NORMAL CHARGING

Make sure power circuit voltage is the same as that shown on the charger specification
plate. Connect charger to power source. The green light (A) Fig. 1 should begin to flash.
This indicates the charger is ready to begin charging.
Position battery pack on charger. Align rails (A) Fig. 2 on battery pack with four tabs (C)
Fig. 1 on charger. Slide battery forward onto charger until it stops.
The green light (A) Fig. 1 should begin to glow continuously, indicating that the battery
pack is receiving a "Fast Charge" (if the green light does not glow continuously, or if the
red light (B) Fig. 1 also begins to flash, see DIAGNOSTICS). After approximately one
hour, the "Fast Charge" indicator light should go out indicating that the battery pack is
fully charged and that the charger is now in a "Trickle Charge" mode. The battery pack
can be left on "Trickle Charge" until you are ready to use it.
Depending on room temperature, line voltage, and existing charge level, initial battery
charging may take longer than one hour.
Disconnect charger from power source when not in use.
DIAGNOSTICS
The Models 8604 and 8624 Chargers are equipped with a diagnostic system that
automatically checks the battery pack each time a pack is inserted into the charger. If
no problems are found, the charger will automatically switch to "Fast Charge" mode as
described in NORMAL CHARGING. If a problem is found, it will be indicated by the
charger indicator lights (see Fig. 1) as follows:
• The green light (A) continuing to flash after battery pack is inserted in charger
indicates that the battery pack temperature is either too high or too low for charging.
If left alone, the charger will continue to monitor the battery pack temperature and will
begin charging when the temperature reaches an acceptable level.
•The green light (A) glowing continuously and the red light (B) flashing indicates the
battery pack is receiving a "Fast Charge", but the battery pack voltage is low. It is not
unusual for a new or a fully discharged battery pack to give this indication for the first
several minutes of charge. If the red light continues to flash throughout the charge
cycle, it indicates that the pack is weak and will provide reduced performance (the
pack is still useable, but will not provide maximum power or work per charge). This
battery pack will probably require replacement in the near future.
•The green light (A) continuing to flash and the red light (B) flashing indicates the
battery pack has failed (pack is not chargeable and requires replacement).
