GENERAL SAFETY RULES
WARNING! READ AND UNDERSTAND ALL IN-
STRUCTIONS. Failure to follow all instructions listed
below may result in electric shock, fire and/or serious
personal injury.
SAVE THESE INSTRUCTIONS
WORK AREA
n Keep your work area clean and well lit. Cluttered
benches and dark areas invite accidents.
n Do not operate power tools in explosive atmo-
spheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks which
may ignite the dust or fumes.
n Keep bystanders, children, and visitors away while
operating a power tool. Distractions can cause you to
lose control.
ELECTRICAL SAFETY
n 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.
n Use battery operated tool only with specifically des-
ignated battery pack. Use of any other batteries may
create a risk of fire.
n Use battery only with charger listed.
MODEL BATTERY PACK CHARGER
315.270850 130145009 Model No. 315.110400
Item No. 9 11034 (Item No.140223001)
n 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.
PERSONAL SAFETY
n Stay alert, watch what you are doing and use com-
mon sense when operating a power tool. Do not
use tool while tired or under the influence of drugs,
alcohol, or medication. A moment of inattention while
operating power tools may result in serious personal
injury.
n 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.
n 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.
n Remove adjusting keys or wrenches before turning
the tool on. A wrench or a key that is left attached to a
rotating part of the tool may result in personal injury.
n Do not overreach. Keep proper footing and balance
at all times. Proper footing and balance enable better
control of the tool in unexpected situations.
n Use safety equipment. Always wear eye protection.
Dust mask, non-skid safety shoes, hard hat, or hearing
protection must be used for appropriate conditions.
n Do not wear loose clothing or jewelry. Contain long
hair. Loose clothes, jewelry, or long hair can be drawn
into air vents.
n Do not use on a ladder or unstable support. Stable
footing on a solid surface enables better control of the
tool in unexpected situations.
TOOL USE AND CARE
n 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.
n Do not force tool. Use the correct tool for your ap-
plication. The correct tool will do the job better and
safer at the rate for which it is designed.
n 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.
n Disconnect battery pack from tool or place the
switch in the locked or off position before making
any adjustments, changing accessories, or storing
the tool. Such preventive safety measures reduce the
risk of starting the tool accidentally.
n Store idle tools out of reach of children and other
untrained persons. Tools are dangerous in the hands
of untrained users.
n When battery pack is not in use, keep it away from
other metal objects like: paper clips, coins, keys,
nails, screws, or other small metal objects that can
make a connection from one terminal to another.
Shorting the battery terminals together may cause
sparks, burns, or a fire.
n Maintain tools with care. Keep cutting tools sharp
and clean. Properly maintained tools with sharp cut-
ting edges are less likely to bind and are easier to
control.
n 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.
n 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.
n Keep the tool and its handle dry, clean and free
from oil and grease. Always use a clean cloth when
cleaning. Never use brake fluids, gasoline, petroleumbased products, or any strong solvents to clean your
tool. Following this rule will reduce the risk of loss of
control and deterioration of the enclosure plastic.

GENERAL SAFETY RULES
SERVICE
n Tool service must be performed only by qualified
repair personnel. Service or maintenance performed
by unqualified personnel may result in a risk of injury.
SPECIFIC SAFETY RULES
n Use auxiliary handles supplied with the tool. Loss of
control can cause personal injury.
n Hold tool by insulated gripping surfaces when
performing an operation where the cutting tool may
contact hidden wiring. Contact with a “live” wire will
also make exposed metal parts of the tool “live” and
shock the operator.
n 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.
n Always wear safety glasses with side shields.
Everyday glasses have only impact resistant lenses.
They are NOT safety glasses. Following this rule will
reduce the risk of eye injury.
n 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 changing
accessories. Following this rule will reduce the risk of
electric shock, fire, or serious personal injury.
n Do not place battery tools or their batteries near
fire or heat. This will reduce the risk of explosion and
possibly injury.
n 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.
n Never use a battery that has been dropped or
received a sharp blow. A damaged battery is subject
to explosion. Properly dispose of a dropped or damaged battery immediately.
n Batteries vent hydrogen gas and can explode in
the presence of a source of ignition, such as a pilot
light. To reduce the risk of serious personal injury,
never use any cordless product in the presence of
open flame. An exploded battery can propel debris and
chemicals. If exposed, flush with water immediately.
n Do not charge battery tool in a damp or wet loca-
tion. Following this rule will reduce the risk of electric
shock.
n For best results, your battery tool should be
charged in a location where the temperature is
more than 50°F but less than 100°F. Do not store
outside or in vehicles.
n Under extreme usage or temperature condi-
tions, battery leakage may occur. If liquid comes
in contact with your skin, wash immediately with
soap and water, then neutralize with lemon juice
or vinegar. If liquid gets into your eyes, flush them
with clean water for at least 10 minutes, then seek
immediate medical attention. Following this rule will
reduce the risk of serious personal injury.

carry the charger. Do not pull the charger cord rather
than the plug when disconnecting from receptacle.
Damage to the cord or charger could occur and create
an electric shock hazard. Replace damaged cords immediately.
n Make sure cord is located so that it will not be
stepped on, tripped over, come in contact with
sharp edges or moving parts or otherwise subjected to damage or stress. This will reduce the risk of
accidental falls, which could cause injury, and damage
to the cord, which could result in electric shock.
n Keep cord and charger from heat to prevent
damage to housing or internal parts.
n Do not let gasoline, oils, petroleum-based products,
etc. come in contact with plastic parts. They contain
chemicals that can damage, weaken, or destroy plastic.
n An extension cord should not be used unless
absolutely necessary. Use of improper extension cord
could result in a risk of fire and electric shock. If
extension cord must be used, make sure:
a. That pins on plug of extension cord are the
same number, size and shape as those of
plug on charger.
b. That extension cord is properly wired and in
good electrical condition; and
c. That wire size is large enough for AC ampere
rating of charger as specified below:
Cord Length (Feet) 25' 50' 100'
Cord Size (AWG) 16 16 16

serviceman when service or repair is required. Incorrect reassembly may result in a risk of electric shock or
fire.
n Unplug charger from outlet before attempting any
maintenance or cleaning to reduce the risk of
electric shock.
n Disconnect charger from the power supply when
not in use. This will reduce the risk of electric shock
or damage to the charger if metal items should fall into
the opening. It also will help prevent damage to the
charger during a power surge.
n Risk of electric shock. Do not touch uninsulated
portion of output connector or uninsulated battery
terminal.
n 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 to prevent misuse of the product and
possible 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.
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.

LED FUNCTIONS OF CHARGER
LED WILL BE ON TO INDICATE STATUS OF
CHARGER AND BATTERY PACK:
n Red LED on = Fast charging mode.
n Red LED flashing = When battery pack is inserted into
charger, indicates hot battery pack or that battery pack
is out of normal temperature range.
n Green LED on = Fully charged and in maintenance
charge mode.
n Yellow LED on and red LED flashing = Deeply
discharged or defective battery pack.
n No LED on = Defective charger or battery pack.
CHARGING A COOL BATTERY PACK
If battery pack is below normal temperature range, the
red LED on charger will flash. Allow battery pack to reach
normal temperature, then the red LED will become steady.
NOTE: If the charger does not charge the battery pack
under normal circumstances, return both the battery pack
and charger to your nearest Sears Repair Center for
electrical check.
n Charge the battery pack only with the charger provided.
n Make sure the power supply is normal household
voltage, 120 V, 60 Hz, AC only.
n Connect the charger to the power supply.
n Attach battery pack to charger by aligning raised rib on
battery pack with grooves in charger, then slide battery
pack onto charger. See Figure 2.
n Normally the red LED on charger will come on. This
indicates the charger is in fast charging mode.
n Red LED should remain on for approximately 1 hour
then the green LED will come on. Green LED on
indicates battery pack is fully charged and charger is
in maintenance charge mode.
NOTE: The green LED will remain on until the battery
pack is removed from the charger or charger is
disconnected from the power supply.
n If the yellow LED comes on and the red LED flashes,
this indicates a deeply discharged or defective battery
pack. Allow the battery pack to remain in the charger
for 60 minutes. When the battery pack reaches normal
voltage range, the red LED should become steady. If
the red LED does not come on after 60 minutes, this
may indicate a defective battery pack and should be

CHARGING A HOT BATTERY PACK
When using the tool continuously, the batteries in the
battery pack will become hot. You should let a hot battery
pack cool down for approximately 30 minutes before
attempting to recharge. When the battery pack becomes
discharged and is hot, this will cause the red LED to flash
instead of remaining steady. After 30 minutes, reinsert
the battery pack in the charger. If the red LED continues
to flash, return battery pack to your nearest Sears Repair
Center for checking or replacing.
NOTE: This situation only occurs when continuous use of
the tool causes the batteries to become hot. It does not
occur under normal circumstances. Refer to CHARGING
A COOL BATTERY PACK for normal recharging of

NOTE: You might hear a whistling or ringing noise from
the switch during use. Do not be concerned; this is a
normal part of the switch function.
FORWARD / REVERSE / CENTER LOCK
See Figure 5.
The direction of bit rotation is reversible and is controlled
by a selector located above the switch trigger. With the
drill held in normal operating position, the direction of
rotation selector should be positioned to the left of the
switch trigger for drilling. The drilling direction is reversed
when the selector is to the right of the switch trigger.
Setting the switch trigger in the OFF (center lock) position
helps reduce the possibility of accidental starting when not
in use.
CAUTION: To prevent gear damage, always allow
the chuck to come to a complete stop before changing the direction of rotation.
To stop the drill, release the switch trigger and allow the
chuck to come to a complete stop.
NOTE: The drill will not run unless the direction of rotation
selector is pushed fully to the left or right.
Avoid running the drill at low speeds for extended periods
of time. Running at low speeds under constant usage may
cause the drill to become overheated. If this occurs, cool
the drill by running it without a load and at full speed.
WARNING: Do not hold the chuck body with one
hand and use the power of the drill to tighten the
chuck jaws on the drill bit. The chuck body could slip
in your hand, or your hand could slip and come in
contact with the rotating drill bit. This could cause an
accident resulting in serious personal injury.
TWO-SPEED GEAR TRAIN
See Figure 7.
The drill has a two-speed gear train designed for drilling or
driving at LO (1) or HI (2) speeds. A slide switch is located
on top of the drill to select either LO (1) or HI (2) speed.
When using drill in the LO (1) speed range, speed will
decrease and unit will have more power and torque. When
using drill in the HI (2) speed range, speed will increase
and unit will have less power and torque. Use LO (1)
speed for high power and torque applications and HI (2)

USING THE AUXILIARY HANDLE
See Figure 12.
An auxiliary handle is packed with the drill for ease of
operation and to help prevent loss of control. The handle
can be rotated 360°, and it can also be mounted on the
opposite side for left hand use.
To adjust the auxiliary handle assembly:
n Loosen the handle assembly by rotating the wing
screw counterclockwise.
n Rotate the auxiliary handle assembly to the desired
operating position.
n Securely tighten by rotating the wing screw clockwise.
To prevent possible loss of control, the auxiliary handle
should be checked periodically for tightness. Do not operate the drill with the auxiliary handle loose.

DRILLING
See Figures 13 - 14.
A level is located on top of the motor housing to help keep
the drill bit level during use.
n Check the direction of rotation selector for the correct
setting (forward or reverse).�
n Secure the material to be drilled in a vise or with
clamps to keep it from turning as the drill bit rotates.�
n Hold the drill firmly and place the bit at the point to be
drilled.�
n Depress the switch trigger to start the drill.
n Move the drill bit into the workpiece, applying only
enough pressure to keep the bit cutting. Do not force
the drill or apply side pressure to elongate a hole. Let
the tool do the work.
WARNING: Be prepared for binding at bit break-
through. 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.

LEVEL
n 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.
n 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.
n If the bit jams in the workpiece or if the drill stalls,
stop the tool immediately. Remove the bit from the
workpiece and determine the reason for jamming.
NOTE: This drill has an electric brake. When the switch
trigger is released, the chuck stops turning. When the
brake is functioning properly, sparks will be visible through
the vent slots on the housing. This is normal and is the
action of the brake.
