OPERATION
CHARGING
See Figure 1, page 7.
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.
Charge time is approximately 8 hours and is dependent upon
the type of battery pack.

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.
 Press down on the charger to be sure contacts on
the battery pack engage properly with contacts in the
charger. Latches should snap into place to ensure charger
is correctly connected.
 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.
 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 the sides of the battery pack and separate
battery from charger.
