Maintenance - Milwaukee M18 48-59-1815 Operator's Manual

• 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(s) and unplug
charger for at least 2 minutes. After 2 minutes,
plug charger back in and insert pack. If after these
attempts the light indicator still does not come on,
contact a MILWAUKEE service facility.
• If the light indicator double blinks red slowly (while
no pack is inserted), one or more fans are damaged.
The battery pack will not cool while charging, and will
charge at a reduced rate. 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.

COOL-CYCLE™ Fans
• The COOL-CYCLE™charger is designed to cool
the battery packs while charging.
• For best results, COOL-CYCLE™ capabilities are
best paired with COOL-CYCLE™ capable battery
packs.
• Once battery pack is inserted, the COOL-CYCLE™
fans will turn on and may continue cooling the battery
pack after it is charged.
• The COOL-CYCLE™ fans may not turn on or spin
slower if the battery pack is cool.
• Some older battery packs may cause fans to run
continuously. This is normal and will not damage
the battery pack or charger.
• If the charge light indicators slowly pulse red with
no battery pack installed, the COOL-CYCLE™ fan
is damaged, contact a MILWAUKEE service facility.

or Generator
The charger will operate with most 120-127 V gen-
erators and inverters rated at 500 Watts or higher.

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.
Cleaning
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.
