GENERAL SAFETY RULES
nDo not overreach. Keep proper footing and balance
WARNING!
at all times. Proper footing and balance enable better
control of the tool in unexpected situations.
READ AND UNDERSTAND ALL INSTRUCTIONS. Fail-
ure to follow all instructions listed below, may result in
electric shock, fire and/or serious personal injury.
nUse safety equipment. Always wear eye protection.
Dust mask, non-skid safety shoes, hard hat, or hearing
protection must be used for appropriate conditions.
nDo not wear loose clothing or jewelry. Contain long
hair. Loose clothes, jewelry, or long hair can be drawn
into air vents.
SAVE THESE INSTRUCTIONS
WORK AREA
nDo not use on a ladder or unstable support. Stable
footing on a solid surface enables better control of the
tool in unexpected situations.
nKeep your work area clean and well lit. Cluttered
benches and dark areas invite accidents.
nDo 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.
nKeep bystanders, children, and visitors away while
operating a power tool. Distractions can cause you to
lose control.
TOOL USE AND CARE
nUse 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.
nDo 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.
nDo 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.
nDisconnect 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 the risk of starting the
tool accidentally.
nStore idle tools out of reach of children and other
untrained persons. Tools are dangerous in the hands
of untrained users.
nWhen 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.
nMaintain 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.
nCheck 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.
ELECTRICAL SAFETY
nA 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.
nUse battery operated tool only with specifically
designated battery pack. Use of any other batteries
may create a risk of fire.
nUse battery only with charger listed.

nDo 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
nStay 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 inattention while
operating power tools may result in serious personal
injury.
nDress 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.
nAvoid 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 ac-
cidents.
nRemove 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.
nUse 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. Fol-
lowing this rule will reduce the risk of loss of control and
deterioration of the enclosure plastic.

instructions also to prevent misuse of the product and
possible injury.
nKeep cord and charger from heat to prevent
damage to housing or internal parts.
nDo not let gasoline, oils, petroleum-based products,
etc. come in contact with plastic parts. They contain
chemicals that can damage, weaken, or destroy plastic.
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.

OPERATION
WARNING:
Battery tools are always in operating condition. There-
fore, 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 seri-
ous injury.
Fig. 10
LEVEL
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.

OPERATION
ADJUSTABLE TORQUE CLUTCH
See Figure 12.
ADJUSTING
RING
TO DECREASE
TORQUE
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
