  
during extended periods of operation.  
• arsenic and chromium from chemically-treated  
lumber.  
Don't abuse cord. Never carry tool by cord or yank  
it to disconnect from receptacle. Keep cord from  
heat, oil and sharp edges.  
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.  
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. Thesmallerthegagenumber, theheavierthe  
cord.

FEATURES  
Your sanderissuitableforsandingwithcoarse, 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.  
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.  
Beforeattemptingtouseyoursander,familiarizeyourself  
with all operating features and safety requirements.  
See Figure 1.  
OSCILLATING MOTION  
DOUBLE INSULATION  
In electric power tools, double insulation is a concept in  
safety 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.  
The oscillating motion sands 3.0 mm arcs, providing fast  
cutting action with excellent sanding results. As the name  
implies, thistoolhasbeendesignedprimarilyfordetailedand  
intricate sanding. For example, refinishing furniture, chairs,  
etc., enabling you to sand in places that are hard to get to.  
IMPORTANT  
SWITCH  
Servicing of a tool with double insulation requires extreme  
care and knowledge of the system and should be performed  
onlybyaqualifiedservicetechnician.Forservicewesuggest  
you return the tool to your nearest RYOBI AUTHORIZED  
SERVICE CENTER for repair. When servicing use only  
identical Ryobi replacement parts.

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.  
Fig. 3  
Holdsanderinfrontandawayfromyou, keepingitclearofthe  
workpiece.Startsanderandletthemotorbuildtoitsmaximum  
speed, then gradually lower on the work with a slight forward  
movement. Move it slowly over workpiece using forward and  
backwardorsidetosidestrokes.Uponcompletionofsanding  
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.  
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.  
Fig. 4  
In general, coarse grit will remove the most material and finer  
grit will produce the best finish in all sanding operations. The  
conditionofthesurfacetobesandedwilldeterminewhichgrit  
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  
gritusedforfinishingofthesurface. Alwayscontinuesanding  
with each grit until surface is uniform.  
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  
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,itisnotrecommendedthatthistoolbeusedfor  
extendedworkonanyfiberglassmaterial,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:  
When servicing use only identical Ryobi replacement  
parts. Use of any other parts may create a hazard or  
cause product damage.  
GENERAL  
Avoidusingsolventswhencleaningplasticparts.Mostplastics  
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:  
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.  
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.  
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  
normaloperatingconditions. Therefore, nofurtherlubrication  
is required.  
EXTENSION CORDS  
The use of any extension cord will cause some loss of power.  
Tokeepthelosstoaminimumandtopreventtooloverheating,  
use an extension cord that is heavy enough to carry the  
current the tool will draw.  
WARNING:  
Check extension cords before each use. If damaged  
replaceimmediately. Neverusetoolwithadamagedcord  
since touching the damaged area could cause electrical  
shock resulting in serious injury.  
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.
