DRILLING  
See Figure 10.  
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:  
TO DECREASE  
TORQUE  
Be prepared for binding or breakthrough. When these  
situations occur, the drill has a tendency to grab and kick  
in the opposite direction, 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.

MAINTENANCE  
DO NOT ABUSE POWER TOOLS. Abusive practices can  
damage the tool, as well as the work piece.  
WARNING:  
When servicing use only identical Ryobi replacement  
parts. Useofanyotherpartsmaycreateahazardorcause  
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.  
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 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's battery pack is equipped with Nickel-Cadmium  
rechargeable batteries. Length of service from each charg-  
ing will depend on the type of work you are doing.  
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 from power supply and remove it from  
battery pack.  
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.  
To obtain the longest possible battery life, we suggest the  
following:  
OVERLOAD  
Store and charge your batteries in a cool area.  
Temperatures above normal room temperature will  
shorten battery life.  
(For Models R10520 and R10530 only)  
Your drill has a built-in overload protector to protect the motor  
during overloading or prolonged use. The overload protector  
automatically activates to break the circuit. When this occurs,  
allow your drill to cool a few seconds before resuming  
operation.  
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.
