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 caution or warning. May be used in conjunction with other symbols or pictographs.
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
Your Ryobi power tool is double insulated. This means you
are separated from the tool's electrical system by two complete
sets of electrical insulation. This extra layer of insulation is
intended to protect the user from electrical shock due to a
break in the wiring insulation. 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 FACTORY
SERVICE CENTER or other AUTHORIZED SERVICE
ORGANIZATION 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 owner's manual
and review frequently for continuing safe operation, and
instructing others who may use this tool.

READ ALL INSTRUCTIONS
1. KNOW YOUR POWER TOOL. Read owner'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.
12. PROTECT YOUR LUNGS. Wear a face or
dust mask if operation is dusty.
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. Both hands are needed to operate
the tool.
16. DON'T OVERREACH. Keep proper footing
and balance at all times. Do not use 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
attachments, blades, bits, cutters, 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.
22. OUTDOOR USE EXTENSION CORDS.
When tool is used outdoors, use only
extension cords suitable for use outdoors.
Outdoor approved cords are marked with
the suffix W-A, for example - SJTW-A or
SJOW-A.
23. KEEP BITS CLEAN AND SHARP. Sharp bits
minimize stalling and kickback.
