GENERAL POWER TOOL SAFETY
WARNINGS
WARNING:
Read all safety
warnings, instructions, illustrations and
specifications provided with this power
tool. Failure to follow all instructions listed
below may result in electric shock, fire and/
or serious injury.
SAVE ALL WARNINGS AND
INSTRUCTIONS FOR FUTURE
REFERENCE.
The term “power tool” in the warnings
refers to your mains-operated (corded)
power tool or battery-operated (cordless)
power tool.
WORK AREA SAFETY
1. Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
2. 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.
3. Keep children and bystanders away
while operating a power tool. Distractions
can cause you to lose control.
ELECTRICAL SAFETY
1. 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. Unmodied plugs
and matching outlets will reduce the risk of
electric shock.
2. 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.
3. Do not expose power tools to rain or
wet conditions. Water entering a power tool
will increase the risk of electric shock .
4. Do not abuse the cord. Never use the
cord for carrying, pulling or unplugging the
power tool. Keep the cord away from heat,
oil, sharp edges or moving parts. Damaged
or entangled cords increase the risk of
electric shock .
5. 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.
6. If operating a power tool in a damp
location is unavoidable, use a ground-fault
circuit interrupter (GFCI) protected supply.
Use of a GFCI reduces the risk of electric shock.
PERSONAL SAFETY
1. Stay alert, watch what you are doing
and use common sense when operating a
power tool. Do not use the tool while tired
or under the inuence of drugs, alcohol, or
medication. A moment of inattention while
operating power tools may result in serious
personal injury.
2. Use personal protective equipment.
Always wear eye protection. Protective
equipment, such as a dust mask, non-skid
safety shoes, hard hat, or hearing protection,
used for appropriate conditions, will reduce
the risk of personal injuries.
3. Prevent unintentional starting. Ensure
that the switch is in the off-position before
connecting to the power source and/or
battery pack, picking up or carrying the
tool. Carrying power tools with your nger
on the switch or energizing power tools that
have the switch on invites accidents.
4. 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.
Page 5
SAFETY INSTRUCTIONS
5. Do not overreach. Keep proper footing
and balance at all times. This enables better
control of the power tool in unexpected
situations.
6. 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.
7. If devices are provided for the
connection of dust extraction and
collection facilities, ensure that these are
connected and properly used. Use of these
devices can reduce dust-related hazards.
8. Do not let familiarity gained from
frequent use of tools allow you to become
complacent and ignore tool safety
principles. A careless action can cause
severe injury within a fraction of a second.
POWER TOOL USE AND CARE
1. 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.
2. 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.
3. Disconnect the plug from the power
source and/or remove the battery pack,
if detachable, 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.
4. 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.
5. Maintain power tools and accessories.
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.
6. Keep cutting tools sharp and clean.
Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are
easier to control.
7. Use the power tool, accessories
and tool bits etc. in accordance with
these instructions, 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.
8. Keep handles and grasping surfaces
dry, clean and free from oil and grease.
Slippery handles and grasping surfaces do
not allow for safe handling
BATTERY TOOL USE
AND CARE
1. Recharge only with the charger
specified by the manufacturer. A charger
that is suitable for one type of battery pack
may create a risk of re when used with
another battery pack.
2. Use power tools only with specifically
designated battery packs. Use of any other
battery packs may create a risk of injury and
re.
3. 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 burns or a re.
4. Under abusive conditions, liquid may
be ejected from the battery; avoid contact.
If contact accidentally occurs, flush with
water. If liquid contacts eyes, additionally
seek medical help. Liquid ejected from the
battery may cause irritation or burns.
Page 6
SAFETY INSTRUCTIONS
5. Do not use a battery pack or tool that
is damaged or modified. Damaged or
modied batteries may exhibit unpredictable
behavior resulting in re, explosion or risk of
injury.
6. Do not expose a battery pack or tool
to fire or excessive temperature. Exposure
to re or temperature above 212 °F (100 °C)
may cause explosion.
7. Follow all charging instructions and
do not charge the battery pack or tool
outside the temperature range specified
in the instructions. Charging improperly or
at temperatures outside the specied range
may damage the battery and increase the
risk of re.
SERVICE
1. Have your power tool serviced by a
qualified repair person using only identical
replacement parts. This will ensure that the
safety of the power tool is maintained.
2. Never service damaged battery
packs. Service of battery packs should
only be performed by the manufacturer or
authorized service providers.
SAFETY WARNINGS FOR DRILLS
SAFETY INSTRUCTIONS FOR
ALL OPERATIONS
1. Hold the power tool by insulated
gripping surfaces, when performing an
operation where the cutting accessory may
contact hidden wiring. Cutting accessory
contacting a “live” wire may make exposed
metal parts of the power tool “live” and
could give the operator an electric shock.
SAFETY INSTRUCTIONS WHEN
USING LONG DRILL BITS
1. Never operate at higher speed than
the maximum speed rating of the drill bit.
At higher speeds, the bit is likely to bend if
allowed to rotate freely without contacting
the workpiece, resulting in personal injury.
2. Always start drilling at low speed
and with the bit tip in contact with the
workpiece. At higher speeds, the bit is likely
to bend if allowed to rotate freely without
contacting the workpiece, resulting in
personal injury.
3. Apply pressure only in direct line
with the bit and do not apply excessive
pressure. Bits can bend causing breakage
or loss of control, resulting in personal injury.

TWO-SPEED GEARBOX (FIG. 7)
The drill/driver has a two-speed gearbox for
drilling or driving in low (1) or high (2) speed
ranges. A slide switch is located on the
top of the drill/driver to select either low or
high speed range. The speed range choice
depends on the material and the application.
Use the low speed (1) for high power and
torque applications and high speed (2) for
fast drilling or driving applications.
When using drill/driver in the low speed
range, the speed will decrease and the drill/
driver will have more power and torque. Use
the low speed for starting holes without a
center punch, drilling metals or plastic,
drilling ceramics, or in applications requiring
a higher torque.
High speed is better for drilling wood and
wood composites.
NOTICE:
• Never adjust the speed while the tool is
running. Failure to obey this caution could
result in serious damage to the drill/driver.
• Make sure that the two-speed gearbox
switch is fully engaged in the front or the

which to rotate the chuck in order to tighten
or loosen the chuck jaws on the bit.
WARNING:
Do not hold the chuck
with one hand and use the power of the
drill/driver to tighten the chuck jaws on
the drill bit. The chuck 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.
FIG. 8
TORQUE ADJUSTMENT (FIG. 9)
FIG. 9
To Decrease Torque
The torque clutch can be adjusted to any
of 18 different settings (17 driving and 1
drilling). The higher the torque setting,
the more force the drill/driver produces to
turn an object in either low or high rotation
speed.
When using the drill/driver for different
driving applications, increase or decrease
the torque in order to help prevent damage
to screw heads, threads, workpiece, etc.
Adjust the torque by rotating the torque-
adjustment ring. The proper setting
depends on the application 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 get 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.
CAUTION:
Do not change the
torque setting when the tool is running.

7. 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.
DRILLING IN WOOD
For maximum performance, use high-speed
steel (available separately) or brad-point
bits (available separately) for wood drilling.
1. 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.
2. Begin drilling at a very low speed to
prevent the bit from slipping off the starting
point.
3. Increase speed as the drill bit bites into
the material.
DRILLING IN METAL
For maximum performance, use high-speed
steel bits (available separately) 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 efciency.
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 that
allow cutting without overheating the bit.
Applying too much pressure will:
• Overheat the drill/driver
• Wear the bearings
• Bend or burn bits
• Produce off-center or irregularly shaped
holes
SCREWDRIVER OPERATION
1. Select the desired speed/torque range
to match the planned operation.
2. Attach the desired driving bit into the
chuck.
3. Make a few practice runs in a scrap
piece before working.

GENERAL POWER TOOL SAFETY
WARNINGS
WARNING:
Read all safety
warnings, instructions, illustrations and
specifications provided with this power
tool. Failure to follow all instructions listed
below may result in electric shock, re and/
or serious injury.
SAVE ALL WARNINGS AND
INSTRUCTIONS FOR FUTURE
REFERENCE.
The term “power tool” in the warnings
refers to your mains-operated (corded)
power tool or battery-operated (cordless)
power tool.
WORK AREA SAFETY
1. Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
2. 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.
3. Keep children and bystanders away
while operating a power tool. Distractions
can cause you to lose control.
ELECTRICAL SAFETY
1. 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. Unmodied plugs
and matching outlets will reduce risk of
electric shock.
2. 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.
3. Do not expose power tools to rain or
wet conditions. Water entering a power tool
will increase the risk of electric shock.
4. 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.
5. 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.
6. If operating a power tool in a damp
location is unavoidable, use a ground fault
circuit interrupter (GFCI) protected supply. Use
of an GFCI reduces the risk of electric shock.
PERSONAL SAFETY
1. Stay alert, watch what you are doing
and use common sense when operating a
power tool. Do not use a power tool while
you are tired or under the influence of
drugs, alcohol or medication. A moment of
inattention while operating power tools may
result in serious personal injury.
2. Use personal protective equipment.
Always wear eye protection. Protective
equipment such as a dust mask, non-skid
safety shoes, hard hat or hearing protection
used for appropriate conditions will reduce
personal injuries.
3. Prevent unintentional starting. Ensure
the switch is in the off-position before
connecting to power source and/or battery
pack, picking up or carrying the tool.
Carrying power tools with your nger on the
switch or energizing power tools that have
the switch on invites accidents.
4. 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.
Page 5
SAFETY INSTRUCTIONS
5. Do not overreach. Keep proper footing
and balance at all times. This enables better
control of the power tool in unexpected
situations.
6. Dress properly. Do not wear loose
clothing or jewelry. Keep your hair and
clothing away from moving parts. Loose
clothes, jewelry or long hair can be caught
in moving parts.
7. If devices are provided for the
connection of dust extraction and
collection facilities, ensure these are
connected and properly used. Use of dust
collection can reduce dust-related hazards.
8. Do not let familiarity gained from
frequent use of tools allow you to become
complacent and ignore tool safety
principles. A careless action can cause
severe injury within a fraction of a second.
POWER TOOL USE AND CARE
1. 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.
2. 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.
3. Disconnect the plug from the power
source and/or remove the battery pack,
if detachable, 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.
4. 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.
5. Maintain power tools and accessories.
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.
6. Keep cutting tools sharp and clean.
Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are
easier to control.
7. Use the power tool, accessories
and tool bits etc. in accordance with
these instructions, 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.
8. Keep handles and grasping surfaces
dry, clean and free from oil and grease.
Slippery handles and grasping surfaces do
not allow for safe handling and control of the
tool in unexpected situations.
BATTERY TOOL USE AND CARE
1. Recharge only with the charger
specified by the manufacturer. A charger
that is suitable for one type of battery pack
may create a risk of re when used with
another battery pack.
2. Use power tools only with specifically
designated battery packs. Use of any other
battery packs may create a risk of injury and
re.
3. 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 burns or a re.
4. Under abusive conditions, liquid may
be ejected from the battery; avoid contact.
If contact accidentally occurs, flush with
water. If liquid contacts eyes, additionally
seek medical help. Liquid ejected from the
battery may cause irritation or burns.
Page 6
SAFETY INSTRUCTIONS
5. Do not use a battery pack or tool that
is damaged or modified. Damaged or
modied batteries may exhibit unpredictable
behavior resulting in re, explosion or risk of
injury.
6. Do not expose a battery pack or tool
to fire or excessive temperature. Exposure
to re or temperature above 212 °F (100 °C)
may cause explosion.
7. Follow all charging instructions and
do not charge the battery pack or tool
outside the temperature range specified
in the instructions. Charging improperly or
at temperatures outside the specied range
may damage the battery and increase the
risk of re.
SERVICE
1. Have your power tool serviced by a
qualified repair person using only identical
replacement parts. This will ensure that the
safety of the power tool is maintained.
2. Never service damaged battery
packs. Service of battery packs should

OPERATION
POWER INDICATOR (Fig. 2)
This Lithium-Ion battery pack is equipped with
a power indicator that displays the battery
pack’s charge status. Press the power-
indicator button to display the LED lights.
The LED lights will stay lit for approximately
4 seconds.
LOW CAPACITY WARNING
If one LED on the power indicator begins to
flash, the battery pack’s charge is under 20%
capacity and should be recharged soon.
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, power to
the tool will drop quickly.
The power indicator will begin to display
four flashing LED lights when it is completely
discharged. When this happens, remove
the tool from the workpiece and charge the
battery pack as needed.
BATTERY PROTECTION
To protect the battery from damage and
prolong its life, the battery pack circuitry
will turn off the battery pack if it becomes
overloaded or if the temperature becomes too
high during use. This may happen in extremely
high torque, binding and stalling situations.
The battery pack will begin normal operation
when it cools down.
The power indicator will display four flashing
LED lights if the circuitry detects a momentary
overload. You can conveniently reset the
battery pack by releasing the power-tool
trigger. Press the power-indicator button
again to display the remaining charge.
NOTICE: If the power indicator continues to
flash four LED lights after resetting, place
the battery pack on the charger to evaluate
the battery condition.
NOTICE: A significantly reduced run time
after fully charging the battery pack indicates
that the battery is near the end of its usable
life and must be replaced.

OPERATION
COLD WEATHER OPERATION
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
The Lithium-Ion battery can be charged at
any time and will not develop a “memory”
when charged after only a partial discharge.

pack charge before recharging. Remove
the battery pack from the tool when it is
convenient for you and your job.
1. Use the power indicator to determine when
you need to recharge the battery pack.
2. You can “top-off” your battery pack’s
charge before starting a big job or long
period of use.
3. Due to Lithium-Ion’s 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.
