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.

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 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. Ev-
eryday 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 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.

and/or serious personal injury.
n Before using battery charger, read all instructions
and cautionary markings in this manual, on battery
charger, battery, and product using battery to prevent
misuse of the products and possible injury or damage.
CAUTION: To reduce the risk of electric shock or
damage to the charger and battery, charge only
nickel-cadmium rechargeable batteries as specifically designated on your charger. Other types of
batteries may burst, causing personal injury or
damage.
n Never use a battery that has been dropped or re-
ceived a sharp blow. A damaged battery is subject to
explosion. Properly dispose of a dropped or damaged
battery immediately.
n Do not expose charger to wet or damp conditions.
Water entering charger will increase the risk of electric
shock.
n Do not use any attachment or accessory not rec-
ommended by the battery charger manufacturer.
Attachments and accessories that may be suitable
for one tool may become hazardous when used on
another tool.
n Do not abuse cord or charger. Never use the cord to
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 dam-
age 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 ab-
solutely 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
NOTE: AWG = American Wire Gage
n Do not operate charger with a damaged cord or
plug, which could cause shorting and electric shock. If
damaged, have the charger replaced by an authorized
serviceman.
n Do not operate charger if it has received a sharp
blow, been dropped, or otherwise damaged in any
way. Take it to an authorized serviceman for electrical
check to determine if the charger is in good working
order.
n Do not disassemble charger. Take it to an authorized
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 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 con-
tains 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.

WARNING: Always wear safety goggles or safety
glasses with side shields when operating tools.
Failure to do so could result in objects being thrown
into your eyes, resulting in possible serious injury.
DRILLING
See Figure 12.
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
the 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.
LEVEL
See Figure 11.
A convenient feature provided with the drill is a level. It is
recessed in the motor housing on top of the drill. It can be
used to keep drill bit level during drilling operations.
LEVEL

Fig. 12
WARNING: Be prepared for binding at 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

BATTERIES
The battery pack for this tool is equipped with nickel-cadmium rechargeable batteries. Length of service from each
charging will depend on the type of work you are doing.
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 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:
n Remove the battery pack from the charger once it is
fully charged and ready for use.
For battery pack storage longer than 30 days:
n Store the battery pack where the temperature is below
80°F.
n Store battery packs in a "discharged" condition.
n Insert hex key into chuck and tighten chuck jaws se-
curely. Tap hex key sharply with a mallet in a clockwise
direction. This will tighten chuck on the spindle.
n Open the chuck jaws and remove hex key.
n Tighten the chuck screw.
NOTE: The chuck screw has left hand threads.
