Battery Pack Protection
To protect itself from damage and extend its life,
the battery pack's intelligent circuit monitors current
draw and temperature. In extremely high torque,
binding, stalling, and short circuit situations, the
battery pack will turn OFF the product if the current
draw becomes too high. The fuel gauge will flash.
Release the trigger, wait for the fuel gauge to stop
flashing, and then restart.
Under extreme circumstances, the internal tem-
perature of the battery could become too high. If
this happens, the fuel gauge lights will flash in an
alternating pattern and the tool will not run. Allow the
battery to cool down.

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 product and
use the product in a light application.
To reduce the risk of injury or ex-
WARNING
plosion, never burn or incinerate
a battery pack even if it is damaged, dead or
completely discharged. When burned, toxic
fumes and materials are created.
Disposing of MILWAUKEE Li-Ion Battery
MILWAUKEE Li-Ion batteries are more environmen-
tally friendly than some other types of power tool
batteries. Always dispose of your battery according
to federal, state and local regulations. Contact a
recycling agency in your area for recycling locations.
Even discharged batteries contain some energy.
Before disposing, use electrical tape to cover the
terminals to prevent the battery from shorting, which
could cause a fire or explosion.
RBRC Battery Recycling Seals
The RBRC™ Battery Recycling Seals (see "Symbol-
ogy") on your batteries indicate that MILWAUKEE
has arranged for the recycling of that battery with
the Rechargeable Battery Recycling Corporation
(RBRC). At the end of your battery's useful life,
return the battery to a MILWAUKEE Branch Office/
Service Center or the participating retailer nearest
you. For more information, visit the RBRC web site
at www.rbrc.org.

SUPER CHARGER
Charge only MILWAUKEE M18™
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 charg-
ing when convenient. 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
COOL-CYCLE™ fans will turn on. The red light will
come on, either flashing quickly (battery pack is too
hot or cold), flashing slowly (battery pack is waiting
for another pack to finish charging) or continuous
(pack is charging).
• A fully discharged battery pack with an internal tem-
perature in the normal range will charge in about 15
to 130 minutes, depending on the battery pack and
internal temperature of the charger.
• Heavily cycled batteries may take longer to charge
completely.
• Super charge occurs when the battery pack is
charging above 9 A. The CHARGE ADAPT™ light
indicator will illuminate when a battery pack is super
charging. If charging two battery packs capable of
12 amp charging, the charger will charge the first
pack at 12 A, and the second battery pack will charge
at 6 A. Once the first battery pack is fully charged
(charge indicator light is solid green), the second
battery pack will charge at up to 18 A until it's fully
charged.
• 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.
• 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(s) 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.
