OPERATION
CHARGING THE BATTERY PACK GENERAL
Before using your cordless tool for the first time, the battery pack should be
fully charged. If the battery pack is installed in the tool, remove it by following
instructions under INSTALLING OR REMOVING BATTERY PACK.
As a battery pack approaches the discharged state, you will notice a sharp
drop in tool performance. When the tool is unable to perform the task at hand,
it is time to recharge the battery pack. Recharging the battery pack before this
condition is reached will reduce the total work life of the pack. Discharging the
pack beyond this point can damage the pack.
Battery temperature will increase during and shortly after use.
Batteries may not accept a full charge if they are charged
immediately after use. Allow the battery pack to cool to room
temperature before charging for best results.
The battery charger may rest on the four pads provided on the bottom of the
case or be mounted on a wall by utilizing the two key hole slots provided.
Vent slots in top and bottom of charger must not be
obstructed. Do not charge battery when temperature is
BELOW 40°F (4.44°C) or ABOVE 104°F (40°C).
NORMAL CHARGING
Make sure that the power circuit voltage is the same as that shown on the
charger specification plate. Connect charger to power source. The green light
(A) Fig. 8 should begin to flash. This
indicates the charger is ready to begin
charging.
Position battery pack on charger, align
rails on battery pack with four tabs (C)
Fig. 8 on charger. Slide battery
forward on charger until it stops.
The green light (A) Fig. 8 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. 8 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 “Maintenance Charge” mode. The battery pack can be left on “Maintenance
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 Model 8604 charger is equipped with a diagnostic system that
automatically checks the battery pack when it is inserted into the charger. If
no problems are found, the charger will automatically switch to “Fast Charge”
mode as described in "NORMAL CHARGING".
