blink. The charger will no longer work and should be returned to an
authorized service center or replaced.
LEAVING THE BATTERY IN THE CHARGER
The charger and battery pack can be left connected with the red
lights glowing indefinitely. The charger will keep the battery pack
fresh and fully charged. This charger features an automatic tune-up
mode which equals or balances the individual cells in the battery
pack to allow it to function at peak capacity. Battery packs should
be tuned up weekly or whenever the battery no longer delivers the
same amount of work. To use the automatic tune-up mode, place the
battery pack in the charger and leave it for at least 8 hours.
Important Charging Notes
1. Longest life and best performance can be obtained if the battery
pack is charged when the air temperature is between 65°F and
75°F (18°- 24°C). DO NOT charge the battery pack in an air
temperature below +40°F (+4.5°C), or above +105°F (+40.5°C).
This is important and will prevent serious damage to the battery
pack.
2. The charger and battery pack may become warm to touch while
charging. This is a normal condition, and does not indicate a
problem. To facilitate the cooling of the battery pack after use,
avoid placing the charger or battery pack in a warm environment
such as in a metal shed, or an uninsulated trailer.
3. If the battery pack does not charge properly:
a. Check current at receptacle by plugging in a lamp or other
appliance
b. Check to see if receptacle is connected to a light switch which
turns power off when you turn out the lights.
c. Move charger and battery pack to a location where the
surrounding air temperature is approximately 65°F - 75°F
(18° - 24°C).
d. If charging problems persist, take the tool, battery pack and
charger to your local service center.
4. The battery pack should be recharged when it fails to produce
sufficient power on jobs which were easily done previously. DO
NOT CONTINUE to use under these conditions. Follow the
charging procedure. You may also charge a partially used pack
whenever you desire with no adverse affect on the battery pack.
5. Foreign materials of a conductive nature such as, but not limited
to, grinding dust, metal chips, steel wool, aluminum foil, or any
buildup of metallic particles should be kept away from charger
cavities. Always unplug the charger from the power supply when
there is no battery pack in the cavity. Unplug charger before
attempting to clean.
6. Do not freeze or immerse charger in water or any other liquid.
WARNING: Shock hazard. Do not allow any liquid to get inside
charger.
CAUTION: To reduce the risk of personal injury, NEVER attempt to
open the battery pack for any reason. If the plastic housing of the
battery pack breaks or cracks, return to a service center for recycling.
Installing and Removing the Battery
Pack (Fig. 1)
NOTE: Make sure your battery pack is fully charged.
WARNING: To reduce the risk of serious personal injury,
make certain the lock-off button (B), as shown on page 13,
is engaged to prevent switch actuation before removing or
installing battery.
To install the battery pack into the tool handle, align the base of
the tool with the rails inside the tool's handle and slide the battery
pack firmly into the handle until you hear the lock snap into place.
To remove the battery pack from the tool, press the release button
(J) and firmly pull the battery pack out of the tool handle. Insert it into
the charger as described in the charger section of this manual.
