Cold Weather Operation
MILWAUKEE Lithium-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 tem-
peratures (over 120° F). MILWAUKEE Lithium-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, la-
beling, 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 (Watt Hours can be found on the battery
pack nameplate). Generally, Li-Ion batteries rated
100 Wh or less are "excepted" from certain Class 9
DG requirements. Always check compliance of Li-Ion
battery consignments against the current regulations
governing the chosen mode of transport. When in
doubt, contact the carrier or other trained Dangerous
Goods professional 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.
Disposal
MILWAUKEE Lithium-Ion battery packs are more
environmentally 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 re-
cycling 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.
CHARGER
OPERATION
Charge only MILWAUKEE 28 Volt
WARNING
Lithium-Ion battery packs in
MILWAUKEE 28 Volt Li-Ion Battery Chargers.
Other types of batteries may cause personal in-
jury 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 Lithium-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 Lithium-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
Place the battery pack onto the bay by sliding the
pack on from the top of the bay. The red light will
turn on, either flashing (pack is too hot or cold) or
continuous (pack is charging).
• A fully discharged pack with an internal tempera-
ture between 32°F and 150°F will charge in about
1-Hour.
• Heavily cycled battery packs may take longer to
charge completely.
• The Fuel Gauge lights on the battery pack are
displayed as the pack is being charged, indicating
how fully charged the pack is.
• After charging is complete, the continuous green
light will turn on and the fuel gauge will turn off.
• 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.
Remove the pack and reinsert. If the problem per-
sists, contact a MILWAUKEE service facility.
• If the light indicator does not come on, check that
the battery pack is fully seated into the bay. Remove
the pack and reinsert. If the light indicator still does
not come on, contact a MILWAUKEE service facility.
