Battery Charging Procedure
Your charger is designed to use standard 120 volt AC, 60 Hz power. Do
not use DC or any other voltage. Battery charge time is approximately 90
minutes. Charging is controlled by a microprocessor. Charger will charge
the battery when the battery’s temperature is between 32°F(0°C) and
113°F(45°C). When the battery temperature is outside that range, charging
will not occur. A hot or cold battery may take longer to charge.
1. Plug the charger into an appropriate outlet. The red LED and
green LED turn on simultaneously for about 1 second, then turn off,
indicating the charger is properly plugged in, ready to use. NOTE:
Do not charge by means of an engine generator or DC power
source. Use only 120VAC.
2. Insert the battery pack into the charger (Figure 1). Be sure the pack
is fully seated in the charger. The red (charging) light will turn on
and stay solid on indicating that the charging process has started.
3. The completion of charge will be indicated by the green light
coming on and staying solid on. The battery pack is fully charged
and may be used at this time or left in the charger.
4. Unplug charger, and remove the battery pack. Place the battery
pack in the tool and be certain that it is inserted fully into the tool
cavity until it “clicks” into place.
BATTERY PACK NOTES:
1. If the battery pack is abused and/or battery voltage is under
specification (such as over discharge), the red LED will blink
immediately after the battery pack is seated in the charger. This
does not indicate a failure. Charging is ongoing at low charge
current in this case. The red LED will turn into solid on in 15 minutes
indicating start of normal charge.
2. When a hot battery (internal temperature more than 113°F (45°C))
is inserted into charger, the red LED will keep on flashing until the
temperature drops to acceptable level for normal charge.
