• 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.
• Do not expose a battery pack or tool to fire or ex
-
cessive temperature.
Exposure to fire or temperature
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 im-

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
RATCHETS
• Hold 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
power tool “live” and could give the operator an
electric shock.
•
Maintain labels and nameplates.
These carry
important information. If unreadable or missing, contact
a MILWAUKEE service facility for a free replacement.

WARNING
Some dust created by power sanding,
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.
