h ) 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.
5) Battery Tool Use and Care
a ) 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 fire when used with another
battery pack.
b ) Use power tools only with specifically designated
battery packs. Use of any other battery packs may create a
risk of injury and fire.
c ) 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 fire.
d ) 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.
e ) Do not use a battery pack or tool that is damaged
or modified. Damaged or modified batteries may exhibit
unpredictable behavior resulting in fire, explosion or risk
of injury.
f ) Do not expose a battery pack or tool to fire or
excessive temperature. Exposure to fire or temperature
above 265 °F (129 °C) may cause explosion.
g ) 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 specified range may damage the
battery and increase the risk of fire.
6) Service
a ) 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.
b ) Never service damaged battery packs. Service of
battery packs should only be performed by the manufacturer
or authorized service providers.
Additional Safety Rules for Impact Drivers
• Hold the power tool by insulated gripping surfaces,
when performing an operation where the fastener may
contact hidden wiring. Fasteners contacting a "live" wire
may make exposed metal parts of the tool "live" and could give
the operator an electric shock.

WARNING: Impact drivers are not torque drivers or
torque wrenches. DO NOT use this tool for tightening
fasteners to specified torques. An independent, calibrated
torque measurement device such as a torque driver or
torque wrench should be used when under tightened or over
tightened fasteners can lead to the failure of the joint.
• Use clamps or another practical way to secure and
support 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.
• Wear safety goggles or other eye protection.
Hammering and drilling operations cause chips to fly.
Flying particles can cause permanent eye damage.
• Accessories and tools get hot during operation. Wear
gloves when touching them.
• Do not operate this tool for long periods of time.
Vibration caused by tool action may be harmful to your
hands and arms. Use gloves to provide extra cushion and
limit exposure by taking frequent rest periods.
Additional Safety Information

WARNING: Never modify the product or any part of it.
Damage or personal injury could result.

WARNING: ALWAYS use safety glasses. Everyday
eyeglasses are NOT safety glasses. Also use face or dust
mask if cutting operation is dusty. ALWAYS WEAR CERTIFIED
SAFETY EQUIPMENT:
• ANSI Z87.1 eye protection (CAN/CSA Z94.3),
• ANSI S12.6 (S3.19) hearing protection,
• NIOSH/OSHA/MSHA respiratory protection.

WARNING: Some dust created by power sanding, sawing,
grinding, drilling, and other construction activities contains
chemicals known to the State of California to cause cancer,
birth defects or other reproductive harm. Some examples of
these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry
products, and
• arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how
often you do this type of work. To reduce your exposure to
these chemicals: work in a well ventilated area, and work with
approved safety equipment, such as those dust masks that are
specially designed to filter out microscopic particles.
• Avoid prolonged contact with dust from power
sanding, sawing, grinding, drilling, and other
construction activities. Wear protective clothing and
wash exposed areas with soap and water. Allowing dust
to get into your mouth, eyes, or lay on the skin may promote
absorption of harmful chemicals.

WARNING: Use of this tool can generate and/or disperse
dust, which may cause serious and permanent respiratory or
other injury. Always use NIOSH/OSHA approved respiratory
protection appropriate for the dust exposure. Direct particles
away from face and body.

WARNING: Always wear proper personal hearing
protection that conforms to ANSI S12.6 (S3.19) during
use. Under some conditions and duration of use, noise from
this product may contribute to hearing loss.

CAUTION: When not in use, place tool on its side on
a stable surface where it will not cause a tripping or
falling hazard. Some tools will stand upright but may be
easily knocked over.
• Air vents often cover moving parts and should be
avoided. Loose clothes, jewelry or long hair can be caught in
moving parts.
