GENERAL SAFETY RULES
WARNING: Read and understand all instructions.
Failure to follow all instructions listed below, may result in electric shock, fire and/or serious personal injury,
SAVE THESE INSTRUCTIONS Work Area
■ Keep your work area clean and well lit. Cluttered
benches and dark areas invite accidents.
■ Do not operate power tools in expiosive atmo
spheres, such as in the presence of flammabie iiquids, gases, or dust. Power tools create sparks
which may ignite the dust or fumes.
■ Keep bystanders, children, and visitors away while
operating a power tool. Distractions can cause you
to lose control.

Electrical Safety

■ Do not abuse the cord. Never use the cord to carry the charger. Keep cord away from heat, oil, sharp
edges, or moving parts. Replace damaged cords immediately. Damaged cords may create a fire.
■ A battery operated tool with integral batteries or a
separate battery pack must be recharged only with the specified charger for the battery. A charger that
may be suitable for one type of battery may create a risk of fire when used with another battery. Use battery only with charger listed.
MODEL BATTERY PACK CHARGER
315.271220 Item No. 9-11031 Item No. g-11040
Use battery operated tool only with specifically
designated battery pack. Use of any other batteries
may create a risk of fire. Use only with battery pack
listed.

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 inatten
tion while operating power tools may result in serious
personal injury,
■ Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, clothing,
and gloves away from moving parts. Loose clothes,
jewelry, or long hair can be caught in moving parts.
■ Avoid accidental starting. Be sure switch is in the
locked or off position before inserting battery
pack. Carrying tools with your finger on the switch or
inserting the battery pack into a tool with the switch on, invites accidents.
■ Remove adjusting keys or wrenches before turn ing the tool on. A wrench or a key that is left attached
to a rotating part of the tool may result in personal injury.
■ Do not overreach. Keep proper footing and bal ance at all times. Proper footing and balance enable
better control of the tool in unexpected situations.
■ Use safety equipment. Always wear eye protection.
Dust mask, non-skid safety shoes, hard hat, or hearing protection must be used for appropriate conditions.

GENERAL SAFETY RULES

Tool Use and Care

■ Use clamps or other practical way to secure and
support the workpiece to a stable platform. Holding
the work by hand or against your body is unstable 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,
■ Do not use tool if switch does not turn it on or off.
A tool that cannot be controlled with the switch is
dangerous and must be repaired.
■ Disconnect battery pack from tool or place the switch
in the locked or off position before making any adjust ments, changing accessories, or storing the tool. Such
preventive safety measures reduce risk of starting the tool accidentally.
■ Store idle tools out of reach of children and other
untrained persons. Tools are dangerous in the hands
of untrained users.
■ When battery pack is not in use, keep it away from other metal objects like: paper clips, coins, keys, nails, screws, or other smalt metal objects that can make a connection from one terminal to another.
Shorting the battery terminals together may cause sparks, burns, or a fire.
■ 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.
Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the tool's operation. If damaged, have the tool serviced before using. Many accidents are caused by
poorly maintained tools.
■ Use only accessories that are recommended by the manufacturer for your model. Accessories that
may be suitable for one tool, may create a risk of injury
when used on another tool.

Service

Tool service must be performed only by qualified
repair personnel. Service or maintenance performed
by unqualified personnel could result in a risk of injury.
■ When servicing a tool, use only identical replace
ment parts. Follow instructions in the Maintenance
section of this manual. Use of unauthorized parts or
failure to follow Maintenance Instructions may create a
risk of shock or injury.
SPECIFIC SAFETY RULES AND/OR SYMBOLS
Hold tool by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring. Contact with a "live" wire will make exposed metal parts of the tool "live" and shock the operator.

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.
■ 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.

Important Rules for Battery Tools

■ Battery tools do not have to be plugged into an electrical outlet; therefore, they are always in
operating condition. Be aware of possible hazards when not using your battery tool or when chang-
ing accessories. Following this rule will reduce the
risk of electric shock, fire, or serious personal injury.

■ Make sure power supply is normal house voltage,
120 volts, 60 Hz, AC only.
■ Connect charger to power supply.
■ Attach battery pack to charger by aligning raised ribs on battery pack with grooves in charger, then slide
battery back onto charger. See Figure 7.
If after one hour red light is still flashing, this indicates a defective battery pack and should be replaced.
Green light on indicates battery pack is fully charged and slow charging to maintain battery pack.
Yellow light on and red light flashing indicates defective battery pack. Return battery pack to your nearest Sears
Repair Center for checking or replacing.
■ When your battery pack becomes fully charged, the red light
will turn OFF and the green light will turn ON.
■ After normal usage, 1 hour of charging time is required to be fully charged. A minimum charge time of 1-1/2 hours is
required to recharge a completely discharged tool.
■ The battery pack will become slightly warm to the touch while
charging. This is normal and does not indicate a problem.
■ Do not place charger in an area of extreme heat or
cold. It will work best at normal room temperature.
■ When the batteries become fully charged, unplug your charger from power supply and remove the battery
pack.

LED FUNCTION OF CHARGER

LED WILL BE LIGHTED TO INDICATE STATUS OF CHARGER AND BATTERY PACK:
■ Red LED Lighted = Fast Charging Mode.
■ Green LED Lighted = Fully Charged And Slow
Charging To Maintain Battery Pack.
■ Red LED Flashing = Hot Or Deeply Discharged Battery Pack. Also Defective Battery Pack After 1
Hour.
■ Yellow LED Lighted and Red LED Flashing = Defective Battery Pack.
Red light should turn on. Red light indicates fast
charging mode.
If red light is flashing, this indicates battery pack is
deeply discharged or hot.
If battery pack is hot, red light should become steady after battery pack has cooled down.
If battery pack is deeply discharged, red light should become steady after voltage has increased, normally within 60 minutes.

IMPORTANT INFORMATION FOR RECHARGING HOT BATTERIES

Under extreme continuous use, the batteries in your battery pack will become hot. You should let a hot battery pack cool down for approximately 1 hour before attempt ing to recharge. When the battery pack becomes dis charged and is hot, this will cause the red light on your
battery charger to flash. When battery pack cools down, red light will glow continuously indicating fast charging mode, 1 hour charge time. Once the battery pack cools down, it will recharge battery pack in fast charging mode as normal.
Note: This situation only occurs when extreme continuous
use of your drill causes the batteries to become hot. It
does not occur under normal circumstances. Refer to "CHARGING BATTERY PACK" for normal recharging of
batteries. If the charger does not charge your battery pack under normal circumstances, return both the battery pack and charger to your nearest Sears repair center for electrical check.

OPERATION
APPLICATIONS (Use drill-driver only for the purpose listed below)
Drilling in wood.
Drilling in ceramics, plastics, fiberglass, and lami nates.
Drilling in both hard and soft metals.
Using driving accessories, such as driving screws with screwdriver bits.
Mixing paints.

LEVEL DRILLING

See Figure 14.
A convenient feature provided on your drill is a level. It is recessed in the motor housing on top and end of your driil. It can be used to keep drill bits level during most drilling operations.

DRILLING

See Figure 15.
Fig. 14
Fig. 15
When drilling hard smooth surfaces use a center punch to mark desired hole location. This will prevent the drill bit from slipping off center as the hole is started. However, the low speed feature allows starting holes without center punching if desired. To accomplish this, simply operate your drill at a low 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: Be prepared for binding or bit
breakthrough. When these situations occur, 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 not prepared, this loss of control can result in possible serious 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.
