OPERATION
Diagnostic Feedback
See Figure 1, page 9.
LEDs provide feedback to indicate whether the battery pack is
charging, fully charged, or defective.
Key Hole Hanger
See Figure 2, page 9.
The charger has a key hole hanging feature for convenient,
space saving storage. Screws should be installed so that the
center distance is 2 - 3/8 in.
Charging
See Figure 3, page 9.
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 your battery pack under
normal circumstances, return both the battery pack and charger
to your nearest repair center for electrical check.
Charge time is approximately 40 minutes, and is dependent
upon the type of battery pack.
• Make sure the power supply is normal household voltage,
110V, 60Hz.
• 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.
• Press down on the battery pack to be sure contacts on the
battery pack engage properly with contacts in the charger.
• Do not place the charger in an area of extreme heat or cold.
It will work best at normal room temperature.
• 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 while
the charger is in 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.
• To remove the battery pack from the charger, 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 orange LED will begin
flashing and the green LED will be off. When the battery pack
cools, the charger will automatically begin charging.
Charging a Cold 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 orange LED will begin flashing
and the green LED will be off. When the battery pack warms, the
charger will automatically begin charging.
