plugging in. Carrying tools with your finger on the switch
or plugging in tools that have the switch on invites acci-
dents.
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.
SAVE THESE INSTRUCTIONS
WORK AREA
nDo not overreach. Keep proper footing and balance
at all times. Proper footing and balance enables better
control of the tool in unexpected situations.
nKeep your work area clean and well lit. Cluttered
benches and dark areas invite accidents.
nUse safety equipment. Always wear eye protection.
Dust mask, nonskid safety shoes, hard hat, or hearing
protection must be used for appropriate conditions.
nDo not operate power tools in explosive atmospheres,
such as in the presence of flammable liquids, gases,
or dust. Power tools create sparks which may ignite the
dust or fumes.
nDo not wear loose clothing or jewelry. Contain long
hair. Loose clothes, jewelry, or long hair can be drawn
into air vents.
nKeep bystanders, children, and visitors away while
operating a power tool. Distractions can cause you to
lose control.
nDo not use on a ladder or unstable support. Stable
footing on a solid surface enables better control of the
tool in unexpected situations.
ELECTRICAL SAFETY
TOOL USE AND CARE
nDouble insulated tools are equipped with a polarized
plug (one blade is wider than the other). This plug will
fit in a polarized outlet only one way. If the plug does
not fit fully in the outlet, reverse the plug. If it still
does not fit, contact a qualified electrician to install a
polarized outlet. Do not change the plug in any way.
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 appli-
cation. The correct tool will do the job better and safer
at the rate for which it is designed.
Double insulation
eliminates the need for the three-
wire grounded power cord and grounded power supply
system.
nDo not use tool if switch does not turn it on or off.
Any tool that cannot be controlled with the switch is
dangerous and must be repaired.
nAvoid body contact with grounded surfaces such as
pipes, radiators, ranges, and refrigerators. There is an
increased risk of electric shock if your body is ground-
ed.
nDisconnect the plug from power source before mak-
ing any adjustments, changing accessories, or storing
the tool. Such preventive safety measures reduce the
risk of starting the tool accidentally.
nDon’t expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of elec-
tric shock.
nStore idle tools out of the reach of children and other
untrained persons. Tools are dangerous in the hands of
untrained users.
nDo not abuse the cord. Never use the cord to carry
the tools or pull the plug from an outlet. Keep cord
away from heat, oil, sharp edges, or moving parts.
Replace damaged cords immediately. Damaged cords
increase the risk of electric shock.
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.
n
When operating a power tool outside, use an outdoor
extension cord marked “W-A” or “W”. These cords
are rated for outdoor use and reduce the risk of electric
shock.
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.
PERSONAL SAFETY
nUse only accessories that are recommended by the
manufacturer for your model. Accessories that may be
suitable for one tool, may become hazardous when used
on another tool.
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.
nKeep 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.
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.

GENERAL SAFETY RULES
nWhen servicing a tool, use only identical replacement
SERVICE
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.
nTool 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
nHold tool by insulated gripping surfaces when per-
forming an operation where the cutting tool may
contact hidden wiring or its own cord. Contact with a
“live” wire will make exposed metal parts of the cutting
tool “live” and shock the operator.
breakage of parts, mounting, and any other conditions
that may affect its operation. A guard or other part that
is damaged should be properly repaired or replaced
by an authorized service center. Following this rule will
reduce the risk of shock, fire, or serious injury.
nDo not abuse cord. Never carry the tool by the cord
or yank it to disconnect it from the receptacle. Keep
cord away from heat, oil, and sharp edges. Following
this rule will reduce the risk of electric shock or fire.
ADDITIONAL SAFETY RULES
nKnow 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.
nMake sure your extension cord is in good condition.
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 recom-
mended for an extension cord 50 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.
nAlways wear safety glasses. Everyday eyeglasses
have only impact-resistant lenses; they are NOT
safety glasses. Following this rule will reduce the risk
of serious personal injury.
nProtect your lungs. Wear a face or dust mask if the

ELECTRICAL
DOUBLE INSULATION
EXTENSION CORDS
Doubleinsulationisaconceptinsafetyinelectricpowertools,
which eliminates the need for the usual three-wire grounded
power cord. All exposed metal parts are isolated from the
internal metal motor components with protecting insulation.
Double insulated tools do not need to be grounded.
When using a power tool at a considerable distance from
a power source, be sure to use an extension cord that has
the capacity to handle the current the tool will draw. An un-
dersized cord will cause a drop in line voltage, resulting in
overheating and loss of power. Use the chart to determine
the minimum wire size required in an extension cord. Only
round jacketed cords listed by Underwriter’s Laboratories
(UL) should be used.
WARNING:
The double insulated system is intended to protect the
user from shock resulting from a break in the tool's in-
ternal insulation. Observe all normal safety precautions
to avoid electrical shock.
When working outdoors with a tool, use an extension cord
that is designed for outside use. This type of cord is desig-
nated with "WA" on the cord's jacket.
Before using any extension cord, inspect it for loose or
exposed wires and cut or worn insulation.
Important: Servicing of a tool with double insulation requires
extreme care and knowledge of the system and should be
performedonlybyaqualifiedservicetechnician. Forservice,
we suggest you return the tool to your nearest authorized
service center for repair. Always use original factory replace-
ment parts when servicing.

BIT STORAGE
See Figure 7.
WARNING:
When not in use, bits provided with your drill can be
placed in the storage area located on the bottom of
your drill as shown in figure 7.
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. Ifnotprepared, thislossofcontrolcanresult
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.

DRILLING
See Figure 8.
Two levels are recessed in the motor housing of your
drill-driver. One is located on top, while the other is
located on the end. They can be used to keep drill bits
level during both horizontal and vertical drilling opera-
tions.
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.
