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 18 °- 24 °C (65 °F - 75 °F).
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. Under certain conditions, with the charger plugged into the power supply, the
exposed charging contacts inside the charger can be shorted by foreign material.
Foreign materials of a conductive nature such as, but not limited to, 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. Don’t allow any liquid to get inside charger. Electric
shock may result.
CAUTION: 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.
Storage Recommendations
1. The best storage place is one that is cool and dry away from direct sunlight and
excess heat or cold.
2. Long storage will not harm the battery pack or charger. Under proper conditions,
they can be stored for 5 years or more.
SAVE THESE INSTRUCTIONS FOR FUTURE USE.
HOT/COLD PACK DELAY
Some chargers have a Hot/Cold Pack Delay feature: when the charger detects a
battery that is hot, it automatically starts a Hot Pack Delay, suspending charging
until the battery has cooled. After the battery has cooled, the charger automatically
switches to the Pack Charging mode. This feature ensures maximum battery life. The
red light flashes long, then short while in the Hot Pack Delay mode.
PROBLEM POWER LINE
Some chargers have a Problem Power Line indicator. When the charger is used with
some portable power sources such as generators or sources that convert DC to AC, the
charger may temporarily suspend operation, flashing the red light with two fast blinks
followed by a pause . This indicates the power source is out of limits.
LEAVING THE BATTERY PACK IN THE CHARGER
The charger and battery pack can be left connected with the red light glowing
indefinitely. The charger will keep the battery pack fresh and fully charged.
NOTE: A battery pack will slowly lose its charge when kept out of the charger. If the
battery pack has not been kept on maintenance charge, it may need to be recharged
before use. A battery pack may also slowly lose its charge if left in a charger that is
not plugged into an appropriate AC source.
WEAK BATTERY PACKS: Chargers can also detect a weak battery pack. Such
batteries are still usable but should not be expected to perform as much work. The
charger will indicate to replace battery pack.
Important Charging Notes
1. Longest life and best performance can be obtained if the battery pack is charged
when the air temperature is between 18 °- 24 °C (65 °F and 75 °F). DO NOT
charge the battery pack in an air temperature below +4.5 °C (+40 °F), or above
+40.5 °C (+105 °F). 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.
