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

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.

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

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.
