Charge Indicators
This charger is designed to detect certain problems that can arise. Problems are indicated
by the red light flashing at a fast rate. If this occurs, re-insert the battery pack into the
charger. If the problem persists, try a different battery pack to determine if the charger
is working properly. If the new pack charges correctly, then the original pack is defective
and should be returned to a service center or other collection site for recycling. If the new
battery pack elicits the same trouble indication as the original, have the charger and the
battery pack tested at an authorized service center.
HOT/COLD DELAY
This charger has a hot/cold delay feature: when the charger detects a battery that is hot,
it automatically starts a 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/cold delay mode.
LEAVING THE BATTERY PACK IN THE CHARGER
The charger and battery pack can be left connected with the charge indicator showing
Pack Charged.
WEAK BATTERY PACKS:
Weak batteries will continue to function but should not be
expected to perform as much work.
FAULTY BATTERY PACKS:
This charger will not charge a faulty battery pack. The charger
will indicate faulty battery pack by refusing to light or by displaying problem pack or charger.
NOTE:
This could also mean a problem with a charger.
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.
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 the 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 operation of 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 the 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 effect 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 the charger before attempting to clean.
6. Do not freeze or immerse the charger in water or any other liquid.
