GENERAL SAFETY RULES
WARNING!
Read all instructions. Failure to follow all
instructions listed below may result in electric
shock, fire and/or serious injury. The term “power
tool” in all of the warnings listed below refers
to your mains-operated (corded) power tool or
battery-operated (cordless) power tool.
SAVE THESE INSTRUCTIONS
WORK AREA SAFETY
 Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
 Do 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.
 Keep children and bystanders away while operating a
power tool. Distractions can cause you to lose control.
ELECTRICAL SAFETY
 Power tool plugs must match the outlet. Never modify
the plug in any way. Do not use any adapter plugs with
earthed (grounded) power tools. Unmodified plugs and
matching outlets will reduce risk of electric shock.
 Avoid body contact with earthed or grounded surfaces
such as pipes, radiators, ranges and refrigerators.
There is an increased risk of electric shock if your
body is earthed or grounded.
 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 unplugging the power tool. Keep
cord away from heat, oil, sharp edges or moving
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 electric
shock.

shoes, hard hat, or hearing protection used for appropriate
conditions will reduce personal injuries.
 Avoid accidental starting. Ensure the switch is in the
off-position before plugging in. Carrying power tools
with your finger on the switch or plugging in power tools
that have the switch on invites accidents.
 Remove any adjusting key or wrench before turning
the power tool on. A wrench or a 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, clothing 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, ensure these are
connected and properly used. Use of these devices can
reduce dust-related hazards.
 Do not wear loose clothing or jewelry. Contain long
hair. Loose clothes, jewelry, or long hair can be drawn
into air vents.
 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.
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 safer at the rate for which it was designed.
 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 accidents 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.

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.
 Always wear safety 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.
 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.
 Protect your hearing. Wear hearing protection during
extended periods of operation. Following this rule will
reduce the risk of serious personal injury.
 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.
 Do not place battery tools or their batteries near fire
or heat. This will reduce the risk of explosion and possibly
injury.
 Do not crush, drop or damage battery pack. Do not
use a battery pack or charger 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.
 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.
 Do not charge battery tool in a damp or wet location.
Following this rule will reduce the risk of electric shock.
 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.
 Under extreme usage or temperature conditions,
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

CHARGING THE BATTERY PACK
NOTE: New 24 Volt lithium-ion battery packs will not
work without first being charged. Before first time use,
charge the battery pack to activate it.
It is not necessary to drain the battery pack completely
before recharging. Lithium-ion battery packs have no
“memory” and can be recharged at any time. It is therefore
possible to charge the battery pack before extended usage
even if the battery pack is not completely drained of charge.
Use the charge level indicator to determine the amount of
charge in the battery pack.
Lithium-ion batteries deliver fade free power for their entire
run time. 24 Volt lithium-ion tools will not gradually lose
power due to decreasing battery charge. Instead, power from
the battery pack will drop from full to zero once the full charge
has been drained from the battery. Once this happens, the
tool’s power drops from full to zero, and recharging of the
battery is required

To stop the drill, release the switch trigger and allow the
chuck to come to a complete stop.
NOTE: The drill will not run unless the direction of rotation
selector is pushed fully to the left or right.
Avoid running the drill at low speeds for extended periods
of time. Running at low speeds under constant usage may
cause the drill to become overheated. If this occurs, cool the
drill by running it without a load and at full speed.
KEYLESS CHUCK
See Figure 8.
The drill has a keyless chuck to tighten or release drill bits
in the chuck jaws. The arrows on the chuck indicate which
direction to rotate the chuck body in order to CLOSE (tighten)
or OPEN (release) the chuck jaws on the drill bit.
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 drill bit. This could cause an accident
resulting in serious personal injury.

TWO-SPEED GEAR TRAIN
See Figure 9.
The drill has a two-speed gear train designed for drilling or
driving at LO (1) or HI (2) speeds. A slide switch is located on
top of the drill to select either LO (1) or HI (2) speed. When
using drill in the LO (1) speed range, speed will decrease
and unit will have more power and torque. When using drill in
the HI (2) speed range, speed will increase and unit will have
less power and torque. Use LO (1) speed for high power
and torque applications and HI (2) speed for fast drilling or
driving applications.
NOTE: If you have difficulty changing from one gear range to
the other, turn the chuck by hand until the gears engage.
CAUTION:
Never change gears while the tool is running.
Failure to obey this caution could result in serious
damage to the drill.
MODE CHANGE RING
See Figure 10.
The mode change ring allows you to quickly switch from drill
mode to drive mode.
In general, drill mode should be used for drilling and other
heavy duty applications. Drive mode should be used for
driving screws. Hammer mode should be used for hammer
drilling.

SELECTING DRIVE, DRILL, OR HAMMER
SETTING
See Figure 11.
Select the option that best matches the type of bit, fastener,
and material you will be using.
 Choose your application
 Choose the correct speed: LO (1) or HI (2)
 Choose the correct mode: Drill, Drive or Hammer.
TORQUE ADJUSTMENT
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 intensity
should correspond to the screw diameter. If the torque is
too high or the screws too small, the screws may be dam-
aged 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.
NOTE: The torque adjustment ring only functions in drive
mode.

OPERATION
INSTALLING BITS
See Figure 13.
 Lock the switch trigger by placing the direction of rotation
selector in the center position.
 Open or close the chuck jaws to a point where the opening
is slightly larger than the bit size you intend to use. Also,
raise the front of the drill slightly to keep the bit from falling
out of the chuck jaws.
 Insert the drill bit.
WARNING:
Make sure to insert the drill bit straight into the
chuck jaws. Do not insert the drill bit into the chuck
jaws at an angle then tighten, as shown in figure 14.
This could cause the drill bit to be thrown from the
drill, resulting in possible serious personal injury or
damage to the chuck.
 �Tighten the chuck jaws securely on the bit.
NOTE: Rotate the chuck body in the direction of the
arrow marked CLOSE to close the chuck jaws. Do not
use a wrench to tighten or loosen the chuck jaws.
REMOVING BITS
See Figure 13.
 Lock the switch trigger by placing the direction of rotation
selector in the center position.
 Open the chuck jaws.
NOTE: Rotate the chuck body in the direction of the
arrow marked OPEN to open the chuck jaws. Do not use
a wrench to tighten or loosen the chuck jaws.
 Remove the drill bit.

OPERATION
USING THE AUXILIARY HANDLE ASSEMBLY
See Figure 15.
An auxiliary handle assembly is packed with the drill for
ease of operation and to help prevent loss of control. The
handle can be rotated 360°, and it can also be mounted on
the opposite side for left hand use.
To adjust the auxiliary handle assembly:
 Loosen the handle assembly by turning the handle
counterclockwise.
 Rotate the handle assembly to the desired operating
position.
 Securely tighten by turning the handle assembly
clockwise.
Be sure the handle assembly is securely tightened against
the clamp. This secures the handle assembly.
NOTE: For convenience and ease of starting threads, the
hex nut has been trapped inside the molded slot in the
handle assembly.
DRILLING
See Figure 16.
 Check the direction of rotation selector for the correct
setting (forward or reverse).�
 Secure the material to be drilled in a vise or with clamps
to keep it from turning as the drill bit rotates.�
 Hold the drill firmly and place the bit at the point to be
drilled.�
 Depress the switch trigger to start the drill.
 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.
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 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.
 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 the workpiece or if the drill stalls, stop
the tool immediately. Remove the bit from the workpiece
and determine the reason for jamming.

OPERATION
WOOD DRILLING�
For maximum performance, use high speed steel bits for
wood drilling.�
 Select drill mode.�
 Begin drilling at a very low speed to prevent the bit from
slipping off the starting point. Increase the speed as the
drill bit bites into the material.�
 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.
 Select drill mode.
 Begin drilling at a very low speed to prevent the bit from
slipping off the starting point.�
 Maintain a speed and pressure which allows cutting
without overheating the bit. Applying too much pressure
will:
• Overheat the drill;
• Wear the bearings;
• Bend or burn bits; and
• Produce off-center or irregular-shaped holes.�
 When drilling large holes in metal, start with a small bit,
then finish with a larger bit. Also, lubricate the bit with oil
to improve drilling action and increase bit life.
MASONRY DRILLING
For maximum performance, use carbide-tipped masonry
impact bits when drilling holes in brick, tile, concrete, etc.
 Turn mode change ring to the hammer drill icon to select
hammer mode.�
 Apply light pressure and medium speed for best results
in brick.�
 Apply additional pressure for hard materials such as
concrete.�
 When drilling holes in tile, practice on a scrap piece to
determine the best speed and pressure. Begin drilling at
a very low speed to prevent the bit from slipping off the
starting point.�
