RULES FOR SAFE OPERATION (Continued)
19. REMOVE ADJUSTING KEYS AND
WRENCHES. Form habit of checking to see
that keys and adjusting wrenches are removed
from tool before turning it on.
20. AVOIDACCIDENTALSTARTING. Don'tcarry
plugged-in tools with finger on switch. Be sure
switch is off when plugging in.
21. MAKESUREYOUREXTENSIONCORDISIN
GOOD CONDITION. When using an extension
cord, be sure to use one heavy enough to carry
the current your product will draw. An under-
sized 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 recom-
mended 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,theheavier
the cord.

to clean your tool.
• crystalline silica from bricks and cement and
other masonry products, and
• arsenic and chromium from chemically-treated
lumber.
Your risk from these exposures varies, depend-
ing on how often you do this type of work. To re-
duce 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.
29. STAY ALERT. Watch what you are doing and
use common sense. Do not operate tool when
you are tired. Do not rush.
30. CHECK DAMAGED PARTS. Before further
use of the tool, a guard or other part that is

OPERATION
WARNING: ALWAYS WEAR SAFETY GOGGLES OR SAFETY GLASSES WITH SIDE SHIELDS WHEN
OPERATING YOUR SANDER. FAILURE TO DO SO COULD RESULT IN FOREIGN OBJECTS BEING
THROWN INTO YOUR EYES, RESULTING IN POSSIBLE SERIOUS INJURY. IF THE SANDING OPERATION
IS DUSTY, ALSO WEAR A FACE OR DUST MASK.
APPLICATIONS
(Use only for the purposes listed below)
1. Sanding on wood surfaces.
2. Removing rust from and sanding steel surfaces.
3. Sanding plastics.
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
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.

Note: DO NOT use sander without sandpaper. Doing so will
damage the cushion.

WARNING: UNSECURED WORK COULD BE
THROWN TOWARDS THE OPERATOR CAUSING
INJURY.
Hold your sander in front and away from you, keeping it clear
of the workpiece. Start your sander by pressing the switch
button to "ON" position and letting the motor build to its
maximum speed. Gradually lower your sander on the work
with a slight forward movement. See Figure 4. Move it slowly
Fig. 5
using forward and backward strokes.
Flush sanding can be performed with your sander. See
Figure 5. The front edge of your sander allows flush sanding
in corners. Always remove sander from workpiece before
turning your sander 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
the sander's rapid action may remove too much material,
making the surface uneven.
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.

OPERATION
ORBITAL MOTION
Orbital motion is ideal for fast cutting action when removing
old finishes, smoothing rough wood, cutting stock down to
required dimensions, or for finishing surfaces to be painted.
As shown in figure 6, the sandpaper moves in tiny circles
at a very high speed, allowing the sander to move easily.
DUSTLESS SANDING
The dust bag located on the rear of your sander provides a
dust collection system for your sander. Sanding dust is
drawnupthroughtheholesofthecushionandcollectsinthe
dust bag during sanding operation. For more efficient
operation, empty dust bag when half full.

MAINTENANCE
WARNING: WHEN SERVICING USE ONLY IDENTICAL RYOBI REPLACEMENT PARTS. USE OF ANY
OTHER PARTS MAY CREATE A HAZARD OR CAUSE PRODUCT DAMAGE.
GENERAL
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, commutator, etc.
Consequently it is not recommended that this tool be used for
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.
Avoid using solvents when cleaning plastic parts. Most
plasticsaresusceptibletovarioustypesofcommercialsolvents
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.
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.
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. Follow the recommended cord sizes on the
chart provided to determine the minimum wire size required in an extension cord.
Extension Cord Length
0-100 Feet
Wire Gauge Size (A.W.G.)
16
When working with your tool outdoors, use an extension cord suitable for outdoor use and so marked. Outdoor use extension
cords are marked with the letters "WA" on the cord's jacket.
CAUTION: Keep extension cords away from the sanding area and position the cord so that it will not get caught on lumber,
tools, etc., when sanding.
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.
