WARNING
Li-Ion batteries in the MILWAUKEE
12V Li-Ion charger. Other types of batteries may
cause personal injury and damage.
When to Charge the Battery Pack
with these MILWAUKEE Chargers
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 (on the tool) 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 (battery pack
is too hot or cold) or continuous (pack is charging).
• Charge time depends on capacity of battery pack.
Heavily cycled batteries may take longer to charge
completely.
• 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. Remove
the battery pack and reinsert. If the light continues
to flash red and green, remove pack and unplug
charger for at least 2 minutes. After 2 minutes,
plug charger back in and insert pack. If the problem
persists, 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 battery pack and reinsert. If the light indicator still
does not come on, remove pack and unplug charger
for at least 2 minutes. After 2 minutes, plug charger
back in and insert pack. If the light indicator still does
not come on, contact a MILWAUKEE service facility.
Charging a Hot or Cold Battery Pack
The red flashing indicator light on the charger indi-
cates that the battery pack temperature is outside the
charging range. Once the battery pack is within the
acceptable range, normal charging will take place
and the red light will be continuous. Hot or cold bat-
teries may take longer to charge.

MAINTENANCE

To reduce the risk of fire, personal
WARNING
injury, and product damage due to
a short circuit, never immerse a 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.
Always unplug the charger and remove the
battery from the charger before performing any
maintenance. Never disassemble the battery or
charger. Contact a MILWAUKEE service facility
for ALL repairs.
Do not expose battery packs, chargers or tools to
fluids, water, or rain, or allow them to get wet. This
could damage the tool, charger, and/or battery pack.
Clean out dust and debris from tool, charger and bat-
tery vents and electrical contacts by vacuuming or
brushing. Clean housings with a damp, soapy cloth,
keeping away from all electrical contacts. Certain
cleaners and solvents, such as gasoline, turpentine,
lacquer thinner, paint thinner, bleach, chlorinated
cleaning solvents, ammonia and household deter-
gents containing ammonia, are harmful to plastics
and other insulated parts; plastic casings will become
brittle and crack. Never use flammable or combus-
tible solvents around batteries, charger, or tools.
Store your charger in a cool, dry place.
As a general practice, it is best to unplug chargers
and remove battery packs when not in use, however,
no damage to the battery pack will occur. Store at
room temperature away from moisture. Store bat-
teries upright. Do not store in damp locations where
corrosion of terminals may occur. Storing in high
temperatures (over 120°F) for long periods can result
in permanent capacity loss for any battery. Charge
before use after storing for long periods.
The charger has no serviceable parts.
