GENERAL SAFETY RULES
WARNING!
READ AND UNDERSTAND ALL INSTRUCTIONS. Fail-
ure 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
designated 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 a re 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 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 sup-
port 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
application. 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
cutting 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 clean-
ing. Never use brake fluids, gasoline, petroleum-based
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 re-
pair 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 per-
forming 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 care-
fully. 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 s afety 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 Protect your lungs. Wear a face or dust mask if the
operation is dusty. Following this rule will reduce the
risk of serious personal injury.
n Protect your hearing. Wear hearing protection during
extended periods of operation. Following this rule will
reduce the risk of serious personal injury.
n Battery tools do not have to be plugged into an elec-
trical 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 When servicing a tool, use only identical replacement
parts. Follow instructions in the Maintenance section
of this manual. Use of unauthorized parts or failure to fol-
low Maintenance Instructions may create a risk of shock
or injury.
n Do not place battery tools or their batteries near fire
or heat. This will reduce the risk of explosion and pos-
sibly 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 charg e batt er y tool in a damp or wet
location. 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 conditions, bat-
tery 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.

OPERATION
WARNING:
Battery tools are always in operating condition. Therefore, switch should always be locked when not in use or
carrying at your side.
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 the
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:
Be prepared for binding at 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.
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.
LEVEL DRILLING
See Figure 11.
Another 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 horizontal drilling
operations.
Fig. 10
LEVEL
Fig. 11
OPERATION
ADJUSTABLE TORQUE CLUTCH
See Figure 12.
When using the drill-driver for various driving applications,
it becomes necessary to increase or decrease the torque
in order to help prevent the possibility of damaging screw
heads, threads, workpiece, etc. In general, torque should
correspond to the intensity of the screw diameter. If the
torque is too high or the screws too small, the screws may
be damaged or broken.
The torque is adjusted by rotating the torque adjustment
ring. The torque is greater when the torque adjustment ring
is set on a higher setting. The torque is less when the torque
adjustment ring is set on a lower setting.
The proper setting depends on the type of material and the
size of screw you are using.
ADJUSTING TORQUE
n Identify the twenty four torque indicator settings located
on the front of the drill.
n Rotate adjusting ring to the desired setting.
• 1 - 4 ..................For driving small screws
• 5 - 8 ..................For driving screws into soft material
• 9 - 12 ................For driving screws into soft and hard
materials
• 13 - 16 ..............For driving screws in hard wood
• 17 - 20 ..............For driving large screws
