CHARGING THE BATTERY
Before using your cordless tool for the first time, fully charge the battery
pack. If the battery pack is installed, remove it by following instructions under
"INSTALLING OR REMOVING BATTERY PACK".
NORMAL CHARGING
Make sure that the power circuit voltage is the same as that shown on the
charger specification plate. Connect the charger to the power source. The red
and green lights will flash once to indicate that the power is connected properly
and the charger is ready for operation.
Position the battery pack on charger and align the rails on the battery pack (A)
Fig. 2 with the four tabs (C) Fig. 1 on the charger. Slide the battery forward on
charger until it stops.
The green light (A) Fig. 1 should begin to flash rapidly indicating that the battery
pack is receiving a “fast charge”. [If the green light does not flash or if the red
light (B) illuminates, see "DIAGNOSTICS"]. After approximately one hour, the
“Fast Charge” indicator light should glow continually, 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 the charger from the power source when not in use.
Always set the trigger switch to the locked "OFF" position when installing or
removing the battery pack.
To remove the battery pack, depress the battery release button (B) Fig. 2, and
pull the battery pack out of the tool.
To install the battery pack, align the rails (A) Fig. 2 of the battery pack with the
slots on the tool. Push the battery pack on the tool until it locks in place.
