GENERAL SAFETY RULES  
Dress properly. Do not wear loose clothing or  
jewelry. Contain long hair. Keep your hair, cloth-  
ing, and gloves away from moving parts. Loose  
clothes, jewelry, or long hair can be caught in mov-  
ing parts.  
WARNING:  
Read and understand all instructions. Failure to fol-  
low all instructions listed below, may result in elec-  
tric shock, fire and/or serious personal injury.  
Avoid accidental starting. Be sure switch is off  
before plugging in. Carrying tools with your finger  
on the switch or plugging in tools that have the switch  
on, invites accidents.  
SAVE THESE INSTRUCTIONS  
Work Area  
Remove adjusting keys or wrenches before turn-  
ing the tool on. A wrench or a key that is left at-  
tached to a rotating part of the tool may result in  
personal injury.  
Keep your work area clean and well lit. Cluttered  
benches and dark areas invite accidents.  
Do not operate power tools in explosive atmo-  
spheres, such as in the presence of flammable  
liquids, gases, or dust. Power tools may create  
sparks which may ignite the dust or fumes.  
Do not overreach. Keep proper footing and bal-  
ance at all times. Proper footing and balance en-  
ables better control of the tool in unexpected situa-  
tions. Do not use on a ladder or unstable support.  
Keep bystanders, children, and visitors away  
while operating a power tool. Distractions can  
cause you to lose control.  
Use safety equipment. Always wear eye protec-  
tion. Dust mask, nonskid safety shoes, hard hat, or  
hearing protection must be used for appropriate con-  
ditions.  
Electrical Safety  
Double insulated tools are equipped with a po-  
larized 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 a polarized outlet.  
Do not change the plug in any way. Double insu-  
Tool Use and Care  
Use clamps or other practical way to secure and  
support the workpiece to a stable platform. Hold-  
ing the work by hand or against your body is un-  
stable and may lead to loss of control.  
Do not force tool. Use the correct tool for your  
application. The correct tool will do the job better  
and safer at the rate for which it is designed.  
lation  
eliminates the need for the three-wire  
grounded power cord and grounded power supply  
system.  
Do not use tool if switch does not turn it on or  
off. Any tool that cannot be controlled with the switch  
is dangerous and must be repaired.  
Avoid body contact with grounded surfaces,  
such as pipes, radiators, ranges, and refrigera-  
tors. There is an increased risk of electric shock if  
your body is grounded.  
Disconnect the plug from power source before  
making any adjustments, changing accessories,  
or storing the tool. Such preventive safety mea-  
sures reduce the risk of starting the tool acciden-  
tally.  
Don’t expose power tools to rain or wet condi-  
tions. Water entering a power tool will increase the  
risk of electric shock.  
Do not abuse the cord. Never use the cord to  
carry the tools or pull the plug from an outlet.  
Keep cord away from heat, oil, sharp edges, or  
moving parts. Replace damaged cords immedi-  
ately. Damaged cords increase the risk of electric  
shock.  
Store idle tools out of the reach of children and  
other untrained persons. Tools are dangerous in  
the hands of untrained users.  
Maintain tools with care. Keep cutting tools sharp  
and clean. Properly maintained tools with sharp  
cutting edges are less likely to bind and are easier  
to control.  
When operating a power tool outside, use an  
outdoor extension cord marked “W-A” or “W”.  
These cords are rated for outdoor use and reduce  
the risk of electric shock.  
Check for misalignment or binding of moving  
parts, breakage of parts, and any other condi-  
tion that may affect the tool’s operation. If dam-  
aged, have the tool serviced before using. Many  
accidents are caused by poorly maintained tools.  
Personal Safety  
Stay alert, watch what you are doing and use  
common sense when operating a power tool. Do  
not use tool while tired or under the influence of  
drugs, alcohol, or medication. A moment of inat-  
tention while operating power tools may result in  
serious personal injury.  
Use only accessories that are recommended by  
the manufacturer for your model. Accessories that  
may be suitable for one tool, may become hazard-  
ous when used on another tool.

GENERAL SAFETY RULES  
When servicing a tool, use only identical replace-  
Service  
ment parts. Follow instructions in the Mainte-  
nance section of this manual. Use of unauthorized  
parts or failure to follow Maintenance Instructions  
may create a risk of electric shock or injury.  
Tool service must be performed only by quali-  
fied repair personnel. Service or maintenance per-  
formed by unqualified personnel could result in a risk  
of injury.  
SPECIFIC SAFETY RULES  
Hold tool by insulated gripping surfaces when performing an operation where the cutting tool may contact  
hidden wiring or its cord. Contact with a “live” wire will make exposed metal parts of the tool “live” and shock the operator.  
Make sure your extension cord is in good condi-  
tion. When using an extension cord, be sure to  
use one heavy enough to carry the current your  
product will draw. 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. An undersized cord will cause a  
drop in line voltage resulting in loss of power and  
overheating.  
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. Following this rule will reduce the risk  
of electric shock, fire, or serious injury.  
Always wear safety glasses. Everyday eye-  
glasses have only impact-resistant lenses; they  
are NOT safety glasses. Following this rule will re-  
duce the risk of serious personal injury.  
Protect your lungs. Wear a face or dust mask if  
the operation is dusty. Following this rule will re-  
duce the risk of serious personal injury.  
Inspect for and remove all nails from lumber  
before driving screws. Following this rule will  
reduce the risk of serious personal injury.  
Protect your hearing. Wear hearing protection  
during extended periods of operation. Following  
this rule will reduce the risk of serious personal in-  
jury.  
Drugs, alcohol, medication. Do not operate tool  
while under the influence of drugs, alcohol, or  
any medication. Following this rule will reduce the  
risk of electric shock, fire, or serious personal injury.  
Inspect tool cords periodically and, if damaged,  
have repaired at your nearest Factory Service  
Center or otherAuthorized Service Organization.  
Constantly stay aware of cord location. Follow-  
ing this rule will reduce the risk of electric shock or  
fire.  
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.  
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 func-  
tion. Check for alignment of moving parts, bind-  
ing of moving parts, breakage of parts, mount-  
ing, 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. Following this rule will  
reduce the risk of shock, fire, or serious injury.  
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.  
Do not abuse cord. Never carry the tool by the  
cord or yank it to disconnect it from the recep-  
tacle. Keep cord away from heat, oil, and sharp  
edges. Following this rule will reduce the risk of elec-  
tric shock or fire.  
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.

MAINTENANCE  
WARNING:  
When servicing use only identical Ryobi replacement parts. Use of any other parts may create a hazard or cause  
product damage.  
GENERAL  
EXTENSION CORDS  
All parts represent an important part of the double  
insulation system and should be serviced only at an  
authorized service center.  
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.  
Avoid using solvents when cleaning plastic parts. Most  
plastics are susceptible to damage from various types  
of commercial solvents and may be damaged by their  
use. Use clean cloths to remove dirt, carbon dust, etc.  
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.  
WARNING:  
WARNING:  
Do not at any time let brake fluids, gasoline, petro-  
leum-based products, penetrating oils, etc. come in  
contact with plastic parts. They contain chemicals that  
can damage, weaken or destroy plastic.  
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.  
It has been found that electric tools are subject to  
accelerated wear and possible premature failure when  
theyareusedonfiberglassboats,sportscars,wallboard,  
spacklingcompounds,orplaster.Thechipsandgrindings  
from these materials are highly abrasive to electric tool  
parts, such as bearings, brushes, commutators, etc.  
Whenusingthistoolonthesetypematerialsforextended  
periods of time, it is extremely important that the tool is  
cleaned frequently by blowing with an air jet.  
Extension cords suitable for use with your screwdriver  
are available at your nearest authorized service center.  
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 normal operating conditions. Therefore, no  
further lubrication is required.  
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.
