fi re and/or serious personal injury.
SAVE THESE INSTRUCTIONS
This operator's manual contains important safety and operating instructions for the MILWAUKEE
Li-Ion/NiCd Multi-Bay Charger. Before using the charger , read this operator's manual, your tool
and battery operator's manuals, and all labels on the battery pack, charger and tool.
1. CAUTION! TO REDUCE THE RISK OF
INJURY , CHARGE MIL WAUKEE LITHIUM-ION PACKS ONL Y IN MILWAUKEE
LITHIUM-ION CHARGERS. CHARGE
MILWAUKEE NiCd PACKS ONLY IN
MILWAUKEE NiCd CHARGERS. Other
types of chargers may cause personal
injury or damage.
2. AVOID DANGEROUS ENVIRON-
MENTS. Do not charge battery pack in
rain, snow, damp or wet locations. Do
not use battery pack or charger in the
presence of explosive atmospheres
(gaseous fumes, dust or flammable
materials) because sparks may be
generated when inserting or removing
battery pack, possibly causing fi re.
3. CHARGE IN A WELL VENTILATED

TOOL USE AND FEATURES
Multi-Bay, Multi-Voltage, Multi-Chemistry
The independent bays on the Multi-Bay
Charger allow for charging up to 3 batteries
at the same time. The batteries can be different voltages (12 to 28 Volts) and different
chemistries (NiCd or Li-Ion). For example,
charge your 12 Volt NiCd battery, 18 Volt
NiCd battery, and 28 Volt Li-Ion battery all
6
6
at once.
Cord Wrap/Pass-Through Plug
A convenient cord wrap stores the 9-foot
cord. A pass-through plug keeps an outlet
available for other uses.
Job Site Built
The rugged housing of the Multi-Bay Charger
is well suited for the harsh environment of
job sites. Roll bars and blow-molded plastic
protect the charger during falls and bumps.
The high visibility bright indicator lights are
mounted on top of the charger for 360°
viewing.
Dust covers on the electrical contacts help
keep the dust and debris of job sites out of
the charger. When a battery pack is inserted,
the dust covers automatically retract to allow
charging.
Battery packs can be stored on the bays and
carried on the charger from job to job. When
the charger is plugged in, charging begins for
the packs on the bays.

CHARGER OPERATION
WARNING
Charge only MILWAUKEE 18-28V
Lithium-Ion battery packs and
MILWAUKEE 12-18V NiCd battery
packs in the MILWAUKEE Li-Ion/NiCd
Multi-Bay Battery Charger. Other
types of batteries may cause personal
injury and damage.
When to Charge the Battery Pack
For MILWAUKEE NiCd Battery Packs:
Charge your battery pack overnight before
you use it for the fi rst time and then when
your tool no longer performs with the power
and torque needed for the job. Never completely discharge the battery pack.
New battery packs reach full loading capacity after 2-10 chargings and dischargings.
Battery packs which have not been used
for some time should be recharged before
use.
For MILWAUKEE Li-Ion Battery Packs:
Remove the battery pack from the tool for
charging when convenient for you and your
job. MILWAUKEE battery packs 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 bat-
tery 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 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 fi nish 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 come on, either fl ashing (pack
is too hot or cold) or continuous (pack is
charging).
• For MILWAUKEE Li-Ion battery packs,
the Fuel Gauge lights on the battery
pack are displayed as the pack is being
charged, indicating how fully charged
the pack is.
• A fully discharged pack with an internal
temperature in the normal range* will
charge a NiCd battery pack in 45 minutes or less and a Li-Ion battery pack
in 60 minutes or less. Heavily cycled
battery packs may take longer to charge
completely.
*Normal Range: For Li-Ion, between
32°F and 150°F; for NiCd, between
32°F and 140°F)
• Three battery packs can be charged
simultaneously with no change in charging times.
• After charging is complete, the continuous green light will come on. For
MILWAUKEE Li-Ion packs, the Fuel
Gauge lights will go off. The Fuel Gauge
button won't work when the pack is on
the charger.
• The charger will keep the battery pack
fully charged if it is left on the charger.
• After the battery is completely charged,
the charger will continue conditioning
("topping-off") the battery to hold a
stronger charge. Over time, batteries
begin to hold less and less charge.
The "top-off" mode helps renew the
charge-life of the battery. This process
can take from 1 to 4 hours, depending
on the battery temperature. The battery
may be removed at any point during this
cycle with no harm done.
• 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 light continues
to fl ash red and green, the battery pack
may be extremely hot or cold, or wet.
Allow the pack to cool down, warm up, or
dry out and then 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.
Charging a Hot or Cold Battery Pack
The Red Flashing Indicator light on the
charger indicates that the battery pack
temperature is outside the charging range.
Once the pack is within the acceptable range,
normal charging will take place and the red
light will be continuous. Hot or cold battery
packs may take longer to charge.

Maintenance and Storage
Store your charger in a cool, dry place.
As a general practice, it is best to unplug
battery chargers and remove battery packs
when not in use. No battery pack damage
will occur, however , if the charger and battery
pack are left plugged in.
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 electrical 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 ammonia. Never use
fl ammable or combustible solvents around
battery packs, charger, or tools.
Repairs
The MILWAUKEE Li-Ion/NiCd charger has
no internal serviceable parts. For cordset
repairs, return the charger to the nearest
authorized service center.
