CHARGER IS RATED FOR 120 VOL T AC
ONLY.
Charger must be plugged into an ap-
propriate receptacle.
10.
USE ONLY RECOMMENDED ATTACH-
MENTS.
Use of an attachment not recom-
mended or sold by the battery charger or battery
pack manufacturer may result in a risk of fi re,
electric shock or personal injury.
11.
UNPLUG CHARGER
when not in use. Remove
battery pack from unplugged chargers.
12.
TO REDUCE THE RISK OF ELECTRIC
SHOCK
, always unplug charger before clean-
ing or maintenance. Do not allow water to fl ow
into AC/DC plug. Use a Ground Fault Circuit
Interrupter (GFCI) to reduce shock hazards.
13.
DO NOT BURN OR INCINERATE BATTERIES.
Batteries may explode, causing personal injury
or damage. Toxic fumes and materials are cre-
ated when batteries are burned.
14.
DO NOT CRUSH, DROP, OR DAMAGE
batter-
ies. Do not use a battery pack or charger that
has received a sharp blow, been dropped, run
over, or damaged in any way (e.g., pierced with
a nail, hit with a hammer, stepped on).
15.
DO NOT DISASSEMBLE.
Incorrect reassembly
may result in the risk of electric shock, fi re or
exposure to battery chemicals. If it is damaged,
take it to a
MILWAUKEE
service facility.
16.
BATTERY CHEMICALS CAUSE SERIOUS
BURNS.
Never allow contact with skin, eyes, or
mouth. If a damaged battery pack leaks battery
chemicals, use rubber or neoprene gloves to
dispose of it. If skin is exposed to battery fl uids,
wash with soap and water and rinse with vin-
egar. If eyes are exposed to battery chemicals,
immediately fl ush with water for 20 minutes and
seek medical attention. Remove and dispose of
contaminated clothing.
17.
DO NOT SHORT CIRCUIT.
A battery pack will
short circuit if a metal object makes a connection
between the positive and negative contacts on
the battery pack. Do not place a battery pack
near anything that may cause a short circuit,
such as coins, keys or nails in your pocket. A
short circuited battery pack may cause fi re and
personal injury.
18.
STORE YOUR BATTERY PACK AND CHAR-
GER
in a cool, dry place. Do not store battery
pack where temperatures may exceed 120°F
(50°C) such as in direct sunlight, a vehicle or
metal building during the summer.

THIS
MANUAL CONTAINS IMPORTANT SAFETY
AND OPERATING INSTRUCTIONS FOR
THE
MILWAUKEE
LITHIUM-ION COMBO
CHARGER CAT. NO. 48-59-1812 AND
MILWAUKEE
M12™ AND M18™ LI-ION
BATTERIES.
2.
BEFORE USING THE BA TTERIES AND
CHARGER, READ ALL INSTRUCTIONS AND
CAUTIONARY MARKINGS ON BA TTERY
CHARGER, BATTERY, AND TOOL.
3.
CAUTION! TO REDUCE THE RISK OF IN-
JURY, CHARG
E MILWAUKEE
M12™ AND
M18™
LITHIUM-ION BATTERIES ONLY IN
MILWAUKEE
M12™ AND M18™ LITHIUM-ION
CHARGERS.
Other types of batteries may burst
causing personal injury and damage. Do not wire
a battery pack to a power supply plug or car
cigarette lighter. Batteries will be permanently
disabled or damaged.
4.
USE
MILWAUKEE
LITHIUM-ION PACKS ONLY
ON COMPATIBLE
MILWAUKEE
LITHIUM-ION
TOOLS.
Battery pack and charger are not com-
patible with
V
™-technology or NiCd systems.
Use with other tools may result in a risk of fi re,
electric shock or personal injury.
5.
AVOID DANGEROUS ENVIRONMENTS.
Do
not charge battery pack in rain, snow, damp or
wet locations.
Do not use battery pack or charger
in the presence of explosive atmospheres (gas-
eous fumes, dust or fl ammable materials) be-
cause sparks may be generated when inserting
or removing battery pack, possibly causing fi re.
6.
CHARGE IN A WELL VENTILATED AREA.
Do not block charger vents. Keep them clear to
allow proper ventilation. Do not allow smoking
or open fl ames near a charging battery pack.
Vented gases may explode.
7.
MAINTAIN CHARGER CORD.
When unplug-
ging charger, pull plug rather than cord to reduce
the risk of damage to the electrical plug and cord.
Never carry charger by its cord. Keep cord from
heat, oil and sharp edges. Make sure cord will
not be stepped on, tripped over or subjected
to damage or stress. Do not use charger with
damaged cord or plug. Have a damaged cord
replaced immediately with identical replacement
parts (see “Maintenance”).
8.
DO NOT USE AN EXTENSION CORD UNLESS
IT IS ABSOLUTELY NECESSARY.
Using the
wrong, damaged or improperly wired extension
cord could result in the risk of fi re and electrical
shock. If an extension cord must be used, plug
the charger into a properly wired 16 gauge or
larger extension cord with pins that are the
same number, size and shape as the pins on
the charger. Make sure that the extension cord
is in good electrical condition.
