Cold Weather Operation

MILWAUKEE Li-Ion battery packs are designed to
operate in temperatures below freezing. When the
battery pack is too cold, it may need to warm up
before normal use. Put the battery on a tool and use
the tool in a light application. It may "buzz" for a short
time until it warms up. When the buzzing stops, use
the tool normally.
To reduce the risk of fire, personal
WARNING
injury, and product damage due to
a short circuit, never immerse your tool, battery
pack or charger in fluid or allow a fluid to flow
inside them. Corrosive or conductive fluids, such
as seawater, certain industrial chemicals, and
bleach or bleach containing products, etc., can
cause a short circuit.

Maintenance and Storage

Do not expose your battery pack or cordless tools
to water or rain, or allow them to get wet. This could
damage the tool and battery pack. Do not use oil or
solvents to clean or lubricate your battery pack. The
plastic casing will become brittle and crack, causing
a risk of injury.
Store battery packs at room temperature away from
moisture. Do not store in damp locations where cor-
rosion of terminals may occur. As with other battery
pack types, permanent capacity loss can result if
the pack is stored for long periods of time at high
temperatures (over 120° F). MILWAUKEE Li-Ion
battery packs maintain their charge during storage
longer than other battery pack types. After about a
year of storage, charge the pack as normal.
Transport
Personal transport of Li-Ion battery packs is allowed
when done in accordance with these warnings and
instructions. The proper classification, packaging,
labeling, marking, and documentation requirements for
shipping Li-Ion batteries is dependent upon whether
the particular batteries are rated greater than or less
than 100 Wh. Generally, Li-Ion batteries rated 100 Wh
or less are "excepted" from certain Class 9 DG require-
ments. Always check compliance of Li-Ion battery con-
signments against the current regulations governing
the chosen mode of transport. When in doubt, contact
the carrier or other trained Dangerous Goods profes-
sional to confirm acceptability. Li-Ion packs are shipped
under classification UN 3480 (battery only) or UN 3481
(batteries contained in or packed with equipment).
To reduce the risk of injury or ex-
WARNING
plosion, never burn or incinerate a
battery pack even if it is damaged, dead or com-
pletely discharged. When burned, toxic fumes
and materials are created.
Disposing of MILWAUKEE Li-Ion
Battery Packs
MILWAUKEE Li-Ion battery packs are more environ-
mentally friendly than some other types of power tool
battery packs (e.g., nickel-cadmium). Always dispose
of your battery pack according to federal, state and
local regulations. Contact a recycling agency in your
area for recycling locations.
Even discharged battery packs contain some energy.
Before disposing, use electrical tape to cover the
terminals to prevent the battery pack from shorting,
which could cause a fire or explosion.
RBRC Battery Recycling Seals
The RBRC™ Battery Recycling Seals (see "Sym-
bology") on your tool battery packs indicate that
MILWAUKEE has arranged for the recycling of
that battery pack with the Rechargeable Battery
Recycling Corporation (RBRC). At the end of your
battery pack's useful life, return the battery pack to
a MILWAUKEE Branch Office/Service Center or the
participating retailer nearest you. For more informa-
tion, visit the RBRC web site at www.rbrc.org.

WARNING
Li-Ion batteries in this MILWAUKEE
Li-Ion charger. Other types of batteries may cause
personal injury and damage.
When to Charge the Battery Pack
with this MILWAUKEE Charger
Remove the battery pack from the tool for charging
when convenient for you and your job. MILWAUKEE
batteries do not develop a "memory" when charged
after only a partial discharge. It is not necessary to run
down the battery pack before placing it on the charger.
• Use the Fuel Gauge to determine when to charge
your MILWAUKEE Li-Ion battery pack.
• You can "Top-Off" your battery pack's charge before
starting a big job or long day of use.
• The only time it is necessary to charge the
MILWAUKEE Li-Ion battery pack is when the battery
pack has reached the end of its charge. To signal
the end of charge, power to the tool will drop quickly,
allowing you just enough power to finish making a
cut, drilling a hole, or driving a fastener. Charge the
battery pack as needed.
How to Charge the Battery Pack
Align the battery pack with the bay and slide the
battery pack into the charger as far as possible. The
red light will come on, either flashing quickly (bat-
tery pack is too hot or cold), flashing slowly (battery
pack is waiting for another pack to finish charging)
or continuous (pack is charging).
• The 48-59-1806 charges six batteries in sequence
in a counter-clockwise rotation.
• The next pack inserted in the charger will begin
charging when the previous pack is fully charged.
To skip a pack and move to the next pack, press the
skip button
.
• A fully discharged battery pack with an internal
temperature in the normal range will charge in 30
to 185 minutes, depending on the battery pack.
• Heavily cycled batteries may take longer to charge
completely.
• The Fuel Gauge lights on 18V battery packs are
displayed as the pack is being charged, indicating
how fully charged the pack is. The fuel gauge will
turn off when charging is complete.
• After charging is complete, the continuous green
light will come on.
• The charger will keep the battery pack fully charged
if it is left on the charger.
• If the light indicator flashes red and green, check
that the battery pack is fully seated into the bay.
