WORK AREA SAFETY
ELECTRICAL SAFETY
Failure to follow the warnings and instructions
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.
1. Keep the 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
ammable 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.
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. Unmodied 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 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.
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 inuence 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
that the switch is in the o󰀨-position before
connecting to a 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.
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.

GERNERAL SAFETY RULES
POWER TOOL USE AND CARE
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.
9. 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.
10. Keep handles dry, clean, and free from oil
and grease. Slippery hands cannot safely
control the power tool.
11. 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.
12. 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.
13. Protect your hearing. Wear hearing
protection during extended periods of
operation. Following this rule will reduce
the risk of serious person injury.
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. Check for
misalignment or binding of moving parts,
breakage of parts and any other condition
that may a󰀨ect 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, 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 di󰀨erent 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.
9. 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.
10. Know your power tool. Read the product
manual carefully. Learn the applications
and limitations, as well as the specic,
potential hazards related to this tool.
Following this rule will reduce the risk of
electric shock, re or serious injury.
11. 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.
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 more safely at the rate for which it was
designed.
2. Do not use the power tool if the switch
does not turn it on and o󰀨. 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 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.

1. Make sure that the switch is in the OFF
position before inserting the battery pack.
Inserting the battery pack into power tools
that have the switch ON invites accidents.
2. Recharge only with the charger specied
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.
3. Use power tools only with specically
designated battery packs. Use of any other
battery packs may create a risk of injury
and re.
4. 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.
5. Under abusive conditions, liquid may be
ejected from the battery; avoid contact.
If contact accidentally occurs, ush with
water. If liquid contacts eyes, additionally
seek medical help. Liquid ejected from the
battery may cause irritation or burns.
6. 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, re, or serious personal
injury.
7. Do not place battery tools or their batteries
near re or heat. This will reduce the risk of
explosion and possible injury.
8. Do not crush, drop or damage the 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.
9. A damaged battery is subject to explosion.
Properly dispose of a dropped or damaged
battery immediately.
10. Do not charge a battery tool in a damp
or wet location. Following this rule will

ADDITIONAL SAFETY RULES
FOR IMPACT DRIVER
1. Hold power tools by insulated gripping
surfaces when performing 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
tool “live” and shock the operator.
2. Use clamps or other practical way to
support and secure the workpiece to a
stable platform. Holding the work by hand
or against your body is unstable and may
lead to loss of control.
3. Do not drill, fasten or break into existing
walls or other blind areas where electrical
wiring may exist. If this situation is
unavoidable, disconnect all fuses or circuit
breakers supplying the worksite.
4. Always wear safety goggles or eye
protection when using this tool.
5. Bits, sockets, and tools get hot during
operation. Wear gloves when touching
them.
6. Wear ear protectors when using the tool
for extended periods. Prolonged exposure
to high intensity noise can cause hearing
loss.
7. Use thick, cushioned gloves and limit the
exposure time by taking frequent rest
periods. Vibration caused by hammer-drill
or Imapct wrench action may be harmful to
your hands and arms.
8. Secure the material being fastened. Never
hold it in your hand or across your legs.
Unstable support can cause loss of control
and injury.
9. Avoid accidental starting. Be sure the
forward/reverse switch is in the OFF
position before inserting a battery pack.
Carrying appliances with your nger on
the switch or inserting the battery pack
into an appliance with the switch on invites
accidents.
10. Remove battery pack before changing
accessories. Accidental starting may
occur because battery appliances with
a battery inserted are in the operative
condition.
11. Be prepared for a reaction torque when
“seating” or removing a fastener. The tool
housing may tend to twist in the opposite
direction of bit rotation when “seating” or
removing a fastener, depending on the
torque setting of the tool.
12. Do not run the tool while carrying it at
your side. A spinning bit could become
entangled with clothing and injury may
result.
13. Place the tool onto the fastener only when
the tool is switched OFF. Rotating driver
tools can slide o󰀨 the fastener.
14. Do not use this tool as a drill. Tools
equipped with shut-o󰀨 clutches are not
designed for drilling applications. The
output drive can shut o󰀨 automatically
and without warning.
15. Be careful when driving long screws.
There is a risk of the tool sliding o󰀨 the
fastener head, depending on type of
socket or bit used. First test the run-down
of a fastener and pay attention during the
screw-driving process to ensure you do
not injury yourself if the tool bit or socket
slides o󰀨 of the fastener.
16. For best results, your battery tool should
be charged in a location where the
temperature is more that 32° F (0° C)
but less that 104°F (40°C). Do not store
outside or in vehicles.

when the trigger switch on the wrench 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. The
POWER BAR will begin to display four
ashing LED lights when the battery
is completely discharged. When this
happens, remove the tool from the
workpiece, and charge the battery pack
as needed.
• Use the POWER BAR to determine when
you need to recharge the battery pack.
• You can “top-o󰀨” your battery pack’s
charge before starting a big job or long
period of use.
NOTE: The POWER BAR may also display
four ashing LED lights due to an overload
or high temperature situation.
The Lithium-Ion battery can be charged
at any time and will not develop a
“memory” when charged after only a partial
discharge. It is not necessary to run down
the battery pack charge before recharging.
Remove the battery pack from the tool
when convenient for you and your job.

1. Install the correct bit.
2. Apply just enough pressure to keep the bit
engaged on the screw.
3. Apply minimal pressure to the trigger
switch initially. Increase the speed only
when full control can be maintained.
Variable speed control must be used with
caution for driving nuts and bolts with
socket set attachments. The best technique
is to start slowly, increasing speed as the
nut or bolt runs down. Set the nut or bolt
snugly by slowing the tool to a stop. If this
procedure is not followed, the tool will have
a tendency to torque or twist in your hands
when the nut or bolt seats.
