CHARGER OPERATION
WARNING
Charge only MILWAUKEE M12™
Lithium-Ion battery packs in the
MILWAUKEE Li-Ion Battery Charger. Other types
of batteries may cause personal injury and dam
-
age. Battery pack and charger are not compatible
with V™-technology or NiCd systems.
When to Charge MILWAUKEE Li-Ion
Battery Packs
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.
How to Charge the Battery Pack
Plug the Radio + Charger into a 120V outlet. The
battery packs will not charge if the Radio + Charger
is not plugged in. 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 battery pack with an internal tem
-
perature in the normal range will charge in about 30
to 185 minutes, depending on the battery pack.
• Heavily cycled batteries 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. Re
-
move the pack and reinsert. 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 pack and reinsert. If the light indicator still does
not come on, contact a MILWAUKEE service facility.

Changing Back-up Batteries
WARNING
Batteries may leak chemicals or
may explode if used incorrectly.
The following care should be taken to prevent
such an incident:
•Make sure the positive (+) and negative (-) bat
-
tery terminals are positioned correctly.
•Do not mix new and old batteries together, or
mix different types of batteries.
•Do not try to recharge non-rechargeable batteries.
If chemicals from the batteries come in contact
with your skin, wash them off immediately with
water. If chemicals leak onto the radio, clean the
radio completely.
Choking hazard. Keep batteries away from
children.
To hold station presets and clock time when the bat
-
tery pack is removed and the radio is unplugged, (2)
AAA batteries are required.
1. Remove battery pack and unplug radio.
2. Remove the screw and battery cover located
near the battery bay.
3. Insert two (2) AAA batteries according to
matching positive (+) and negative (-) marks.
4. Replace the battery cover and screw.

WARNING
To reduce the risk of fire, personal
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.
Cleaning
Clean out dust and debris from charger vents and
electrical contacts by blowing with compressed air.
Use only mild soap and a damp cloth to clean the
battery pack and charger, keeping away from all elec
-
trical contacts. Certain cleaning agents and solvents
are harmful to plastics and other insulated parts.
Some of these include gasoline, turpentine, lacquer
thinner, paint thinner, chlorinated cleaning solvents,
ammonia and household detergents containing am
-
monia. Never use flammable or combustible solvents
around battery packs, charger, or tools.
