GENERAL SAFETY RULES
WARNING: Read and understand all instructions. Failure to follow all
instructions listed below may result in electric shock, fire, and/or serious
personal injury. The term "power tool" in all of warnings listed below refers to
corded power tools or battery-operated (cordless) power tools.
READ AND SAVE THESE INSTRUCTIONS
WORK AREA SAFETY
®
®
Keep the work area clean and well lit. Cluttered or dark areas invite accidents.
Do not operate power tools in explosive environments, such as in the pres-
ence of flammable liquids, gases, or dust. Power tools create sparks, which
may ignite the dust or fumes.
Keep children and bystanders away while operating a power tool. Distrac-
tions may cause you to lose control.
ELECTRICAL SAFETY
Avoid body contact with grounded surfaces, such as pipes, radiators,
ranges, and refrigerators. There is an increased risk of electric shock if your
body is grounded.
Power tool plugs must match the outlet. Never modify the plug in any way.
Do not use any adapter plugs with grounded power tools. Unmodified plugs
and matching outlets will reduce the risk of electric shock.
Do not expose power tools to rain or wet conditions. Water entering a power
tool will increase the risk of electric shock.
Do not abuse the cord. Never use the cord for carrying, pulling, or unplug-
ging the power tool. Keep the cord away from heat, oil, sharp edge, or mov-
ing parts. Damaged or entangled cords increase the risk of electric shock.
When operating a power tool outdoors, use an extension cord suitable for
outdoor use. Use of a cord suitable for outdoor use reduces the risk of elec-
tric shock.
• Use the battery only with the charger listed:

PERSONAL SAFETY
Stay alert, watch what you are doing, and use common sense when operat-
ing a power tool. Do not use a power 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.
Use safety equipment. Always wear eye protection. Safety equipment, such
as dust mask, non-skid safety shoes, hard hat, and hearing protection, when
used for appropriate conditions, will reduce personal injuries.
Avoid accidental starting. Make sure that the switch is in the "OFF" position
before plugging the tool into an electrical outlet. Carrying power tools with
your finger on the switch or plugging in power tools that have the power
switch "ON" invites accidents.
Remove any adjusting key or wrench before turning the power tool on. A
wrench or key left attached to a rotating part of the power tool may result in
personal injury.
Do not overreach. Keep proper footing and balance at all times. This enables
better control of the power tool in unexpected situations.
Dress properly. Do not wear loose clothing or jewelry. Keep your hair, cloth-
ing, and gloves away from moving parts. Loose clothes, jewelry, or long hair
can be caught in moving parts.
If devices are provided for the connection of dust extraction and collection
facilities, make sure that these are connected and properly used. Use of
these devices can reduce dust-related hazards.
Use clamps or another practical way to support and secure the workpiece
to a stable platform. Holding the work by hand or against your body leaves it
unstable and may lead to loss of control.
Do not use on a ladder or unstable support. Stable footing on a solid surface
enables better control of the power tool in unexpected situations.
Keep handles dry, clean, and free from oil and grease. Slippery hands cannot
safely control the power tool.
Always wear safety glasses with side shields. Everyday glasses may have
impact-resistant lenses, but they are NOT safety glasses. Following this rule
will reduce the risk of eye injury.
Protect your lungs. Wear a face or dust mask if the operation is dusty. Fol-
lowing this rule will reduce the risk of serious personal injury.
Protect your hearing. Wear hearing protection during extended periods of
operation. Following this rule will reduce the risk of serious person injury.
POWER TOOL USE AND CARE
Do not force the power tool. Use the correct power tool for your application.
The correct power tool will do the job better and more safely at the rate for
which it was designated.
Do not use the power tool if the switch does not turn it ON and OFF. Any
power tool that cannot be controlled with the switch is dangerous and must
be repaired.
Disconnect the plug from the power source and/or the battery pack from the
power tool before making any adjustments, changing accessories, or storing
power tools. Such preventive safety measures reduce the risk of starting the
power tool accidentally.
Store idle power tools out of the reach of children and do not allow persons
unfamiliar with the power tool or these instructions to operate the power tool.
Power tools are dangerous in the hands of untrained users.
Maintain power tools. Check for misalignment or binding of moving parts,
breakage of parts and any other condition that may affect the power tool's
operation. If damaged, have the power tool repaired before use. Many ac-
cidents are caused by poorly maintained power tools.
Keep cutting tools sharp and clean. Properly maintained cutting tools with
sharp cutting edges are less likely to bind and are easier to control.
Use the power tool, accessories, blades, etc. in accordance with these
instructions and in the manner intended for the particular type of power tool,
taking into account the working conditions and the work to be performed.
Use of the power tool for operations different from those intended could
result in a hazardous situation.
Hold power tools by the insulated gripping surfaces when performing any
operation in which the cutting tool may contact hidden wiring or its own
cord. Contact with a "live" wire will also make exposed metal parts of the
tool "live" and can shock the operator.
Know your power tool. Read the product manual carefully. Learn the applica-
tions 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.
Save these instructions. Refer to them frequently and use them to instruct
others who may use this tool. If you lend this tool to someone else, also lend
them these instructions.

LOW-BATTERY CAPACITY INDICATOR
If the LED worklight begins to rapidly and continuously flash when the trigger
switch on the Drill is depressed, the battery pack's power has run out, and the
battery pack should be recharged.
Unlike other battery pack types, Lithium-Ion battery packs deliver fade-free
power for their entire run time. The tool will not experience a slow, gradual loss
of power as you work. To signal that the battery pack is at the end of its run time
and needs to be charged, the power to the tool will drop quickly.
NOTE: The LED may also flash due to an overload or high temperature (see
BATTERY PROTECTION).
BATTERY PROTECTION
The battery circuitry protects the battery pack from extreme temperature, over-
discharge, and over-charge. To protect the battery from damage and prolong its
life, the battery pack circuitry will turn off the battery pack if it becomes over-
loaded or if the temperature becomes too high during use. This may happen in
extremely high torque, binding, and stalling situations. This intelligent system will
shut down your battery pack if its operating temperature exceeds 176°F (80°C)
and will begin normal operation when it returns to 32°F (0°C) - 122°F (50°C).
The LED worklight light will begin flash slowly if the battery circuitry detects a
momentary overload.
NOTE: The battery can automatically reset. If the LED continues to flash rapidly,
it is indicating that the charge is substantially diminished. Place the battery into
the charger for charging. (See BATTERY CAPACITY INDICATOR, above.)
NOTE: A significantly reduced run time after fully charging the battery pack indi-
cates that the battery is near the end of its usable life and must be replaced.
COLD WEATHER OPERATION
This Lithium-Ion battery pack will provide optimal performance in temperatures
between 32°F (0°C) and 104°F (40°C). When the battery pack is very cold, it may
"pulse" for the first minute of use to warm itself. Put the battery pack on a tool
and use the tool in a light application. After about a minute, the battery pack will
have warmed itself and will operate normally.
WHEN TO CHARGE THE BATTERY PACK
It is not necessary to run down
the battery pack charge before
recharging. The Lithium-Ion
battery can be charged at any
time and will not develop a
"memory" when charged after
only a partial discharge.
Remove the battery pack from
the tool when convenient for
you and your job. "Top off" the
battery pack charge by charg-
ing it for a time before starting a
big job or long period of use.
Fig. 2
Due to Lithium-Ion fade-free
properties, the only time it is
necessary to charge the Lithium- Ion battery pack is when the pack has reached
the end of its charge. To signal the end of charge, power to the tool will drop
quickly. Charge the battery pack as needed.
HOW TO CHARGE THE BATTERY PACK
NOTE: This Lithium-Ion battery pack is shipped partially charged. Before using it
the first time, fully charge the battery pack.
A fully discharged battery pack will charge in about 30 minutes in a surrounding
temperature between 32 ° F (0° C) and 104 ° F (40 ° C).
1. Charge the Lithium-Ion battery pack with the correct charger.
2. Connect the charger to a power supply.
3. Align the raised ribs of the battery pack with the slot in the charger.
4. Insert the battery pack into the charger (Fig. 2).
5. The charger will communicate with the battery pack to evaluate the condition of
the battery pack.
6. The green lights will flash while the battery pack is charging. After charging
is complete, the green LED on the charger will be on. The flickering red light
indicates a defective battery or a bad connection between the battery and
the charger.
7. The battery pack will fully charge if left on the charger, but it will not overcharge.
NOTE: For your convenience, the charger can operate with most generators and
inverters rated at 300 watts or higher.

DIRECTION-OF=ROTATION
SELECTOR (FORWARD/
REVERSE/CENTER
LOCK) (Fig. 5)
The direction of bit rotation is reversible and is controlled by a selector located
above the trigger switch.
With the Drill held in normal operating position:
1. Position the direction-of-rotation selector to the left of the tool for drilling.
2. Position the direction-of-rotation selector to the right of the tool for reverse.
3. Setting the switch in the OFF (center lock) position helps reduce the possi-
bility 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.
NOTE: The Drill will not run unless the direction-of-rotation selector is engaged
fully to the left or right.
ELECTRIC BRAKE
To stop the Drill, release the trigger switch and allow the chuck to come to a
complete stop. The electric brake quickly stops the chuck from rotating. This
feature engages automatically when you release the trigger switch.
KEYLESS CHUCK (Fig. 6)
The Drill has a keyless chuck to
tighten or release drill bits in the
chuck jaws. The arrows on the
chuck indicate the direction in
which to rotate the chuck body
in order to GRIP (tighten) or
OPEN (release) the chuck jaws
on the Drill bit.
_J_ 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 bit. This could
cause an accident resulting in
serious personal injury.
TWO-SPEED GEARBOX (Fig. 7)
The Drill has a two-speed
gearbox designed for drilling
or driving at LO or HI speeds.
A slide switch is located on the
top of the Drill to select either
LO or HI speed.

Two-speed gearbox switch
When using Drill in the LO
speed range, the speed will
decrease and the Drill will have more power and torque. When using the Drill in
the HI speed range, the speed will increase and the Drill will have more driving
power and twisting force (torque). Use LO speed for high power and torque
applications and HI speed for fast Drilling or driving applications.
Use LO speed for starting holes without a center punch, drilling metals or plas-
tic, drilling ceramics, or in applications requiring a higher torque (see below).
HI speed is better for drilling wood and wood composites and for using abrasive
and polishing accessories.
NOTE: Avoid running the Drill at LO speed for extended periods of time. Running
at LO speed under constant usage may cause the Drill to become overheated. If
this occurs, cool the Drill by running it without a load at HI speed.
CAUTION: Never change gears while the tool is running. Failure to obey this
caution could result in serious damage to the Drill.

justed to 17 different settings. I
The higher the torque setting,
the more force the drill produc-
es to turn an object in either LO
or HI rotation speed.
When using the Drill for different
driving applications, increase or
decrease the torque in order to
help prevent damaging screw
heads, threads, workpiece, etc.
Adjust the torque by rotating
the torque-adjustment ring. ring
To decrease torque
The proper setting depends
on the job and the type of bit,
fastener, and material you will
be using. In general, use greater
torque for larger screws. If the
torque is too high, the screws
may be damaged or broken.
For delicate operations, such
as removing a partially stripped
screw, use a low torque setting.
For operations such as drilling
into hardwood, use a higher
torque setting.

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.
6. When drilling hard, smooth surfaces, use a center punch to mark the desired
location of the hole. This will prevent the drill bit from slipping off-center as
the hole is started.
7. When drilling metals, use 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.
8. 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.
_L. WARNING: This Drill is equipped with an electric brake. When the brake is
functioning properly, sparks may be visible through the vent slots in the housing.
This is normal and results from the action of the brake.
WOOD DRiLLiNG
For maximum performance, use high-speed steel or brad-point bits for wood drilling.
1. Begin drilling at a very low speed to prevent the bit from slipping off the
starting point.
2. Increase speed as the drill bit bites into the material.
3. When drilling "through" holes, place a block of wood behind the workpiece
to prevent ragged or splintered edges on the back side of the hole.
METAL DRiLLiNG
For maximum performance, use high speed steel bits for metal or steel drilling.
1. When drilling metals, use 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.
2. Begin drilling at a very low speed to prevent the bit from slipping off the
starting point.
3. Maintain a speed and a pressure which allow cutting without overheating
the bit. Applying too much pressure will:
Overheat the Drill.
Wear the bearings.
Bend or burn bits.
Produce off-center or irregularly shaped holes.
MASONRY DRiLLiNG
For maximum performance, use carbide-tipped masonry bits when drilling holes
in brick, tile, concrete, etc.
1. Maintain a speed and a pressure which allow cutting without overheating
the bit or Drill. Applying too much pressure will:
Overheat the Drill.
Wear the bearings.
Bend or burn bits.
Produce off-center or irregular-shaped holes.
2. Apply light pressure and medium speed for best results in brick.
3. Apply additional pressure for hard materials such as concrete.
4. When drilling holes in tile, practice on a scrap piece to determine the best
speed and pressure.
5. Begin drilling at a very low speed to prevent the bit from slipping off the
starting point.
