CHARGING THE BATTERY
Note: Always switch to a fresh battery when tool performance begins to diminish.
Severe heat is most destructive to a battery; the more heat generated, the faster the
battery loses power. A battery that gets too hot can be permanently damaged. Never
over-discharge a battery by using the tool even after tool performance is decreasing.
Never attempt to discharge a tool’s battery by continuing to pull the tool trigger. When
tool performance begins to diminish, stop the tool, recharge the battery and
use the fresh battery for optimal performance.
1. When a Battery (47) requires recharging, a 3 to 5 hour* charge allows the tool to
operate at full power. Do not recharge the Battery longer than 5 hours*, as damage
to the Battery and/or tool will occur.
2. To charge the Battery (47), plug the AC Charger Adapter’s (53) plug into the Charger
(52). Insert the Charger (52) onto the top of the Battery (47) until it locks into place.
Charging room temperature: 50°
F - 104° F. Then, plug the AC Charger Adapter
into the nearest 120 Volt, grounded, electrical outlet. (See illustration below.)
3. Two Charging Indicator LEDs on the Charger (52) will illuminate to show that charging
is taking place. NOTE: The AC Charger Adapter (53) will not automatically turn off
when the Battery is fully charged, and the Charging Indicator LEDs will remain on
until the AC Charger Adapter is disconnected from the electrical outlet. Recharging
the Battery more than 5 hours* can cause damage to the battery cells.
4. While charging, the Battery (47), AC Charger Adapter (53), and/or Charger (52)
may become warm to the touch. This is normal, and does not indicate a problem.
5. Once the Battery (47) is fully charged, disconnect the AC Charger Adapter (53) from
the electrical outlet. Then, disconnect the Charger from the Battery.
* The Battery (47) require an initial charge time of 8 hours. Do not recharge the Battery more than 5
hours after this initial charging.
