• Under abusive conditions, liquid may be ejected
from the battery; avoid contact. If contact ac-
cidentally occurs, flush with water. If liquid con-
tacts eyes, additionally seek medical help. Liquid
ejected from the battery may cause irritation or burns.
• Do not use a battery pack or tool that is dam-
aged or modified. Damaged or modified batteries
may exhibit unpredictable behavior resulting in fire,
explosion or risk of injury.
• Do not expose a battery pack or tool to fire or
excessive temperature. Exposure to fire or tem-
perature above 265°F (130°C) may cause explosion.
• 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.
SERVICE
• 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.
• Never service damaged battery packs. Service
of battery packs should only be performed by the
manufacturer or authorized service providers.
SPECIFIC SAFETY RULES
FOR IMPACT DRIVER
• Hold the power tool by insulated gripping sur-
faces, when performing an operation where the
fastener may contact hidden wiring. Fasteners
contacting a "live" wire may make exposed metal
parts of the power tool "live" and could give the
operator an electric shock.
• Wear ear protectors when impact drilling. Expo-
sure to noise can cause hearing loss.
• Use only sockets and other accessories specifi-
cally designed for use on impact wrenches and
drivers. Other sockets and accessories might shatter
or break causing injury.

WARNING
plications that produce a consid-
erable amount of dust, use an OSHA compliant
dust extraction solution in accordance with the
solution's operating instructions.
• Always use common sense and be cautious when
using tools. It is not possible to anticipate every
situation that could result in a dangerous outcome.
Do not use this tool if you do not understand these
operating instructions or you feel the work is beyond

WARNING
sawing, grinding, drilling, and other
construction activities contains chemicals known to
cause cancer, birth defects or other reproductive
harm. Some examples of these chemicals are:
• lead from lead-based paint
• 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.
