RULES FOR SAFE OPERATION
The purpose of safety symbols is to attract your attention to possible dangers. The safety symbols, and the
explanations with them, deserve your careful attention and understanding. The safety warnings do not by
themselves eliminate any danger. The instructions or warnings they give are not substitutes for proper accident
prevention measures.
SYMBOL MEANING
SAFETY ALERT SYMBOL:
Indicates danger, warning, or caution. May be used in conjunction with other symbols or pictographs.
DANGER: Failure to obey a safety warning will result in serious injury to yourself or to others. Always
follow the safety precautions to reduce the risk of fire, electric shock and personal injury.
WARNING: Failure to obey a safety warning can result in serious injury to yourself or to others. Always
follow the safety precautions to reduce the risk of fire, electric shock and personal injury.
CAUTION: Failure to obey a safety warning may result in property damage or personal injury to yourself
or to others. Always follow the safety precautions to reduce the risk of fire, electric shock and personal
injury.
NOTE: Advises you of information or instructions vital to the operation or maintenance of the equipment.
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.
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.
WARNING:
Do not attempt to operate this tool until you have read
thoroughly and understand completely all instructions,
safety rules, etc. contained in this manual. Failure to
comply can result in accidents involving fire, electric
shock, or serious personal injury. Save operator's manual
and review frequently for continuing safe operation, and
instructing others who may use this tool.

RULES FOR SAFE OPERATION
READ ALL INSTRUCTIONS
1. 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.
2. GUARD AGAINST ELECTRICAL SHOCK by
preventing body contact with grounded
surfaces. For example: Pipes, radiators,
ranges, refrigerator enclosures.
3. KEEP GUARDS IN PLACE and in working
order.
4. KEEP WORK AREA CLEAN. Cluttered areas
and benches invite accidents.
5. AVOID DANGEROUS ENVIRONMENT. Don't
use power tool in damp or wet locations or
expose to rain. Keep work area well lit.
6. KEEP CHILDREN AND VISITORS AWAY.
All visitors should wear safety glasses and be
kept a safe distance from work area. Do not
let visitors contact tool or extension cord.
7. STORE IDLE TOOLS. When not in use tools
should be stored in a dry and high or lockedup place - out of the reach of children.
8. DON'T FORCE TOOL. It will do the job better
and safer at the rate for which it was designed.
9. USE RIGHT TOOL. Don't force small tool or
attachment to do the job of a heavy duty tool.
Don't use tool for purpose not intended - for
example - A circular saw should never be
used for cutting tree limbs or logs.
10. WEAR PROPER APPAREL. Do not wear
loose clothing or jewelry that can get caught
in the tool's moving parts and cause personal
injury. Rubber gloves and nonskid footwear
are recommended when working outdoors.
Wear protective hair covering to contain long
hair and keep it from being drawn into nearby
air vents.
11. ALWAYS WEAR SAFETY GLASSES.
Everyday eyeglasses have only impactresistant lenses; they are NOT safety glasses.
13. PROTECT YOUR HEARING. Wear hearing
protection during extended periods of
operation.
14. DON'T ABUSE CORD. Never carry tool by
cord or yank it to disconnect from receptacle.
Keep cord from heat, oil and sharp edges.
15. SECURE WORK. Use clamps or a vise to
hold work. It's safer than using your hand and
it frees both hands to operate the tool.
16. DON'T OVERREACH. Keep proper footing
and balance at all times. Do not use while
standing on a ladder or unstable support.
17. MAINTAIN TOOLS WITH CARE. Keep tools
sharp at all times, and clean for best and
safest performance. Follow instructions for
lubricating and changing accessories.
18. DISCONNECT TOOLS. When not in use,
before servicing, or when changing or
adjusting attachments, blades, bits, cutters,
sandpaper, etc., all tools should be
disconnected from power supply.
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. AVOID ACCIDENTAL STARTING. Don't
carry plugged-in tools with finger on switch.
Be sure switch is off when plugging in.
21. 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.
12. PROTECT YOUR LUNGS. Wear a face or
dust mask if operation is dusty.
Look for this symbol to point out important safety precautions.
It means attention!!! Your safety is involved.

Outdoor approved cords are marked with
the suffix W-A, for example - SJTW-A or
SJOW-A.
23. 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.
24. KEEP HANDS AWAY FROM SANDING
AREA.
25. NEVER USE IN AN EXPLOSIVE ATMOSPHERE. Normal sparking of the motor could
ignite fumes.

34. WHEN SERVICING USE ONLY IDENTICAL
RYOBI REPLACEMENT PARTS.
35. MAKE THE WORKSHOP CHILD-PROOF
with padlocks, master switches, or by
removing starter keys.
36. POLARIZED PLUGS. To reduce the risk of
electric shock, this tool has 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 the proper outlet. Do not
change the plug in any way.
37. SAVE THESE INSTRUCTIONS. Review them
frequently and use them to instruct others
who may use this tool. If you loan someone
this tool, loan them these instructions also.
28. KEEP HANDLES DRY, CLEAN, AND FREE
FROM OIL AND GREASE. Always use a
clean cloth when cleaning. Never use brake
fluids, gasoline, petroleum-based products or
any strong solvents to clean your tool.
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
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 unless indicated
elsewhere in this instruction manual.
31. DO NOT USE TOOL IF SWITCH DOES NOT
TURN IT ON AND OFF. Have defective
switches replaced by an authorized service
center.
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.
