APPLICATIONS
You may use this product for the purpose listed below:
 Charging and maintaining compatible 12 V-19.2 V
nickel-cadmium battery packs
CAUTION:
If at any point during the charging
process none of the LEDs are lit, remove the bat-
tery pack from the charger to avoid damaging the
product. DO NOT insert another battery. Return the
charger and battery to your nearest authorized ser-
vice center for service or replacement.
CAUTION:
Charge in a well ventilated area. Do not
block charger vents. Keep them clear to allow proper
ventilation.
CHARGING A BATTERY PACK
See Figures 2 and 3, page i.
Battery packs are shipped in a low charge condition to
prevent possible problems. Therefore, you should charge
them before first use. If the charger does not charge the
battery pack under normal circumstances, return both the
battery pack and charger to your nearest repair center for
electrical check.
 Make sure the power supply is normal household
voltage, 120 volts, AC only, 60 Hz.
 Connect the charger to a power supply.
 Attach the battery pack to the charger by aligning the
raised ribs on the battery pack with the grooves in the
charger, then slide the battery pack onto the charger.

OPERATION

 Press down on the battery pack to be sure contacts on
the battery pack engage properly with contacts in the
charger.
 Latches should snap into place to ensure battery is
correctly connected.
 Do not place the charger in an area of extreme heat or
cold. It will work best at normal room temperature.
NOTE: The charger and battery pack should be placed
in a location where the temperature is more than 50°F
but less than 96°F.
 The battery pack may become slightly warm to the
touch while charging. This is normal and does not
indicate a problem.
 After charging is complete, the green LED will remain
on for one hour, indicating Maintenance Mode.
 After completing maintenance mode, the green LED
will begin fading on/off continuously. This indicates the
battery is fully charged and the charger is in Energy
Save Mode.
 Charger will periodically wake from Energy Save mode
to ensure the battery pack remains in a fully charged
state.
 To remove the battery pack from the charger, depress
the latches on both sides of the battery pack and pull
up on the battery pack.
CHARGING A HOT BATTERY PACK
When using a tool continuously, the battery pack may
become hot. A hot battery pack may be placed directly
onto the charger port but charging will not begin until
the battery temperature cools to within acceptable
temperature range. When a hot battery pack is placed
on the charger, the red LED will begin flashing and the
green LED will be off. When the battery pack cools to
approximately 120°F (40°C), the charger will automatically
begin charging.
CHARGING A COOL BATTERY PACK
A cold battery pack may be placed directly onto the
charger port but charging will not begin until the battery
temperature warms to within acceptable temperature
range. When a cold battery pack is placed on the charger,
the red LED will begin flashing and the green LED will be
off. When the battery pack warms to approximately 32°F
(0°C), the charger will automatically begin charging.
