This operator's manual contains important safety
and operating instructions for MILWAUKEE M4™
Lithium-Ion batteries and the MILWAUKEE M4™
Lithium-Ion battery charger. Before using the batter-
ies and charger, read this operator's manual, your
tool operator's manual, and all labels on the battery,
charger and tool.
1.
CAUTION
TO REDUCE THE RISK OF IN-
JURY, CHARGE MILWAUKEE
M4™ LITHIUM-ION BATTERIES ONLY IN
MILWAUKEE M4™ LITHIUM-ION CHARGERS.
Other types of chargers may cause personal
injury or damage. Do not wire a battery to a
power supply plug or car cigarette lighter. Batter-
ies will be permanently disabled or damaged.
2.
USE MILWAUKEE M4™ LITHIUM-ION BATTER-
IES ONLY ON MILWAUKEE M4™ LITHIUM-ION
TOOLS.
Use with other tools may result in a risk
of fire, electric shock or personal injury.
3.
AVOID DANGEROUS ENVIRONMENTS.
Do not
charge battery in rain, snow, damp or wet loca-
tions.
Do not use battery or charger in the pres-
ence of explosive atmospheres (gaseous fumes,
dust or flammable materials) because sparks may
be generated when inserting or removing battery,
possibly causing fire.
4.
CHARGE IN A WELL VENTILATED AREA.
Do
not block charger vents. Keep them clear to allow
proper ventilation. Do not allow smoking or open
flames near a charging battery. Vented gases
may explode.
5.
MAINTAIN CHARGER CORD.
When unplugging
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 dam-
aged cord or plug. Have a damaged cord replaced
immediately with identical replacement parts (see
“Maintenance”).
6.
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 fire 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 char-
ger. Make sure that the extension cord is in good
electrical condition.
7.
CHARGER IS RATED FOR 120 VOLT AC ONLY.
Charger must be plugged into an appropriate
receptacle.
8.
USE ONLY RECOMMENDED ATTACHMENTS.
Use of an attachment not recommended or sold
by the battery charger or battery manufacturer
may result in a risk of fire, electric shock or per
-
sonal injury.
9.
UNPLUG CHARGER
when not in use. Remove
battery from unplugged chargers.
10.
TO REDUCE THE RISK OF ELECTRIC SHOCK
,
always unplug charger before cleaning or main-
tenance. Use a Ground Fault Circuit Interrupter
(GFCI) to reduce shock hazards.
11.
DO NOT BURN OR INCINERATE BATTERIES.
Batteries may explode, causing personal injury or
damage. Toxic fumes and materials are created
when batteries are burned.
12.
DO NOT CRUSH, DROP, OR DAMAGE
bat-
teries. Do not use a battery 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).
13.
DO NOT DISASSEMBLE.
Incorrect reassembly
may result in the risk of electric shock, fire or
exposure to battery chemicals. If it is damaged,
take it to a MILWAUKEE service facility.
14.
BATTERY CHEMICALS CAUSE SERIOUS
BURNS.
Never allow contact with skin, eyes, or
mouth. If a damaged battery leaks battery chemi-
cals, use rubber or neoprene gloves to dispose of
it. If skin is exposed to battery fluids, wash with
soap and water and rinse with vinegar. If eyes
are exposed to battery chemicals, immediately
flush with water for 20 minutes and seek medical
attention. Remove and dispose of contaminated
clothing.
15.
DO NOT SHORT CIRCUIT.
A short-circuited
battery pack may cause fire, personal injury, and
product damage. 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.
16.
DO NOT ALLOW FLUIDS TO FLOW INTO BAT-
TERY PACK.
Corrosive or conductive fluids, such
as seawater, certain industrial chemicals, and
bleach or bleach containing products, etc., can
cause a short circuit..
17.
STORE YOUR BATTERY AND CHARGER
in a
cool, dry place. Do not store battery where tem-
peratures may exceed 120°F (50°C) such as in
direct sunlight, a vehicle or metal building during
the summer. Charger will charge
the battery when
the battery's internal temperature is between
14°F (-10°C) and 140°F (60°C). When the battery
temperature is outside that range, charging will
not occur.
