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.  
KNOW YOUR CORDLESS TOOL  
READ ALL INSTRUCTIONS  
Safe operation of this cordless tool requires that you read  
and understand this Operator's Manual and all labels affixed  
to the tool. Learn its applications and limitations as well as  
the potential hazards related to a cordless tool. Keep this  
manual readily available for future reference.  
KEEP THE WORK AREA CLEAN. Cluttered work  
areas and work benches invite injuries.  
CONSIDER WORK AREA ENVIRONMENT. Keep  
work area well lit. Do not use tool in presence of  
flammable liquids or gases.  
IMPORTANT  
GUARD AGAINST ELECTRICAL SHOCK BY  
PREVENTING BODY CONTACT WITH  
GROUNDED SURFACES. For example: Pipes,  
radiators, ranges, refrigerator enclosures.  
Servicing of a tool requires extreme care and knowledge of  
the system and should be performed only by a authorized  
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.  
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.  
WARNING:  
STORE IDLE TOOLS. When not in use tools should  
be stored in a dry and high or locked-up place - out  
of the reach of children.  
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 this operator's  
manual and review it frequently for continuing safe  
operation, and instructing others who may use this tool.  
DON'T FORCE TOOL. It will do the job better and  
safer at the rate for which it was designed.  
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.  
WARNING:  
When using power tools, basic safety precautions should  
always be followed to reduce the risk of fire, electric shock,  
and personal injury, including the following precautions.  
WEAR PROPER APPAREL. Do not wear loose  
clothing or jewelry that can get caught in tool's  
moving parts and cause personal injury. Rubber  
gloves and nonskid footwear are recommended

Before drilling into walls, ceilings, or floors, make  
sure that there is no concealed electrical wiring  
inside.  
MAINTAIN TOOLS WITH CARE. Keep tools sharp  
atalltimes,andcleanforbestandsafestperformance.  
Follow instructions for lubricating and changing  
accessories.  
WARNING:  
Drilling into electrical wiring can cause drill bit  
and chuck to become electrically live. Do not  
touch the chuck or metal housing when drilling  
into a wall; grasp only the insulated handle(s)  
provided on the tool.

OPERATION  
WARNING:  
Always wear safety goggles or safety glasses with side  
shields when operating tool. Failure to do so could result  
in objects being thrown into your eyes, resulting in  
possible serious injury.  
DRILLING  
See Figure 12.  
2 2  
1 8  
2 0  
When drilling hard, smooth surfaces, use a center punch to  
mark the desired hole location. This will prevent the drill bit  
from slipping off center as the hole is started. However, the  
lower speed feature allows starting holes without center  
punching if desired. To accomplish this, simply operate your  
drill at lower speed until the hole is started.  
The material to be drilled should be secured in a vise or with  
clamps to keep it from turning as the drill bit rotates.  
Hold tool firmly and place the bit at the point to be drilled.  
Depress the switch trigger to start tool.  
Move the drill bit into the workpiece, applying only enough  
pressure to keep the bit cutting. Do not force or apply side  
pressure to elongate a hole.  
WARNING:  
Fig. 12  
Be prepared for binding or bit breakthrough. When these  
situations occur, the drill has a tendency to grab and kick  
opposite to the direction of rotation, and could cause loss  
of control when breaking through material. If you are not  
prepared, this loss of control can result in possible serious  
injury.  
WARNING:  
Do not force tool. Forcing tool can result in jamming and  
loss of balance or footing, which could result in personal  
injury.  
When drilling metals, use a light oil on the drill bit to keep it  
from overheating. The oil will prolong the life of the bit and  
increase the drilling action.  
If the bit jams in workpiece or if the drill stalls, release switch  
trigger immediately. Remove the bit from the workpiece and  
determine the reason for jamming.

MAINTENANCE  
DO NOT ABUSE POWER TOOLS. Abusive practices can  
damage the tool, as well as the workpiece.  
WARNING:  
When servicing use only identical Ryobi replacement  
parts. Use of any other parts can create a hazard or cause  
product damage.  
WARNING:  
Do not attempt to modify this tool or create accessories  
not recommended for use with this tool. Any such  
alteration or modification is misuse and could result in a  
hazardous condition leading to possible serious personal  
injury.  
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  
a clean cloth to remove dirt, oil, grease, etc.  
CAUTION:  
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 may  
damage, weaken, or destroy plastics.  
CAUTION:  
Any repairs requiring disassembly should only be  
performed by a Ryobi Authorized Service Center. For  
the repair center nearest you, call 1-800-525-2579.  
BATTERIES  
Your drill is equipped with Nickel-Cadmium rechargeable  
batteries. Length of service from each charging will depend  
on the type of work you are doing.  
Store and charge your batteries in a cool area.

battery life.  
The batteries in this tool have been designed to provide  
maximum trouble-free life. However, like all batteries, they  
will eventually wear out. Do not disassemble the battery  
pack and attempt to replace the batteries. Handling of  
these batteries, especially when wearing rings and jewelry,  
could result in a serious burn.  
Never store batteries in a discharged condition. Wait for  
battery to cool and charge immediately.  
All batteries gradually lose their charge. The higher the  
temperature, the quicker they lose their charge. If you  
store your tool for long periods of time without using it,  
recharge the batteries every month or two. This practice  
will prolong battery life.  
To obtain the longest possible battery life, we suggest the  
following:  
CAUTION:  
Your drill-driver contains special high temperature  
batteries to help prevent battery damage when left on  
charge for extended periods of time. However, once the  
batteries become fully charged, we recommend that you  
unplug the charger/charging assembly from power supply  
and remove it from battery pack.
